Hex

Hex, short for hexadecimal, is a number system that uses 16 symbols: 0-9 to represent values zero through nine, and A-F to represent ten through fifteen. It's commonly used in computing because it simplifies how computers encode and read data, such as colors in digital design or memory addresses. Unlike the familiar decimal system (base 10), hex is base 16, making it more compact for representing large binary values. Each hex digit corresponds to four binary digits (bits), enabling easier translation between human-friendly numbers and machine language while maintaining efficiency.
