Base-16 numbering system
Communicating base-2 numbers is difficult for human because of all zero’s and one’s. To make it easier to
present computer data, hexadecimal or base-16 numbering system is used. Four digit of base-2 numbering
system convert to one digit of base-16 numbering system. Since we did not have digits for 10, 11, 12, 13, 14
and 15, they were assigned letters A, B, C, D, E and F respectively.
