Binary - Base 2

Binary is a system used by digital devices like computers, cd players etc. It is a sequence of 1s and 0s which relate to on and off electrical pulses and can only have 2 states on and off unlike analogue systems which can have varying states. These 1s and 0s are commonly referred to as a bit (Binary Digit).

Mathematically binary is Base 2 unlike our counting system (decimal) which is Base 10.
