Binary

Binary addition follows the same rules as normal addition, but only uses the digits 0 and 1.

Binary is a number system that uses only 0s and 1s. It is the language of computers because electronic circuits naturally represent two states: off and on.

A bit is the smallest unit of data in computing, and 8 bits make one byte.

Hexadecimal is a base-16 number system that computer scientists use as a shorthand for binary.
