 * __Binary:__

__Denary/Decimal:__ A numbering system of base 10, therefore may only take the values 0,1,2,3,4,5,6,7,8,9

__Hexadecimal:__ A numbering system of base 16, therefore may only take the values 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F || || [|Defintion of a byte] [|Definition of a bit] [|Definition of Binary] [|Definition of Hexadecimal]
