All the calculation by computer is performed in base 2. Base 2 is also named as binary computation and it is used in all the computer and digital data processing processors.
Some differences between base 2 and base 10 are:
Base 2 number system contains 0 and 1 whereas base 10 is from 0 to 9.
Digital systems works on 0 and 1 logic i.e on and off logic. So we use digital system easily in binary domain whereas, decimal system has 0-9 levels and they are hard to be catered in digital domain.
Base 10 is used in normal calculations for daily use and binary is only confined to digital domain.
