Kelly,

Cisco has split its CCNA certification into two exams to make it more
palatable to beginners and to break the exam into smaller chunks (and maybe
to sell more books.) They have a network fundamentals book that would be
great for you. This explains routers and switches as well as subnetting and
network setup without getting too much into the specific Cisco commands and
methods.

Go onto Amazon or Half.com and grab one of those for cheap.
