HEX Short for hexadecimal refers to the base-
16 number
system, which consists of 16 unique symbols: th e
numbers 0 to 9 and the letters A to F. For example, the
decimal number 15 is represented as F in the
hexadecimal numb
ering system. The hexadecimal
system is useful because it can r epresent every byte (8
bits) as two consecutive hexadecimal digits. It is easier
for humans to read hexadecimal numbers than binary
numbers.
