Which numbering system is represented as base 16?

The numbering system represented as base 16 is known as hexadecimal. This system uses sixteen distinct symbols to represent values: the numbers 0-9 and the letters A-F, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15. Each digit in a hexadecimal number represents a power of 16, which is particularly useful in various computing applications because it allows for a more compact representation of binary values.

For instance, a single hexadecimal digit can represent four binary digits (bits), making it easier to read and interpret large binary numbers. This efficiency is one reason why hexadecimal is commonly used in programming and digital electronics, particularly in defining colors in web design and setting memory addresses in computer systems.
