ICT Syllabus","heading":"","page":4,"text":"1.0 Introduction\nInformation and Communication Technology has been identified worldwide as a tool that can be used to improve productivity,\nefficiency and effectiveness of organizational work and the daily activities of individuals. Therefore, providing an adequate level of ICT\nknowledge and skills, at different levels of education, is important for the students to progress and contribute towards national\ndevelopment.\nThe current Sri Lankan Secondary Education System has been substantially exposed to ICT through various programs including CAL,\nICT for GCE (O/L), GIT at grade 12 and ICT as a component in A/L Technology stream. Consequently, students have shown a\ngrowing interest in ICT education and some have, in fact, performed excellently at international competitions in ICT, proving their high\nlevel of competence.\nICT as a main subject for GCE (A/L) was introduced in 2007.

subject; it is also a living subject. It is necessary to update one’s\nknowledge in order to be alert to the latest findings in this area. ICT has taken such an important position that the percentage of\nliteracy in ICT has come to be regarded as an index of development. It is essential that the proposed method of teaching should be\nstudent-centered as this subject is essentially practice-oriented. In view of the fact that this is an essentially practical subject, it is vital\nthat a student is involved in self study apart from the day to day learning- teaching process in order to ensure that subject matter\nlearned is firmly grasped.

Direct students to acquire knowledge and information through reliable sources wherever necessary.\n9.0 School Policies and Programs\nIt needs to be noted at the onset, that the success of the classroom learning-teaching process has an immense bearing on the\neffective actualization of the expected aims of the subject Information and Communication Technology. Therefore, it is important that\nthe school policy and programs are organized in keeping with these expectations. It is important, in the achievement of the aims of this\nsubject that the novelty of the subject and the consequent paucity of knowledge regarding this subject in student, should be taken into\nconsideration.\nThe number of periods available for this subject is 300 per year.

12 Teacher's Guide","heading":"","page":4,"text":"Message from the Director General\nWith the primary objective of realizing the National Educational Goals recommended by\nthe National Education Commission, the then prevalent content based curriculum was\nmodernized, and the first phase of the new competency based curriculum was introduced\nto the eight year curriculum cycle of the primary and secondary education in Sri Lanka in\nthe year 2007\nThe second phase of the curriculum cycle thus initiated was introduced to the education\nsystem in the year 2015 as a result of a curriculum rationalization process based on\nresearch findings and various proposals made by stake holders.\nWithin this rationalization process the concepts of vertical and horizontal integration have\nbeen

efficiency and effectiveness of organizational work\nand the daily activities of individuals. Therefore, providing an adequate level of ICT\nknowledge and skills, at different levels of education, is important for the students to\nprogress and contribute towards national development.\nThe current Sri Lankan Secondary Education System has been substantially exposed to\nICT through various programs including CAL, ICT for GCE (O/L), GIT at grade 12 and ICT\nas a component in A/L Technology stream. Consequently, students have shown a\ngrowing interest in ICT education and some have, in fact, performed excellently at\ninternational competitions in ICT, proving their high level of competence.\nICT as a main subject for GCE (A/L) was introduced in 2007.

According to the syllabus revising policy the syllabus was revised in 2017. GCE\n(O/L) qualified students who are interested in developing their career path in ICT, have the\nopportunity of learning it at the GCE (A/L). ICT as a subject for A/L would set a national\nstandard in ICT education at school level and provide the path to higher education at\ntertiary level. Furthermore, students who fail to earn a placement in a university would be\nin possession of a substantial foundation to build up their academic and professional\ncareers.\nThe ICT syllabus at GCE (A/L) communicates core concepts of ICT covering both\ntheoretical and practical usage of ICT.

also a\nliving subject. It is necessary to update one’s knowledge in order to be alert to the latest\nfindings in this area. ICT has taken such an important position that the percentage of\nliteracy in ICT has come to be regarded as an index of development. It is essential that the\nproposed method of teaching should be student-centered as this subject is essentially\npractice-oriented. In view of the fact that this is an essentially practical subject, it is vital\nthat a student is involved in self study apart from the day to day learning - teaching\nprocess in order to ensure that subject matter learned is firmly grasped.

day to day life. To make plans, schedules,\nand policies information are needed. Today’s information would helpful to predict how it\nwould be in the future. For an example, present information on currency exchange would\nbe helpful to predict that for the following month or for the following year.\nData processing and information creation can be done manually. Some drawbacks occur\nsuch as consuming more time in entering and organizing data manually. Also, human\nerrors in data processing may lead to inaccurate information.

to allow continued\ncommunication if one or more sites were destroyed. In the beginning ARPANET served\nonly computer professionals, engineers, and scientists who knew their way around its\ncomplex workings. Today, the Internet is a public, cooperative, and self-sustaining facility\naccessible to millions of people worldwide. Physically, the Internet uses a portion of the\ntotal resources of the currently existing public telecommunication networks. The Internet\nuses a set of protocols called TCP/IP (Transmission Control Protocol/Internet Protocol). A\nprotocol is an agreement or law behind the data transmission over networks.

A Cloud is present at a remote location\nand provides services over a network. Applications such as e-mail, web conferencing,\ncustomer relationship management (CRM) run in clouds. Cloud Computing refers to\nmanipulating, configuring, and accessing the applications online. It offers online data\nstorage, infrastructure and application. Cloud Computing provides access to applications\nas utilities, over the Internet.\nThere are reference models on which the Cloud Computing is based. These can be\ncategorized into three basic service models as listed below:\n1. Infrastructure as a Service (IaaS) - provides access to fundamental resources such as\nphysical machines, virtual machines, virtual storage, etc.\nEx - Customer Relationship Management, games, virtual desktop applications\n2.

ware.\nComputer Hardware\nHardware components can be categorised into Input Devices, Output Devices, Processing\nDevices, Networking Devices and Memory Devices. In addition to those types of hardware\nthere is a circuit board located inside a computer system called mother board by means of\nwhich every hardware component are connected to each other.\nInput Devices\nInput Devices correspond to input data into the computer system. Mouse, Trackball,\nJoystick, Touch pad, Touch screen and Light pen can be considered as pointing devices\nwhich are related to point out and select pixels on the screen. Keyboard is the most\ncommon and very popular input device which is used to input data to the computer.

printers\n41","vector":[0.0072,0.05284,-0.19854,-0.035,0.03305,0.01539,0.02334,-0.04636,-0.01529,-0.04233,0.05173,0.06785,0.06412,0.06526,-0.02684,-0.05155,-0.00656,-0.04897,0.02854,0.03048,-0.0346,-0.01724,-0.04782,-0.06614,0.02618,0.04468,-0.00853,0.0009,-0.02552,0.00162,0.02037,-0.00533,0.04332,-0.07218,0.00219,-0.0575,0.04832,0.03278,0.00406,0.05075,-0.00805,0.02095,0.0088,-0.05191,0.0317,-0.00666,-0.0035,0.01164,0.04492,-0.01184,0.05265,-0.0212,0.00983,-0.0351,0.06918,0.00078,-0.07248,0.01117,0.07225,0.00252,0.04816,0.12445,0.00541,0.04979,0.03217,-0.00563,-0.01062,0.0672,-0.0386,-0.06781,0.0359,-0.02944,0.06579,0.00536,-0.0271,-0.02777,-0.0349,-0.03809,-0.00355,0.06049,0.03877,-0.02448,0.07789,0.03401,0.08713,0.05802,-0.03777,-0.00173,-0.01247,0.03953,0.03139,0.01831,0.04832,0.03481,-0.09513,0.06083,0.03315,0.03655,0.0313,-0.05489,-0.02758,-0.06172,0.06432,-0.02356,0.04507,0.03773,0.01232,-0.02166,-0.00594,-0.0316,-0.02758,0.00189,-0.01824,-0.00888,0.03489,0.01132,0.07632,-0.03976,-0.00885,0.05653,0.01113,0.00052,0.01464,0.06094,0.01056,0.00981,-0.02436,-0.01374,0.00756,-0.02922,0.0007,-0.02989,-0.01343,-0.01566,0.01219,0.09499,-0.00334,-0.04667,0.0397,0.01369,0.02459,-0.03276,-0.05889,0.01188,0.02177,-0.04665,0.01634,-0.01808,0.02757,0.00663,0.0015,0.03934,-0.00647,0.01883,0.03798,-0.05073,-0.00412,-0.01119,0.00998,0.01712,0.06119,-0.03072,-0.05092,0.03236,-0.0437,-0.07533,0.00345,0.02418,0.03161,0.00241,-0.04821,-0.03469,-0.01226,-0.00298,0.0408,-0.03537,0.03911,-0.03714,0.02377,-0.06461,-0.0093,-0.0395,-0.02381,0.0416,-0.00049,-0.02434,0.0222,-0.06394,-0.01821,0.03549,0.00144,0.01091,-0.04317,-0.05358,-0.06283,-0.02332,0.02127,0.023,0.0208,-0.06731,-0.00035,-0.00614,0.00102,0.04983,-0.03247,0.07129,-0.01918,0.02532,-0.02772,0.00618,0.04524,0.00223,0.01506,-0.00104,-0.00658,-0.04111,-0.05135,-0.03496,-0.04144,0.04214,0.0221,-0.00988,0.03613,-0.0173,0.05011,0.02918,-0.03653,-0.00194,-0.00762,0.02611,-0.03535,-0.08728,0.03569,0.04725,-0.01761,-0.01733,-0.02032,0.02604,0.01378,-0.00204,0.01048,0.01635,0.01462,-0.05583,-0.06849,-0.00818,0.0038,-0.01441,0.04318,0.0638,-0.00193,0.02472,0.01677,0.06493,0.02142,-0.01438,-0.02039,0.00597,0.00783,0.00789,0.02382,-0.04485,0.0166,0.01485,-0.00335,-0.02856,0.01035,0.00622,0.03521,-0.03294,-0.00452,0.04117,0.01282,-0.00252,0.0186,0.00728,0.03007,-0.00538,-0.01873,0.02181,0.02968,-0.04411,-0.04193,-0.0148,0.01853,0.04618,0.0649,0.00316,-0.01709,0.03601,-0.0197,-0.063,-0.01787,-0.00983,-0.02932,-0.01311,0.09572,-0.01799,-0.01375,-0.03856,0.04755,0.04166,0.05823,0.06681,-0.00238,-0.01226,0.02328,-0.02754,0.02246,-0.02905,-0.03173,0.01788,-0.01604,0.04688,-0.03583,0.03863,0.02425,0.01032,0.03304,0.03434,0.00191,0.02718,-0.02083,-0.04603,-0.02085,0.06897,0.0456,0.00179,0.01275,-0.06282,0.0355,0.05005,-0.04439,-0.03777,0.00284,0.01878,0.00263,-0.006,0.04506,0.03179,0.077,0.00036,0.00274,-0.05342,0.00366,-0.01975,-0.04075,-0.02137,-0.00212,0.00837,-0.02442,-0.01515,-0.01959,-0.0228,0.00473,0.0038,-0.00924,0.03118,0.01934,0.0042,0.04358,0.01814,0.01493,-0.04005,-0.00621,-0.01756,0.01473,0.02609,0.00063,-0.05718,0.00053,-0.007,-0.00438,0.04475,0.04139,0.0274,-0.06732,-0.03079,-0.02695,-0.00331,-0.00208,-0.04247,0.02673,0.00991,0.02782,0.00505,-0.02457,-0.01184,-0.00495,-0.00661,0.02614,-0.06166,-0.07935,6e-05,-0.00771,-0.04099,0.05548,-0.00551,0.04284,0.01158,-0.00368,-0.05819,0.0345,-0.0408,0.00808,0.05957,0.00159,-0.07722,0.0348,0.00896,0.00204,0.03091,0.03338,-0.03222,0.02767,0.05444,0.02435,0.02457,0.01041,0.04995,0.02365,0.08436,-0.03284,-0.03227,0.00015,0.06076,0.06467,0.06404,-0.02678,-0.06657,0.00336,0.01129,0.04571,-0.02942,0.00863,-0.00084,-0.0113,0.03495,-0.01306,0.04023,0.05525,-0.05898,-0.04648,-0.03741,0.00556,0.11101,0.0312,-0.00505,-0.06961,0.02541,-0.02195,0.00875,0.00156,0.00458,0.0427,-0.05329,0.02858,-0.0269,0.04836,0.07836,0.02361,0.03397,-0.03525,0.01606,0.0074,0.02281,-0.03688,-0.0302,0.00704,0.0408,-0.02671,0.00199,0.03906,0.0283,-0.03741,-0.01298,-0.03308,-0.01268,-0.00134,0.01846,-0.00241,-0.04286,-0.00379,-0.01958,0.03116,0.00759,0.00144,0.03463,0.04883,-0.02147,0.02175,0.0248,0.01914,3e-05,-0.03423,-0.0098,0.02712,0.01132,0.04247,0.00537,0.04082,0.00955,-0.00847,-0.04303,0.03069,-0.04931,0.02507,-0.12063,-0.03283,0.02674,-0.05597,-0.02064,-0.00322,0.04042,-0.00595,-0.0722,-0.00661,0.0379,-0.06378,0.0385,-0.0197,-0.05645,0.00823,0.02778,-0.04653,-0.00267,0.00758,-0.04892,0.04749,-0.01557,0.0285,0.02867,-0.0357,0.00116,-0.02601,-0.01834,-0.04695,0.06105,0.05069,0.01877,-0.03226,0.0202,0.00236,0.02022,0.0441,-0.00395,0.01886,0.01947,-0.03249,-0.0471,0.02148,-0.01725,-0.00254,-0.05253,0.01274,-0.04336,0.00854,-0.02471,-0.02073,-0.01272,0.01984,0.00355,0.05197,-0.00531,0.02836,-0.00968,-0.02959,0.00652,0.01502,0.03077,-0.00641,-0.08939,-0.00513,-0.00799,-0.01372,-0.01895,0.0219,0.00445,-0.03563,0.00214,0.01337,-0.03918,-0.0445,0.03013,-0.03884,-0.00294,-0.01435,-0.03421,-0.00112,-0.0566,-0.03359,-0.0319,0.00877,0.00083,0.00343,0.01372,-0.0296,-0.026

Dot Matrix Printer is an example for impact printers.\nNon-Impact Printers - Non-impact printers do not physically strike the page. These printers\nprint a complete page at a time, thus they are also called as Page Printers. Laser printers\nand Inkjet printers are laid on this type of printers.\nMemory Devices\nA memory is used to store data and instructions. Computer memory is the storage space\nin the computer system, where data is to be processed and instructions required for\nprocessing are stored. The memory is divided into large number of small parts called cells.\nEach location or cell has a unique address.\nMemory is classified into three types -\n1. Cache Memory - Cache memory is a very high speed semiconductor memory which\ncan speed up the CPU.

facilities in the education system. The computer\nprovides a tool in the education system known as CBE (Computer Based Education). CBE\ninvolves control, delivery, and evaluation of learning as follows.\n1) Simulations:\nComputer simulators and prototypes can be used to perform the rather impossible\nexperiments on the subjects which seemed impossible to be done in the labs especially in\nthe field of medicine and engineering.\n2) Distance Learning and E- Learning:\nThis is the trend in 21st century education where the obstacles arise due to distance are\nbeing eliminated. One can attend classes and access learning materials remotely, without\nhaving to travel to the learning center.\n3) Better Content Delivery:\nThe motivation effect that comes about due to embracing ICT in teaching and learning is a\ncommon factor. For instance, multimedia and interactive content on interactive boards\nremain quite engaging and motivating making students pay more attention in class.\n4) Individualized

houses and fisheries industries. ICT is\nused to control light, moisture and air inside the greenhouses. Robotic machines are used\nto monitor plant growth levels, record them and harvesting in large scale farm lands. Crop\nharvesting and seedling planter robotics are also useful to keep efficiency of agriculture\nindustry. Automatic weed removers and insect control devices protect the crop from weed\nplants and insects respectively. Monitoring devices are used to monitor factors affect crop\nproduction such as weather, climatic changes, rainfall, wind direction, soil fertility and\nwater content.\nRadio Frequency Identification Device (RFID) helps in identifying and counting the number\nof animals in farmhouses.

computer containing\nthousands of vacuum tubes that utilized punch cards and switches to input data\nand punch cards to output and store data.\n2nd Generation Computers (1956 – 1963)\nIn this generation, transistors were used as the fundamental building block.\nIBM 1620, IBM 7094, CDC 1604, CDC 3600, UNIVAC 1108 were some computers\ndeveloped in this generation.\n3rd Generation Computers (1964 – 1975)\nThe computers of third generation used Integrated Circuits (ICs) in place of transistors. A\nsingle IC contains many transistors, resistors, and capacitors along with the associated\ncircuitry.\nIBM-360 series, PDP (Personal Data Processor), TDC-316 were the computers of

Dot matrix printer\nIt uses a print head that moves back-and-forth, or in an up-and-down motion, on the\npage and prints by striking an ink ribbon against the paper, much like the print\nmechanism on a typewriter.\n2. Inkjet printer\nIn the inkjet printing mechanism, the print head has several tiny nozzles, also called\njets.

Magnetic tape\nMagnetic tape is one of the oldest technologies for electronic data storage on a\nmagnetic surface. Tape has largely been displaced as a primary and backup storage\nmedium, but it remains well-suited for archiving because of its high capacity, low cost\nand long durability.

it\ncan be repeatedly read, written to, and erased. DVD-RAM discs can be\nrewritten 100 times more than a DVD-RW.\n5. Flash drive\n6. Memory card\nFlash drives and memory cards use Electrically Erasable Programmable Read Only\nMemory (EEPROM) technology to store data on one or more semiconductor chips.\nParallel computing\nParallel computing is a type of computation in which many programs or processes are\ndone simultaneously. Large problems can often be divided into smaller ones, which can\nthen be solved at the same time.\nIn simple terms, parallel computing is breaking up a task into smaller pieces and executing\nthose pieces at the same time, each on their own processor or on a set of computers that\nhave been networked together.\nThe following example displays the difference between single processor and

executions.\n65","vector":[-0.00729,0.02378,-0.18078,-0.02232,0.01969,-0.05616,0.02162,-0.03362,0.00671,-0.04535,-0.03763,0.0048,0.08823,0.03817,-0.03177,-0.04964,-0.00092,-0.01694,-0.03128,0.00112,0.00974,-0.0305,0.00605,-0.03174,0.02095,0.05753,-0.0018,-0.06755,-0.01893,-0.01637,0.00638,0.04643,0.01892,-0.06299,-0.01766,-0.08259,0.02598,-0.01331,-0.03361,-0.00151,-0.03448,-0.02611,0.03938,-0.07483,0.02933,-0.01204,0.04313,0.0633,0.00908,-0.07114,0.03228,-0.04568,-0.01095,-0.01372,0.05745,0.03781,0.00811,0.10466,0.04175,-0.01547,0.12897,0.09678,-0.04632,0.08193,0.02266,-0.0037,-0.0074,0.05065,-0.04343,-0.01042,0.00746,-0.01255,0.05841,0.02515,-0.04057,0.0397,-0.03252,-0.02072,-0.00199,0.03708,0.05092,0.00467,0.07238,0.02684,0.0269,0.01301,-0.02072,0.01721,-0.02456,0.09421,-0.01637,0.04917,-0.00642,0.01962,-0.10475,0.04941,-0.02645,0.00799,-0.02502,-0.07247,-0.03188,-0.02242,0.06206,-0.01343,0.04677,-0.0024,-0.0019,-0.01305,0.01718,0.0044,0.00924,0.05887,-0.04505,0.02086,0.03757,0.0283,0.10372,-0.04266,0.02217,0.08584,0.02143,-0.03972,-0.00035,0.04448,0.00984,0.07525,-0.02832,0.00238,-0.02649,-0.04054,-0.00298,-0.03011,-0.05094,0.02783,-0.01365,0.04734,-0.03151,-0.03696,0.03998,0.00851,0.02414,-0.00689,-0.02526,-0.00486,-0.0222,-0.01593,0.02202,-0.04334,-0.04151,0.03713,0.00233,0.01868,0.00423,-0.00818,-0.00023,-0.01349,-0.02064,-0.00965,0.06723,0.03946,0.07135,-0.0215,-0.03951,0.03975,-0.02531,-0.04014,0.04618,0.02763,0.01624,0.01195,-0.04856,-0.01652,-0.02391,-0.01293,0.01669,-0.00607,0.04858,-0.01599,0.03712,-0.0434,0.01596,-0.03725,0.01846,0.00259,-0.01015,-0.04721,0.02018,-0.02317,-0.05034,-0.02531,-0.00131,0.05255,-0.00264,-0.0631,-0.07094,-0.0502,0.03282,-0.00413,0.00805,-0.05846,0.01755,-0.00963,-0.03653,0.04465,0.01284,0.03696,0.00199,0.02474,-0.03336,0.02282,0.0668,0.00596,0.00085,0.0231,0.0282,-0.00433,-0.03503,-0.03397,-0.01627,0.03615,0.02551,-0.04956,0.00127,-0.01296,0.03562,0.00264,-0.03792,0.00999,-0.02603,0.01811,0.01452,-0.06458,0.00397,0.02677,0.04314,0.03088,0.01112,0.03268,0.03506,0.03983,0.02547,0.02894,0.03738,-0.04045,-0.04421,0.01688,0.01921,-0.06276,-0.00857,0.05954,0.00478,-0.03146,0.00603,0.00795,0.01126,-0.07408,0.00218,0.01415,0.0041,-0.01539,0.0353,0.00118,0.06565,-0.01255,0.00124,-0.07532,-0.01453,0.03703,0.02739,-0.00498,0.00476,-0.00818,0.01629,0.03837,-0.0104,-0.01234,0.03659,-0.01261,0.01771,0.04391,0.01062,-0.0792,-0.02977,-0.02471,-0.00865,0.0521,0.04786,0.04233,-0.0157,0.01752,0.00796,-0.03359,-0.01423,0.05192,-0.02191,-0.01081,0.05698,-0.00109,-0.02533,-0.02555,-0.01445,0.03043,0.0479,0.0264,-0.01243,-0.01809,0.00761,-0.02669,-0.02364,0.01247,-0.04629,0.00692,-0.02099,0.03492,-0.01447,0.05178,0.00715,0.00089,0.04491,-0.00725,0.0021,-0.0263,-0.02555,-0.05404,-0.0074,0.11509,-0.00783,-0.00818,-0.00805,-0.00435,-0.00142,0.03844,-0.01251,-0.0194,0.02,-0.02431,-0.02473,-0.00428,-0.00895,0.02739,0.05216,0.0314,0.01149,-0.06485,-0.00512,0.00195,-0.02763,-0.02593,-0.00579,0.005,-0.01279,0.01497,-0.01938,0.02226,0.0004,-0.01992,0.02947,0.02803,-0.03578,0.0277,0.00339,0.04152,-0.00653,-0.02266,-0.01721,0.01858,0.03245,0.02849,0.02774,-0.03575,0.02191,0.00071,0.03567,0.05526,0.01329,0.01169,-0.07666,0.01645,-0.01795,-0.02189,0.00187,-0.03382,-0.00285,0.00133,0.0155,-0.02799,0.01908,0.00373,-0.01784,-0.01217,-0.00027,-0.05553,-0.04427,0.01785,0.01886,-0.00162,0.01081,0.01865,0.04814,0.02021,-0.02433,-0.08358,0.02901,-0.03809,0.01781,0.04755,-0.04732,-0.08928,0.01173,-0.00874,0.04708,0.02892,0.00681,-0.0237,0.02139,-0.00456,0.04664,0.05081,-0.04981,0.02357,0.03297,0.06854,-0.00307,-0.01436,0.00776,0.04519,0.03852,0.04142,0.01426,-0.08135,0.012,0.04305,0.05801,-0.03436,0.00608,-0.04605,-0.01018,0.01787,0.00527,0.03992,-0.0108,-0.06256,-0.03325,0.01713,0.0028,0.11016,0.0128,-0.04689,-0.07316,0.01074,0.03855,0.04298,0.01826,0.00749,0.06226,-0.03142,0.01658,0.03773,0.04531,0.04236,-0.01165,0.00587,-0.0443,0.01604,-0.01871,0.01358,0.00255,0.00891,0.00089,0.09618,-0.02975,-0.01217,0.02329,-0.00665,-0.00881,-0.03023,-0.00823,0.01007,0.06137,0.06352,-0.01115,-0.03441,-0.06461,-0.02479,-0.03511,-0.02122,0.04254,-0.03534,0.0119,0.01149,0.01518,0.0262,0.00686,0.00827,0.00579,-0.00146,-0.01036,0.03769,0.05469,-0.02271,0.03146,0.01638,-0.02503,-0.02536,-0.00759,-0.00932,0.01473,-0.04599,-0.05174,0.02749,0.01456,0.06029,0.01345,0.05675,0.02706,-0.08105,0.01502,-0.01151,-0.04286,0.02836,-0.03776,-0.02745,0.00639,0.0002,-0.08229,0.00034,0.01438,-0.04243,0.04403,-0.02386,0.00222,-0.01649,-0.03554,-0.00777,-0.00493,-0.04428,-0.06197,0.05368,0.03502,0.04375,-0.00924,0.00363,-0.00689,-0.02186,-0.01356,-0.02013,-0.02797,0.03232,-0.00094,-0.05907,0.02014,-0.03934,0.01284,-0.05,0.00774,-0.00028,0.02502,-0.03956,-0.03426,-0.03473,0.02512,0.05846,0.07278,-0.02653,0.01376,-0.03593,-0.01216,0.01138,0.03387,0.04375,0.01958,-0.09794,0.00489,0.02101,-0.0113,-0.01748,0.01274,-0.02149,-0.09188,0.01197,0.0851,-0.03842,0.00162,0.03137,-0.02075,0.02688,-0.02873,-0.01523,0.00134,-0.04732,-0.02658,0.03467,0.00026,0.0

relatively small, and is usually embedded in\nthe processor chip (CPU).\n- Level 2 (L2) cache is often more capacity than L1. It may be located on the CPU or\non a separate.\n- Level 3 (L3) cache is typically specialized memory that works to improve the\nperformance of L1 and L2. It can be significantly slower than L1 or L2, but is usually\ndouble the speed of RAM.\nRAM (Random Access Memory)\nRAM is the main memory of the computer that holds data for running applications and\nrequired data for a computer.\nTypes of RAM\n(i) SRAM – Static RAM\nSRAM is random access memory that retains data bits in its memory as long as power\nis being supplied. SRAM is used for cache memory and register memory.\n(ii) DRAM – Dynamic RAM\nThis type of RAM is continuously refreshed or it will lose its contents.\n(iii) SDRAM - Synchronous DRAM\nIt is a type of memory that synchronizes itself with the computer's system clock.\nNon-volatile memory\nThis is a type of computer memory that has the capability to hold saved data even if the\npower is turned

Once a program has been\nwritten onto a PROM, it remains there forever.\nEPROM (Erasable PROM)\nEPROM is a special type of memory that retains its contents until it is exposed to\nultraviolet light. The ultraviolet light clears its contents, making it possible to reprogram the\nmemory.\nEEPROM (Electrically Erasable PROM)\nIT can be erased by exposing it to an electrical charge.\n71","vector":[0.04186,0.01873,-0.17747,-0.05164,0.0521,0.00739,0.04186,-0.02107,0.00689,-0.01337,-0.04752,0.03106,0.00423,0.04618,-0.03358,-0.01761,0.00428,-0.04696,-0.00931,0.03895,-0.00801,-0.04975,-0.06757,-0.01785,0.03828,0.06077,0.00297,-0.05074,-0.04838,0.00085,0.05918,-0.04919,0.05465,-0.05277,-0.0346,-0.09289,0.00108,0.00541,0.02481,0.05052,0.01793,0.01673,0.05289,-0.01268,0.0516,0.0583,0.03171,-0.01206,0.06654,-0.08807,0.08017,-0.04926,0.00829,0.00914,0.08454,-0.05587,0.03231,0.05426,0.02663,0.01591,0.09192,0.06528,-0.04788,0.06353,0.00403,-0.00995,-0.04122,0.07017,-0.05253,-0.05075,0.05693,0.01238,-0.01213,-0.02923,0.01753,0.02299,-0.001,-0.05653,0.01711,0.04709,0.02636,0.02987,0.05728,0.02798,0.06947,0.03027,-0.03289,0.02112,-0.00203,0.04191,0.02925,0.02567,0.02197,0.01482,-0.05,0.05734,0.01651,0.03716,-0.0142,-0.04796,0.00811,-0.0708,0.05382,-0.02489,0.07067,0.03962,-0.01657,0.01653,-0.01535,-0.01903,-0.02671,0.0115,-0.04614,0.03693,-0.01069,0.01228,0.07991,-0.05233,0.03003,0.05638,-0.01264,0.00382,0.02436,0.05305,-0.00889,0.01481,-0.01208,0.00539,0.01794,-0.01734,-0.03025,-0.01902,-0.01684,0.00905,0.02531,0.06996,0.0141,-0.02929,0.03619,0.02332,0.03288,-0.05175,-0.01529,-0.02612,-0.01534,-0.07367,0.03614,-0.00309,-0.01125,0.01338,0.01491,0.0293,-0.01571,-0.00332,0.03075,-0.04814,-0.02226,-0.01644,0.02558,0.04829,0.04151,0.02042,-0.0639,0.03399,-0.02808,-0.08404,0.0075,0.03439,0.0168,-0.00567,-0.05244,-0.03433,0.00897,0.00065,0.04369,-0.02441,0.03072,-0.03651,0.03581,-0.04884,-0.00038,-0.03004,0.01062,0.05413,-0.01565,-0.03154,0.007,0.02238,-0.04252,-0.01148,-0.04926,0.0113,-0.04383,-0.03478,-0.05802,-0.05732,0.01207,0.00257,0.05223,-0.03332,-0.01387,0.00979,-0.02348,0.04442,0.00568,0.03224,-0.02457,-0.00685,-0.01058,0.02077,0.09709,-0.00651,-0.00952,-0.01042,0.00583,-0.04426,-0.03576,-0.02556,-0.03692,0.02712,0.00716,0.00014,0.04586,-0.01137,-0.00159,0.02101,-0.049,0.02603,-0.01679,0.027,-0.02646,-0.11456,0.00482,0.03365,0.00254,0.01074,-0.01681,0.04772,-0.00098,0.00676,-0.00129,0.04262,0.01453,-0.04422,-0.05591,-0.00365,0.00685,-0.01858,0.031,0.03446,-0.00067,-0.01754,0.01902,0.01944,0.03556,-0.01553,-0.01593,-0.01821,0.00587,0.00867,0.03855,-0.022,0.00029,0.02525,0.04017,-0.0208,-0.03071,0.02426,0.00838,0.03157,-0.00783,0.03497,0.01181,0.02714,0.02839,-0.01297,0.01363,-0.00142,0.02711,0.02027,0.00421,-0.06107,-0.02286,-0.03224,-0.00947,0.02265,0.03711,0.01812,-0.03659,0.01628,-0.01928,-0.02686,0.02769,-0.01463,0.00759,0.04133,0.05423,-0.02562,-0.03144,-0.01282,0.02332,0.02018,0.05582,0.02628,-0.03257,-0.01577,0.0051,-0.01755,0.04822,-0.01679,-0.06361,0.0111,-0.02318,0.03798,-0.06634,0.07656,0.05437,0.02489,0.0568,-0.01214,-0.02481,-0.01325,0.02109,-0.02191,-0.00809,0.04813,0.03337,-0.00627,-0.0071,-0.02955,0.03379,0.0759,-0.01572,-0.01985,-0.02377,0.02211,-0.03268,0.02096,0.01483,-0.00139,0.09899,-0.00301,0.04629,-0.06712,-0.01817,0.01711,-0.04634,-0.05831,0.04499,0.0434,0.01567,-0.01122,-0.03361,-0.02138,-0.01272,0.00691,-0.00682,0.05025,-0.01201,0.01844,0.03197,-0.00501,0.01788,-0.07637,0.01206,-0.00179,0.03376,-0.01101,-0.00019,-0.03415,0.00321,0.02265,0.02043,0.02521,0.00605,0.01334,-0.08362,-0.03512,-0.02906,0.00398,0.01978,-0.07653,-0.00611,-0.01009,0.03032,-0.02792,0.01959,-0.01967,-0.03512,-0.01198,0.00727,-0.0117,-0.06402,0.02697,0.01011,-0.04625,0.01492,0.00381,0.03246,-0.01112,-0.03072,-0.00452,0.01733,-0.02606,0.02907,0.04686,-0.02087,-0.06617,0.0188,0.00681,0.02169,0.04438,0.03608,-0.03315,0.00577,0.03627,0.0442,0.07387,0.03329,0.0393,0.02284,0.04067,-0.04758,-0.01289,0.01205,0.03607,0.0415,0.0843,-0.01249,-0.05416,-0.0028,0.00518,0.04058,-0.00877,-0.00051,-0.03732,-0.0144,0.04951,-0.03381,0.06556,0.03679,-0.05024,-0.00579,0.01254,0.00931,0.10682,0.03028,-0.0294,-0.05465,0.03884,0.00113,0.03979,-0.00623,0.00202,0.04753,-0.02602,-0.02324,-0.0242,0.06683,0.08975,-0.04416,0.00852,-0.03845,0.04307,-0.01635,0.00041,0.02165,-0.052,0.00503,0.08551,-0.01504,-0.00138,0.0236,0.01739,-0.00566,-0.00833,-0.00755,-0.03355,-0.00665,0.04753,-0.01455,-0.02805,-0.03943,-0.00336,-0.00384,0.02169,-0.00785,0.00015,0.01925,0.01889,0.05034,0.05492,0.00329,-0.00235,-0.00624,-0.04492,-0.04479,0.02002,0.02036,0.01661,0.05294,0.02116,0.00306,-0.03211,0.03324,-0.03479,0.03869,-0.04598,-0.0706,-0.01683,-0.01769,0.01756,-0.04587,0.05304,-0.00063,-0.04513,-0.01232,0.00043,-0.0178,0.03447,-0.03657,-0.01085,0.01913,0.01212,-0.06546,-0.02004,0.00662,-0.05191,0.05926,0.00834,0.04888,-0.01166,-0.04895,0.00306,-0.02215,-0.06563,-0.05828,0.05898,0.02001,0.06168,-0.03327,-0.00647,0.00418,0.06835,0.01155,-0.00638,-0.02988,0.03096,0.00331,-0.10483,0.01173,-0.04496,0.00039,-0.03159,0.01056,-0.0431,0.01109,-0.01453,-0.036,0.00584,-0.00428,-0.0266,0.0635,0.02048,0.00965,-0.02764,-0.00272,-0.0346,-0.00877,0.02172,0.01243,-0.05471,0.01511,0.01457,0.01128,-0.05702,-0.00386,-0.0061,-0.05573,-0.03469,-0.01669,-0.03037,0.06139,0.02434,-0.04091,-0.01449,0.01677,-0.04959,0.00391,-0.03818,-0.02997,0.01318,-0.01296,0.00057,

Magnetic storage device\nMagnetic storage is the manipulation of magnetic fields on a medium in order to\nrecord audio, video or other data. In main computer storage mechanisms have\ngenerally involved a spinning disc or platter and read write heads on an armature.\nMany types of magnetic storage involve a tape medium ether on a real or in a cassette that\nis moved by read and write heads.\nEg: Hard disk, Floppy disk, Magnetic tape\n2. Optical storage device\nOptical storage is any storage method in which data is written and read with a laser\nfor archival or backup purposes. Typically, data is written to optical media, such as\nCDs and DVDs. For several years, proponents have spoken of optical storage as a\nnear-future replacement for both hard drives in personal computers and tape\nbackup in mass storage. Optical media is more durable than tape and less\nvulnerable to environmental conditions.

Solid state storage\nSolid-state storage (SSS) is a type of computer storage media made from silicon\nmicrochips. SSS stores data electronically instead of magnetically, as spinning hard\ndisk drives (HDDs) or magnetic oxide tape do. Solid-state storage can be found in\nthree form factors: solid-state drives (SSD), solid-state cards (SSC) and solid-state\nmodules (SSM). An important advantage of solid-state storage is that it contains no\nmechanical parts, allowing data transfer to and from storage media to take place at\na much higher speed and providing a more predictable lifespan for the storage\nmedia. Because there are no moving parts, SSDs produce far less heat than HDDs.\nEg: Flash drive, Memory card\nMemory Access method\n(i) Sequential access\nStart at the beginning and read through in

3...) and (-1,-2,-3,…) are integers.\n- Neither decimal number nor fractions are integers.\nE.g. :- 0.75, 8.5\nDecimal number system\n- This number system has 10 digits of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.\n- When the value of a particular number exceeds the largest number 9 in that number\nset, the multiples of 10 of the number of values are transferred to the next (left) place\nvalue. Every place value is multiplied by ten to get the next place value.\nE.g. :- 3456 = 3 x 103 + 4 x 102 + 5 x 101 + 6 x 100\n= 3000 + 400 + 50 + 6\n= 3456\nThe place values in decimal number are multiple values of 10. Therefore the base\nvalue of the decimal number system is 10.\nBinary number system\n- The binary number system has two digits which can be represent two states.\n- These two states are, represented by digits “0” and “1”.\n- Therefore a number system with the two digits can be used here.\n- There are multiplications of 2 in place values of the binary number system. They are as\nfollows.\n24 23 22 21 20 2-1 2-2

as usual in regular binary.\nHowever, negative numbers are represented differently. To negate a number, replace all\nzeros with ones, and ones with zeros - flip the bits. Thus, 12 would be 00001100, and -12\nwould be 11110011. As in signed magnitude, the leftmost bit (most significant bit-MSB)\nindicates the sign (1 is negative, 0 is positive). To compute the value of a negative\nnumber, flip the bits and translate as before.\nWhen representing positive and negative numbers in 8-bit ones complement binary form,\nthe positive numbers are the same as in signed binary notation.\nE.g.: -120 is represented in one’s complement form as 100001112 and\n-60 is represented in one’s complement form as 110000112\nThe ones complement system still has two ways of writing 010 (000000002 = +010\nand 111111112 = −010);\nTwo’s Complement.\nA single set of bits is used.

4 5 6 7 8 9\nASCII – ASCII (American Standard Codes for Information Interchange) normally uses 8\nbits (1 byte) to store each character. However, the 8th bit is used as a check digit,\nmeaning that only 7 bits are available to store each character. This gives ASCII the ability\nto store a total of 2^7 = 128 different values . The 7 bit ASCII code was originally proposed\nby the American National Standard Institute (ANSI). (IBM personal computers use ASCII).\nEBCDIC (Extended Binary Coded Decimal Interchange Code) – The 8 bit EBCDIC is used\nprimarily by large IBM mainframe computers and compatible equipment. It uses 256\ndifferent characters\nUNICODE – The 16 bit code provides unique code points to characters in many of the\nworld’s languages including Sinhala and Tamil.

of\nvariables\n105","vector":[0.00937,0.05323,-0.15219,-0.06399,0.05664,-0.02422,0.05538,0.04331,0.0053,0.0488,-0.052,0.02416,0.10749,0.0279,-0.00625,0.00162,-0.03797,-0.06666,0.04391,-0.03645,-0.04369,0.01219,-0.02557,-0.05726,0.1007,0.00744,-0.04396,0.00231,-0.06578,0.0099,-0.01299,-0.00724,0.02107,-0.03306,-0.05943,-0.08064,0.02732,0.04119,0.04412,-0.02866,0.04035,0.01485,-0.00363,-0.02015,0.02512,-0.04789,0.05807,-0.00318,0.04945,-0.08007,-0.00079,-0.04653,0.01865,0.00892,0.02653,0.06785,0.01652,0.01139,0.08057,0.01109,0.03421,0.06698,-0.02978,0.06083,0.03628,-0.00534,0.01026,0.04438,-0.03282,0.0233,0.02252,-0.00958,0.02128,0.0043,-0.04076,-0.02251,0.00232,0.01639,0.01036,0.03371,0.00037,0.00999,0.09344,-0.01906,0.00492,-0.00027,-0.04549,-0.02046,-0.03073,0.03609,-0.01217,0.04014,0.03347,0.03221,-0.05535,0.02388,0.01419,0.00045,-0.02365,-0.04368,-0.07137,-0.01447,0.00754,-0.0281,0.00206,0.04619,0.02404,0.01006,0.01137,-0.01905,-0.05739,0.01547,-0.0696,0.01513,0.00323,-0.02181,0.02601,-0.05383,0.03782,-0.00371,0.0007,-0.04431,0.00146,0.03614,0.0239,0.05201,-0.05365,0.00999,0.03895,-0.06501,-0.01114,-0.01609,-0.0293,0.02031,0.01134,0.04509,-0.01087,-0.03993,0.00791,-0.00841,0.03021,0.01293,-0.02664,-0.00721,-0.00692,-0.06681,0.01071,-0.01793,-0.02521,-0.00564,-0.00404,0.02137,0.033,0.03063,0.01569,-0.04508,0.02484,0.01463,0.01251,-0.01277,0.08097,-0.01591,-0.02961,0.05368,-0.02592,-0.05296,0.05155,0.03612,0.01665,0.02112,-0.00707,-0.03754,0.0102,-0.00105,0.01852,-0.02233,0.0291,-0.03794,0.01541,-0.00852,0.04645,-0.03146,0.06418,0.03077,0.00376,0.0066,0.01287,-0.01719,-0.03627,-0.0367,-0.01689,0.02306,-0.10256,-0.04561,-0.06954,-0.02012,0.05618,0.00579,0.03834,-0.0519,0.00756,0.02705,-0.0213,0.01302,-0.00762,0.05521,-0.00556,0.01734,-0.01587,0.00537,0.02995,-0.02178,0.00822,-0.00024,0.00777,-0.02808,-0.00979,-0.0131,-0.01633,0.01467,-0.00811,0.00284,0.04126,0.02676,0.02338,0.02409,-0.0271,0.0247,-0.02558,0.01996,-0.05076,-0.07652,0.02167,-0.02834,0.04289,0.02199,0.03747,0.03929,0.02543,0.04858,0.01348,0.01691,-0.00419,0.01706,-0.01671,0.00509,0.07138,-0.0123,0.03282,0.07818,0.01039,0.01591,-0.01965,-0.01068,0.01929,-0.01431,-0.01165,-0.01986,0.06833,0.00983,0.03265,-0.05976,0.03473,-0.02231,-0.0729,-0.05247,-0.05511,-0.02871,0.02196,0.0115,0.00961,0.05074,0.00511,0.03108,0.01098,-0.0252,0.01101,-0.02289,-0.02782,0.0657,-0.02551,-0.03491,-0.03693,0.02012,-0.00851,0.01519,0.01281,0.00962,-0.00557,0.07135,0.00955,0.01848,-0.01843,0.04359,0.02219,0.06742,0.05693,-0.03646,0.00613,-0.01373,0.00777,0.01744,0.02208,0.03319,0.00484,-0.00921,0.00534,-0.0135,0.02478,0.01773,-0.07823,-0.03844,-0.01055,-0.02072,-0.00524,0.0337,0.02791,0.03462,0.06093,-0.02439,-0.01864,-0.05991,0.00686,-0.05037,-0.00563,0.07665,-0.01811,0.01767,-0.03794,-0.03627,0.03821,0.02505,0.00785,-0.02599,-0.01657,2e-05,-0.01383,-0.05274,-0.01621,0.05616,0.07469,-0.03413,-0.02268,-0.03574,-0.01802,-0.02717,-0.04263,0.0293,0.00851,0.0084,-0.0275,-0.00502,0.00469,0.01449,0.01799,-0.01303,0.03268,0.06769,0.01217,0.03201,0.05306,-0.00344,0.00836,-0.00189,0.01531,0.01254,0.01028,0.0293,-0.02943,-0.00281,-0.03051,0.00257,0.02063,0.05334,-0.02184,-0.01334,-0.09071,0.00155,-0.01781,0.02207,-0.01116,0.01603,0.01905,-0.01727,0.00046,0.01347,-0.01025,-0.03401,0.02751,0.0591,-0.01912,0.00401,-0.04741,0.01812,0.02853,-0.02171,-0.00696,0.01203,-0.01729,0.02477,-0.0277,-0.05557,0.02004,0.01197,-0.0337,-0.01747,0.02111,-0.05039,0.06303,0.03518,0.01293,0.02737,0.03538,-0.02458,0.01844,0.04135,0.06274,0.04424,-0.01608,0.00634,0.03168,0.08692,0.01482,0.0051,-0.01055,0.00825,-0.00951,0.05717,-0.00948,-0.04492,0.01107,0.02195,0.02942,0.0119,-0.03804,-0.01064,-0.00816,0.06499,-0.04145,0.07164,-0.00448,-0.06512,-0.04504,-0.04368,0.04891,0.08713,-0.00574,-0.05932,-0.07891,0.01831,-0.02212,0.08974,0.03758,0.02289,0.06079,-0.04964,0.01733,0.06236,0.028,0.04737,-0.02069,0.00679,-0.02669,-0.01378,0.01107,-0.03588,-0.03467,-0.02138,0.05122,0.06263,-0.05843,-0.01781,0.00685,-0.00213,-0.0489,-0.04067,0.00974,0.0106,0.00617,0.03644,-0.03579,-0.02225,-0.05159,-0.04834,-0.02433,0.07888,0.02509,-0.00117,0.00297,0.00791,0.02729,0.03289,0.00288,-0.03846,-0.05379,-0.03173,-0.00259,0.03007,0.04303,0.02626,-0.00362,0.04579,-0.00601,0.02568,-0.00107,-0.04431,-0.00265,-0.03678,-0.07615,0.0111,-0.00552,0.00301,0.02682,0.03036,0.03065,-0.07788,0.01729,-0.00026,-0.03055,0.01358,0.02587,-0.05468,-0.0136,-0.00964,-0.06035,0.00283,-0.02079,-0.05584,0.04693,-0.03553,0.01012,-0.00567,-0.03664,0.00094,0.00256,-0.04699,-0.02291,0.02233,0.01913,0.00559,0.00981,-0.00509,-0.00926,0.04255,0.02577,-0.01582,-0.00096,-0.00186,0.00074,-0.12015,-0.03807,-0.04684,-0.03295,-0.0457,0.00429,-0.08036,-0.0702,-0.02807,-0.01714,0.03531,-0.00859,0.01923,0.0524,0.02479,0.00241,-0.01782,0.00529,0.02212,0.02123,0.04336,0.00246,-0.09251,0.00135,-0.01113,-0.00495,0.01313,0.00855,-0.02138,-0.03868,-0.02764,-0.01359,-0.00099,0.03008,0.01898,-0.00357,0.02639,-0.02224,-0.01242,0.02007,-0.01901,-0.026,0.03911,0.00599,-0.0143

circuits that are capable of performing\nsimple addition with the help of logic gates.\n- Let us first take a look at the addition of single bits.\no 0+0 = 0\no 0+1 = 1\no 1+0 = 1\no 1+1 = 10\nThese are the least possible single-bit combinations. However, the result for 1+1 is 10.\nTherefore, the sum result must be re-written as a 2-bit output. Thus, the above equations\ncan be written as\n0+0 = 00\n0+1 = 01\n1+0 = 01\n1+1 = 10\nHere the output ‘1’of ‘10’ becomes the carry-out. The result is shown in a truth-table below.\n‘SUM’ is the normal output and ‘CARRY’ is\nthe carry-out.\nINPUTS OUTPUTS\nA B SUM CARRY\n0 0 0 0\n0 1 1 0\n1 0 1 0\n1 1 0 1\nFull Adder\nThe main difference between a half-adder and a full-adder is that the full-adder has three\ninputs and two outputs. The first two inputs are A and B and the third input is an input\ncarry designated as Carry In. When a full adder logic is designed we will be able to string\neight of them together to create a 8- bit adder and cascade the carry bit from one adder to\nthe next.","vector":[0.01389,0.05732,-0.16869,-0.04231,0.04474,-0.02606,0.04638,-0.01594,-0.01857,-0.01269,-0.09494,0.06419,0.04506,0.05712,0.01268,0.02777,-0.03592,-0.04722,0.06023,0.00493,-0.01212,-0.0103,-0.05721,-0.04997,0.02355,-0.02713,-0.02783,-0.01396,-0.07581,0.03972,0.0144,-0.04378,0.01119,-0.03169,-0.06545,-0.05354,0.04087,0.00601,0.01889,0.00615,0.00954,0.00093,-0.04369,-0.0032,0.02475,0.00069,0.06667,-0.00293,0.03013,-0.05176,-0.00261,-0.06412,-0.01995,0.03481,0.0537,0.04093,-0.08696,0.03908,0.08519,0.01989,0.05352,0.09338,-0.03634,0.06032,0.03635,-0.00988,0.01316,0.04144,-0.01535,0.01478,0.05442,-0.04757,0.05989,-0.00853,0.00544,-0.01657,-0.00134,-0.01331,0.04026,0.02541,-0.00494,-0.05582,0.07237,0.00992,0.04122,0.01616,-0.04952,-0.03813,-0.03388,0.06745,0.00408,0.02495,0.02941,0.01016,-0.04129,-0.01759,-0.02044,0.01739,0.00477,-0.05023,-0.01214,-0.00326,0.02479,-0.01803,-0.0066,0.0461,0.02158,0.00858,0.00749,0.01219,-0.09509,0.00031,-0.01564,-0.02152,0.00297,0.02733,0.06224,-0.02899,0.02705,-0.00755,-0.02366,-0.04007,-0.00021,0.01736,0.04393,0.04279,-0.02331,0.00613,0.02561,-0.04825,-0.02878,-0.0186,-0.03291,0.03829,0.0482,0.06479,-0.00502,-0.01392,0.01864,-0.01923,0.004,-0.01711,-0.06169,-0.01617,0.04396,-0.01107,0.02773,0.0045,-0.06863,-0.00665,0.01626,0.03545,0.01351,0.05289,0.01174,-0.04327,0.05684,-0.00558,0.00544,-0.00396,0.0706,-0.01826,-0.03193,0.06382,-0.02593,-0.00973,0.03035,0.01133,0.04611,0.02074,-0.01966,-0.04748,-0.01343,0.00045,0.05992,-0.03034,0.06263,0.01692,0.02377,-0.06756,0.01668,-0.04227,0.01645,0.04164,0.00127,-0.0577,0.06721,-0.03579,-0.03817,-0.01606,0.01603,0.06661,-0.0608,-0.00675,-0.06392,-0.03184,0.02993,-0.01987,0.0405,-0.02637,-0.03389,-0.00454,-0.0291,0.01941,-0.02366,0.09127,0.00858,0.04501,-0.02012,-0.01554,0.01656,-0.01108,-0.01072,0.03422,0.03998,-0.03656,-0.00876,-0.02414,-0.03964,-0.00651,0.02869,-0.02728,0.02213,0.01139,0.02647,0.02805,-0.0388,0.01399,-0.07114,0.01585,-0.02557,-0.0439,0.03055,-0.03597,0.02805,-0.00233,-0.00308,0.05395,0.00302,0.03776,0.02803,0.03649,0.00211,-0.02112,-0.05669,-0.01066,0.00343,0.00255,-0.00962,0.05917,-0.01799,-0.02114,0.01766,0.01285,0.01536,0.01142,-0.02579,-0.04128,0.03812,-0.00391,-0.0073,-0.02313,0.03848,0.00792,-0.07161,-0.03978,-0.00936,-0.02103,0.00014,0.00432,-0.01646,-0.01636,-0.02454,0.04143,0.02967,-0.03641,0.04184,0.01152,0.02553,0.07497,0.00257,-0.02379,-0.0625,0.00922,-0.03095,0.01503,0.0504,-0.01082,0.01526,0.04662,-0.02277,-0.00715,0.02053,-0.0241,0.05837,0.03412,0.05077,0.00011,-0.01583,-0.01504,-0.00176,-0.00385,0.05515,0.03813,-0.00473,0.00459,0.02612,-0.0091,0.02104,0.00385,-0.02943,-0.01433,0.0069,0.00821,-0.02268,0.02885,0.03916,0.03628,0.04141,-0.03736,0.02296,-0.05019,-0.01261,-0.04574,0.04789,0.05127,0.01226,0.02573,-0.05597,-0.02398,0.0604,0.0279,-0.02066,-0.0096,-0.03531,-0.02824,-0.00709,-0.01769,-0.01044,0.07061,0.02934,0.00996,0.00311,-0.0331,-0.01699,-0.04811,-0.01332,-0.00517,-0.00939,0.01601,-0.01417,0.00577,-0.03988,0.03106,0.00691,-0.02746,-0.00013,0.03884,0.0253,0.01339,0.06551,0.02856,-0.01807,-0.03668,0.03172,-0.0168,0.00582,0.03587,0.01848,-0.04361,-0.02067,0.01202,0.03685,0.06793,-0.03271,-0.00417,-0.06164,-0.02334,-0.03448,0.03223,-0.0006,0.00882,0.02147,-0.03317,0.01203,0.00172,0.00528,-0.0294,-0.00729,0.04968,-0.01008,-0.06413,-0.05514,0.00538,-0.00222,-0.02534,0.03855,-0.02832,-0.01189,0.02578,-0.04981,-0.04456,0.03278,-0.00414,-0.00359,0.02702,-0.01652,-0.0516,0.03986,-0.00639,0.00697,0.08084,-0.01281,-0.00483,0.01498,0.06394,0.08701,0.0458,-0.0122,-0.01088,0.04964,0.08338,-0.00777,0.02071,-0.0154,0.02079,-0.00871,0.03414,0.01836,-0.06892,-0.00865,0.02672,0.02137,-0.01183,-0.05546,-0.00017,-0.00845,0.06675,-0.00087,0.0322,0.06139,-0.04576,-0.05591,-0.02576,0.03319,0.11662,-0.01016,-0.08167,-0.06086,0.03959,-0.01552,0.0314,0.05158,-0.01532,0.07824,-0.01483,0.00532,0.01025,0.03428,0.05363,-0.02919,0.00827,-0.02918,0.00927,0.00547,-0.01366,0.04871,-0.053,-0.00633,0.04003,-0.01846,0.0092,0.01072,0.00644,-0.01839,-0.02062,0.02491,0.01259,-0.00563,0.03848,-0.00496,-0.05545,-0.06883,-0.01091,-0.0188,0.04459,0.03258,-0.00206,0.01591,-0.00869,0.05218,0.05699,0.01149,-0.02834,-0.08627,-0.01217,0.00513,0.04066,0.01526,-0.02023,-0.01917,0.04116,-0.01095,0.02217,0.01108,-0.04625,-0.02263,-0.04807,-0.06938,-0.02055,-0.05106,0.03367,-0.00573,-0.00335,0.04557,-0.03642,0.01613,-0.00898,-0.0439,0.04753,0.01232,-0.05352,0.00432,0.02419,-0.07105,-0.00959,-0.00874,-0.07383,0.05471,0.00708,0.0107,0.04765,-0.01612,0.01705,-0.0298,-0.03454,-0.04486,0.0125,0.04235,0.02427,-0.0012,0.00128,-0.00797,0.10357,0.02345,-0.02297,-0.00218,0.00943,-0.00738,-0.09738,-0.01834,0.00833,-0.02838,-0.02485,0.02319,-0.05402,-0.06981,-0.03525,0.00694,-0.00787,0.01756,0.05688,0.02088,-0.00447,0.00905,-0.03395,-0.0229,-0.00299,0.03693,0.0135,0.00606,-0.11175,-0.01216,-0.01493,0.00513,0.02353,0.02109,-0.02782,-0.02667,-0.02264,-0.0102,0.01408,-0.01374,0.03364,-0.00604,-0.01559,-0.04108,0.00258,0.00414,-0.00778,-0.05262,0.02737,

only on the input of that time.\nSequential Circuit: Output depends not only on the present inputs but also on the\nprevious inputs and outputs. This type of circuit is required to perform sequence of actions\nwithout getting any further inputs. Use for memory storage (SRAM)\nFlip Flops\nFlip flops are actually an application of logic gates. With the help of Boolean logic, you can\ncreate memory with them. Flip flops can also be considered as the most basic idea of a\nRandom-Access Memory. When a certain input value is given to them, they will be\nremembered.\nOne form of flip-flop acts exactly like the power switch on a computer: the first time its\ninput becomes 1, the flip flop turns on the output, and the second time its input becomes 1,\nthe flip-flop turns off the output.

Executes only one program at atime\n- Multi Task - Executes multiple programs at atime\nDifferent types of Operating Systems\n- Single user-single task– A single task is performed by one user at a time.\n- Single user-Multi task- Several programs are run at the same time by a single user.\n- Multi user-Multi task – A multi-user operating system has been designed for more than\none user to access the computer at the same or different time.\n- Multi-threading –\nA thread is also called a sub process. Threads provide a way to improve application\nperformance through the parallel execution of sub process.\n- Real Time – OS is designed to run applications with very precise timing and with a

type is to include the type as\nan extension to the file name.\nFile can be classified into various types based on the content.\n- Executable(.exe)\n- Text(.txt, .docx, …etc)\n- Image(.bmp, .png, .jpeg, …etc)\n- Video (.vob, .flv, .swf,…etc)\n- Audio (.wav, .mp3,…etc)\n- Compressed( .rar, .zip,…etc)\nDirectory and file organization\nDirectories are continues used to organize files logically.\nFile Structure\nA File Structure is a format that the operating system can understand.\n- A file has a certain defined structure according to its type.\n- A text file is a sequence of characters organized into lines.\n- An object file is a sequence of bytes organized into blocks that are understandable\nby the machine.\nFile Systems\nA file system is used to control how data is

It is the responsibility of the Operating System to create a\nprotection system which ensures that a user who is running a particular program is\nauthentic. Operating Systems generally identifies/ authenticates users using following\nthree ways:\n- Username / Password - User need to enter a registered username and password\nwith Operating system to login into the system.\n- User attribute - fingerprint/ eye retina pattern/ signature - User need to pass\nhis/her attribute via designated input device used by operating system to login into\nthe

return an error\nindication to the running process. In all cases, the operating system will provide a default\naction which may or may not be process termination.\nInterrupts\n- Interrupt is an event that alters the sequence of execution of process.\n- Interrupt can occur due to a time expiry an OS service request I/O completion.\n- For example when a disk driver has finished transferring the requested data, it\ngenerates an interrupt to the OS to inform the OS that the task is over.\n- Interrupts occur asynchronously to the ongoing activity of the processor. Thus the\ntimes at which interrupts occur are unpredictable.\nInterrupt Handling\nGenerally I/O models are slower than CPU. After each I/O call, CPU has to sit idle until\nI/O device complete the operation, and so processor saves the status of current process\nand executes some other process. When I/O operation is over, I/O devices issue an\ninterrupt to CPU then stores the original process and reserves execution.\nProcess

always ready to run, and never terminates.\nNewly created processes are created and marked as ready, and are queued to run.\nAs the single running process terminates or is interrupted, it is marked as\nReady by the operating system, and the next Ready process is commenced\n(or continued).\nHere the operating system has the role of a dispatcher: dispatching work for the processor\naccording to

After each I/O call, CPU has to sit idle until\nI/O device complete the operation, and so processor saves the status of current\nprocess and executes some other process. When I/O operation is over, I/O devices\nissue an interrupt to CPU then stores the original process and reserves execution.\nContext Switching\n- A context switch is the mechanism to store and restore the state or context of a\nCPU in Process Control block so that a process execution can be resumed from the\nsame point at a later time.\n- Using this technique a context switcher enables multiple processes to share a\nsingle CPU. Context switching is an essential part of a multitasking

the system for processing. Job scheduler selects processes from\nthe queue and loads them into memory for execution. Process loads into the\nmemory for CPU scheduling.\n- Medium-term scheduling: Medium term scheduling is in charge of swapping\nprocesses between the main memory and the secondary storage.\n- Short-term scheduling (low-level scheduling): Determines which ready\nprocess will be assigned the CPU when it next becomes available.\nLong-term scheduling (Job scheduling)\n- Determines which processes are admitted to the system for processing\n- Controls the degree of multiprogramming\n- If more processes are admitted\n- better CPU usage\n- less likely that all processes will be

It tracks\nwhenever some memory gets freed or unallocated and correspondingly it updates the\nstatus.\nAn Operating System does the following activities for memory management:\n- Keeps tracks of primary memory, i.e., what part of it are in use by whom, what part are\nnot in use.\n- In multiprogramming, the OS decides which process will get memory when andhow\nmuch.\n140","vector":[0.03973,0.00571,-0.1595,-0.03039,0.04284,-0.02909,0.05285,0.01665,0.02844,-0.0282,-0.04413,0.00689,0.07084,0.06317,-0.01961,-0.05327,-0.0249,-0.04755,-0.0211,0.02102,0.00999,-0.01446,-0.03038,0.01641,0.05812,0.07957,0.00815,-0.04884,-0.01103,0.04837,0.04832,0.01318,0.01843,-0.06956,-0.03632,-0.11797,0.03015,-0.01061,0.02782,-0.01784,-0.03901,-0.01697,0.02065,-0.02946,0.0441,0.01168,0.00039,-0.02997,0.06564,-0.03223,0.04603,-0.02286,-0.05066,0.04446,0.08487,-0.01548,-0.01028,0.067,0.03075,-0.04093,0.13783,0.06054,-0.05202,0.08226,0.00233,-0.01771,-0.02579,0.04738,-0.05803,-0.00966,0.03754,-0.03241,0.01278,-0.02696,-0.0157,0.01972,-0.01401,-0.01274,0.01241,0.02846,0.05404,0.00813,0.09423,0.01697,0.03792,0.04557,-0.04806,0.0212,-0.04154,0.07738,-0.01443,0.02791,0.03244,0.0239,-0.07711,0.02212,-0.00047,0.01457,-0.01888,-0.0663,-0.03185,-0.03508,0.02472,-0.01799,0.07881,0.05425,0.02354,0.05292,0.00639,0.024,-0.02168,0.00954,-0.02198,0.04833,0.0093,0.01398,0.08886,-0.03749,0.01604,0.07036,-0.02431,-0.01885,0.04262,0.0394,0.01597,0.03013,-0.01763,-0.01757,-0.00241,0.01583,-0.02191,-0.02761,-0.02072,-0.01847,0.03743,0.0746,-0.03505,-0.02238,0.01022,-0.00399,0.04366,-0.02346,-0.01089,-0.0008,-0.0041,-0.05166,0.0502,0.01365,-0.01961,0.01179,-0.00644,0.02663,-0.03267,0.0246,0.02478,-0.02889,-0.06141,0.01397,0.03989,0.02306,0.07094,-0.00468,0.01143,0.03085,-0.03495,-0.07123,0.03208,0.02231,0.02955,-0.01415,-0.03747,-0.03105,-0.00426,-0.0085,0.01185,-0.00309,0.03559,-0.02833,0.07556,-0.05658,0.01316,-0.04028,0.02336,0.03033,-0.02325,-0.03546,0.00559,-0.03515,-0.05689,-0.00458,-0.01381,0.02653,-0.00435,-0.0253,-0.06386,-0.04637,0.00946,-0.01374,0.03628,-0.04435,0.01058,-0.01073,-0.0396,0.05381,-0.01112,0.05287,-0.02638,0.02904,-0.0424,0.01997,0.0669,0.01502,-0.02237,-0.00966,0.00319,-0.00648,-0.01526,-0.01123,-0.00833,0.0198,-0.02927,-0.02239,0.03858,0.01577,0.03179,0.00558,-0.04392,0.00233,-0.04661,0.03978,-0.01742,-0.09835,0.03697,0.03024,0.04453,0.02836,-0.00677,0.05441,0.04927,0.06746,-0.00939,0.03181,0.00178,-0.03872,-0.05543,-0.00075,0.05639,-0.02402,-0.01182,0.04259,-0.0146,0.0146,0.04437,0.0172,0.04928,-0.04616,0.00482,-0.00056,-0.00465,0.01071,0.01365,-0.03772,0.02964,-0.01733,0.02173,-0.06216,-0.02922,0.01464,-0.01386,-0.00637,-0.01114,0.03577,0.01034,0.05852,0.00716,0.0047,0.04509,-0.01905,0.03718,0.01258,-0.01468,-0.04074,-0.03642,-0.02349,0.01385,0.04095,0.0203,0.03577,-0.02119,0.00558,0.0231,-0.01788,0.00438,-0.00257,0.00276,0.03228,0.0764,0.00469,-0.01485,-0.0338,0.01565,0.01096,0.01309,0.04273,-0.02923,0.01,0.00504,4e-05,-0.01511,0.01521,-0.01997,-0.00785,-0.0473,0.00618,-0.03495,0.03834,0.01284,0.01051,0.04825,-0.02419,-0.01932,-0.0407,-0.03002,-0.03833,-0.0013,0.05607,0.01558,-0.00474,-0.0225,0.01732,0.04455,0.06442,-0.05366,-0.03164,-0.0198,-0.01901,0.02717,-0.01205,0.03635,0.00196,0.07384,0.00338,0.04193,-0.04237,-0.01955,-0.01577,-0.02604,-0.0176,0.02028,0.02804,0.01043,-0.01576,-0.04641,-0.01542,-0.00522,-0.02944,-0.01378,0.06403,-0.01835,0.00557,0.01946,0.01008,-0.03107,-0.03638,0.03295,0.0216,0.03945,0.00448,0.01633,-0.02788,-0.03655,-0.03121,-0.01222,0.03459,-0.00084,-0.00745,-0.06644,-0.00823,-0.01385,7e-05,0.02574,-0.01588,-0.01459,0.00392,0.00356,-0.02007,0.00883,-0.01227,0.0056,0.01982,0.00524,-0.07164,-0.05627,0.00951,0.03876,-0.00247,0.04785,0.0492,0.03745,0.01584,-0.05749,-0.03142,-0.00116,-0.02462,-0.00588,0.05104,-0.00648,-0.06986,-0.00621,-0.00746,0.04256,0.03931,-0.01137,-0.03312,0.00014,0.00505,0.02073,0.07598,-0.02302,0.02271,0.03991,0.06838,-0.02132,0.01951,0.00608,0.05984,0.02802,0.06336,0.00195,-0.09636,-0.02103,0.00083,0.0621,0.02623,-0.02077,-0.00081,0.01055,0.0219,-0.00674,0.02158,0.01158,-0.03986,-0.05051,0.0017,-0.02499,0.07387,0.04732,-0.01644,-0.06358,0.00199,-0.00376,0.02978,-0.00274,-0.01746,0.05078,-0.02453,0.00806,0.01609,0.0196,0.03722,-0.01274,0.01608,-0.01561,0.02002,-0.02122,-0.02136,0.03064,-0.00501,-0.00284,0.09897,0.01777,-0.02545,0.01097,0.00192,-0.00746,0.00378,-0.02846,-0.00637,0.07302,0.0447,-0.02403,-0.01969,-0.01931,-0.01951,-0.03921,0.0159,0.01157,-0.03162,0.00474,0.0126,0.04099,0.07291,-0.00224,0.00089,-0.02676,-0.05551,-0.06411,0.03499,0.01672,-0.01647,0.04701,0.03211,-0.01577,-0.00916,0.0018,-0.03691,0.0287,-0.03887,-0.06381,0.02205,0.01971,0.04873,-0.03089,0.04456,0.0164,-0.09326,0.01182,1e-05,-0.02296,0.03764,-0.01599,-0.00105,0.02724,-0.02308,-0.08054,-0.02763,-0.0118,-0.03948,0.07451,0.01094,0.03138,-0.03192,-0.01538,0.01599,-0.01815,-0.02776,-0.04306,0.0339,0.05367,0.05022,-0.02544,-0.00381,-0.01603,0.05777,0.01803,-0.03361,-0.02834,0.01666,0.02487,-0.10528,0.01343,0.00046,0.00314,-0.02926,0.03067,-0.03522,-0.00976,-0.02173,-0.03938,-0.00075,0.01272,0.01679,0.0528,-0.00911,0.04619,-0.06648,0.01991,0.02716,0.02282,0.04575,0.00045,-0.06533,-0.00638,0.01609,0.01736,0.00831,-0.03355,0.02376,-0.06094,-0.04697,0.03768,-0.0285,0.02396,0.02251,-0.01915,0.04025,-0.00738,-0.03668,0.03498,-0.00413,-0.01881,0.00919,-0.01696,0.0023

address.\n142","vector":[0.01142,0.03196,-0.16784,-0.03648,0.03794,-0.02193,0.00183,0.00859,0.02536,-0.01616,-0.02307,0.02102,0.05077,0.02004,-0.00534,-0.02314,-0.00174,-0.02826,-0.04314,-0.0073,-0.03244,-0.02574,-0.03281,-0.02318,0.06051,0.05523,0.0353,-0.01893,-0.02091,0.03069,0.10424,-0.03297,0.03826,-0.07484,-0.02932,-0.0931,-0.01329,0.02711,-0.00169,-0.01179,-0.05112,-0.01483,-0.00292,-0.01379,0.0581,0.0417,-0.00218,-0.06896,0.09024,-0.04766,0.04852,-0.05859,0.01309,0.00715,0.11273,-0.01347,-0.00178,0.03619,0.01924,0.00106,0.12066,0.07987,-0.057,0.05738,0.03311,-0.00103,-0.02758,0.05507,-0.04861,-0.0053,0.05558,-0.00112,0.04822,-0.00762,-0.0109,-0.01143,-0.044,-0.041,0.02941,0.03022,0.04286,0.01625,0.10452,-0.00913,0.05461,0.02488,-0.01105,0.02102,-0.01194,0.07924,-0.01759,0.0303,0.02566,0.03328,-0.07565,0.00765,-0.00485,0.0507,-0.01989,-0.02118,-0.00576,-0.01607,0.06029,-0.01651,0.0584,0.0568,0.01176,0.05001,0.01708,0.03019,-0.04202,0.01716,-0.02488,0.00908,0.00465,-0.00098,0.08252,-0.0592,0.0131,0.06021,-0.02446,-0.01781,-0.00383,0.0354,0.00013,-0.00294,-0.02026,-0.01824,0.03799,0.01166,-0.02456,-0.01782,-0.03894,-0.02476,0.0354,0.04084,-0.00951,-0.02592,0.01235,0.01893,0.02791,-0.0269,-0.03586,-0.05156,-0.00248,-0.05672,0.02473,-0.03356,-0.02755,-0.00319,-0.00962,0.06178,-0.02162,-0.0006,0.03476,-0.03277,-0.03389,-0.02984,0.05467,0.04794,0.04812,-0.00564,-0.05521,0.04502,-0.00971,-0.0908,0.0455,0.02707,0.02775,-0.0035,-0.01316,-0.05338,0.02127,0.00803,0.01487,-0.01719,0.03277,-0.01935,0.03048,-0.04549,0.01563,-0.07547,0.04338,0.03325,-0.03066,-0.03595,-0.01522,0.01921,-0.04493,-0.00598,-0.03384,0.05935,-0.03349,-0.03026,-0.05924,-0.04029,0.02281,0.01144,0.01183,-0.01538,-0.00817,-0.00049,-0.02272,0.03919,-0.00889,0.03408,-0.02235,0.0189,-0.03703,0.02744,0.08099,-0.01692,-0.04625,-0.00589,0.00138,-0.01589,-0.02076,-0.01313,-0.05144,0.03962,-0.02743,-0.02069,0.04282,-0.01359,0.01035,-0.0187,-0.00607,0.00496,-0.00521,0.02921,-0.01052,-0.08579,0.04359,0.01974,-0.00053,0.02356,-0.0275,0.08774,0.00731,0.04326,0.07837,0.02788,0.01282,-0.02193,-0.0348,0.01017,0.03545,-0.04476,0.02778,0.03431,-0.03015,0.00513,0.01178,0.00178,0.03378,-0.0428,0.00696,-0.03801,0.0002,0.0179,0.0415,-0.07182,0.05529,0.00691,0.01637,-0.02128,-0.05235,0.04228,0.00202,0.02048,0.00799,0.04993,0.00397,0.05835,0.00581,-0.02174,0.0366,0.00884,0.01895,0.0318,-0.05528,-0.00515,-0.04339,-0.05444,0.00908,0.00418,0.01622,0.02263,-0.00184,0.01755,0.02262,-0.02908,-0.00354,0.0144,0.01754,0.02102,0.08949,0.00586,0.02049,-0.03267,0.02937,0.00915,-0.00268,-0.00474,-0.04817,-0.01348,0.0449,0.01494,-0.0191,-0.00588,-0.01261,0.00019,-0.01747,-0.00349,-0.05277,0.0435,0.00229,0.02389,0.02376,-0.00779,0.00402,-0.02713,-0.0227,-0.0373,-0.00107,0.05397,-0.01459,0.01056,-0.00509,0.01112,0.02545,0.02728,-0.03256,-0.02455,-0.07333,0.00672,-0.05148,0.04284,0.00388,-0.0162,0.09195,-0.01165,0.0248,-0.01945,-0.00389,0.01327,-0.03833,-0.01035,0.01735,0.01202,-0.03444,0.01431,-0.03256,-0.0055,0.0185,0.00447,-0.00569,0.04616,-0.03416,0.005,0.04102,0.00548,0.00447,-0.04602,0.00754,0.0319,0.05162,0.02349,0.01315,-0.00667,-0.03441,-0.0225,-0.02125,0.03348,-0.0016,-0.00572,-0.08691,-0.00924,-0.02869,0.0073,0.00932,-0.01894,-0.0341,-0.01512,0.00707,-0.04067,0.00243,-0.01501,0.02461,-0.01687,-0.02486,-0.08041,-0.06099,0.00186,0.02184,-0.03839,0.00182,0.00701,0.03731,0.0177,-0.05395,-0.02145,0.01509,-0.01667,-0.00243,0.03539,0.01195,-0.06767,0.01605,-0.00299,0.03262,0.02452,-0.00444,-0.06039,0.02198,0.03086,0.03349,0.07395,-0.00106,0.0267,0.03431,0.05332,0.01486,0.02324,0.03574,0.02694,0.01869,0.06142,0.0133,-0.06567,0.00233,0.0311,0.04417,-0.00454,-0.00426,-0.0107,-0.01559,-0.00222,-0.00247,0.03142,0.00747,-0.07139,-0.0257,0.00171,-0.00975,0.08416,0.04154,-0.0273,-0.06967,0.03589,0.00697,0.00057,0.02812,-0.02585,0.0814,-0.00828,0.00586,0.00228,0.05783,0.03172,0.03074,0.03414,-0.05127,0.04031,0.01076,-0.01745,0.01364,-0.01115,-0.00132,0.1263,0.01526,-0.00402,0.00349,0.00196,0.08029,0.00668,-0.05174,-0.04779,0.0546,0.00804,-0.0311,-0.02948,-0.01363,-0.0443,-0.03215,0.03782,0.00103,0.01288,0.01525,0.04778,0.0569,0.0534,-0.0101,0.01087,0.01175,-0.03401,-0.01415,0.04334,0.01267,-0.0226,0.07754,0.01632,0.00282,0.00883,0.0054,-0.00881,0.04402,-0.05165,-0.06964,-0.01743,0.01554,-0.00912,0.00196,0.00726,0.0253,-0.08716,0.01817,-0.00909,-0.02259,0.01784,-0.00629,-0.03573,-0.00134,-0.00711,-0.09696,0.01777,0.05743,-0.04112,0.07926,0.037,0.04051,-0.00894,-0.03237,0.01279,-0.03721,-0.02712,-0.05289,0.02808,0.05834,0.03448,-0.05614,-0.02915,0.00847,0.04509,0.02473,-0.01693,0.00125,0.01468,-0.00726,-0.08245,0.01292,-0.01965,0.00578,-0.03513,0.05499,-0.04571,-0.00268,-0.01882,-0.02775,-0.01749,0.01717,0.05365,0.00468,-0.01231,0.04697,-0.05908,0.03565,-0.00792,0.0394,-0.01677,-0.0297,-0.04322,0.02979,-0.00501,-0.02398,0.01406,-0.03461,-0.00175,-0.06404,-0.03454,0.03822,-0.08106,0.00763,0.03575,-0.02828,-0.00504,-0.00702,-0.06969,0.0041,-0.05005,-0.02455,0.03754,0.01104,-0.02816,0.00066,

up.\n143","vector":[0.01609,0.04186,-0.1607,-0.05279,0.02126,-0.00793,0.04642,0.01938,0.00309,-0.02692,-0.02853,0.01896,0.06823,0.02803,0.04651,-0.02743,-0.03224,-0.06625,0.00059,-0.00673,-0.01443,-0.00368,-0.03964,0.02287,0.0564,0.05176,-0.04229,-0.06373,-0.04303,0.01588,0.02866,-0.02492,0.00594,-0.09152,-0.06812,-0.08006,0.01623,-0.02056,0.04854,0.02788,-0.02556,-0.02543,0.06079,-0.09455,0.04371,-0.00588,0.03359,-0.03338,0.07754,-0.05903,0.01507,-0.04365,-0.06588,-0.02403,0.05923,-0.05272,0.03979,0.09558,-0.02151,0.00721,0.08409,0.10471,-0.05059,0.03993,0.02987,-0.01041,0.01247,0.03756,-0.05177,0.00583,0.05302,-0.03242,0.02468,-0.02354,-0.02338,0.01838,-0.02125,-0.02558,0.01244,0.0312,0.0411,0.0115,0.05564,0.04564,0.0525,0.04531,-0.04908,-0.00611,-0.01526,0.09682,-0.00271,0.04718,0.02547,0.03108,-0.08445,0.00273,4e-05,0.02101,-0.00271,-0.03995,-0.04086,-0.03511,0.03064,-0.00406,0.0634,0.05108,-0.00054,0.01031,0.01912,-0.00011,-0.00921,0.02628,-0.03945,0.00624,0.0366,0.00548,0.08374,-0.02316,-0.00566,0.0242,3e-05,-0.01394,-0.00725,0.04564,0.04456,0.04132,-0.05,-0.00691,0.00201,-0.02122,-0.0164,-0.05696,-0.03855,-0.01094,0.0323,0.02665,-0.06094,-0.04611,0.0527,-0.01548,0.02302,0.02378,-0.04404,-0.01609,0.0408,-0.0059,0.02414,-0.00974,-0.01861,0.00727,-0.03506,0.06511,-0.05964,-0.00082,-0.00081,-0.03115,0.01353,-0.03043,0.04981,0.03721,0.04487,-0.04069,-0.02501,0.04006,-0.037,-0.04189,0.01639,0.03697,0.00911,0.03181,-0.07534,-0.04142,0.00763,-0.00402,0.00445,-0.00079,0.07832,-0.05867,-0.01427,-0.03886,0.02071,-0.04425,0.03129,0.01233,-0.01571,-0.02088,-0.00995,-0.03087,-0.04145,-0.0192,-0.0167,0.0299,0.00603,-0.03604,-0.06205,-0.07872,0.05227,0.00467,0.06466,-0.03874,-0.02598,-0.02997,-0.01385,0.04493,-0.01182,0.01485,-0.01951,0.05664,-0.0165,0.05071,0.07565,0.00586,-0.00252,-0.01704,0.04402,-0.01711,-0.00455,0.03327,-0.03508,7e-05,0.02173,-0.03705,0.02235,0.00983,0.03109,-0.03592,-0.0509,0.02309,-0.06151,0.03853,-0.04415,-0.11141,0.03492,0.0015,0.01187,-0.01775,-0.00131,0.03833,0.01914,0.01977,0.0269,0.04867,-0.01852,-0.04877,-0.06301,0.02119,0.03684,-0.02203,-0.00029,0.0204,-0.0196,0.00352,0.04321,0.02112,0.04505,-0.02137,-0.02306,0.00119,0.01493,-0.02277,0.04546,-0.03205,0.05665,-0.02835,0.00222,-0.03857,-0.02071,-0.00421,0.00526,0.01926,-0.00734,-0.02306,-0.02571,0.00497,0.02794,-0.019,0.01245,0.00247,0.00575,0.03858,-0.04219,-0.05847,-0.02056,0.02098,-0.00389,0.01206,0.05943,0.02293,-0.03722,0.00688,0.03269,-0.00357,-0.04067,0.00676,0.03107,0.0373,0.09038,0.01709,0.01169,-0.00126,-0.02378,0.00498,0.03676,0.0119,-0.00012,-0.02001,0.00985,-0.04585,-0.00987,0.0223,-0.01303,0.0115,-0.00602,0.03315,-0.01867,0.03879,0.03307,0.00367,0.04059,-0.01621,-0.0081,-0.04083,-0.05812,-0.05779,-0.01954,0.0678,0.00358,0.01931,0.00775,0.0138,0.00178,0.00905,-0.03721,-0.05668,0.00767,0.02366,-0.04594,-0.00918,0.02762,0.03948,0.04534,-0.00444,0.03086,-0.02934,-0.03622,0.00983,-0.01857,-0.01624,0.03009,0.02815,0.01527,0.01573,-0.01392,0.00448,-0.02212,-0.02088,-0.02178,0.0318,-0.02158,0.02484,0.02112,0.007,-0.0177,-0.02511,0.03327,-0.0317,0.02483,0.05854,-0.02352,-0.04391,-0.03777,-0.03265,-0.00042,0.0329,0.00393,-0.0252,-0.07842,-0.00083,0.00746,0.02861,0.01127,-0.03114,-0.01162,0.022,0.03403,-0.00692,0.02576,-0.0165,0.00625,0.00853,-0.00078,-0.04884,-0.03402,-0.01596,0.04671,-0.00046,-0.01555,0.03505,0.03543,0.04127,-0.04645,-0.07057,0.06573,-0.02467,0.00672,0.02958,0.01437,-0.03579,0.01836,0.00196,0.0065,0.03375,-0.00316,-0.01414,-0.01897,0.02479,0.08117,0.04645,-0.03094,0.00816,0.02284,0.07831,-0.00853,-0.02641,-0.03098,0.02802,0.02288,0.04235,-0.01438,-0.10247,-0.05187,0.02846,0.04324,0.0237,-0.00101,-0.00882,0.02133,0.00729,-0.02657,0.05571,0.04172,-0.04185,-0.04368,0.03625,0.03106,0.07451,0.0353,-0.05574,-0.07262,0.03954,0.00664,0.00233,0.02706,0.00479,0.07149,-0.02592,0.00412,-0.0082,0.02856,-0.00305,-0.02616,-0.00636,-0.0094,0.00961,-0.01585,-0.01845,0.02492,-0.04317,0.01202,0.12271,-0.01428,0.00829,0.06087,0.01858,0.03672,0.00657,-0.02644,0.03879,0.0375,0.05637,0.01245,-0.04424,-0.05487,-0.0561,-0.03316,0.02222,0.01407,0.01989,0.01773,0.05896,0.03427,0.03843,0.00917,0.01035,-0.02123,-0.01925,-0.01544,-0.00453,0.00216,-0.01355,0.03557,0.02946,0.01824,-0.00684,0.00917,-0.04331,0.04866,-0.01797,-0.04147,0.02918,0.01776,0.0423,0.00855,0.04133,-0.00119,-0.11459,0.01178,-0.04196,-0.03751,0.04394,0.0024,-0.00073,-0.04126,0.01949,-0.09933,0.02444,-0.02179,-0.00106,0.05954,-0.02969,0.05447,0.02158,0.0074,0.00251,-0.01628,-0.03584,-0.04714,0.04281,0.04009,0.04716,-0.06044,0.01796,-0.00672,0.0096,-0.01494,-0.01624,-0.0116,0.02959,-0.01517,-0.10054,0.02221,-0.01732,0.00319,-0.0302,-0.01486,-0.04062,0.02793,-0.03798,-0.02084,-0.00919,0.01575,0.04706,0.0739,0.02176,0.05259,-0.03703,0.01988,0.02529,-0.0069,0.0867,-0.00262,-0.07553,-0.01154,0.00769,0.00216,0.00115,-0.00469,0.04239,-0.07578,-0.02872,0.01864,-0.04425,0.03558,0.06099,-0.04507,0.02079,-0.02345,-0.01982,0.0524,-0.02663,-0.00953,0.01476,-0.01933,-0.02903,-0.009,0.00467,

that they use specific\nvalues to represent any information. In digital signal, only two values are used\nto represent something i-e: 1 and 0 (binary values).\nProperties of signals\nAmplitude : The height of the wave measured in meters\nFrequency : The number of complete waves that pass a point in one\nSecond, Measured in Hertz (Hz)\nWavelength : The distance between adjacent crests, measured in meters\nPhase : phase is a position of a point in time (instant) on\na waveform cycle.\n- Propagation speed in a media\nThe speed at which a wave propagates through a given medium .The propagation\nspeed also varies from medium to medium depending on the

12 Teacher's Guide","heading":"Competency Level 6.2 – Explores signal transmission media","page":161,"text":"Reading Material\n- Wires – A wire is the physical medium used to transfer data from one network\ndevice to another. Wires are often called guided media because they guide the data\ntransfer data from one point to another without altering the frequencies, data\nimpairment are therefore reduced. Examples of guided media include Twisted pair\n(UTP and STP), Coaxial Cables, Fiber Optic Cables etc.\n- Free space – (wireless transmission or unguided media): signals are spread in to\nthe atmosphere (air), data can spread to any direction. Examples for wireless\ncommunication include radio transmission, satellite transmission etc.\nSignal Properties\no Latency: Network Latency is an expression of how much time it takes for\na unit of data to travel from one point to another.

1 bits are used to represent data and remain\nconstant during a bit interval.\no Non-return to Zero Inverted (NRZ-I): in this encoding scheme, in which a\n“1\" is represented by a transition of the physical level, while a \"0\" has no\ntransition.\no Manchester encoding: in Manchester encoding voltage changes from low\nto high\nor high to low in the middle of the signal.\n- Error Control: During data transmission, sometimes data bits may get flipped\ndue to various reasons. In such situations the data bit received is in error.\nError detection is the process of identifying that the data bit has been\naltered during transmission.

network\ninterface of a communicating device. MAC addresses are 48 bits long and are\ndivided in to 6 blocks separated by colons. Each block is 8 bits long and is further\ndivided in to two 4 bit blocks. Each four bit address is converted to hexadecimal\nnumber and a typical Mac address would look like 4A:8F:3C:4F:9E:3D. When\ndevices send and receive data over a network, MAC addresses enable the unique\nidentification of the device interface and the correct delivery of the data to the\nreceivers interface.\n- Frames: When data is generated at the source to be sent to the receiver over the\ncommunication link, at the Data link layer, data are encapsulated in to the Frame,\nwhere the data is inserted in to the frame and the MAC addresses of the sending\ndevice and the MAC address of the adjacent node are included in the header of the\nframe. Each frame is made depending on the quality of the link connecting ea pair\nof devices.","vector":[0.00198,0.05329,-0.16888,-0.05043,0.08202,0.00416,0.03519,0.0241,0.00271,-0.02837,-0.04278,0.01876,0.04384,0.02946,0.01772,-0.05951,-0.05175,-0.01572,0.05334,0.04289,-0.02299,0.0007,-0.04378,-0.02559,0.0343,-0.00211,-0.00037,-0.00916,-0.04568,-0.00127,0.05024,-0.03907,0.03259,-0.0429,-0.07218,-0.05234,0.04515,0.00508,-0.02408,0.04809,0.00492,-0.04432,-0.03105,0.02357,0.04305,0.07618,-0.00967,0.00311,0.10127,-0.05748,0.00177,0.01769,0.00316,0.02447,0.06364,0.02765,-0.02039,0.02555,0.0171,0.02905,0.10031,0.06698,-0.06373,0.05705,0.05885,0.04094,-0.02188,0.04022,-0.03353,-0.01955,0.04088,-0.03027,0.05376,0.02796,0.01411,-0.03347,-0.01754,-0.06085,0.00492,0.0632,0.0274,-0.01329,0.09813,-0.02723,0.06289,0.03394,-0.02824,0.00707,-0.01249,0.07453,-0.00961,0.00522,0.03104,0.06373,-0.08124,0.03034,-0.00902,0.05683,-0.0437,-0.05427,-0.01972,-0.01627,0.02522,-0.00861,0.06207,0.0738,0.01377,0.05289,-0.01948,-0.00201,-0.06762,0.02862,-0.04104,0.04463,-0.05481,-0.02924,0.07521,-0.0272,0.05453,0.02703,-0.02685,-0.06577,0.00178,0.0171,0.02473,-0.0201,0.02745,0.00687,0.00609,0.01017,-0.01046,-0.00578,-0.01463,-0.01151,0.03504,0.01868,-0.00942,-0.05084,0.02129,0.02886,0.01804,0.01192,-0.03068,-0.07318,0.01628,-0.08612,0.0366,-0.04266,-0.00172,0.01009,0.02826,0.02873,-0.02543,0.01578,-0.01147,-0.01963,-0.01117,-0.02852,0.01589,0.07402,0.04075,-0.02612,-0.03074,0.05308,-0.05411,-0.0678,-0.02017,0.02512,0.07709,0.01957,-0.01325,-0.00721,-0.01338,0.00331,-0.0144,-0.02341,0.0345,-0.05905,0.03976,-0.03678,0.02343,-0.05983,0.02113,-0.01331,-0.00985,0.0026,-0.0078,-0.06858,-0.04284,-0.02059,-0.04082,0.01233,-0.06448,-0.00505,-0.01282,-0.03739,0.03793,0.03022,0.06146,-0.01223,-0.01311,0.04759,-0.06204,0.09269,-0.0417,0.0409,-0.01466,0.04834,-0.00539,0.02502,0.0405,-0.0339,-0.02623,0.01348,-0.00679,0.01527,-0.00355,-0.02513,-0.03804,0.02319,0.04494,-0.00692,0.05309,-0.03847,0.06111,0.00022,-0.01709,0.00068,-0.0248,0.05688,-0.02115,-0.05382,0.04875,0.01975,-0.00549,0.02536,0.00468,0.0276,-0.03079,0.0078,0.00294,0.02277,-0.01142,-0.03131,-0.06806,-0.02357,0.00615,-0.03604,-0.00122,0.05596,0.01229,0.00279,0.01533,-0.0084,0.05105,-0.0512,0.00803,-0.01047,-0.03738,-0.00904,-0.02318,-0.05883,0.04763,-0.02588,-0.05255,-0.05438,0.00023,0.01442,0.00217,-0.00758,-0.0259,0.03534,0.03484,0.02244,0.01166,-0.04977,-0.00541,0.01245,-0.03325,0.0253,-0.02817,-0.00027,-0.05777,0.00224,0.00571,0.0145,0.01213,0.03342,-0.00553,-0.01977,0.00028,0.00791,-0.0038,0.0017,0.00732,0.01545,0.06278,0.01973,-0.01126,-0.04657,-0.01628,0.06375,0.05512,-0.00895,-0.01744,0.01285,0.00876,-0.00863,-0.02136,-0.02809,-0.05364,0.02093,-0.00907,-0.0051,-0.06862,0.03084,0.04963,0.00128,0.02572,0.03685,0.02488,-0.04331,0.00273,-0.05388,0.05767,0.07277,0.02285,0.03275,-0.01937,-0.00316,0.00219,0.01474,-0.0377,-0.01104,-0.05914,0.00993,-0.04802,0.01471,0.02024,0.02115,0.09218,0.00687,-0.02143,-0.04855,-0.0055,-0.00135,-0.02799,-0.08468,0.03409,0.00595,-0.03625,-0.00931,-0.00247,-0.00595,-0.00506,-0.00593,0.00975,0.02561,-0.02585,0.03532,0.05786,0.03405,0.04592,-0.01765,0.03477,-0.00187,0.00781,0.03023,-0.01331,-0.02601,-0.004,-0.003,0.01352,0.00297,-0.02342,-0.00794,-0.07744,-0.03773,0.00674,0.00272,-0.05132,-0.0055,-0.03219,-0.0042,0.01747,-0.04113,0.02289,-0.03984,0.01344,0.01244,-0.02892,-0.08108,-0.07251,-0.00157,0.00551,0.0045,0.03287,0.01939,0.00318,0.05092,-0.00734,-0.02848,0.02054,-0.03201,0.01283,0.1047,-0.00674,-0.08527,0.07322,0.01097,0.00703,0.04702,0.06038,-0.08943,0.04573,-0.00258,0.02958,0.01797,-0.00506,0.01868,0.02291,0.06269,0.0177,-0.00585,-0.00096,0.09108,0.0262,0.03539,-0.00782,-0.01142,-0.01175,0.0168,0.00625,0.00803,-0.03011,-0.00378,-0.00453,-0.01166,0.03909,0.03564,0.03172,-0.03453,-0.00438,-0.04707,0.02781,0.08056,0.03031,-0.00669,-0.07635,0.07987,0.02271,-0.00682,0.02887,-0.02221,0.04845,-0.01283,0.01818,-0.02419,0.05393,0.00421,-0.03103,0.03876,-0.03445,0.05259,-0.02762,-0.02424,0.03396,-0.0542,-0.0205,0.0948,-0.04881,-0.01157,0.01477,0.01229,0.03688,0.02489,-0.01982,-0.03786,0.00196,0.03159,0.00385,-0.01111,-0.03553,-0.02251,-0.01691,0.05829,-0.02787,0.01361,9e-05,-0.0103,0.03853,-0.00323,-0.03476,0.0081,-0.04721,-0.05143,-0.03984,0.01721,0.03367,-0.00591,0.03557,0.01618,0.00736,0.04388,0.01908,0.0096,0.00024,-0.04337,-0.02532,-0.00362,-0.02382,-0.02163,-0.04585,0.00627,-0.01102,-0.04536,0.01377,0.03317,-0.01765,0.02771,0.00855,-0.02647,0.00374,0.02073,-0.06811,-0.02782,0.01984,-0.02536,0.05466,-0.04081,0.0542,0.04364,-0.05955,-0.03718,-0.0165,-0.00149,-0.00421,0.0263,0.0353,0.03412,-0.02328,-0.01252,0.03985,-0.02602,0.05177,-0.03154,0.03882,-0.0045,0.00908,-0.08799,0.02666,-0.02994,0.02852,-0.01075,0.09314,-0.02628,-0.02192,-0.01812,0.02027,-0.03656,0.03344,0.04096,0.04268,0.0052,0.00527,-0.02608,-0.02718,-0.00781,-0.00302,0.01707,-0.01022,-0.08198,-0.01539,-0.02156,0.01553,0.01285,0.02822,0.00433,-0.0414,-0.02219,0.02205,0.02084,-0.008,-0.00613,-0.00637,-0.00578,-0.05922,0.00731,0.01662,-0.0307,-0.0023,0.01191,0.02661,-0.01934,0

problem of depletion of\nnetwork address of a 32 bit addressing scheme. In sub-netting each physical network\nis assigned 32-bit address mask, which is used to identify networks among other\nnetworks. All machines in the subnet should have the same subnet mask.\n- Classless Inter Domain Routing (CDIR): instead of full class A, B or C networks,\norganizations can be allocated any number of addresses using this scheme. This\nscheme can help reducing the growth of the router tables.\n- The vanishing IP address space: IPv4 has only 2^32 addresses.\nWith the ever-increasing demand for public IP addresses for Internet accesses, Internet\nwould run out of available IP addresses.

Rather than a network administrator manually assigning\nan IP address to each arriving host, the DHCP will assign IP addresses automatically.\n- Finding path to the Destination: When data leaves the source towards the\ndestination, it needs to be routed through a series of networking devices to reach\nthe destination. Routers take care of the job of routing the data from the source to\ndestinations. Routing is the process of finding an efficient path from a source to a\ngiven destination through the network.

packets.\n157","vector":[-0.02181,0.03566,-0.18849,-0.0401,0.08597,-0.03494,0.02953,0.01353,0.00809,-0.03521,-0.05429,0.00407,0.06133,0.02251,-0.02709,-0.0657,-0.05284,-0.03338,-0.00324,0.00712,-0.03965,-0.03354,0.00558,-0.02272,0.01267,-0.00589,-0.03799,-0.06845,-0.08067,-0.04021,0.02386,-0.04347,0.04714,-0.04469,-0.08628,-0.0953,0.01134,0.00115,0.00413,0.01909,0.02298,-0.00671,-0.00594,-0.06087,0.0279,-0.00302,0.0788,0.00372,0.05615,-0.05472,0.00286,-0.00942,-0.01493,0.01336,0.06853,0.03189,-0.0338,0.07062,0.02558,-0.0397,0.0709,0.07789,-0.0577,0.06037,0.05126,-0.00512,-0.06166,0.06643,-0.06319,-0.00109,0.05576,-0.02995,0.07391,0.03266,0.00683,0.01705,-0.01882,-0.02835,0.00655,0.07722,0.03158,-0.00507,0.04685,0.00778,0.02216,0.0603,-0.01094,-0.00326,-0.04388,0.08714,0.02423,0.00273,0.04144,0.00659,-0.08899,0.03262,-0.02496,0.00796,-0.02133,-0.07509,-0.04927,-0.02491,0.03152,-0.00215,0.02868,0.05011,0.00995,0.01064,0.02394,-0.00794,-0.04535,0.01516,-0.03798,0.05452,0.00818,0.00874,0.05366,-0.02799,0.04398,0.04826,0.03682,-0.04697,0.00842,0.05762,0.05775,0.04286,0.00561,0.00077,0.00078,-0.01642,-0.00575,-0.00241,-0.03554,-0.00013,-0.01185,0.05002,-0.01596,-0.01592,0.03546,0.02852,0.05338,-0.01651,-0.01391,-0.05525,0.00554,-0.06243,0.03195,-0.04547,-0.03219,0.01001,0.03122,0.02035,-0.01226,0.00575,-0.00057,-0.02283,0.01237,-0.04389,0.06692,0.00412,0.07188,-0.00561,-0.07053,0.04202,-0.04426,-0.02791,0.03087,-0.00108,0.03928,0.03247,-0.03676,-0.01654,-0.00212,0.02888,0.0293,-0.02369,0.04596,-0.03112,0.0287,-0.02458,0.01829,-0.01084,0.02892,0.00992,0.02667,0.01236,-0.03169,-0.07692,-0.0471,-0.03022,-0.01139,0.03915,-0.04814,-0.03665,-0.01012,-0.06814,0.02296,-0.00262,0.04432,-0.01752,-0.02311,0.00268,-0.04159,0.05012,-0.03894,0.06528,-0.0351,0.04631,-0.01847,0.02532,0.07616,-0.03999,-0.01975,-0.01859,-0.02786,0.00216,0.00896,-0.01714,-0.03964,0.01088,0.03513,-0.05855,0.03319,-0.00711,0.00925,-0.0221,-0.05168,-0.02479,-0.03122,0.04544,-0.00975,-0.09518,-0.01075,0.01695,0.0193,0.01819,-4e-05,0.04135,0.0009,0.01363,0.02292,0.01958,-0.0096,-0.00999,-0.07604,0.00752,0.01312,-0.03941,-0.00989,0.0588,0.03682,-0.009,0.02142,0.03507,0.00314,-0.04224,0.01849,0.04191,0.02846,-0.01454,-0.00445,-0.03135,0.03229,-0.01596,-0.04169,-0.07347,-0.00399,-0.0005,-0.00974,-0.01868,-0.02897,0.00356,0.03847,0.04128,0.00481,-0.01106,0.01467,0.01966,-0.02915,0.0639,0.00582,-0.02854,-0.04202,-0.03575,1e-05,-0.00182,0.05557,0.04117,-0.01003,0.04341,-0.00976,-0.06203,0.00321,-0.01927,0.02671,-0.00285,0.07345,-0.00819,-0.02623,-0.06828,-0.00442,0.04056,0.06566,0.03221,-0.00589,0.01857,-0.01316,0.00072,0.02291,0.01714,-0.04725,0.02477,-0.02428,0.00997,-0.01587,0.04067,0.03934,0.06594,0.05532,0.00823,-0.01011,-0.02025,-0.01472,-0.04721,0.04089,0.08098,-0.00249,-0.00331,0.01238,-0.03006,-0.00905,0.00167,-0.02866,-0.0258,-0.02431,-0.03358,-0.01252,0.00626,0.00825,0.03532,0.08621,-0.03693,-0.01023,-0.04037,-0.00198,0.00301,-0.03246,-0.02202,0.01549,0.00601,-0.0228,0.0273,-0.04782,-0.00202,-0.00953,-0.03032,-0.00964,0.04117,0.00076,0.03195,0.03035,0.02232,-0.01223,-0.01728,-0.01144,0.02342,0.03296,-0.00053,0.03827,-3e-05,-0.00774,-0.01446,-0.02623,0.0227,0.00271,0.00734,-0.06789,-0.01557,-0.03978,0.00456,-0.00469,0.00526,0.00777,0.00752,0.03625,-0.00964,-0.00549,-0.04872,-0.02669,0.01694,0.0006,-0.04083,-0.05,-0.0139,0.01992,0.01158,0.02036,0.03851,0.02736,0.06361,-0.05241,-0.05973,0.01003,-0.03621,0.00312,0.02778,-0.03753,-0.05567,0.03913,0.01713,0.03006,0.06109,-0.00359,-0.05113,0.00458,0.03389,0.05334,-0.01484,-0.02934,0.00054,0.01241,0.05037,0.00549,0.0162,0.02681,0.06481,0.06371,0.04451,0.01419,-0.05648,-0.0106,0.01828,0.02701,-0.02519,-0.05448,-0.02523,0.01137,0.03173,0.02621,0.06294,0.00182,-0.04189,-0.03168,-0.01183,0.02367,0.09835,-0.0057,-0.02383,-0.07444,0.02565,-0.00858,0.01409,0.04375,0.00285,0.05105,-0.02324,0.0393,-0.0045,0.02983,0.03723,-0.0254,0.0232,-0.04117,0.02357,-0.03281,-0.00215,0.01844,-0.00395,0.01332,0.08533,-0.02041,0.02467,0.0152,0.02361,0.0114,-0.02073,0.0057,0.01784,0.02987,0.01714,0.02656,-0.02096,-0.0543,-0.01689,-0.00254,0.03055,0.00871,-0.01051,0.04846,0.02235,0.02635,0.0247,0.00571,0.01711,-0.03216,-0.07523,-0.0251,-0.02441,0.0452,-0.00031,0.03133,0.03277,-0.00414,-0.01368,0.02204,-0.02089,0.00811,-0.04905,-0.07343,-0.02188,-0.00682,-0.01051,-0.02597,0.02934,0.02113,-0.07925,-0.0032,-0.00688,0.01722,0.08112,-0.03407,-0.00528,-0.02115,0.01708,-0.06808,0.01137,-0.02687,-0.0287,0.07755,-0.02203,0.04818,0.04396,-0.04091,0.02635,-0.01478,-0.00991,-0.0306,0.01334,0.02512,0.05777,-0.01762,-0.0185,-0.01858,0.03037,0.04861,-0.03221,-0.01442,0.01661,0.01504,-0.0653,0.02819,-0.03021,0.00511,-0.04539,0.07612,-0.07067,0.0093,-0.02495,-0.0079,-0.02075,0.03384,0.00542,0.03671,-0.00685,0.01984,-0.0306,-0.06566,0.03578,0.0256,0.02296,-0.01007,-0.09624,0.00725,0.0121,-0.03468,-0.01016,0.02045,-0.00383,-0.05027,-0.01616,0.00311,-0.02972,0.02801,0.01631,-0.01685,0.03989,-0.02863,-0.04543,0.00465,-0.0021,-0.02514,0.03438,0.00466,-0.

applications may be running on the same machine, computers\nneed something to make sure the correct software application on the destination\ncomputer gets the data packets from the source machine and some way to make\nsure replies get routed to the correct application on the source computer. Each\nprocess of a running application communicates to the underlying network through a\nspecially assigned interface called a port. Each port is assigned a unique number\ncalled port number and it is used in combination with the IP address of the device to\nidentify each process uniquely that is running on a given host. When processes\nrunning on different computers send data to the same destination, the port numbers\nof different processes and the IP addresses are used to identify the processes\ncorrectly.

Imagine your telephone, television, and Internet access going\nout when a cable company amplifier/repeater dies.\nSecurity: Unlike cable modems, each subscriber can be configured so that it will\nnot be on the same network.

They are able to perform on-the-fly configuration changes\nto compensate for any network problems or help rectify any problem that might\narise.\n- High-speed access which enables easy net surfing and fast streaming\ncontents access: ADSL is a broadband service. It offers data transmission at\nmuch greater speeds and capacity than narrowband services like ISDN and dial-\nup analog modems.

Your public IP address\ncan be found at What is my IP Address page. Private IP address, on the other\nhand, is used to assign computers within your private space without letting them\ndirectly expose to the Internet.\nFor example, if you have multiple computers within your home you may want to use\nprivate IP addresses to address each computer within your home. In this scenario,\nyour router gets the public IP address, and each of the computers, tablets and\nsmartphones connected to your router (via wired or wifi) gets a private IP address\nfrom your router via DHCP protocol.\n- Network Address Translation /Proxies\nNetwork address translation (NAT) is a method of remapping one IP address\nspace into another by modifying network address information in Internet\nProtocol (IP) datagram packet headers while they are in transit across a\ntraffic routing device. The technique was originally used for ease of rerouting traffic in\nIP networks without readdressing every host.","vector":[-0.02262,0.09445,-0.16371,-0.06101,0.0829,0.02118,-0.02282,0.0458,-0.01773,-0.04414,-0.00232,0.02641,0.00749,-0.05285,-0.02852,-0.06718,-0.03814,-0.03935,-0.01276,-0.00314,-0.03568,-0.06665,-0.0347,-0.01502,0.03388,-0.00897,0.02429,-0.05798,-0.00728,-0.05785,-0.01544,-0.06077,0.02068,-0.01222,-0.0783,-0.04458,0.00211,0.00567,-0.02938,0.01499,0.00579,-0.04388,-0.00304,-0.03542,0.01443,-0.00894,-0.0199,-0.02562,0.06405,-0.06491,0.00138,0.00131,-0.04423,-0.00163,0.08322,0.01377,-0.01076,0.01997,0.01667,0.00033,0.0932,0.08545,-0.02742,0.05428,0.05997,0.00463,-0.05546,0.06378,0.01089,0.02892,0.00674,-0.00958,0.06006,0.00989,-1e-05,-0.02401,0.01685,-0.05934,0.00413,0.07402,0.03121,-0.01264,0.07766,-0.02791,0.04692,0.05613,-0.03787,-0.00073,-0.01836,0.07571,0.00663,0.04101,0.06482,0.03399,-0.07126,0.02523,-0.01083,0.04631,-0.01642,-0.0232,-0.03436,-0.02386,0.05174,0.00152,0.03345,0.03797,-0.00057,0.02864,0.00409,0.01125,-0.01378,0.04645,-0.03881,0.02654,0.01159,-0.01367,0.08757,-0.01068,0.05527,0.06449,-0.0045,-0.02891,0.01396,0.03357,0.0261,0.02191,-0.04131,-0.01875,-0.00788,-0.01382,-0.02658,0.00121,-0.00332,0.0224,-0.00161,0.03038,-0.03351,-0.05708,0.05538,0.0363,0.04654,-0.00309,-0.03051,-0.07402,0.05298,-0.00671,0.00804,-0.0699,-0.04611,0.06243,0.03485,0.03325,0.01364,0.02013,0.01265,-0.01961,-0.01292,0.02263,0.05602,0.0516,0.05034,-0.00441,-0.05586,0.08023,-0.03456,-0.05774,0.01159,0.03808,0.00477,0.01454,-0.00631,0.00629,-0.01429,0.03164,-0.0047,-0.00363,0.02043,-0.05541,0.00315,0.01201,0.02564,-0.05655,0.0181,-0.01317,-0.00097,0.03106,-0.012,-0.06481,-0.03162,-0.01647,-0.01822,0.04792,-0.03985,-0.03097,0.01195,-0.03838,0.0273,0.02902,0.03372,-0.02929,-0.04177,0.00824,-0.03364,0.03041,-0.01817,0.04852,-0.01033,0.03828,0.02117,-4e-05,0.0481,-0.00983,-0.02961,7e-05,-0.01572,0.00541,-0.03368,-0.04674,-0.05468,-0.01785,0.01158,-0.0517,0.04168,-0.00377,0.01879,-0.01232,-0.05943,-0.01567,-0.05826,0.07663,-0.00146,-0.10438,0.02368,0.03435,0.05147,0.03979,0.02621,0.02705,-0.02097,-0.0067,0.0178,0.01073,-0.02528,0.01337,-0.06089,0.00547,-0.00029,-0.07778,-0.00253,0.03275,0.00464,0.00888,0.02155,-0.03977,0.00614,-0.02802,0.01689,0.00946,0.00108,-0.04216,-0.03344,-0.07884,0.02522,-0.03795,-0.01103,-0.02419,0.01211,0.03762,0.0142,0.0122,0.05725,0.03337,0.01683,0.01153,-0.02258,0.00044,0.02424,0.00483,-0.02087,0.05056,-0.00513,0.01268,-0.07003,-0.05157,0.02119,-0.04128,0.03462,0.00371,-0.00259,0.0038,0.05338,-0.03846,-0.01901,0.00387,0.00975,0.00822,0.04448,0.0157,0.0288,-0.04557,-0.02676,0.04477,0.0998,0.05568,0.02463,-0.00236,0.01139,-0.00459,0.00117,-0.01986,-0.0645,0.03938,-0.02425,0.04453,-0.05036,0.06129,0.04902,0.04535,0.03356,-0.00222,-0.00889,-0.04982,-0.01183,-0.03721,0.01698,0.01719,0.01413,0.03625,-0.00654,-0.0478,0.00011,0.00604,-0.036,-0.02028,-0.06662,-0.01676,0.01267,0.01913,0.01199,0.02174,0.07302,-0.07691,-0.04079,-0.02933,-0.00593,0.0024,-0.03337,-0.04778,-0.0043,0.03419,-0.02923,0.00023,-0.0382,0.02151,-0.00363,-0.04527,0.0036,0.04815,-0.0016,0.05993,0.06361,-0.00336,0.03524,-0.02723,0.00764,0.004,0.00956,0.00944,-0.01781,0.03034,-0.06699,0.00693,-0.00057,0.01116,-0.01175,0.02537,-0.08469,-0.00185,-0.03445,0.05768,-0.04482,0.00808,-0.02709,0.00648,-0.00077,-0.02205,-0.00551,-0.02208,0.01182,0.02058,-0.0135,-0.04473,-0.06133,-0.00626,0.0164,-0.01101,-0.03602,0.01088,0.01116,0.0453,-0.05609,-0.06247,0.02049,-0.01521,-0.00819,0.04561,0.0114,-0.03464,0.05943,0.01115,-0.03154,0.07944,-0.00632,-0.07331,0.02613,0.05351,0.05579,-0.00478,0.00074,0.0175,0.02624,0.05507,0.03663,-0.00737,0.02031,0.07587,0.03297,0.05435,-0.02039,-0.06628,-0.03896,0.02435,0.04934,0.01139,-0.02105,-0.00842,0.00591,0.02451,0.00341,0.01689,0.03999,-0.016,-0.02044,-0.0293,-3e-05,0.06459,0.02978,-0.01007,-0.05993,0.03074,0.05008,-0.02891,0.07734,-0.00224,0.02923,-0.00658,0.02318,-0.01318,0.04649,0.00506,-0.02045,0.06969,-0.06642,0.0279,0.03353,0.01943,0.00502,-0.05404,0.01049,0.08407,-0.00498,0.00671,0.02809,0.01421,0.04448,0.00616,0.02313,0.00119,-0.02732,0.01553,-0.02157,-0.01817,-0.02472,-0.04044,-0.01953,0.03276,-0.03377,-0.01256,-0.00271,-0.01385,0.03448,0.04358,0.00588,0.04375,-0.02836,-0.06532,-0.05445,0.02028,0.02147,-0.01846,0.05827,0.03231,0.01472,0.00319,0.01615,-0.01764,0.0303,-0.03582,-0.05883,-0.05321,0.029,-0.00645,-0.04922,0.01586,0.04375,-0.06458,0.04593,-0.01735,-0.02778,0.03376,0.0189,0.01201,0.03615,-0.00516,-0.04699,0.01467,-0.01037,0.01257,0.02814,-0.02507,0.02232,0.03165,-0.04578,-0.02763,-0.01025,0.01069,-0.07074,0.02488,0.01336,0.02822,-0.03915,0.01578,0.04989,-0.03028,0.02497,-0.03118,-0.00099,0.01271,-0.00464,-0.06125,0.07614,-0.04055,-0.00714,-0.02464,0.06418,-0.04853,-0.03324,-0.00185,0.00769,-0.03762,0.02408,0.03569,0.02736,0.02977,0.04495,-0.02362,-0.01516,0.00358,-0.00591,0.006,-0.04286,-0.03224,-0.01587,-0.01385,0.02457,0.03673,0.00247,-0.01173,-0.06733,-0.0206,0.0291,-0.01336,-0.00368,-0.00626,-0.02571,-0.01144,-0.02694,-0.03577,0.01244,-0.00643,-0.01935,0.01904,-0.02255,-0.01175,-0.00

structured methods for System Analysis & Design\n- Adopted as a standard by Central Computer and Telecommunications Agency\n(CCTA), UK\n- Covers most of the System Development Life Cycle (SDLC) from Feasibility\nStudy to System Design\n- More focus on analysis and design\nStages of the SDLC covered by SSADM\nFeasibility Study\nThe business area is analyzed to determine whether the system development is feasible\\\nRequirements Analysis\nThe requirements of the system to be developed are identified and the current business\nenvironment is modeled in terms of the processes carried out

In the problem definition, a preliminary survey of\nthe system is carried out to identify the scope of the system.\nIn the feasibility study, the proposed system is evaluated for its feasibility. Feasibility of a\nsystem means whether the development of a new or improved system is practical and\nbeneficial.\nFeasibility is evaluated from developers’ and users’ point of view. Developers see whether\nthey have the required technology and manpower to develop the new system. Is the new\nsystem really going to be beneficial to the users? Does the user have the financial ability\nto get developed that type of a system? The feasibility of the system is evaluated on the\nthree main aspects: technical, economical, operational and organizational.\nTechnical feasibility: this evaluates whether the developers have ability to construct the\nproposed system. The technical assessment helps answer the question such as whether\nthe technology needed for the system exists, how difficult system will be to develop,

analyzing the user needs to arrive at\na definition of the problem domain and system requirements. The main objective of\nrequirement analysis is to discover the boundaries of the new system and how system\nmust interact within the new problem domain. Requirement analysis helps to detect and\nresolve conflicts between (user) requirements.\n- Functional requirements: What activities that the system should carry out.\n- Describe the requested

(DFM)\nDFM is used to model data processing in the system. It is used to define partitions into sub\nsystems.

includes all the activities that make a software system available for\nuse. The general deployment process consists of several interrelated activities with\npossible transitions between them.

Direct deployment is a hardware or software\nmigration method that involves getting rid of the existing system and transferring all users\nto the new system simultaneously.\nImplementation is faster with direct deployment than other deployment methods. As the\nold system is no longer available, users cannot put off learning the new system.\nFurthermore, the complete and simultaneous implementation also avoids issues that can\narise when users are working with different software or hardware. This is the least\nexpensive migration method, assuming there are no major problems.\nOn the negative side, however, it can be hard on users to have to learn the new system\nimmediately.

Once the test\ngroup has approved the system, it can be rolled out across the organization. The testers\ncan then help train other users for the new system.

system in\nsome locations or business units or by implementing separate modules of the system\nindependently until the implementation is complete.\nBecause everything is not rolled out at once, the organization doesn’t have to deal with all\nthe potential implementation issues at the same time. Furthermore, information learned\nfrom early implementation stages can be applied to guide the rest of the process, so that\nthere are fewer issues as the implementation continues. A phased rollout also allows\nusers to adjust to the new system gradually.\nOn the other hand, it can be confusing to have groups of users working with different\nsystems or to have users working with elements of different systems.

systems are designed for both horizontal and vertical markets. In order to\ncater for the needs of many, vendors spend an enormous amount of time and effort to\nincorporate world-class functionality into their systems. Duplicating such expense to\ndevelop similar functionality in custom developed software systems, in many cases, is\nprohibitively expensive.\nCOTS software systems tend to be far more configurable than custom developed software\nsystems. In other words, they can accommodate change by adjusting parameters to a far\ngreater degree than is usual for custom developed software systems. Moreover, package\nenvironments often come with capabilities that users do not to use immediately but are\nthere for future exploitation as and when required.\nA COTS software system can be

optimization of the\nbusiness process by removing inefficiencies and bottlenecks.\nBusiness process gap analysis\nAs no COTS software solution has been specifically designed to meet any organization's\nunique requirements, there will be a gap between the business processes supported by\nthe existing systems and those supported by the COTS software system. It is imperative\nthat to understand this gap well before the implementation begins and ensure that the\norganization can accept this gap without degrading its business performance.\nBusiness process mapping\nBusiness process mapping is a group activity performed by teams of subject matter\nexperts that gather to draw step-by-step diagrams to document how business is carried\nout.

and Communication Technology, IOT – Internet of\nThings is a remarkable revision. Operations of information was exists in the Internet and now\noperations of things are handle though Internet. Such IOT area was included with practical\nactivities to the syllabus and this resource book. It was great risk because all teachers had to train\nwith practical activities. That teacher training was successfully completed by the Department of\nIT and practical activities for that unit have included in this book with explanations.\nMost of theoretical concepts have explained clearly in this book. Practical activities with\nexplanations were added to this resource book, instead of adding over loaded theoretical\ncontents.

Schematic Diagram of Blinker\nThe schematic diagram depicts an electronic circuit using symbols. Figure 10 shows the\nschematic diagram of blinker system.\nIn Figure 10, the microcontroller is supplied with power through 5V and GND (ground) pins.\nThe reset pin is connected to the ground through the reset switch. When pressed, it becomes\nlogic low and the microcontroller resets. To keep it logic high during all other time, it is usually\nconnected to positive power supply line through a resistor. XTAL1 and XTAL2 pins are\nconnected with an external oscillator. In Arduino Uno, the above components are pre-connected.\nThis makes the embedded system development easier. However, we are required to connect LED\nto be blinked with a resistor to an I/O pin.\nDesign Firmware\nFirmware means a permanent software for a hardware device.

Therefore, after assembling the\nhardware, the microcontroller is required to be programmed. The firmware development usually\nstarts with designing an algorithm using a flowchart.\nFlowchart\nUnlike programs developed for general-purpose computer systems, the firmware for an\nembedded system typically does not have any execution endpoint. This is because when the\nprogram completes its execution, there is no operating system to take control and thereby the\nprogram itself has to plan for the next step.

This number represents the amount of light intensity that falls upon the\nLDR. It is then compared with a pre-determined value and the LED is turned on/off depending\non the light intensity.

As in the previous systems,\nArduino Uno comes with most of the required components pre-connected. Only connections to\nbe made are the LM35 temperature sensor’s V+ and GND pins to 5V and ground power supply\nlines, respectively and Vout pin to an analog input pin. In addition, a digital I/O pin is required to\nbe connected to the Base (B) of a transistor via a resistor. A motor is then connected between\nCollector (C) of the transistor and separate 9V power supply line. The Emitter (E) is directly\nconnected to the common ground line. A rectifier diode is connected in parallel to the motor with\nits cathode to the 9V line. The next section discusses firmware design of Auto Fan system.\nDesign Firmware\nAs in the previous systems, the firmware development starts with designing an algorithm using a\nflowchart.\nFlowchart\nFigure 22 shows the flowcharts for the Auto Fan.\nThe flowchart of setup( ) function is shown

Schematic diagram of DoorAlarm\nFigure 26 depicts the schematic diagram of Door Alarm system. As in the previous systems,\nArduino Uno comes with most of the required components pre-connected. The additional\ncomponents to be connected are a Piezobuzzer to a digital I/O pin and a Reed switch and a 10kΩ\nresistor in series between 5V and ground lines. Reed switch and 10kΩ resistor interconnection\nare connected to a digital I/O pin.\nWhen the door is opened, as the magnetic field moves away, the Reed switch opens its contacts\nand leaves the digital I/O pin connected only to ground line through the resistor. This changes\nstate of digital I/O pin 9 logic low. As a result, the microcontroller drives the Piezo buzzer via\nthe digital I/O pin 8. The next section discusses firmware design for this purpose.\nDesign Firmware\nAs in the previous systems, the firmware development starts with designing an algorithm using a\nflowchart.\n19","vector":[-0.02538,0.04668,-0.18908,-0.0019,0.04463,-0.00918,0.0644,0.02189,0.00252,-0.04858,-0.05905,0.04235,0.03927,0.04807,0.00726,-0.01509,0.02122,-0.06175,0.00916,-0.02706,0.0174,-0.00558,-0.05886,-0.02865,0.10066,0.03131,0.03609,0.02026,-0.03443,-0.00725,0.0361,-0.04182,0.02494,-0.03673,-0.08041,-0.08603,-0.0028,0.03206,0.01619,0.0327,0.02914,-0.02237,-0.00598,-3e-05,0.02089,0.0449,0.0379,-0.03519,0.02234,-0.0335,0.02238,-0.03586,0.01437,-0.01227,0.04464,0.025,0.00794,0.02481,0.06399,-0.04803,0.04637,0.13531,-0.01083,0.07602,0.04034,0.02256,-0.00188,0.0325,-0.00068,-0.01157,0.03378,-0.0426,0.01203,-0.00356,0.02374,0.04078,-0.03623,-0.03328,-0.0016,0.03161,-0.00473,-0.02359,0.06827,0.00852,0.06093,0.02227,-0.03691,-0.02328,-0.02508,0.03546,0.01283,0.06585,-0.02766,0.0145,-0.07013,0.06044,-0.0274,0.05756,0.0151,-0.03609,-0.03716,-0.03243,0.00722,-0.0503,-0.00274,0.05906,-0.00127,-0.04543,0.00536,0.00777,-0.07611,-0.01292,-0.03954,-0.02199,0.04156,0.00277,0.08337,-0.03923,0.03438,0.02371,-0.01457,-0.04671,0.02281,0.00878,0.0161,-0.00189,-0.03365,-0.02533,0.00141,-0.00783,0.05746,-0.02804,-0.01927,-0.02902,0.04078,0.04837,-0.01189,-0.03025,0.0217,-0.00271,0.01818,0.00912,-0.02478,-0.03022,0.01674,-0.04114,0.02619,-0.02729,-0.01616,-0.00739,-0.00233,0.03308,-0.0129,0.03487,0.02134,-0.06881,0.01388,-0.02088,0.02483,0.00295,0.0521,-0.03354,-0.04574,0.0835,0.00124,-0.07634,0.00276,0.03579,0.01898,0.02392,-0.04575,-0.04237,0.00306,0.00582,0.03956,-0.01139,0.04739,-0.0257,0.05113,-0.06998,0.055,-0.01061,0.01024,0.046,-0.03078,-0.02588,0.01625,-0.03021,-0.01014,-0.0194,-0.01845,0.04102,-0.09058,-0.04193,-0.00315,-0.03276,-0.00828,0.00808,0.05579,-0.0283,-0.03878,0.01994,-0.03025,0.05251,-0.02222,0.04022,-0.01808,0.0574,0.00048,0.02292,0.02907,0.00206,0.01228,-0.00061,-0.02273,-0.03543,7e-05,-0.01988,-0.03841,0.03276,0.03704,0.00207,0.02964,0.00028,0.03412,-0.02657,-0.02081,-0.00483,-0.03628,0.01247,-0.0185,-0.0905,0.01832,-0.02698,0.00714,-0.01481,0.01759,0.04551,-0.00679,-0.01363,0.02696,0.03101,-0.00222,-0.02945,-0.04983,-0.03898,-0.0056,-0.0019,-0.00882,0.1029,0.01772,0.011,0.00168,0.02984,-0.0133,-0.04687,-0.02859,-0.04074,0.01887,-0.03352,0.04027,-0.07096,0.01504,0.00825,-0.02041,-0.01525,-0.01054,0.04328,0.01081,0.00165,0.00341,0.06755,-0.01248,0.00788,0.0119,-0.03249,0.05934,-0.02593,-0.02133,0.03327,-0.02127,-0.06596,-0.06254,-0.02363,0.01015,-0.00935,0.02467,0.00661,-0.00125,0.01507,0.00518,-0.00788,-0.04803,0.03028,-0.0031,0.01927,0.05087,0.00191,0.01183,-0.02555,0.04035,-0.02195,0.05072,-0.02727,-0.01976,-0.00693,0.01662,0.0159,0.00833,0.01383,-0.03683,0.02046,-0.01995,-0.02448,-0.05146,0.05441,0.02819,0.04868,0.03463,0.01492,-0.01818,-0.00819,-0.01998,-0.06961,0.01309,0.06229,0.03709,0.0427,0.01916,-0.01314,0.06472,0.05962,0.0128,-0.04042,-0.06928,0.01512,-0.04443,0.01703,-0.02431,0.07493,0.06231,-0.0247,0.01572,-0.04167,-0.04028,-0.01645,-0.0087,0.00982,0.01472,0.01134,-0.04239,0.0378,-0.02445,-0.002,-0.04266,-0.0004,-0.00306,0.05483,-0.00455,0.03671,0.00603,0.02234,-0.00318,-0.04955,0.0143,-0.01882,0.02101,0.00626,0.02614,-0.00491,-0.03586,-0.006,-0.03327,0.0488,0.01143,-0.00047,-0.05706,-0.06263,-0.0101,0.02664,-0.00079,0.02903,0.05504,-0.00716,0.0479,-0.01185,0.04473,-0.0185,-0.01955,-0.00903,-0.04018,-0.07666,-0.06062,0.02071,0.00463,-0.00867,0.01357,0.0186,-0.03422,0.03782,-0.04073,-0.03604,0.04235,0.01472,0.01289,0.03356,-0.00564,-0.02227,0.04442,0.0082,0.01043,0.0572,0.0156,-0.03343,0.00517,0.00775,0.05913,0.03389,-0.02954,-0.00406,0.01803,0.05324,-0.01368,-0.01947,-0.0305,0.00633,0.02017,0.0417,-0.02,-0.0781,0.02246,0.02708,0.0255,0.00105,-0.04094,-0.01603,0.02195,0.04097,-0.01312,0.05675,0.024,-0.03928,-0.02461,-0.0382,0.02677,0.11465,0.01055,-0.04825,-0.03818,0.04657,0.0183,0.04533,0.00652,0.00855,0.10844,-0.03029,0.01617,-0.0058,0.06137,0.04171,0.00987,0.00131,-0.08357,0.05621,0.00648,-0.01486,0.01846,-0.02211,0.00729,0.05674,0.00178,-0.02283,0.01238,0.01593,-0.00554,0.00299,-0.01789,0.00742,-0.00259,0.03901,-0.00303,-0.01519,-0.05064,-0.02679,-0.01343,0.02927,-0.01737,0.02073,-0.00569,-0.01376,0.06424,0.0353,0.0074,-0.03781,-0.02516,-0.01485,0.00511,0.03612,0.00666,0.00375,0.03791,0.00243,-0.02083,-0.01688,-0.00134,-0.05305,0.00523,-0.01242,-0.0386,0.00122,-0.02032,0.00645,0.01715,0.00174,-0.01192,-0.04012,0.01671,-0.02837,-0.10937,0.02778,-0.00897,-0.03599,-0.01438,-0.04384,-0.11656,0.06382,0.0371,-0.06713,0.03211,0.01593,-0.00136,0.05906,-0.01516,0.04187,0.00719,0.00377,0.00536,0.0364,0.01075,0.00612,0.05741,0.01582,0.06766,-0.01757,0.04009,0.00479,-0.01422,0.0526,-0.00992,-0.06463,0.00287,-0.0407,-0.03076,-0.00789,0.00661,-0.07446,0.00196,-0.03211,-0.03199,0.01276,0.02904,0.02299,0.04921,-0.00815,0.02164,-0.04347,-0.0311,0.00079,0.04812,0.047,0.00859,-0.05349,0.001,0.00137,-0.03805,0.0043,-0.00679,-0.02472,-0.01371,-0.00789,-0.04058,-0.03161,0.01582,0.05567,-1e-05,0.00012,-0.04301,-0.03949,0.00247,-0.02591,-0.03571,0.01673,0.04413,-0.01694,0.01288,0.04707,-0.02061,-

The whole idea is to make our life more convenient and comfortable.\nThings are everyday objects from small wristwatches to large cars and buildings. When added\ncomputing power, things become smart and are called embedded systems. Embedded systems\ncan sense the state of the physical world and change the state of the physical world. When we\nconnect the embedded systems to the Internet, they start interacting with themselves and users\nand create an Internet of Things.\nEnabling Technologies\nMany technologies have enabled the Internet of Things.

possibilities and opportunities but also to many challenges. They\ninclude social concerns such as social isolation and security and privacy concerns such as\nunauthorized control of IoT devices and access to personal and sensitive information. What if\nsomeone hacks into your smart alarm clock and then gets access to your entire network of\nthings? Therefore, it is very important to understand not just the opportunities but also the\nchallenges of IoT.\nIoT Based System Development\nIoT based systems are developed to automate the intercommunication of smart systems.\nSYSTEM5: Smart Light\nThis system explains how to turn on and off a light remotely over the Internet.

Algorithm, let us look at the problem-solving process in general. The\nproblem-solving process can be itemizedas follows:\n- Identifying the problem\n- Identifying the subproblems (causes of the main problem)\n- Finding (sub) solutions to subproblems\n- Connecting the sub-solutions logically to solve the main problem\nFor example, take a simple day to day situation of making a cup of tea. The process involves\ntaking the ingredients as input, the process of mixing the ingredients to produce the output of a\ncup of tea.\nIn some problems, it is necessary to break the big problem into small subproblems and consider\nthe solution as a collection of (sub) solutions to different subproblems.\nExample:\nMain problem: inefficient administration in an organization\nSub Problem: Problems

is called Modularization or Decomposition\nModularization means breaking a big problem into logical subproblems. In our examples, we\nbroke or modularized the big problem into small problems that cannot be further broken\nlogically. Inthe case of making a cup of tea, the modularization is boiling water, mixing the\ningredients, etc.\nIn a real-world system design, in the first attempt, we may not get the best possible\nmodularization. It is necessary to refine the initial model to make it better. In the refinement\nprocess, we may have to combine some subproblems or break into further subproblems to make\nthe system more sensible. The process can be depicted graphically as follows.\n32","vector":[0.0486,0.06439,-0.14124,-0.04685,0.03768,-0.02043,0.03378,0.00547,0.03064,-0.0387,-0.02749,-0.02306,0.06198,0.05301,-0.00755,-0.07568,-0.01148,-0.07852,-0.07324,0.01178,-0.01854,-0.0361,-0.00579,-0.04842,0.0529,0.04631,-0.02273,-0.0274,-0.05615,-0.01852,-0.00247,-0.02488,0.04089,-0.04798,-0.0748,-0.06234,0.06843,0.02384,0.00979,-0.04894,0.01544,-0.02018,0.01984,-0.07279,0.02596,-0.0037,0.06092,-0.04839,0.02531,-0.01941,0.06458,-0.06871,0.01994,-0.0087,0.04953,0.05667,-0.05591,0.05085,0.02593,-0.06092,0.08466,0.11131,-0.05936,0.07472,0.01827,-0.01309,-0.03964,0.06477,-0.05444,-0.00059,0.01503,-0.0357,0.04595,0.01903,-0.06291,0.0014,-0.01843,-0.01666,-0.00544,0.04365,0.01717,-0.02976,0.07512,0.01294,0.0393,0.00562,-0.02727,-0.0115,-0.05818,0.07521,-0.02961,0.00675,6e-05,0.00444,-0.10841,0.00832,-0.02086,0.02307,-0.008,-0.02916,-0.00835,-0.03253,-0.0415,-0.02849,0.02077,0.08782,0.02921,0.01933,-0.00459,0.00985,-0.06183,0.02662,-0.04867,0.02211,0.00954,0.01773,0.08982,-0.03398,0.00528,0.01791,-0.00585,-0.05123,-0.00264,0.00547,0.014,0.04723,0.00629,0.01368,0.02098,-0.0405,-0.01072,0.00245,-0.03387,0.00222,-0.00238,0.0832,-0.00629,-0.02495,-2e-05,-0.014,0.03571,-0.00936,-0.04673,0.00399,-0.00903,-0.03952,0.02009,0.00038,-0.06194,0.01876,-0.04105,0.03007,-0.01046,-0.02432,0.00459,-0.00611,0.0068,0.00835,0.02887,0.01549,0.03721,-0.01488,-0.05442,0.04127,-0.0232,-0.00891,-0.00893,0.0085,0.00395,-0.00988,-0.0443,-0.02676,0.01938,0.02273,0.09245,0.01078,0.05799,-0.0491,-0.01515,-0.0324,0.02921,0.00884,0.01649,0.04596,-0.01223,-0.02145,0.06472,-0.03103,-0.00547,-0.02773,0.00803,0.09095,-0.0281,-0.03415,-0.06057,-0.04899,0.02456,-0.00369,0.01572,-0.07183,0.00073,-0.00366,-0.05555,0.04331,-0.00536,0.054,-0.02009,0.0661,-0.03497,0.0233,0.04975,-0.02287,0.00239,-0.0049,-0.0196,-0.04049,0.01896,0.0187,-0.02659,0.02467,0.00759,-0.03244,-0.01148,0.02901,0.04713,-0.0131,-0.06792,0.00363,-0.04256,0.00908,0.00811,-0.05958,0.04073,0.01611,0.02312,0.02825,-0.0332,0.04013,0.04382,0.04236,-0.00817,0.03724,-0.00491,0.00743,-0.03006,0.0133,0.00792,-0.0307,-0.03283,0.05088,0.03459,-0.01447,0.00417,-0.02122,0.00021,-0.00471,-0.00631,0.02427,0.04013,0.02104,0.01943,-0.0517,0.02918,-0.01946,-0.01822,-0.0523,-0.01154,-0.00967,-0.0019,0.00584,0.0022,0.02831,0.03065,0.04278,0.00574,-0.06708,0.01586,-0.0202,0.00397,0.03857,-0.01129,-0.03974,-0.0485,-0.01572,0.00955,0.03834,0.04385,0.02493,-0.02118,0.01655,-0.00337,-0.06265,-0.01786,-0.01899,0.02213,0.03953,0.10448,-0.02588,0.00356,-0.02568,0.00975,0.019,0.06234,0.00591,-0.02857,-0.00793,0.01361,0.01955,0.01815,0.02082,-0.08332,0.00849,-0.02129,0.01269,0.00903,0.06412,0.00534,0.00986,0.06141,0.00395,-0.01182,-0.03417,-0.00475,-0.05459,0.02981,0.07827,-0.00642,-0.00292,0.01813,0.00794,0.02695,-0.00327,-0.03039,-0.02349,-0.02793,-0.01766,-0.00617,-0.03276,0.03989,0.02213,0.05481,-0.00175,0.05641,-0.04215,-0.00603,-0.00769,-0.0149,-0.0195,0.00331,0.02558,-0.00869,0.00247,-0.06077,-0.00313,-0.02133,0.01186,0.00131,0.0543,-0.00488,0.03237,0.05419,0.00253,-0.01099,-0.02786,-0.00315,-0.01056,0.02683,0.01504,-0.0307,-0.02723,-0.00613,0.00942,-0.01572,0.03255,0.03092,0.00926,-0.09185,-0.00088,-0.01742,-0.01393,-0.00107,-0.04429,0.01011,-0.02442,0.01397,-0.00675,-0.01565,-0.02949,0.00372,0.0093,0.00521,-0.05646,-0.04679,0.01803,0.00991,0.02045,-0.03471,-0.00408,0.01023,0.03175,-0.04637,-0.05349,0.02942,0.01496,0.02599,0.01892,-0.02655,-0.06611,0.04118,0.00039,0.04779,0.03233,-0.01085,-0.02995,0.02695,-0.00675,0.02619,0.03567,-0.01001,0.03819,-0.00386,0.0656,-0.01882,0.06394,0.02894,0.0351,0.01636,0.02967,0.01591,-0.10575,0.02308,0.02106,0.01844,-0.02415,-0.04089,-0.04384,0.02303,0.04094,-0.00949,0.06876,0.00561,-0.06392,-0.03639,0.01252,0.02662,0.06823,0.03771,-0.05345,-0.08142,0.01481,0.00895,0.03867,0.03229,0.00707,0.05903,-0.01957,-0.00754,-0.01496,0.01594,0.03225,0.02417,-0.01409,-0.07811,0.03262,0.00844,-0.03163,0.00423,-0.02437,0.0229,0.08999,-0.00429,0.00889,0.02429,-0.02475,-0.03204,0.00223,0.00156,-0.01466,0.06603,0.03859,0.00904,-0.03052,-0.03933,-0.02538,-0.01323,0.04414,0.0176,-0.00572,0.04661,-0.02045,0.0289,0.05056,0.02037,-0.01196,-0.01262,-0.03216,0.00582,0.03141,0.10018,-0.00577,0.05223,0.02398,0.01164,0.0008,0.03708,-0.02974,0.03236,-0.03729,-0.04834,0.05189,0.03563,0.01355,0.03813,0.01601,0.02542,-0.08265,0.01138,-0.00635,-0.00603,-0.02471,0.00276,-0.0662,-0.06385,-0.02073,-0.07491,-0.01386,0.01725,-0.0613,0.05303,0.02546,0.05004,0.01924,-0.02212,0.02255,-0.03121,-0.01566,-0.05959,0.02174,0.03205,0.01468,-0.01408,0.01047,0.02777,-0.00525,0.03801,0.02037,0.00928,0.03214,-0.00085,-0.07095,0.01986,-0.06237,-0.00788,-0.05625,0.05165,-0.04114,-0.00124,-0.06489,-0.0278,-0.00076,0.01406,-0.0186,0.03846,-0.00572,0.01342,-0.07575,-0.02121,0.02684,0.03365,0.03463,-0.01079,-0.08904,0.02566,0.03957,-0.03157,-0.0165,0.00738,0.01222,-0.07699,-0.00371,0.01523,-0.02969,0.00481,0.06849,-0.03253,0.02341,-0.05365,-0.02461,0.00686,-0.0313,-0.0211,0.03143,-0.00197,-0.00177,0.04485

paradigms\nLearning Outcomes:\n- Describes the evolution of programming language in terms of generations\n- Compares and contrasts imperative, declarative, object oriented languages\nEvolution of programming languages\nThe programming language is a set of commands written in a specific format and\ngrammar, and it has to be learnt just like learning another language to understand a\nforeign language to communicate with a foreigner. C, C++, Python, Pascal, Java, etc. are\nsome common programming languages.\nOnce the pseudocode which is general and not specific to any programming language is\nwritten, it should be converted into a specific programming language of choice and based\non the type of application and expertise.\nThe programming language is the language understandable to humans and to computers\nonce compiled. There are many different languages that are suitable for different\napplications: scientific calculations, database management, business applications etc.\nProgramming

There are many different languages that are suitable for different\napplications: scientific calculations, database management, business applications etc.\nProgramming paradigms\nComputer programming languages can be categorized into two broad categories\n(depending on how they work), they are known as programming paradigms.\n1. Imperative languages\nThis is the most common type. In this type, the problem is solved (the program is written)\nas a sequence of commands (imperatives).\nFurther, these languages can be categorized into three types:\n- Procedural. e.g: C\n- Object-oriented. e.g: Java, C++\n- Parallel processing.e.g: Java\nDeclarative languages\nThis type is less common.

and the type of program\ntranslators\nLearning Outcomes:\n- Describes the need of translation of a program\n- Compares the source and object program\n- Lists and briefly describes the types of program translators\n- Briefly describes the function of linkers\nProgram translation and the type of program translators\nSource Program and Object Program need to be translated into machine code.\nSource code\nA program written in a high-level language like C, Python, etc. can be understood by humans\nwho know the particular language.\nObject code\nSource code which is not understandable by computers directly without being converted to\nwhat is known as the machine language, should be converted into machine language using an\nintermediate program.

This is something humans cannot learn and memorize due to the enormous amounts of\ndigits and the vulnerability of mistakes.\nTo overcome the above-mentioned difficulty, once the human-understandable source code\nprogramming is done, an intermediate program converts it into a corresponding object code\ncontaining binary values.\nThere are two ways – interpreting and compiling - of conversion.\no Interpreter\nThe interpreter converts the source code into an object code line by line. Due to its’ nature,\nthis process has to be repeated every time the program is run, and therefore, the execution\ntime is high. Some languages like BASIC, FORTRAN, and Python use this type of\nconversion.\no Compilers\nA compiler converts the whole of the source code into object code at once.

Identifies the basic features of IDE\n- Practices the instructions to\no Open and save files\no Compile, execute programs\n- Uses the debugging facilities in IDE\nIntegrated development environment (IDE)\nIntegrated Development Environment is essential to handle the source code. Most IDE’s consists\ncode editor, compiler, debugger etc.\nAs mentioned above, once the source code is written in a high-level language, it is compiled to\nan object code ready for execution.\nLet’s see what happens in the process and what programs are responsible for each of these\nstages.\nEditing using Editors – This is the first phase of the process. The algorithm has to be converted\nto statements according to the syntax (grammar) of the language, and these statements have to be\ntyped for further processing. This process is called Editing and the software that helps to do this\nwork is called Editors. There are various types of Editors providing different features.

This process is called Editing and the software that helps to do this\nwork is called Editors. There are various types of Editors providing different features. For\nexample, three main functions of an Editor are creating a new file, saving a file, Opening a saved\nfile etc. Basically, an Editor is word processing software with minimal features.\nDebugging/ Compiling using Compilers – After the program editing is over, a source file is\ncreated. As mentioned above, this source file has to be converted to an object file by compiling.\nIn the process of compilation, another process called debugging is taking place. This is the\nprocess that detects the syntax errors in the source file. Debugging can be done before compiling,\nbut most of the time, debugging and compilation are happening simultaneously.

handled using variable names. Logically, before using a\nvariable, it has to be defined. So, we define the program variables, before the Input section.\nAs mentioned earlier, a program uses predefined functions like print(), writeln() etc. These\nare stored in a library, and these library functions have to be loaded at the beginning.\nAccordingly, a structure of a program looks as follows:\nStart\nImporting essential libraries\nDeclaration of variables/ constants\nInput data\nProcessing\nOutput results\nEnd\n- Comment\nIn a program, it is necessary to identify and understand the functions of different lines in an\nordinary language understandable to humans. As we know, the program contains the\nlanguage understandable to the computer, so to bridge the gap, we write comments at the\nbeginning or end of commands.

Different\nlanguages use different rules for naming objects. In Python the following rules must be observed\nin naming objects.\n- An Identifier name in python must start with a letter or underscore character\n- After the first letter, the remainings of an identifier name can contain alpha-numeric\ncharacters and underscores and numbers (A-z, 0-9, and _ )\n- There is no limit to the maximum length of an identifier name\n- Python keywords can't be used\n- Identifier names are case-sensitive (age, Age, and AGE are three different variables)\nVariable\nA variable is the symbolic name assign for a place in the computer's memory where one can\nstore data.

execution","vector":[-0.00244,0.0356,-0.15752,-0.07957,0.07117,0.0062,0.01634,0.0125,-0.00807,-0.0423,-0.05765,0.03613,0.08626,0.01419,-0.00147,-0.10511,-0.00468,-0.06878,0.04093,0.05217,-0.00669,-0.03251,-0.0176,0.03163,0.09736,-0.00343,0.01076,-0.05272,-0.04338,0.03169,-0.01507,0.03415,0.0297,-0.03166,-0.03989,-0.04959,0.04368,0.03394,0.03787,0.03073,-0.00649,0.01949,0.0271,0.00526,0.02522,-0.01709,0.02197,-0.01325,0.00355,0.00597,0.02114,-0.0692,-0.00581,0.00974,0.07827,0.05823,0.01322,0.01023,0.03025,-0.01455,0.08204,0.0755,-0.06098,0.04852,0.06339,-0.01369,-0.04075,0.04861,-0.01213,0.02049,0.03601,-0.04953,0.04209,0.02727,-0.04469,0.04643,-0.03342,-0.03052,0.02612,0.05281,0.01,0.00761,0.03248,-0.00676,0.04673,0.00413,-0.06498,0.02951,-0.00556,0.06351,-0.02627,0.0072,0.00498,0.0116,-0.05749,0.03751,-0.03358,0.03575,-0.02016,-0.02333,-0.00372,-0.02846,0.0125,-0.05788,0.07054,0.05121,0.02961,-0.03801,-0.03966,-0.02315,-0.0042,0.03832,-0.03773,-0.02751,-0.02872,0.00839,0.09055,-0.07025,0.01567,0.03005,0.00113,0.00925,0.02938,0.02782,0.00752,0.02082,-0.05241,-0.00362,0.01009,-0.03192,0.00821,-0.03663,-0.03348,-0.00955,0.01501,0.05674,-0.02997,-0.04289,0.03657,-0.0006,0.03706,0.02604,-0.02407,-0.02268,0.01995,-0.04668,0.04887,-0.02889,0.00743,0.03534,0.02696,0.06521,-0.01666,-0.0058,-0.00015,-0.021,0.01203,-0.00877,0.04296,0.01096,0.05938,0.00746,-0.02824,0.04724,-0.04458,-0.04875,0.02341,-0.02396,0.00258,0.01576,-0.05132,-0.05303,-0.01117,-0.01618,0.034,-0.01932,0.01647,-0.02537,0.02263,-0.00806,0.0285,-0.10172,0.06455,0.02081,-0.03534,-0.00864,0.01516,-0.02897,-0.03745,-0.04017,-0.01612,0.05405,-0.01863,-0.02342,-0.04444,-0.06154,0.03314,-0.01741,-0.00456,-0.02473,-0.02332,-0.0137,-0.06757,0.04898,-0.03971,0.06196,-0.00735,0.00926,-0.03552,0.02463,0.08311,-0.01227,-0.02234,0.05553,-0.00801,-0.0406,0.0109,-0.02839,-0.01679,0.00529,0.03896,-0.00971,0.00925,0.0031,0.01581,0.028,-0.05482,0.01943,-0.05837,0.01165,-0.033,-0.07746,0.06006,-0.00637,0.03482,0.02319,0.01957,0.05024,-0.0004,0.01472,-0.02695,0.0038,0.01021,0.01805,-0.04806,0.01998,0.00374,-0.03618,-0.03109,0.06367,-0.03203,-0.01298,0.01577,0.03404,0.04658,-0.01873,-0.01378,0.01178,0.02895,-0.02412,0.03017,-0.03044,0.00614,-0.01758,-0.03783,-0.03143,0.0129,-0.02552,0.00792,-0.01652,-0.01587,0.02752,0.01699,-0.015,0.01528,-0.01056,0.01857,-0.0057,0.01605,0.02473,0.02285,-0.04962,-0.06805,0.02865,-0.01794,0.06381,0.02206,0.00915,-0.02597,-0.0527,0.04177,0.01687,-0.05226,-0.01042,0.01753,0.01235,0.03996,0.0153,0.02948,-0.00185,0.01374,0.03497,0.05445,0.00981,0.02399,-0.02164,-0.01741,-0.00364,0.02118,-0.00113,-0.03194,0.04291,-0.0583,0.03736,-0.0434,0.04187,-0.01412,0.02825,0.05481,-0.01297,-0.02491,-0.06554,0.05195,-0.01362,0.01091,0.05422,-0.00582,0.02556,-0.02776,-0.02856,0.0256,0.0225,0.00117,-0.02124,-0.03756,0.01819,0.0114,-0.03137,-0.02129,0.05898,0.11269,-0.01054,0.04266,-0.03793,-0.00793,-0.00637,-0.01775,-0.03931,0.0185,0.0448,-0.03694,0.03801,-0.02013,-0.0174,0.01932,-0.02814,0.03487,0.01041,-0.04076,0.0164,0.0263,0.03882,0.03181,-0.04578,0.04094,0.00099,0.03052,-0.00715,0.01315,-0.02966,-0.00714,-0.01778,0.00111,0.00023,-0.01275,-0.01795,-0.06458,-0.01586,-0.02026,0.00766,-0.0128,-0.04135,-0.01357,0.00906,0.0044,-0.00894,-0.01886,-0.0139,0.02166,0.01846,0.01481,-0.01473,-0.03945,0.00934,0.02887,-0.02187,0.05192,0.02975,-0.02926,0.02584,-0.0773,-0.05463,0.0387,-0.00412,0.01761,0.04512,-0.0112,-0.04176,0.04487,-0.00913,0.01058,0.04692,0.01332,-0.05199,-0.0212,0.0203,0.03222,0.02538,-0.04418,0.01853,0.06241,0.06047,-0.01046,0.01994,0.00791,-0.02078,0.04565,0.08032,0.00119,-0.08427,-0.01457,0.05817,0.04341,0.03057,-0.0025,-0.00012,0.02296,-0.01187,0.02021,0.05731,0.04197,-0.04365,-0.03263,0.00214,0.02059,0.10678,0.05921,-0.02286,-0.04997,0.04786,-0.00305,0.03316,0.03283,-3e-05,0.09073,-0.00975,0.01691,-0.00415,-0.00487,0.02541,-0.00095,0.01507,-0.05417,0.01336,-0.01176,-0.04535,0.00494,-0.01834,0.02218,0.08713,-0.02978,0.03174,0.03907,-0.00192,-0.00736,-0.0128,-0.00143,0.00497,0.02525,0.02248,-0.03037,-0.0139,-0.05083,-0.01375,-0.00372,0.00429,0.01071,-0.01303,-0.01187,-0.02511,0.05247,0.02723,0.04525,0.02161,-0.05104,-0.07242,-0.02598,0.04347,0.04218,0.02305,0.00816,0.03957,0.00296,-0.00617,0.03802,-0.01964,0.04809,-0.0686,-0.03284,0.01033,-0.00989,0.01328,0.00877,0.02035,0.02972,-0.02216,0.01509,0.02662,-0.03954,0.00389,-0.00169,-0.05561,-0.01164,-0.06532,-0.06441,0.03637,0.01896,-0.06527,0.06416,-0.00674,0.0539,0.01011,-0.06642,0.00402,-0.0358,-0.04542,-0.06429,0.059,0.00785,0.00144,0.00633,0.018,0.00664,-0.00934,0.0465,-0.00159,-0.00305,0.0172,-0.03684,-0.0675,0.04036,-0.02215,0.00205,-0.03139,-0.00263,-0.02838,0.00367,-0.01748,-0.02328,-0.03187,-0.0617,0.03827,0.02497,0.0252,-0.02315,-0.0154,-0.03025,-0.03803,0.0197,0.04743,0.006,-0.08887,0.00991,-0.01381,-0.01255,-0.01472,0.01096,0.00027,-0.06285,-0.04816,0.01351,-0.03735,-0.02308,0.00733,-0.02596,0.00125,-0.00999,-0.02315,0.00481,-0.01498,0.034,-0.02931,-0.01194,-0.02538,0.01403,0.01793,-0.

Outcomes:\n- Briefly describes control structures\n- Lists and briefly describes the types of control structures\n- Uses control structures appropriately in programming\n- Applies nested control structures in programs\nControl Structures\nThe flow of Control:\nThe flow of control in a program is implemented with three basic types of control structures:\n- Sequential: Code statements are executed sequentially. (One line after another)\n- Selection: Used to specify one or more conditions to be tested by the program.\n- Python programming language provides the following decision-making statements:\n- if\n- if-else\n- if-elif-else\n- Repetition: Used to execute a statement or group of statements multiple times.

the functions\n- Lists and briefly describes the types of functions\n- Identifies the structure of a function\n- Compares local and global variables\n- Identifies the behavior of a variable in terms of life time\n- Identifies the need of return values and writes functions to obtain the appropriate return value\n- Writes functions using relevant parameters and arguments\n- Uses user defined functions\nFunction\nA function is a block of code which only runs when it is called.\nYou can pass data, known as parameters, into a function.\nSo the function can return data as a result.\nCreating Functions in Python\nIn Python a function is defined using the def keyword:\nExample:\ndef my_function():\nprint(\"This is my first function\")\nCalling a Function\nTo call a function, use the function name followed by parenthesis:\nExample 20:\nCodeOutput\nParameters\nInformation can be passed to functions as a parameter.\nParameters are specified after the function name, inside the

program. This depends\non where you have declared a variable.\nThe scope of a variable determines the portion of the program where you can access a particular\nidentifier.\nThere are two basic scopes of variables in Python:\n- Global variables\n- Local variables\nGlobal vs. Local variables\nVariables that are defined inside a function body have a local scope, and those defined outside\nhave a global scope.\nThis means that local variables can be accessed only inside the function in which they are\ndeclared, whereas the global variables can be accessed throughout the program body by all\nfunctions. When you call a function, the variables declared inside it are brought into scope.\nExample

Uses basic file operations (open, close, read write and append)\nPython File Handling\n- Python has several functions for creating, reading, updating, and deleting files\n- Uses basic file operations (open, close, read-write and append)\n- The key function for working with files in Python is the open() function\nThe open() function takes two parameters; filename and mode.\nThere are four different methods (modes) for opening a file:\n\"r\" - Read - Default value.

file if the specified file does not exist\nExample 60:\nCreate a file called \"n2.txt\":\nCode Output\nf = open(\"n2.txt\", \"x\")\nDelete a file\nTo delete a file, you must import the OS module, and run its os.remove() function:\nRemove the file \"n1.txt\":\nimport os\nos.remove(\"n1.txt\")\nCheck if file exists and then delete\nTo avoid getting an error, you check if the file exists before you

appropriately\n- Implements bubble sort technique appropriately\nMySQL Searching Techniques\nSearching is the algorithmic process of finding a particular item in a collection of items. A search\ntypically answers either True or False as to whether the item is present.\nIn Python, there is a very easy way to ask whether an item is in a list of items. We use\nthe in operator.\nMySQL Sequential Search\nWhen data items are stored in a collection such as a list, they have a linear or sequential\nrelationship. Each data item is stored in a position relative to the others. In Python lists, these\nrelative positions are the index values of the individual items. Since these index values are\nordered, it is possible to visit them in sequence. In this type of search, a sequential search is\nmade over all items one by one. Every item is checked and if a match is found then that\nparticular item is returned, otherwise the search continues till the end of the data structure.\nSorting

Every item is checked and if a match is found then that\nparticular item is returned, otherwise the search continues till the end of the data structure.\nSorting Techniques:\nSorting refers to arranging data in a particular format. It can be ascending or descending order.\nSorting algorithm specifies the way to arrange data in a particular order.\nBubble sort:\nThe bubble sort makes multiple passes through a list. It compares adjacent items and exchanges\nthose that are out of order. Each pass through the list places the next largest value in its proper\nplace. In essence, each item “bubbles” up to the location where it belongs.\nSorting list in ascending order:\n- compare 1st and 2nd elements\n- if 1st is larger than the 2nd, swap\n- compare 2nd and 3rd,

by Tim Berners Lee in 1989 at the European Centre for\nNuclear Research, as a major application on the\nInternet. It was the first application on the Internet\nthat caught the attention of the public and it\ndramatically changed how people interact with the\nnetwork of computers. Essentially, the World Wide\nWeb (WWW) is an application that runs on top of\nthe Internet, which is in turn made up of a lot of\ninterconnected computers. According to Wikipedia,\nWorld Wide Web is an information system where\ndocuments and other web resources are identified by Uniform Resource Locators(URLs), which\nmay may be interlinked by hypertext, and are accessible over the Internet.

a background colour of choice by adding an extra attribute to the\n<body> tag.\nE.g. <body bgcolor=\"#E6E6FA\"> can be used to assign a background colour to the html\ndocument.Syntax of it is <body bgcolor=\"color_name|hex_number|rgb_number\">, where\ncolor_name can specify a particular colour such as “Blue”, hex_number can specify the hexa\ndecimal code of a colour, and rgb_number can specify the RGB code.\nNote: This facility for setting background colour is available in previous versions of HTML and,\nin HTML 5 these will come under CSS. We will cover them when we study CSS later in this\nchapter.\nHeading tags in HTML:\nHeadings are used to separate and introduce major divisions within a web page.

We will see it later\nwhen we study the Cascading Style Sheets.\nNote: Unordered lists and ordered lists can be combined in any sequence by nesting one within\nthe other.\nUnordered List:\nIn HTML, an unordered list is composed of two tags: <ul> and <li>. The <ul> tag is the\noutermost structure that declares the unordered list. Within the <ul> tag, a series of <li> tags\ncreates the items in the list. Here’s a short example of the HTML code for an unordered list:\n(write about the bullets in lists and there are many different styles to include)\n<ul>\n<li>Tomatoes</li>\n<li>Onion</li>\n<li>Garlic</li>\n</ul>\nFigure 3.3.6\nNote: The <li> tag can contain any amount of text, from a single word to multiple lines of text.\nBullets in a list can be a standard unordered list gives equal weight to all the bulleted items, one\nafter another. In some situations, it is desirable to depict multiple levels of content with

In some situations, it is desirable to depict multiple levels of content with sub-\nitems. HTML provides the capacity to incorporate any level of sub-items desired by nesting <ul>\ntags.\nLike unordered lists, the numbered variety uses two key elements: an outer wrapping tag and a\nseparate tag for each list item. The only difference is that the outer tag is not <ul> but ol>.\nHere’s a brief example:\n<ol>\n<li>Pull mask from overhead bin</li>\n<li>Place mask over face</li>\n<li>Pull strings tight</li>\n</ol>\nFigure 3.3.7\nTable\nIn html you can create a table using the three different tags: <table>: This is the outermost\nelement that contains the other two tags and all content. <tr>: The <tr> tag defines the table row\nand holds the final element. <td>: The <td> tag stands for table data; the complete <td> tag is\nalso known as a table cell.

hypertext markup language\n- Identifies the standards of HTML\n- Saves the source document with suitable extensions\n- Designs the web page by inserting appropriate multimedia objects according to user\nrequirements\n- Organizes data using lists and tables in the web page\n- Links pages and multimedia objects to the web page\nHTML to create linked web pages\nWe have looked at the basic structure of a web page that can be written using HTML, and a few\nother tags that can be included to create a web page. We have also seen that a designed web page\ncan be viewed using a web browser to view the content of the web page.

web pages to improve the appearance\n- Applies various CSS formatting in HTML web pages to improve the appearance\nStyle sheets to change the appearance of web pages\nCascading Style Sheets (CSS) provide the look and feel for the HTML content. CSS enables the\ndesigner to change how the text, images, and links appearon a web page quickly and easily.\nUsing the CSS, the designer has the freedom of styling the web page independent of the content\nusing a presentation layer where you can make global formatting options. The cascading part of\nthe CSS tells how the elements on a web page are affected by the CSS rules.

An external style sheet is connected to an HTML page in one of\ntwoways:either with a <link> tag or with a @import directive within a <style> tag. For example,\nsay you wanted to include the CSS rules written in a file called main.css. The <link> syntax\nwould look like this:\n<link href=”styles/main.css” type=”text/CSS” rel=”stylesheet” />\nThe href attribute provides the path to the external style sheet, and type specifies the kind of\ndocument the browser can expect.

this:","vector":[-0.01378,0.05518,-0.13926,-0.05729,0.0473,-0.00456,0.04786,0.0367,-0.02278,-0.07431,-0.01168,-0.00467,0.10247,0.02195,0.02126,-0.01512,-0.00648,-0.08408,0.04596,0.04858,-0.04185,-0.0609,-0.02803,-0.02448,0.05797,0.05967,0.04165,-0.00175,-0.10627,-0.03144,-0.03891,0.00754,0.01199,-0.0324,0.0058,-0.02183,0.01501,-0.00843,-0.05665,0.0366,0.02146,0.0149,0.02368,-0.04597,0.04357,-0.03058,0.02421,-0.03007,0.0508,-0.00268,0.02759,-0.01931,-0.02102,-0.04146,0.08863,-0.01619,0.01179,0.01878,0.06716,-0.00471,0.02354,0.0897,-0.05531,0.05372,0.03356,-0.01168,-0.01967,0.02975,-0.01089,-0.02884,0.02658,-0.01396,0.02693,0.00814,-0.06513,-0.04803,-0.00567,-0.01069,0.04403,0.0667,-0.04519,-0.04496,0.05594,-0.02192,0.06859,0.02525,0.0051,0.00322,-0.04969,0.04095,0.00541,-0.02827,0.0096,-0.00572,-0.07983,0.01071,0.02591,0.00603,-0.00011,-0.04709,-0.02873,-0.03909,-0.00711,0.00272,0.01805,0.0578,0.05085,0.03199,-0.00581,-0.05604,-0.00613,0.04425,-0.00819,-0.01152,0.01564,-0.02873,0.06285,-0.00482,0.02193,0.06869,0.00467,-0.04509,0.01508,0.05186,0.05673,0.03295,-0.02664,-0.018,0.04938,-0.0662,-0.05284,0.01113,-0.01488,-0.04169,0.07487,0.04405,-0.00463,-0.02749,0.02757,0.03583,0.0387,0.00937,-0.05186,-0.00978,0.02013,-0.02617,0.02446,0.0088,0.02153,0.02071,-0.01818,0.00529,0.0128,0.03219,-0.00778,-0.02859,0.0343,0.00095,0.02517,-0.00505,0.08607,-0.0214,-0.03365,0.07422,0.00833,-0.03495,-0.00028,0.05652,-0.00864,0.012,-0.0113,0.00274,0.00383,-0.01051,0.06441,-0.02113,0.07782,-0.04607,0.00111,-0.05556,-0.04894,-0.05289,0.02495,-0.02242,-0.01682,-0.01258,0.00552,-0.04001,-0.04915,-0.02983,0.01431,0.03006,-0.03809,-0.04467,-0.07237,-0.05261,0.03861,0.01885,0.01553,-0.01978,-0.01616,-0.00134,-0.03841,-0.00664,-0.03448,0.04363,0.00564,0.01859,-0.00176,0.0237,0.07592,0.00972,-0.02274,0.01514,-0.01404,0.05863,-0.01938,0.0038,-0.04807,0.06652,0.03571,0.05952,0.0076,0.01085,1e-05,-0.0291,-0.06579,-0.00305,-0.02853,0.01768,-0.01772,-0.06664,0.03422,0.00485,-0.00794,0.00922,0.01794,0.02631,0.00668,-0.03305,0.03146,-8e-05,-0.00115,-0.00414,-0.05135,0.03111,0.00435,-0.03441,0.02685,0.09088,0.01765,0.01639,0.01437,0.00369,-0.01793,-0.07643,-0.04318,0.0032,-0.01984,-0.01739,0.02983,-0.03719,0.02721,0.00292,-0.05095,-0.03189,-0.00693,0.01658,0.04999,-0.01139,-0.01285,0.04104,-0.04741,-0.00614,0.01572,0.01681,0.00315,-0.04155,-0.00066,0.06625,0.00535,-0.09021,-0.06379,0.00401,-0.01248,0.07154,0.05443,0.01267,-0.04424,-0.04399,0.0014,-0.01004,-0.04206,0.01602,0.03926,0.01806,0.0913,-0.00322,-0.00285,-0.04781,0.02003,0.04158,0.06305,0.00776,0.01902,-0.04192,0.01333,-0.02662,0.05562,0.00202,-0.04134,-0.01238,-0.00195,0.05228,-0.03902,0.05005,0.00489,0.0236,0.055,-0.02485,0.0031,0.01319,0.00575,-0.01582,-0.01049,0.02519,-0.00093,-0.01742,0.00155,-0.02508,0.01518,0.0846,-0.01272,-0.03383,-0.00031,0.01967,0.0298,-0.00968,0.00289,0.03312,0.09046,-0.02025,0.03762,-0.00915,0.01399,-0.03082,0.00383,-0.01958,-0.03787,0.07219,-0.04335,0.05164,-0.02189,-0.00056,-0.00996,-0.03694,0.01199,0.04602,-0.00632,0.01936,0.04125,0.03238,0.03156,-0.05481,0.04298,0.03801,-0.00584,0.01309,0.02385,0.00745,-0.01235,-0.02253,0.02647,0.0043,0.04479,0.04023,-0.03751,0.03211,0.01782,-0.00325,0.03161,0.03353,-0.0251,-0.03738,0.02501,5e-05,-0.03233,-0.01841,0.05202,0.06431,-0.01397,-0.02132,0.0229,-0.002,0.00886,0.00549,0.00336,0.02372,0.00084,0.03284,-0.08411,-0.08697,0.00869,-0.02534,-0.05082,0.05625,-0.0025,-0.02932,0.04432,-0.04597,0.04712,0.01462,-0.02995,0.00474,-0.02414,0.0504,0.0501,0.02585,-0.05109,-0.00056,-0.00093,0.04876,-0.0143,0.01587,0.04884,0.01471,0.01073,0.01753,-0.00674,-0.07426,-0.00856,0.01823,0.00421,-0.02088,-0.01215,0.04709,0.01301,0.04534,0.00453,0.02907,0.04688,-0.04611,0.0012,0.02142,-0.03036,0.12249,0.01129,-0.01029,-0.02999,-0.00218,-0.00649,-0.00468,0.00436,0.0201,0.06674,-0.05195,-0.02162,0.01259,0.00787,0.05771,0.00759,0.02751,-0.052,0.00872,-0.02639,-0.04542,0.01258,0.02446,0.01681,0.07596,-0.03142,0.01061,0.04869,-0.03279,0.04705,0.04537,-0.01945,-0.01563,-0.01833,0.0202,-0.02198,-0.03889,0.01925,-0.02622,-0.02179,-0.02177,0.02243,-0.01478,0.03215,0.0082,0.02361,0.00563,0.02103,0.00098,-0.02463,-0.01136,-0.03077,0.00497,0.03008,-0.05377,0.01757,0.01328,-0.01006,0.00107,0.02347,-0.02943,0.0016,-0.03734,-0.02014,0.00731,-0.06174,0.01182,0.02118,0.00193,0.05306,-0.03709,-0.01477,0.0339,-0.03668,-0.00161,-0.00058,-0.05493,-0.03006,-0.0004,-0.04553,0.01766,-0.01681,-0.06398,0.02943,-0.01144,-0.04736,0.04246,-0.01899,0.04555,0.01192,-0.04257,-0.06803,0.0363,0.02962,-0.00142,0.00219,-0.01023,0.01068,-0.02662,0.01097,0.00459,-0.01546,-0.01636,-0.03751,-0.04116,0.02948,-0.02215,0.01288,-0.04973,0.01123,-0.03763,0.00964,-0.00138,0.01883,-0.03623,0.02519,0.01557,0.03479,-0.02144,0.01503,0.00163,0.02189,0.00697,-0.01162,-0.0039,0.01435,-0.10152,0.01778,0.00434,-0.05516,-0.0153,0.03794,-0.00963,-0.05824,-0.00928,0.00066,-0.04524,-0.02039,0.00686,-0.02569,-0.01103,-0.0235,-0.04938,-0.01077,-0.10949,-0.01816,0.01115,0.00249,0.01742,0.03524,0.03

attribute within an HTML tag. For example, if you\nwant to colour a<h1> tag red with in an inline style, your code would look this:\n<h1 style=\"color: red;\"> Important Message Ahead</h1>\nCSS selectors\nIn CSS there are four basic types of selectors:\n- Tags: An HTML tag can serve as a CSS selector. The use of HTML tags as a CSS\nselector is very straightforward. When an HTML tag, such as <p>, is defined as a selector\nwith CSS, all <p> tags are immediately affected unless another CSS style overrules it.\n- IDs: Typically ID selectors are intended to be used once per HTML page. An ID can be\ndefined by using a leading hash (#) symboland can then be applied in an HTML tag using\nID attribute.

Outcomes:\n- Defines dynamic web pages\n- Creates data source and enters data\n- Creates PHP code to save/retrieve data to and from MySQL\n- Develop simple web based information systems\nDynamic web pages using PHP and MySQL\nWeb sites can be classified as static web sites or dynamic websites. In static websites, the HTML\nand CSS are used to design the web pages and the content is pretty much static in its nature. In\ndynamic web pages, the HTML, CSS, PHP along with some database management system,\npreferably MySQL, are used therefore the website provides more interactive content to the user.\nDynamic web pages are more interactive web pages where a user requests something from the\nweb page and then obtains it as a result of his query. We have already seen the properties of\nHTML and CSS.

Array\nkeys (or indexes) may be either integers or string whereas values can be any type. An array can\nbe declared using the array() language construct. There are three different types of arrays in\nPHP, indexed arrays, associative arrays, and multidimensional arrays.\nIndexed Array\nAn indexed array named fruits with three elements can be created as follows:\n$fruits = array(\"Banana\", \"Apple\", “Orange”);\nOr\n$fruits[0] = “Banana”;\n$fruits[1] = “Apple”;\n$fruits[2] = “Orange”;\n- Associative

statement when there are multiple actions that\nneed to be taken based on multiple conditions. The switch statement in PHP has the following\nsyntax:\nswitch (n) {\ncase label1:\ncode to be executed if n=label1;\nbreak;\ncase label2:\ncode to be executed if n=label2;\nbreak;\ncase label3:\ncode to be executed if n=label3;\nbreak;\n...\ndefault:\ncode to be executed if n is different from all labels;\n}\nIn the above syntax of the switch statement, based on the evaluated value of the variable n, it is\ncompared with the values of each case, and when there is a match, the code attached will be\nexecuted. The break command is included at the end of each block of code that is attached to\neach case to prevent the next block of code is executed automatically.

first checks for a condition and if\nthe condition is evaluated true, then shall execute the set of commands within the loop until\nthe condition becomes false.\nAn example for a while loop in php is given below:\n<?php\n$count = 1;\nwhile ($count <= 12)\n{\necho \"$count times 12 is \" . $count * 12 . \"<br>\";\n++$count;\n}\n?>\nwill exit.\nThe above loop will execute 12 times and as soon as the value of count becomes 13, the loop\n- Do ... While loop\nDo while loop is a slight variation of a while loop where the looping structure allows the\nexecution of the set code at least once, and then allows execution of the code based on the\ncondition after that.\nThe following example illustrates the structure of a do while loop:\n<?php\n$count = 1;\ndo\necho \"$count times 12 is \" . $count * 12 . \"<br>\";\nwhile (++$count <= 12);\n?>\n- For Loop\nA for loop statement takes three parameters namely, an initialization expression, a condition\nexpression, and a modification expression. The syntax of the for loop will be as follows:","vector":[0.05005,0.01348,-0.16694,-0.01023,0.04022,-0.06666,0.06017,-0.01545,0.00524,-0.04198,-0.03939,0.02821,0.06249,0.01792,-0.00241,-0.06055,-0.02695,-0.08529,0.00713,-0.01982,-0.02106,-0.00974,-0.04663,-0.00899,0.09568,0.04251,-0.02737,0.02194,-0.05716,-0.0049,-0.07043,0.01634,-0.00522,-0.06531,-0.0342,-0.06379,0.00918,0.03157,0.0256,0.00806,-0.00939,0.02248,0.00543,-0.03078,0.06574,-0.05685,0.07528,0.01897,0.0321,-0.08037,0.01316,-0.03689,0.03291,-0.031,0.0772,0.0417,-0.04499,0.01907,0.02017,0.01624,0.09604,0.04019,0.01268,0.04581,0.04198,-0.03301,-0.04407,0.00774,-0.01931,0.03505,0.0276,0.00643,-0.01708,-0.01945,-0.01617,0.05066,-0.04464,0.00068,-0.0148,0.03555,0.03982,-0.00643,0.04792,-0.04083,0.03455,-0.03862,-0.04413,0.01027,-0.03976,0.03264,0.00366,-0.04398,0.07343,0.04653,-0.08,-0.02599,-0.03082,0.00774,-0.03867,-0.00919,-0.02566,0.01247,0.00379,-0.03224,0.02081,0.01741,0.04772,0.00027,-0.04148,-0.03371,0.01897,-0.01045,-0.00598,0.00635,-0.0491,-0.01685,0.10265,-0.03545,-0.01829,0.03048,-0.0362,-0.07529,-0.02042,0.02775,0.05822,0.05795,-0.02427,0.04236,0.01273,-0.02145,0.00171,0.00993,-0.04166,0.01814,0.00785,-0.00406,0.00729,-0.03224,0.04617,0.00454,0.05124,-0.03233,-0.02263,-0.03178,-0.00119,-0.03747,0.06302,-0.01755,0.03397,-0.02769,-0.00011,0.01007,-0.01222,-0.01545,0.04544,-0.00874,0.02152,0.02869,0.0578,0.04716,0.05867,-0.0136,-0.02413,0.06797,-0.07729,-0.03285,0.00614,0.06035,0.00299,0.02424,-0.03127,-0.02975,0.00666,-0.01964,0.02638,-0.00662,0.01522,-0.04729,0.03654,-0.03027,0.00147,-0.03158,0.03604,0.01133,-0.01137,0.00373,-0.01902,-0.04582,-0.04995,-0.09881,-0.01625,0.01103,-0.02579,0.00527,-0.08274,0.0061,0.02134,-0.0367,0.08098,-0.03554,-0.01755,0.00014,-0.03454,0.0017,-0.0524,0.05706,-0.00409,0.04206,-0.05338,0.05074,0.11306,-0.02899,0.00264,-0.00425,0.00215,-0.00388,-0.0192,0.013,0.01024,0.01544,0.07638,0.00333,0.03854,0.00451,0.01472,0.01532,-0.03621,0.00314,-0.02518,0.01543,-0.00649,-0.07689,0.00303,-0.01719,0.04069,0.03718,0.01769,0.04202,-0.00948,-0.00527,-0.02357,-0.00343,0.03073,0.00186,-0.02246,-0.00329,0.00062,-0.02006,0.02318,0.0526,-2e-05,-0.04501,0.03264,0.04267,0.02303,-0.01704,0.00976,0.00926,0.05427,-0.01444,0.02457,-0.00658,0.00126,0.00279,-0.05427,-0.10208,0.00713,-0.03346,-0.00672,-0.02803,0.01134,0.00387,0.0094,0.0043,-0.01147,-0.00095,0.05085,-0.02704,-0.00546,0.04202,0.01828,-0.03804,-0.02352,0.03215,0.02711,0.01843,0.02156,0.01153,-0.00538,0.00025,0.02397,-0.03598,-0.04344,0.03879,-0.01345,0.04868,0.02366,-0.04831,0.05639,-0.01946,0.02122,0.05279,0.04131,-0.00525,0.00682,-0.0393,0.04578,-0.00192,0.02774,-0.00281,-0.02272,-0.0496,-0.03893,0.03591,-0.06569,0.06158,-0.01772,0.04414,0.05456,-0.04034,-0.03263,-0.05045,0.04021,-0.0296,0.01539,0.02588,-0.01546,0.0129,-0.05043,-0.03073,0.01751,0.05032,-0.02132,-0.05156,0.00448,-0.04697,-0.03712,0.01574,0.01156,0.0346,0.04726,0.00039,0.02368,-0.02723,-0.00809,-0.00396,0.01625,-0.00042,0.04279,0.02832,0.02808,0.01521,-0.0149,0.01909,0.0106,-0.02006,0.02163,0.00573,0.02542,-0.0003,0.05345,0.0155,-0.01833,-0.03925,0.00885,0.04524,0.00659,-0.00649,0.04438,-0.0431,-0.00788,0.00056,-0.0021,0.01401,-0.00735,-0.00768,-0.04862,-0.002,-0.00434,0.04262,-0.00314,-0.04419,0.0111,0.00334,-0.03499,-0.01028,-0.00569,-0.04405,-0.03524,0.01349,-0.01648,-0.02358,-0.05315,0.00891,0.06117,-0.01582,-0.01186,0.02447,0.04221,0.02911,-0.00623,-0.07927,-0.01272,-0.00923,-0.02881,0.00457,0.00618,-0.02419,0.03447,-0.00588,0.01779,0.07245,0.00097,-0.01737,-0.00747,0.03703,0.04209,0.02427,-0.01042,-0.01335,-0.00282,0.08787,0.01431,-0.00047,0.0455,0.0053,-0.00705,0.06563,0.03761,-0.11819,-0.01312,0.06361,0.0093,-0.01158,-0.01133,0.04553,-0.02079,0.04832,-0.00918,0.07801,0.07552,-0.06378,-0.02368,0.00989,0.01902,0.05767,0.00994,-0.01847,-0.02384,-0.00585,-0.05063,0.07043,0.01904,-0.00829,0.057,-0.04633,0.01711,0.02395,-0.02818,0.0355,0.02468,8e-05,-0.00918,0.00855,-0.0004,-0.03665,0.00668,-0.07508,-0.00841,0.06271,-0.02926,-0.01571,0.03871,-0.0211,0.02128,-0.06405,0.01451,0.01553,0.04088,0.04731,-0.00929,-0.00603,-0.03624,-0.03076,0.01867,0.00498,0.06734,-0.04373,0.02874,0.04031,0.08016,0.05884,0.03852,-0.02354,0.04666,-0.02337,-0.02842,-0.00893,0.01145,-0.06259,-0.01718,0.01676,-0.02395,0.01303,0.01337,0.00177,0.0171,-0.011,-0.02159,-0.00691,0.00641,0.02297,-0.00425,0.0254,0.06794,-0.07951,0.02801,0.03479,-0.04694,0.02858,0.01696,0.0032,-0.02598,0.03829,-0.00066,0.00071,-0.04091,-0.02264,0.04022,-0.00842,0.04368,0.01446,-0.05364,-0.03592,0.01121,-0.01831,-0.02749,0.01716,0.01302,0.02751,0.00571,0.03059,0.00764,0.0218,0.03497,-0.01415,-0.01574,-0.01634,0.02685,-0.04262,-0.03879,-0.02905,-0.00971,-0.03024,0.00888,-0.00565,-0.04946,0.00164,-0.01918,-0.02795,0.04806,0.02143,0.07352,0.03278,0.03739,-0.02239,-0.01101,0.0204,0.01561,0.04155,0.02043,-0.04775,-0.04157,0.00853,0.0081,0.02863,0.00131,0.00581,-0.03787,-0.03799,0.04651,-0.03401,0.06452,0.04317,0.0212,0.00697,-0.016,-0.023,-0.02841,-0.06277,-0.06113,0.06258,-0.01179,0.00338,0.01032,0.02

These portions (or blocks) of code can perform certain tasks and therefore can be called\nanywhere in the program as many times as needed. Writing functions reduce the repetition of the\nsame code in the program and it makes it much easier to modify the code only in one place rather\nthan at multiple locations.

created.","vector":[-0.01136,0.03489,-0.18998,-0.05372,0.06475,-0.06181,0.01128,-0.01331,-0.01728,-0.04321,-0.05623,0.0081,0.11537,-0.01354,-0.01088,-0.03293,-0.07603,-0.08383,0.01682,0.03067,-0.00944,-0.01837,-0.02594,-0.01486,0.05986,0.02799,-0.06023,0.02035,-0.04757,0.0251,-0.01842,0.07908,0.00991,0.0222,-0.00315,-0.0707,-0.02625,0.05458,-0.02989,0.01512,0.02731,-0.00136,0.01332,-0.01563,0.01248,-0.03425,0.05108,-0.01688,0.0368,-0.00201,0.03002,-0.05754,0.06839,-0.06187,0.06727,0.01821,-0.03471,0.03251,0.02349,-0.02469,0.07201,0.03961,0.00583,0.05219,0.02414,-0.00144,-0.04529,0.05684,-0.0184,-0.04577,0.00763,0.00415,0.007,0.03845,-0.0149,0.04387,-0.03928,-0.01294,0.01992,0.05508,0.02293,0.0092,0.04857,-0.0473,0.03498,0.0167,-0.02086,-0.01057,-0.0241,0.02529,0.00444,-0.01518,0.03168,0.0032,-0.04188,0.06723,0.01328,-0.02202,-0.06136,-0.02168,-0.00826,-0.00906,0.04836,0.00988,-0.00452,0.08059,-0.03434,-0.00863,-0.00821,-0.0173,-0.0435,0.06857,-0.02501,0.01309,-0.0271,-0.04353,0.08018,-0.01427,0.01093,0.01722,-0.0086,-0.00186,0.00348,0.00824,0.01503,0.02183,-0.02514,0.01115,0.02646,-0.04361,-0.04456,-0.01394,-0.03396,0.02394,0.04856,0.04545,0.0138,-0.03314,0.03431,0.01268,0.0293,0.00656,-0.04067,-0.06224,-0.00085,-0.05605,0.08689,-0.02622,0.02836,0.03168,-0.00171,-0.00598,-0.01448,-0.00355,0.02598,-0.01237,0.01415,-0.00219,0.02041,-0.00304,0.04587,-0.02767,-0.04275,0.05461,-0.02023,-0.0647,0.01248,0.02423,0.03257,0.04037,-0.01057,-0.05131,-0.00473,0.01779,0.01761,-0.04505,0.01676,-0.01536,0.05767,-0.00739,-0.0212,-0.08245,0.01885,0.01092,-0.02952,-0.00813,0.00901,-0.01614,-0.03269,-0.06222,-0.02239,-0.01355,-0.02927,-0.00084,-0.0569,-0.06377,0.0427,-0.00811,0.00586,-0.03991,-0.02197,0.0226,-0.03958,0.05962,-0.06991,0.02687,-0.01511,0.00916,-0.02632,0.06727,0.10454,-0.00872,-0.01754,-0.00871,-0.01567,-0.00765,-0.0374,-0.0104,-0.00445,0.02036,0.00377,0.01872,0.03142,0.00642,0.00309,0.01475,0.00576,0.04322,-0.008,-0.01538,0.00392,-0.10009,0.03492,-0.00098,0.02488,0.02813,-0.00364,0.09469,0.00235,-0.0041,-0.01125,0.00088,0.01437,-0.01662,-0.07682,0.00352,0.0018,-0.01964,0.02145,0.03124,0.01085,-0.03485,0.0128,0.04221,-0.03227,-0.06245,-0.00651,0.0036,0.0123,-0.00973,0.01046,-0.01786,-0.00011,-0.0312,-0.01177,-0.05038,-0.0487,-0.02846,-0.00062,0.0096,-0.01377,0.00616,0.01154,0.00623,-0.00284,-0.01937,-0.00107,0.05371,-0.04732,0.01312,-0.02442,-0.0966,-0.02262,0.02461,-0.00934,0.06756,0.02096,0.00343,-0.04829,-0.00596,-0.00657,-0.02245,-0.04314,0.01451,0.02367,0.00133,0.0321,-0.01165,-0.0143,-0.01086,0.0213,0.0365,0.05458,0.03236,0.01611,-0.01214,0.00155,-0.01779,0.0584,-0.01729,-0.04411,-0.0306,-0.04053,0.03884,-0.07031,0.03887,0.01831,0.0472,0.04418,-0.00894,-0.03683,-0.07189,0.02146,-0.01369,-0.01332,0.0675,-0.00253,0.01815,-0.02794,-0.03709,0.06053,0.02872,-0.03636,-0.0237,-0.03588,-0.01448,0.00826,-0.03947,-0.02056,0.05257,0.104,0.00625,0.00962,-0.05733,-0.03058,0.01048,-0.04106,-0.00683,-0.01053,0.0425,-0.00562,0.00614,-0.03545,0.02194,-0.01551,0.03672,0.01325,0.03694,-0.00987,0.0256,0.04302,0.03008,0.0244,-0.03203,0.00746,0.06064,0.01973,-0.02295,0.02333,-0.01834,-0.01883,-0.03343,0.01251,0.00398,0.04031,-0.00236,-0.06137,0.03596,-0.02042,0.01996,0.02689,-0.04161,0.02255,0.00916,-0.01619,0.00946,-0.01378,-0.00876,0.00858,0.02829,0.0165,-0.01029,-0.05336,0.00108,0.00077,0.02443,-0.02759,0.03073,0.03108,0.02269,-0.06206,-0.04954,0.02117,-0.00539,0.00707,0.01755,0.00414,-0.03639,0.03015,-0.00698,0.01704,0.03432,-0.0155,-0.0221,-0.00735,0.06763,0.03427,0.02083,-0.0172,-0.01816,0.03694,0.04749,0.03627,0.00317,0.07519,-0.05088,0.03853,0.04514,0.01812,-0.06195,-0.02612,0.05623,0.0423,-0.02287,-0.00199,0.0024,0.01657,-0.00236,0.02263,0.07124,0.05043,-0.05128,-0.01567,-0.02366,0.00438,0.10082,-0.0114,-0.02646,-0.00819,0.04016,-0.00745,0.05959,0.03565,-0.00453,0.09218,-0.05822,0.0369,0.01612,0.03817,0.04623,0.0088,0.03128,-0.05654,0.00571,0.00348,-0.04747,-0.00121,-0.04445,-0.00768,0.0218,-0.02378,-0.0305,0.02579,-0.02645,-0.02431,0.04316,0.04716,-0.01678,0.02452,0.00322,-0.02026,0.01095,-0.06117,-0.02733,0.05611,0.00049,0.04906,-0.01416,0.03749,0.04426,0.03718,0.02009,-0.02947,-0.03026,0.00515,-0.03686,-0.06089,-0.01706,0.0202,-0.03131,-0.01421,0.02749,-4e-05,0.01178,0.04205,-0.04979,0.06672,-0.03666,-0.01654,-0.01524,0.0011,-0.01994,0.02579,0.04913,0.05248,-0.05005,0.06077,0.09295,-0.01506,0.00569,-0.03967,-0.0429,-0.01157,-0.00114,-0.06423,0.02326,-0.02632,-0.05564,0.08446,-0.00225,-0.02589,0.00834,-0.05353,-0.01315,0.01865,-0.01101,-0.04994,0.03883,0.01398,-0.01101,-0.04626,0.00099,0.02312,-0.01568,0.05672,-0.02129,0.00085,-0.01223,0.00792,-0.00328,0.03768,-0.02551,-0.0021,-0.03241,0.01833,-0.03724,-0.01212,0.02199,-0.06259,-0.03295,0.01162,0.05333,0.02927,0.00949,-0.01162,-0.01422,0.02305,0.02003,0.02586,0.02374,0.00663,-0.09154,0.04308,-0.00809,0.03171,0.0252,0.02664,0.00428,-0.06809,-0.04721,0.03161,-0.07873,0.03701,-0.01187,-0.00182,-0.03288,0.01774,-0.00266,-0.04116,-0.02369,-0.02827,0.04322,0.02329,-0.0154,

from a table:-\nALTER TABLE <table name>DROP <column to be dropped>;\nExample:\nALTER TABLE classics DROP pages;\nIndexes in Databases\nIndexes in database tables help to search through the tables in a faster manner. Indexes can be\nadded to a table whenever it is created or at a later stage whenever needed. Indexes are actually a\ncolumn of data or a combination of more than one column of data that can be used to search\nthrough the table. With a judgment that requires the database designer to predict whether he/she\nwill be searching any of the data in that column, the database designer has to decide which\ncolumn would be used as an index. For example, in the table, classics, that we have already\ncreated, an index can be created based on the author or based on the title columns as follows:\nALTER TABLE classics ADD INDEX(author(20));\nALTER TABLE classics ADD INDEX(title(20));\nThe above commands will create indexes on both the author and title columns, limiting

to extract data from tables. The\nsyntax of using the select command:\nSELECT <column_name>\nFROM <table_name> ;\nThe following example illustrates how to select the author and title column data from the\nclassics table:\nSELECT author, title\nFROM classics;\nWHERE keyword: The where keyword enables you to narrow down queries by returning only\nthose where a certain expression is true. The syntax of using where keyword in an SQL\nstatement is as follows:\nSELECT <column_name>\nFROM <table_name>\nWHERE <conditional_expression>;\nFor example, to retrieve the rows that match the string “Mark Twain” for author name is written\nas follows:\nSELECT author, title\nFROM classics\nWHERE author=\"Mark Twain\";\nThe ORDER BY statement sorts returned results by one or more columns in ascending or\ndescending order. For example, the following query returns author name and title from the\nclassics table sorted in the author name order.\nSELECT author, title\nFROM classics\nORDER BY author;","vector":[-0.00789,0.00826,-0.15531,-0.0278,0.02611,-0.05877,0.02532,0.01058,0.02154,-0.02351,-0.03421,0.03747,0.11006,-0.03088,-0.02258,-0.02972,-0.04264,-0.05362,0.04855,0.04044,-0.04152,-0.03102,-0.0554,0.00354,0.08252,-0.00843,-0.07069,-0.00326,-0.05104,0.05654,-0.02738,0.0675,-0.01327,-0.01174,-0.04859,-0.09086,0.00406,0.01603,-0.03283,0.02491,0.03872,-0.01242,-0.00591,-0.06571,0.05434,-0.07427,0.05565,-0.00261,0.04483,-0.05564,-0.00337,-0.02237,0.05537,-0.03883,0.05504,0.05181,0.02832,0.01202,0.06473,-0.04428,0.10812,0.02078,-0.02119,0.00338,0.0198,-0.0151,-0.02498,0.07694,-0.05259,0.00156,0.01578,-0.00078,0.02696,0.00473,-0.06676,0.00883,-0.05098,-0.02722,0.00702,0.09047,0.03727,0.01448,0.04001,-0.04871,0.02023,0.02497,-0.01657,0.00813,0.02624,-0.00395,0.01977,0.03588,0.03788,0.00953,-0.07412,0.05215,0.01803,-0.03882,0.01444,-0.05967,-0.01346,0.01021,0.02523,0.00536,0.03825,0.04463,-0.00137,0.03381,-0.04065,-0.03129,-0.02109,0.06328,-0.0305,0.00533,-0.00164,0.0101,0.07412,-0.0058,-0.03469,0.03756,-0.00191,-0.00051,-0.03239,0.02762,0.00755,0.04789,-0.05378,0.04288,0.0157,-0.00389,-0.05751,-0.02263,-0.00821,0.03282,0.00684,0.02884,-0.0165,-0.00353,0.04453,-0.01518,0.04338,0.03077,-0.03573,-0.01228,-0.01598,-0.08233,0.03605,-0.00803,0.00965,0.01965,0.00078,-0.01005,0.01178,0.02582,0.04101,-0.04663,0.02875,-0.00897,0.0089,-0.01276,0.07294,-0.01645,-0.00289,0.07501,-0.00932,-0.06932,0.01767,0.03568,0.03718,0.03795,-0.04512,-0.07569,-0.00132,-0.01204,0.05256,-0.02646,0.05114,0.00829,0.05783,-0.02124,0.01854,-0.05682,0.03911,0.04302,-0.03339,-0.0295,-0.04067,0.0125,0.00941,-0.03783,-0.0452,-0.01747,-0.07736,-0.00984,-0.07439,-0.0596,0.01096,-0.01165,0.01364,-0.01642,-0.04504,-0.00074,-0.06264,0.05285,-0.04867,0.04893,0.00753,0.03185,-0.03017,0.0245,0.06587,0.01308,0.00762,-0.01778,-0.04827,-0.02221,-0.00528,-0.00278,0.0158,0.01166,-0.00209,-0.01503,-0.00423,0.00296,-0.0085,-0.01124,-0.00784,0.04966,-0.02474,0.01236,-0.04486,-0.08697,0.04521,0.00741,0.06508,0.00574,0.00414,0.06586,0.00426,0.02283,-0.04052,-0.02285,-0.00144,-0.00564,-0.06126,0.0179,0.03033,0.00422,0.01896,-0.00161,0.01376,-0.00106,-0.00172,0.02732,0.01586,-0.03544,-0.02341,0.03688,0.03816,-0.00515,0.00062,-0.01325,0.04487,-0.02591,-0.00964,-0.05607,-0.0558,-0.04139,0.02861,-0.04025,-0.00571,0.03346,0.02096,-0.00409,0.00398,-0.0056,0.03179,-0.00013,-0.02663,0.02464,-0.00337,-0.05947,-0.02891,0.03516,-0.00521,0.09652,0.02848,0.0157,0.02105,-0.02821,0.01941,-0.01618,-0.00767,0.00427,0.04608,0.01434,0.05955,0.01891,0.00037,-0.00765,0.00046,0.03361,0.04838,0.04097,-0.00928,-0.01247,0.00564,-0.01046,0.0573,-0.02248,-0.04278,-0.04444,0.00097,0.03561,-0.04539,0.04689,-0.0053,0.06255,0.04307,0.00979,-0.01437,-0.05835,-0.0086,-0.03667,-0.01422,0.01245,-0.00192,0.02025,-0.04064,-0.0598,0.02835,0.02484,-0.00483,-0.04993,-0.04576,-0.01561,0.02534,-0.01564,-0.01445,0.04872,0.07781,0.0105,0.0165,-0.03134,-0.03242,-0.00436,-0.03847,0.02312,0.02668,0.0736,-0.04639,-0.00617,-0.06392,0.03354,-0.01611,-0.00031,-0.00095,0.02145,0.01847,-0.00028,0.03254,0.01091,-0.02053,-0.05591,0.00242,0.04173,0.02442,0.00814,0.03328,0.00482,0.00152,-0.03654,0.02685,0.03023,0.00147,-0.00318,-0.05659,0.04384,0.02963,0.03299,0.01286,-0.01407,-0.02469,0.02737,0.00982,0.01018,-0.02574,-0.01238,-0.01018,0.03982,-0.00949,-0.02201,-0.05828,0.0278,-0.00344,-0.01763,-0.01028,0.05546,0.01633,0.02417,-0.06272,-0.06969,0.00854,0.00554,0.0073,0.042,-0.03513,-0.01708,0.02402,0.0215,0.0376,0.01705,-0.02001,-0.01269,-0.0035,0.03579,0.03565,0.03244,-0.01909,-0.06246,0.06439,0.04524,0.01203,-0.00372,0.02409,-0.02607,0.01242,0.06522,0.02326,-0.02054,-0.04659,0.04401,0.05683,-0.01585,-0.03586,0.0294,0.03101,-0.01007,0.00784,0.04637,0.02119,-0.05409,-0.05892,-0.02085,0.00315,0.06842,0.05378,-0.00965,-0.0297,-0.01016,-0.05048,0.04747,0.01638,-0.00996,0.08031,-0.05239,0.03871,0.00214,0.04031,0.03662,0.00641,0.02262,-0.01548,0.00742,0.01747,-0.05349,-0.00729,-0.0151,0.0102,0.03936,-0.04074,0.00664,0.06137,-0.04453,-0.01908,-0.00531,0.00752,-0.01547,0.00543,0.03029,-0.03933,-0.00281,-0.03652,-0.04028,-0.00176,-0.00765,0.05078,-0.02423,0.00838,0.0313,0.05346,0.01907,-0.01309,-0.02221,-0.01801,-0.05967,-0.05556,0.00934,0.00507,-0.0592,0.02398,0.01748,-0.02122,0.02222,0.00458,-0.02137,0.05241,-0.05776,-0.01238,0.01744,0.02485,-0.00142,0.02056,0.067,0.05828,-0.0605,0.05868,0.09186,-0.01932,0.01644,-0.02092,-0.01927,-0.0268,-0.02168,-0.077,-0.01403,-0.01338,-0.05007,0.04954,-0.05535,-0.01864,0.04049,-0.07197,-0.01352,0.0221,-0.0389,-0.06278,0.00405,-0.00175,-0.00652,-0.03533,-0.00081,0.01157,-0.01672,0.01829,0.01497,-0.00286,-0.0265,0.0126,-0.01149,-0.00538,0.00315,-0.03416,-0.01825,0.02264,-0.00929,-0.02449,0.01685,-0.03904,-0.01319,0.00672,0.0121,0.05151,0.02181,0.02631,0.01373,-0.00427,0.03773,0.0218,0.05186,0.00395,-0.09291,-0.01966,0.00513,0.03834,0.03701,-0.02071,0.03376,-0.02332,-0.04709,0.02869,-0.05841,0.02435,0.02955,-0.01287,-0.008,0.00285,0.00679,0.01563,-0.04398,-0.01411,0.00983,0.01121,

category;\n111","vector":[-0.01017,0.03716,-0.20135,-0.0425,0.03865,-0.04131,0.03465,0.00611,-0.0065,-0.0189,-0.01955,0.00335,0.09551,-0.00528,-0.04026,-0.05639,-0.04932,-0.07291,-0.00772,0.02851,-0.02199,-0.03738,-0.04946,-0.01751,0.06773,0.0157,-0.0559,-0.02317,-0.0595,0.02463,-0.04112,0.04525,-0.01513,-0.00284,-0.01671,-0.03006,0.00916,0.0098,0.00583,0.02011,0.0406,-0.0045,0.03287,-0.0462,0.07138,-0.05016,0.03708,-0.02068,0.07782,-0.02202,0.03694,-0.02614,0.03768,-0.01787,0.04346,0.04135,-0.03311,0.02333,0.04461,-0.04497,0.10574,0.06177,-0.00307,0.0248,0.02694,-0.04635,-0.02205,0.07226,-0.04567,-0.06328,-0.02398,-0.03799,0.05457,0.006,-0.05523,0.01166,-0.03853,-0.0301,0.02688,0.0452,0.03155,-0.0028,0.06131,-0.00764,0.01172,-0.01,-0.02361,0.00715,-0.00343,0.06408,0.00882,-0.0084,0.06319,0.0265,-0.04339,0.06684,0.00219,-0.03868,-0.02626,-0.08865,-0.02431,0.01539,0.04392,-0.01817,0.02158,0.04329,0.00901,0.03296,-0.0459,-0.00152,-0.04216,0.04149,-0.04325,0.01575,0.00907,-0.00673,0.08016,-0.01795,-0.01537,0.02726,-0.01639,-0.00163,-0.01468,0.05874,0.00269,0.03856,-0.0228,0.0361,0.03942,-0.04178,-0.05057,-0.02984,-0.01985,0.02684,0.01448,0.01949,-0.01539,-0.01633,0.04737,0.01719,0.05169,-0.00513,-0.02506,-0.04149,-0.0129,-0.04414,0.02203,-0.00583,-0.00252,0.01285,-0.01103,-0.00881,-0.01583,0.02023,0.07078,-0.03133,-0.00819,0.00625,0.02151,-0.02344,0.0472,-0.03785,-0.01789,0.08488,-0.01961,-0.0413,0.00659,0.0261,0.01193,0.04993,-0.02183,-0.04561,-0.01613,0.00913,0.00553,-0.04717,0.04259,-0.02162,0.05742,-0.01689,0.01685,-0.05429,0.06575,0.01548,-0.00504,-0.01157,-0.00628,-0.00032,-0.03957,-0.03453,-0.00294,0.03028,-0.05384,-0.02182,-0.07374,-0.07474,0.02909,-0.00846,0.0198,-0.01996,-0.01454,0.02122,-0.047,0.03168,-0.07123,0.0342,0.00014,0.03551,-0.01907,0.02333,0.07906,-0.00217,-0.02392,0.00401,-0.04781,-0.02543,-0.02931,-0.02014,-0.00477,0.04775,-0.00411,-0.00086,-0.02798,0.00139,0.01419,0.0025,-0.00623,0.02663,-0.0234,-0.00668,-0.03946,-0.10832,0.01444,-0.02394,0.0569,0.04196,0.00372,0.07886,0.03071,0.0383,0.00434,-0.01641,0.02373,-0.0397,-0.05695,0.00666,0.0141,0.00515,0.01068,0.02973,0.01325,-0.00917,0.02083,0.03816,-0.02403,-0.02538,-0.02867,0.02558,0.06851,-0.00421,0.00168,-0.00141,0.02975,-0.04324,-0.01004,-0.04961,-0.02976,-0.05383,0.00382,-0.02163,0.00786,0.00503,0.03048,0.01474,-0.01568,0.00846,0.04587,-0.00444,-0.02488,0.03047,-0.01275,-0.07632,-0.03411,0.03065,0.00027,0.04402,0.02384,0.02145,0.01623,-0.02365,0.03181,-0.02278,0.00291,0.04005,0.0412,0.01685,0.07104,-0.03989,-0.02115,-0.03847,0.00987,0.02248,0.0785,0.02161,-0.026,-0.03841,0.00278,0.01497,0.05798,-0.01871,-0.05362,-0.01965,-0.0112,0.01519,-0.01356,0.02431,0.01095,0.01634,0.05034,-0.00617,-0.00815,-0.06425,0.00909,-0.07575,-0.0081,0.05588,-0.0092,0.03165,-0.05654,-0.03169,0.04167,0.04652,-0.01538,-0.03975,-0.01864,0.01057,-0.00274,-0.02083,-0.00146,0.06245,0.06808,-0.0042,0.01183,-0.03141,-0.00747,0.007,-0.03568,0.01808,-0.01902,0.03281,-0.02458,-0.01391,-0.04025,-0.00292,0.00323,0.02504,-0.00293,0.05988,0.01841,0.01647,0.06937,0.04143,-0.00809,-0.04354,0.01539,0.06743,0.01078,0.01204,0.02463,-0.03143,-0.03717,-0.03876,0.02458,0.0257,0.01371,0.01606,-0.06642,0.02405,0.01771,0.01744,0.02166,-0.03154,-0.00946,0.00221,0.01389,0.02015,-0.02961,-0.06398,-0.01274,0.01376,-0.01876,-0.01435,-0.05571,0.0505,0.00147,-0.04449,-0.00691,0.03761,0.02694,0.04749,-0.05805,-0.06823,0.00751,0.0065,-0.01464,0.06254,-0.02846,-0.03343,0.04,0.0052,0.02062,0.01679,-0.02263,-0.02259,-0.01463,0.06788,0.04592,0.00749,-0.05648,-0.01262,0.03689,0.05671,0.01365,-0.02344,0.03779,0.00199,0.01142,0.03117,0.01095,-0.04762,-0.01124,0.05382,0.03363,-0.03051,-0.00743,0.02717,0.04918,0.02199,0.03429,0.04078,0.04362,-0.04064,-0.06792,-0.01432,0.01335,0.10236,0.00408,-0.00379,-0.02916,0.02136,-0.00287,0.03887,0.02319,-0.02292,0.0602,-0.06354,0.03674,-0.01556,0.01176,0.04004,0.01467,0.01566,-0.03102,0.02364,0.02883,-0.03311,0.0148,0.00749,-0.00493,0.05859,-0.01654,-0.02643,0.03152,-0.04811,-0.0237,0.01764,0.00429,-0.03415,0.02133,0.0421,-0.03294,0.02155,-0.05053,-0.03369,0.0145,-0.00091,0.04191,-0.03954,0.03149,0.02907,0.03147,0.0363,-0.01504,-0.04636,-0.01572,-0.02133,-0.02061,0.00193,0.03152,-0.00363,0.0063,0.04315,-0.01171,0.01509,0.03749,-0.0212,0.08371,-0.01703,-0.02255,0.00045,-0.00961,0.01146,0.0344,0.07011,0.05036,-0.05926,0.05443,0.06685,-0.03103,0.0176,-0.00775,-0.03547,0.00297,0.00777,-0.06977,-0.00588,-0.00552,-0.03108,0.05254,-0.02421,-0.0241,0.004,-0.06868,-0.01074,0.02244,0.00013,-0.04592,0.02802,0.02361,0.00586,-0.04114,0.03225,0.0248,-0.02133,0.04359,-0.01414,-0.02072,-0.03068,0.01912,-0.01272,0.02105,-0.01343,-0.0091,-0.00176,-0.00801,-0.03089,-0.00427,0.01209,-0.04134,-0.00383,0.03431,-0.00934,0.06072,0.02992,0.0219,-0.02124,0.02402,0.01086,0.0064,0.0049,0.00834,-0.11048,-0.00639,-0.00701,0.02698,0.01731,-0.0121,0.00184,-0.05185,-0.03875,0.02582,-0.07063,0.02635,0.04882,-0.00702,-0.02178,-0.00968,0.00849,-0.02206,-0.03453,-0.03068,0.02744,0.00985,-0.00805,-0

of input types, from text\nboxes and text areas to checkboxes, radio buttons, and more.\nText boxes:\nText boxes accept a wide range of alphanumeric, text and other characters in a single line box.\nThe general format of a text box input is as follows:\n<input type=\"text\" name=\"name\" size=\"size\" maxlength=\"length\" value=\"value\">\nThe size attribute specifies the width of the box (in characters of the current font) as it should\nappear on the screen, and maxlength specifies the maximum number of characters that a user is\nallowed to enter into the field.\nText Areas:\nWhen you need to accept input of more than a short line of text, use a text area. This is similar to\na text box. But, as it allows multiple lines, it has some different attributes.

user.\n116","vector":[0.00298,0.00288,-0.17361,-0.03313,0.08477,-0.04622,0.03151,-0.01289,0.03161,-0.05433,-0.02836,0.0003,0.09847,-0.01011,0.0046,-0.04561,-0.00238,-0.10726,-0.01869,0.02256,-0.03679,-0.05217,-0.04449,0.01421,0.06054,-0.0119,-0.0247,-0.02592,-0.05335,0.01195,-0.05422,-0.00205,0.03159,0.00151,-0.02248,-0.03254,-0.02251,0.01119,-0.02843,-0.01324,-0.0075,-0.01371,-0.00105,-0.00364,0.02299,-0.048,0.04812,-0.04801,0.02548,-0.00347,0.00729,-0.06327,0.02324,-0.06086,0.09803,0.02722,-0.0476,0.03439,0.02386,-0.02834,0.10385,0.076,-0.02315,0.0707,0.0612,-0.01476,-0.05948,0.04665,-0.05398,-0.0134,0.00666,0.02644,0.00783,0.01488,-0.0133,0.02838,-0.04761,-0.03406,-0.00207,0.0185,0.03628,-0.02216,0.06146,-0.06109,0.03124,-0.00992,-0.00595,0.01882,-0.0237,0.03989,-0.02108,-0.02589,0.0381,0.00897,-0.0675,0.03624,-0.02627,-0.00863,-0.03308,-0.04441,-0.03211,0.0144,0.01521,0.00893,-0.00537,0.04701,0.02078,0.00577,-0.01272,0.00448,-0.05319,0.03473,-0.02981,0.02488,-0.00425,-0.05183,0.07782,-0.0479,-0.00244,0.01299,-0.0091,-0.03701,0.01182,0.04394,0.02512,0.04487,-0.00114,0.00814,-0.00124,-0.03333,-0.04281,-0.03602,-0.07132,-0.01385,0.04852,0.01179,-0.0223,-0.03029,0.027,0.05244,0.05851,0.00228,-0.0249,-0.06076,-0.02579,-0.0042,0.05146,0.02337,0.02846,-0.00717,0.00128,0.02797,0.00965,0.00905,0.02466,-0.05558,-0.00813,-0.01008,0.03733,0.00465,0.08106,0.00049,-0.0086,0.05161,-0.02766,-0.06755,0.01722,0.03642,0.00551,0.03699,-0.00443,-0.01465,-0.00347,-0.00251,0.004,-0.01981,0.01922,-0.05611,0.05279,0.00594,0.00938,-0.06489,0.05031,0.00798,0.01176,-0.01658,0.0442,-0.01642,-0.06196,-0.08361,-0.03686,-0.00165,-0.04084,-0.00546,-0.06155,-0.04161,0.04905,-0.0052,0.01564,-0.016,-0.01204,0.05053,-0.02602,0.01632,-0.05337,0.0471,0.00438,0.04571,-0.02495,0.05291,0.09483,-0.03705,-0.03946,0.01833,-0.03898,0.01099,-0.01238,-0.01283,0.00607,0.00255,0.02695,0.00316,0.01289,-0.03582,-0.00087,0.01886,0.00082,0.02479,-0.0299,0.01075,0.00022,-0.09335,0.02046,0.00695,0.04277,0.0463,-0.00089,0.05453,0.00331,-0.03703,0.01062,-0.01708,0.04337,-0.00785,-0.05087,0.0198,0.00861,-0.0163,0.00813,0.05423,0.04314,-0.01684,0.02308,0.00884,-0.03232,-0.00214,-0.00453,0.0003,0.01749,-0.01068,0.00564,-0.0036,0.0148,-0.02245,-0.0243,-0.06271,-0.00053,-0.00209,0.01271,-0.00453,-0.0227,0.02588,0.00277,0.0228,0.01391,0.01524,0.02997,-0.0284,-0.02225,0.02684,-0.01593,-0.05223,-0.03577,0.00682,0.00969,0.05357,0.02627,0.04506,-0.03714,0.0062,0.00669,-0.01105,-0.05194,0.02181,0.00678,0.02807,0.07422,-0.04628,0.01546,-0.07454,-0.00846,0.05199,0.03892,-0.00618,-4e-05,-0.02066,0.03519,0.01157,0.04664,0.02663,-0.05302,-0.01331,-0.03069,0.02815,-0.05232,0.03577,-0.00129,0.03392,0.03289,-0.02469,-0.01587,-0.05825,0.00379,-0.02085,0.01072,0.05538,-0.02889,0.02179,-0.04115,-0.0306,0.02479,0.03687,-0.02887,-0.04202,-0.01078,0.0037,0.00144,0.00323,0.0046,0.05432,0.0732,-0.03659,0.01574,-0.03754,-0.00035,-0.02558,-0.02548,-0.01345,0.00958,0.04226,-0.00609,0.04704,-0.02442,0.00615,0.00156,0.03123,0.00802,0.03895,0.01548,0.02182,0.03057,0.03041,0.03633,-0.02354,0.01683,0.06149,0.0105,0.00987,0.02698,-0.00057,-0.01702,-0.06283,0.00155,-0.01895,0.03233,0.01591,-0.0691,-0.02939,-0.04698,0.03458,0.03604,-0.01481,0.01853,0.00574,-0.01659,-0.02306,-0.02541,0.0074,0.01528,0.01319,-0.03048,-0.04491,-0.05062,0.00927,0.03591,-0.00643,-0.01553,0.03539,0.04226,0.04944,-0.05721,-0.04281,-0.0203,-0.0173,0.01575,0.05209,-0.01408,-0.02839,0.06719,-0.03778,0.02232,0.01693,-0.03508,-0.01576,0.01479,0.03282,0.02239,-0.0052,-0.03362,-0.02135,0.03694,0.04907,0.03979,-0.0072,0.05846,0.00522,0.00509,0.02177,0.03555,-0.05632,-0.01854,0.05401,0.02521,-0.03507,-0.03649,0.03829,0.01008,0.00101,0.04374,0.07181,0.03737,-0.04261,0.00417,-0.03169,0.01174,0.08771,0.00527,-0.01499,-0.02497,0.01736,-0.04456,0.01487,0.0519,-0.03509,0.05051,-0.01522,0.00994,0.01832,0.02129,0.0462,-0.00386,0.02284,-0.08054,0.01389,0.02593,-0.04785,0.00553,-0.02641,0.0264,0.06484,-0.01404,-0.02541,0.05752,0.01461,0.01015,0.033,0.01048,-0.03181,0.04413,0.01149,-0.01127,0.03431,-0.0349,-0.01635,0.01134,-0.00491,0.04939,0.0004,0.06912,0.04734,0.02449,0.0288,-0.00885,-0.02879,-0.00238,-0.01136,-0.05219,-0.01718,0.00726,-0.01895,0.0009,0.0042,-0.01826,0.0315,0.03036,-0.02743,0.05507,-0.04565,-0.02591,-0.04193,-0.00964,-0.01522,0.05347,0.03818,0.06013,-0.05009,0.0444,0.08725,-0.03481,0.06244,0.01955,-0.01145,-0.00144,0.00305,-0.05667,0.00661,-0.02587,-0.04236,0.06829,0.02487,-0.00218,0.06891,-0.04606,-0.01658,0.00636,-0.02144,-0.04004,0.0513,0.00754,-0.00673,0.01473,0.02115,-0.00458,-0.02602,0.0776,-0.03426,0.01105,-0.03011,0.01648,-0.01436,0.01865,-0.01392,-0.04271,-0.01975,0.03233,-0.02789,-0.03339,-0.00637,-0.02776,-0.0271,0.04756,0.04795,0.04096,0.01312,0.02563,-0.037,0.00523,-0.00147,-0.01543,0.02345,0.01802,-0.0902,0.01577,-0.00748,-0.01801,0.00483,0.01818,-0.01515,-0.06305,-0.00918,0.03384,-0.07444,0.01902,0.0532,0.00146,-0.02119,-0.01175,-0.00548,-0.02027,-0.0195,-0.05767,0.06559,-0.02074,-0.01125,-0.00325,0.03515,-0

Write a simple number - guessing game in PHP. The script should “think” of a random\nnumber between 1 and 100, then give the user five chances to guess the number. For each\nguess, the script should report whether the guessed number was too low, too high, or\ncorrect. (Hint: Use rand (1, 100) to generate a random number between 1 and 100.)\nCreate a php script that displays a form allowing the user to select one of three Amazon\nstores - amazon.com, amazon.ca, and amazon.co.uk — and then jumps to the relevant\nstore based on the user’ s choice.\nDesign a php script to display the health suggestions for user based on the Body Mass\nIndex (BMI) value.

13 Resource Book","heading":"Competency Level 12.1: Explores the role of ICT in the world of business","page":136,"text":"Use of ICT in business functions as information systems could be broadly classified into two\ncategories; transaction processing and decision support. Transactions are elementary activities\nbeing recorded in organizations. For example, a sale taking place at a supermarket is a\ntransaction. Similarly, a new delivery of stocks, recruitment of a new employee, a cash\nwithdrawal at an ATM by a customer, a book borrowed at a library and a new item manufactured\nat a factory are examples for transactions. Every business function needs information systems to\nrecord such transactions for future use. Typically, transaction processing systems help keeping\ntrack of such transactions in business functions. On the other hand, managers need information\nsystems to help them to make decisions.

concerned with\nthe planning and control of all those activities that transform inputs into outputs by adding\nsome value to inputs. For example, in a soft drinks production plant, inputs such as sugar,\nflavors, water, etc. will be converted into soft drinks and come out in containers (bottles) as\nthe output. In such a plant, the managers have to plan what to produce, when, in what\nquantities and where to distribute. If they produce the wrong product, that will be rejected\nby the consumers. If they produce more, excess stock will be remaining in the warehouses.\nIf they produce less, there will be shortages in the market. This will make the consumers\nunhappy.

hearts of the\ncustomers. All companies try to make the right product available to customers through the\nright channel at the right price. Therefore, all successful firms attempt to understand their\ncustomers better and try to keep them satisfied and loyal to the company. ICT provides\nmeans for companies to understand their customers by segmenting them based on purchase\ndata, knowing what items are usually bought together and also by predicting who will buy\nwhat, when and where.

partners such as\nraw material suppliers, logistic companies and distributors. However, if the activities of\nthese partners are not synchronized with the production activities of the firm, the end\nproducts cannot be successfully offered to the market. ICT-based supply chain management\nsystems9 play a critical role here by automating the flow of information across\norganizational boundaries and thereby linking external actors in the supply chain with the\nfirm.

13 Resource Book","heading":"Competency Level 12.2 Analyses the relationship between ICT and business operations","page":143,"text":"ICT has also contributed largely to creating more secure and alternative payment mechanisms for\nbusiness transactions. Especially in electronic commerce, several alternative payment\nmechanisms are preferred over traditional cash-based payment methods such as cash on delivery\n(COD). One of the key ICT-based developments in payment mechanisms is the payment\ngateways which enable payments using credit/debit cards. A payment gateway is a software\nservice that securely handles the credit card information exchange and verification in order to\ncomplete an electronic commerce transaction. Once the customer authenticated a credit card\npayment for an online purchase he/she wishes to proceed, the merchant’s webserver securely\ncollects the credit card details (in encrypted format) from the customer’s browser and sends the\ndetails of the payment to its payment gateway.

The payment gateway directs the details to the\npayment processor of the merchant’s bank through which the details will be sent to the relevant\ncard association (Visa, MasterCard, etc.) The card association directs the details to the card-\nissuing bank which responses with an accept/reject message after a verification process. The\nprocessor forwards the response to the payment gateway to be interpreted at the merchant’s\nwebsite. If accepted, the transaction gets completed and the customer gets a confirmation\nmessage, whereas if rejected, the transaction gets aborted delivering a failure message to the\ncustomer.

is the customer has to submit credit card\ndetails to every merchant (or rather at every merchant’s web site) that they shop with. This\nincreases the number of chances of getting your sensitive data being recorded by one of those\nmerchants. There are third party systems such as PayPal that reduces this risk by mediating the\npayment process and allow sending and receiving money more securely. In the case of PayPal,\nboth buyers and sellers can register with PayPal using a valid email address and link any number\nof bank accounts and credit cards to that. Buyers can then shop securely with sellers who allow\npayment with PayPal (usually those who have the ‘Checkout with PayPal’ option).

Even the modern fictions such as ‘2001: A Space Odyssey’\nby Sir Arthur C Clarke as well as the famous 80’s tele series ‘Knight Rider’ had machines that\nexhibit not only intelligent but also some emotional characteristics. For example, KITT, the\nintelligent car in Knight Rider, engages in several conversations with its master Michael Knight\nthat shows some emotions. On the other hand, humans, throughout history, have attempted to\nbuild self-operating machines as well as machines with control mechanisms designed to\nautomatically follow a predetermined sequence of operations, or respond to predetermined\ninstructions. Those machines are known as automatons. However, the growth of such attempts\nto build truly intelligent machines had been very slow until the discipline of artificial intelligence\nwas formally begun in the mid-20th century.

There, a group of researchers\ninterested in thinking machines did an extended brainstorming session to elicit innovative ideas\non creating such machines. Since then, various definitions of artificial intelligence have been\nproposed by scientists.

In general, the intelligence demonstrated by machines so far is considered only as\nimitating human (or natural) intelligence. This could be well explained by the two hypotheses\npresented by John Searle in 1980. According to Searle, artificial intelligence has two forms;\nstrong form and the weak form.\n- Artificial intelligence, strong form: an AI system can think and have a mind\n- Artificial intelligence, weak form: an AI system can only pretend it thinks and has a\nmind\nThus, in order to create a truly intelligent and emotional machine, one must focus on the strong\nform of artificial intelligence. The researchers in the field of Artificial General Intelligence\n(AGI) are working on the creation of such machines (or computer systems) which are capable of\nworking in multiple fields.

As mentioned before Cortana in Windows as\nwell as Siri on Apple iOS systems are good examples for software agents that are practically\nimplemented. Such virtual assistants could be seen in many computer systems to make the tasks\nof the human users easier. Agents also assist humans in banking, e-learning, e-commerce,\nbooking, and in various other similar systems. For example, information searching in electronic\ncommerce applications involves a multi-agent system similar to the architecture depicted in\nFigure 5.4. There, the users submit their search criteria for products to an interface agent. The\ninterface agent then connects with an information broker agent who filters information received\nthrough agents at various merchants’ websites in response to the users’ search criteria to provide\nthe relevant information to the users.

As depicted in Figure 5.5, it\nprovides a simpler architecture to design computer systems. However, as the demand for\ncomputational resources rapidly grows, the von Neumann computer has now been pushed to its\nextreme limits of capabilities. According to Moore’s law, the processing speed of\nmicroprocessors doubles once every 18 months.

In the traditional approach, information is represented using a\nbinary system which has only two states (0 and 1). However, quantum computers which are\nbased on quantum physics, can represent information using multiple states.
