Abbreviated hex. The base-16 numbering system that uses the digits 0 through 9, followed by the letters A through F, which are equivalent to the decimal numbers 10 through 15. Hex is a convenient way to represent the binary numbers that computers use internally because it fits neatly into the 8-bit byte. All the 16 hex digits 0 through F can be represented in 4 bits, and 2 hex digits (1 digit for each set of 4 bits) can be stored in a single byte. This means that 1 byte can contain any one of 256 different hex numbers, from 0 through FF.
   See also binary; decimal.
