Binary Number System (Base 2)

We now come to a different number system – the Binary number system. This binary number system has a base of two, and the symbols used are “0” and “1”. In this number system, as we move to the left the value of the digit will be two times greater than its predecessor. Thus the value of the places are :

64 <= 32 <= 16 <= 8 <= 4 <= 2 <= 1
