Today, often mistaken for the entire computer, case and all. CPU is NOT the entire computer but is the Central Processing Unit. It is the brain of computer executing tasks and telling the other components what to do. Mainly manufactured by AMD and Intel. the speed of the processor is measured in GHZ or MHZ (Gigahertz & Megahertz) for now anyway.
I recently upgraded my computers CPU from and AMD 2500+ (~1.8ghz)to a pentium IV 3.0 GHZ processor but I didn't notice much of a diffrence until I got some more RAM.

A CPU is basically the brains of your computer. Without a CPU, your computer would be an expensive paperweight.

1. Central Processing Unit. The main part of your computer, (not your monitor or sound card, for example).
2. Cayce Pollard Units. From William Gibson's science fiction novel Pattern Recognition, non-brand-identifiable clothing: "things that could have been worn, to a general lack of comment, during any year between 1945 and 2000."
