What Is Binary Number System? |
|
Answer» Every NUMBER system uses positional notation, i.e., each position in which a digit is written has a different positional value. Each position is power of the base, which is 2 for binary number system, and these POWERS begin at 0 and increase by 1. The value of a binary number is BASED on the presence of 1 bits and their positional value. So, the value of a given binary number is: 1 + 2 + 4 + 8 +16 + 32 + 64 + 128 = 255 which is same as 28 - 1.
