Main
Imagine you're back in Primary School and you're looking at numbers. You would probably be looking at Hundreds, Tens and Units - this is known as the denary system - base 10. The denary system uses the numbers 0-9.

Computers ONLY understand the numbers 1 and 0 - this relates to electric charges that are either ON (1) or OFF (0). 

Therefore, when working with computers we must understand the Binary system - base 2.

Red Task
