create a Comptia Security + Knowlage checklist page which is designed to be printable. It should cover basic linux CLI commands, What a MAC address is and how it gets traffic to the next hop, What an IP address is and how every computer has one, What ports are and how every service the computer provides will listen on a port. Include a diagram of the TCP/IP stack with an description next to some fake addresses. for example "Layer 2 : Addressed to the next hop, in this case the default gateway. Layer 3 : addressed to the web sites IP address. Layer 4 : Addressed to the port the web server is listening on. Layer 7 : a message the web server will understand asking for the main page of the site." use diagrams and examples where appropriate.
