AMD Phenom x4 955 Black Edition AM3 Review
 

There are many essential components to every computer – some perhaps are less important i.e. sound cards etc – but most are vital.

But it is more than that, it is the component which performs programmed instructions, performs arithmetic and controls data input/output functions.
