The binary number system was introduced by an Indian-scholar Pingala in around 5th -2nd centuries in BC.
- A binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" (zero) and "1" (one).
- The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit.Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices.
- Every digit in a binary number is raised to the powers of 2, starting from the rightmost with 20. In the binary system, each binary digit refers to 1 bit.
