Hexadecimal (HEX) is a 16 base system used to simplify binary. Hex can be any of the 16 digits: 1 2 3 4 5 6 7 8 9 A B C D E F

This means an 8-bit binary number can be written using only two different hex digits - one hex digit for each nibble (or group of 4-bits). It is much easier to write numbers as hex than to write them as binary numbers.

11010100 in binary would be D4 in hex

FFFF3 in hex would be 11111111111111110011 in binary
