  • Each digit that is 0 or 1 in a binary number system is also known as bits.
  • As it contains 2 digits, the base value of binary system is 2.

Decimal numbers:

  • A decimal system consists of numbers from 0 to 9.
  • Using a sequence of one or more digits, a decimal number can be represented.
  • As it contains 10 digits, the base value of a decimal number system is 10.

Octal numbers:

  • An octal number system consists of numbers from 0 to 7.
  • A machine code generally contains binary digits that can be represented in bits and are very large to handle in operating system.
  • As it contains 8 binary digits, base value of an octal number system is 8.
  • By grouping consecutive binary digits into three groups starting from the right, octal numbers can be made from binary numbers.
