Hexadecimal (also base 16, or hex) is the base-16 positional numeral system, using the 16 symbols 0–9 and A‒F.

Hexadecimal (also base 16, or hex) is a numeral system with a base of 16. It uses sixteen distinct symbols, most often the symbols 0–9 to represent values zero to nine, and A, B, C, D, E, F (or alternatively a–f) to represent values ten to fifteen.

Each hexadecimal digit represents four binary digits (bits), and the primary use of hexadecimal notation is a human-friendly representation of binary-coded values in computing and digital electronics. More information may be found here.
