Decimal Number     It uses digits from 0 to 9 for representing the numbers. It is represented with base 10. A decimal number can be represented using positional weights. Example: (198)10 = 1 X 102 + 9 X 101 + 8 X 100 4

Binary Number     It consists of only two digits, 0 and 1. It is represented with base 2. A binary number can be represented using positional weights. Example: (198)10 = (11000110)2 = 1 X 27 + 1 X 26 + 0 X 25 + 0 X 24 + 0 X 23 + 1 X 22 + 1 X 2 1 + 0 X 20 = 128 + 64 + 0 + 0 + 0 + 4 + 2 + 0 = 198 5
