The systemic methods which, are used to represent numbers, are known as numbering systems. We have the following numbering systems:

  • Binary
  • Octal
  • Decimal
  • Hexadecimal

The binary number system

A machine can only understand two states: ON (represented by 1) and OFF (represented by 0). This effectively means that any input given to the computer must be in the form of 0 and 1’s. The binary number system uses two digits, 0 and 1, to represent a number. Since it has only two digits, the base of the binary number system is 2.
