The most popular systems are:

- The binary numeral system (base-2) represents numeric values using two symbols: 0 and 1. It is of great importance in digital electronics.
- The decimal numeral system (base-10) has ten as its base and thus uses the digits from 0 to 9. It is the numerical base most widely used by modern civilizations.
- The hexadecimal system (base 16) uses the symbols 0-9 and A-F to represent numbers. The primary use of hexadecimal notation is a human-friendly representation of binary-coded values. Each hexadecimal symbol conforms to four bits. E.g. 11110011 in base-2 gives F3 in base-16.
