In mathematics, a “base” or a “radix” is the number of different digits or combination of digits and letters that a system of counting uses to represent numbers.

Base 2 (Binary) — Represent any number using 2 digits [0–1]

Base 8 (Octal) — Represent any number using 8 digits [0–7]

Base 16(Hexadecimal) — Represent any number using 10 digits and 6 characters [0–9, A, B, C, D, E, F]
