Base-16 (hexadecimal)

Base-16, or hexadecimal, is a numbering system that uses 16 symbols to represent values: 0-9 and A-F, where A-F correspond to decimal values 10-15. Unlike our familiar decimal system (base-10), hexadecimal simplifies the representation of large binary numbers used in computers. Each hexadecimal digit corresponds to four binary digits (bits). For example, the decimal number 15 is represented as 'F' in hexadecimal, and the number 255 is 'FF'. Hexadecimal is widely used in computing for concise representation of binary data, making it easier for humans to read and work with digital information.
