I'm going to expand on this. Not all of this directly pertains directly to football, but it comes up a lot and can be useful to know.

First, there is the National Collegiate Athletic Association (NCAA), which is pretty much what it sounds like. They make the rules and poo poo for "amateur" college sports, and throw the hammer down on USC when they do bad things.

There are three divisions: DI, DII, and DIII. There are qualifications for each divisions based on number of sports fielded, athletic scholarships granted, and a bunch of other stuff. To make it easy, DI is the big boys. In the late 70s, DI was further split into DI-A and DI-AA based on the status of the football program (number of scholarship players, attendance numbers, etc.) Again, DI-A is the big boys.

A couple years ago, DI-A and DI-AA were renamed Football Subdivision (FBS) and Football Championship subdivision (FCS), respectively. FBS has bowl games at the end of the season, FCS as a playoff.

Outside of NCAA classification, the conferences in FBS are further differentiated into BCS auto-bid (ACC, Big 12, Big East, Big Ten, Pac-10, SEC) and non-auto-bid (C-USA, MAC, MWC, Sun Belt, WAC) conferences. This pretty much splits teams into the haves and have-nots of the college football world.
