BINARY NUMBERS

BINARY NUMBER

A binary number system is one of the four types of number system. In computer applications, where binary numbers are represented by only two symbols or digits, i.e. 0 (zero) and 1(one). The binary numbers here are expressed in the base-2 numeral system. For example, (101)2 is a binary number. Each digit in this system is said to be a bit.

According to digital electronics and mathematics, a binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero). The base-2 system is the positional notation with 2 as a radix.

What is Bit in Binary Number?

A single binary digit is called a “Bit”. A binary number consists of several bits. Examples are:

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