Binary Number

The binary number system is one of the four types of number systems. Binary numbers are represented in computer applications by only two symbols or digits, namely 0 (zero) and 1. (one). The binary numbers here are demonstrated in the base-2 numeral system. (101)2 is an example of a binary number. In this system, each digit is referred to as a bit. 

A binary number is defined in digital electronics and mathematics as a number conveyed in the binary system or base 2 numeral system. It denotes numerical values with two distinct symbols: 1 (one) and 0. (zero). The base-2 system is a positional notation that uses 2 as a radix.

A binary number is made up of several bits. Here are some examples:

  • 10101 is a binary five-bit number.
  • 101 is a binary three-bit number.
  • A six-bit binary number is 100001.
