It’s important to understand what binary is first.
A binary code is a way of expressing text or computer processor instructions by using the binary number system’s two-binary digits 0 and 1. This happens by assigning a bit string to each particular symbol or instruction. For example, a binary string of eight binary digits or bits can represent any of 256 possible values and can therefore correspond to a variety of different symbols, letters or instructions.
In computing and telecommunication, binary codes are used for any of a variety of methods of encoding data, such as character strings, into bit strings.
