Binary Code

What is Binary?

• Binary is nothing more than a System of Counting

• Everything in a computer’s brain comes down 0’s & 1’s

• Binary existed before computers

• Binary is an ON or OFF counting system, all or nothing. ‘1’ represents ON, ‘0’ represents OFF.

• Because each digit in binary can have 2 values, the base is 2 (see the example below for clarification)

1. Below is an 8 digit binary number
