A Computer is ran by a CPU (Central processing unit), it’s kind of like the computer’s brain. The CPU has lots of little switches in it that can either be ON (a 1) or OFF (a 0)

Denary (our numbers) Binary

To make the number 5, place a 1 under the numbers that you need and a 0 under the numbers that you don’t… Denary numbers – keep doubling! This is Binary
