A number system is used to express the numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner. There are four types of number system:
  1. Binary: It has base of \(2\) and consists two digits family of \((0,1)\text{.}\)
    🔗
    🔗
  2. Decimal: It has base of \(10\) and consists ten digits family of \((0,1, 2,3,4,5,6,7,8,9)\text{.}\)

    🔗
  3. Octal: It has base of \(8\) and consists eight digits family of \((0,1, 2,3,4,5,6,7)\text{.}\)

    🔗
  4. Hexadecimal: It has base of \(16\) and consists sixteen digits and symbols family of \((0,1, 2,3,4,5,6,7,8,9, A, B,C,D,E,F)\text{.}\)
