Topic 13: Binary Code

Binary code is the system of representing text or computer processor instructions by the use of the binary number system's two-binary digits "0" and "1". A binary string of eight digits (bits), for example, can represent any of 256 possible values and can correspond to a variety of different symbols, letters or instructions. In 8-bit ASCII code the lowercase a is represented by the bit string 01100001.

In computing and telecommunication, binary code is 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.
