CPU
Central Processing Unit

The CPU, or Central Processing Unit, is also commonly called the processor, or the microprocessor. The CPU is the brain of the computer. It's job is to process data and to interpret instructions. The quality (speed) of the processor determines how fast the system will run.

The processor is the most expensive component in a computer, with price being determined primarily by speed and efficiency. There are two popular manufacturers, AMC and Intel.

Note: The term CPU is sometimes used to refer to the computer case.  This is incorrect.  The CPU is a component within the case, it is not the case. Try to avoid this error.
