Parts of a Computer
A Computer Has Many Parts
Just like your body has eyes, hands, and a brain, a computer also has different parts. Each part has its own special job. All the parts work together to make the computer useful.

The CPU Is the Brain
The CPU stands for Central Processing Unit. It sits inside the big box called the system unit. The CPU reads your instructions and carries out every action you ask for.
