A hexadecimal number is a base-16 numeral system that uses sixteen distinct symbols to represent values. The symbols include the digits 0-9, which represent values zero to nine, and the letters A-F (or a-f), which represent values ten to fifteen.
For example:

FFrepresents the decimal value255(15 * 16^1 + 15 * 16^0).
Hexadecimal is commonly used in computing and digital electronics because it can represent large binary numbers in a more compact and readable form. Each hexadecimal digit corresponds to four binary digits (bits).
