Modern processors have two bus types: the front-side bus and the back-side bus. The back-side bus is where your cache memory lives. Cache is a very small amount of very fast memory--just a couple of megabytes. It's on a separate bus because if the CPU was making cache requests along the same bus as it was making main-memory requests, it would slow the cache down so much that having it would be pointless. It's as small as it is because (1) it's expensive as hell, (2) it generates a lot of heat, and (3) nowadays, they put a lot of it in the processor itself and they don't want the processor to be the size of a Buick.
The front-side bus is where your main memory lives. (This is also the bus the computer uses to talk to the video card, hard drive, modem and all the other things your computer is running, but that's not important now.) You know when you look at a computer ad, it says "This computer has 512MB RAM!" That's main memory. It's sitting on the front-side bus. And the faster that bus runs (it hasn't run at processor speed in decades) the faster your memory calls run and the faster your computer goes. Fast is good. The bus is rated in megahertz, same as your computer used to be before they started selling GHz PCs, and 800MHz is a very fast one.
