What is Binary?

Binary is a number system that only uses two digits: 1 and 0.

 All information that is processed by a computer is in the form of a sequence of 1s and 0s. Therefore, all data that we want a computer to process needs to be converted into binary.

The binary system is known as a ‘base 2’ system. This is because:

* there are only two digits to select from (1 and 0) when using the binary system,

* data is converted using the power of two.
