Binary is a base 2 number system invented by Gottfried Leibniz where numeric values are represented by different combinations of 0 and 1, also known as OFF or ON.

Why do computers use binary?

  • Binary is still the primary language for computers because of the following reasons.
  • It is a simple and elegant design.
  • Binary’s 0 and 1 method is efficient at detecting an electrical signal’s off or on state.
  • The positive and negative poles magnetic media is quickly translated into binary.
  • Binary is the most efficient way to control logic circuits.
