Hexadecimal notation is a numbering system that uses a base (radix) of 16. Unlike decimal notation (base 10) or binary notation (base 2), uses 16 digits: 0,1,2,3, 4, 5, 6, 7,8, 9, A, B, C, D, E, and F. Programmers use as a convenient way to represent binary notation, which is difficult to read and prone to error when manipulated by humans. The two notational systems are easily translated into one another because 16 is a power of 2. In contrast, decimal numbers are more difficult to translate into binary numbers because they are in base 10, and they are not a power of 2. So also each hexadecimal number can represent 16 quantities, a single hexadecimal number can stand for four binary digits (for example, 1111 [15 in decimal] = F [hexadecimal]). See binary notation, byte, decimal notation, octal notation.
