OBJECTIVES 1. Be able to recognise binary code 2. Be able to convert denary numbers into binary numbers 3. Be able to convert binary into denary numbers
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)
