A Little frustrated with TCP/IP Protocols and Their Functions
I'm a little frustrated. It seems everywhere I look they are named differently or grouped differently. Example...I've seen Layer 1 referred to as the Network Access Layer...Network Interface Layer.. Physical Layer...Hardware Layer...and Link and Physical Layer..etc. Same at level 2.. Data Link Layer... Internet Layer...IP Layer....and so on for each layer. I understand I need to understand the layers and what functions happen at each layer but it's kind of throwing me. It seems like there are several excepted ways to refer to it. What I need to know is what is the Network+ test gonna call for? Anyone else having this problem. I mean...I understand it and whats happening..but it seems like the correct answer is gonna depend on who's asking??
