Description
A binary code is a way of representing text or computer processor instructions by the use of the binary number system's two-binary digits 0 and 1. This is accomplished by assigning a bit string to each particular symbol or instruction. For example, a binary string of eight binary digits (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. Those methods may be fixed-width or variable-width. In a fixed-width binary code, each letter, digit, or other character, is represented by a bit string of the same length; that bit string, interpreted as a binary number, is usually displayed in code tables in octal, decimal or hexadecimal notation. There are many character sets and many character encodings for them.
A bit string, interpreted as a binary number, can be translated into a decimal number. For example, the lowercase "a" as represented by the bit string 01100001, can also be represented as the decimal number 97.[1]
