CPU

CPU

Expanded = (Central Processing Unit)

This is arguably the single most important component of a PC.

It is a thin square chip which is seated firmly on your Motherboard.

It is invariably covered by a large metal heat-sink ( A black thing with fins on it ) and in later models sometimes a fan to cool it.

The CPU controls and co‐ordinates the actions of the entire PC following instruction from the installed software.

It ‘s role is to determine which hardware component does what, It then assigns tasks and also undertakes complex calculations which are then relayed through the various relevant components and back again to the CPU.

Some people liken it the CPU to the brain.
