Binary number system

Binary number systems are those number system which uses two-digit 0 and 1 and their base is “2”. The base 2 of a binary number system is known as a “Positional Notation System”. Each digit is known as bit. In a binary number system, the instructions are carried through an electrical signal which is represented by electromechanical devices with two states “ON” or “OFF”

decimal number system

octal number system

An octal number system is a system that uses the digit 0 to 7(0,1,2,3,4,5,6,7) to represent the numbers and their base is “8”. The next digit of the octal number system is represented by numbers are 10,11,12,13,14,15,16,17. In this system, the base can be written as 8.

hexadecimal number system

In hexadecimal number it uses 16 digits in which it has both numeric and alphanumeric digits and it ranges between 0 to 9(0,1,2,3,4,5,6,7,8) and A to F(a,b,c,d,e,f) and it base is “16”.
