HEX / Hexadecimal


Hexadecimal, or 'Hex' for short is a numbering system using base 16 (as opposed to the usual base 10). Hex is a useful way to express binary computer numbers in which a byte is normally expressed as having 8 bits; with 2 hex characters representing eight binary digits - aka a byte.

'Hex' is word, sometimes used by 'techies' to throw ordinary users off the scent; invariably it only clouds the issue!
