What is a number base?

A number's base defines how many and which digits are available to express a certain number. The most common base for us humans is base 10, also called Decimal, which offers ten digits (0-9) for us to write our numbers.

Computers however, often use the Binary base, or base 2, meaning that they only use two digits (0 and 1) to express their numbers.

Another common base is called Hexadecimal (base 16), which allows for sixteen digits. This base, along with the other bases between 11 and 25 included, work by adding letters to the list of available digits. For base 16, those would be 0-9, and then A-F following the alphabet.

Base 26 is another base that can be used for encryption, as it uses the 26 letters of the alphabet. This base uses no numbers, and can be used to turn words into a number.
