'''Binary code''' is the system of representing [[text]] or [[Instruction (computer science)|computer processor instructions]] by the use of the [[binary number system]]'s two-[[binary digit]]s "0" and "1". A [[String (computing)|binary string]] of eight digits ([[bit]]s), 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 string]]s, into [[bit string]]s. Those methods may be fixed-width or [[variable-length code|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 encoding]]s for them.
A bit string, interpreted as a binary number, can be [[Binary numeral system#Decimal| translated into a decimal number]].
==Early uses of Binary codes==
Anton Glaser, in {{cite book |title=History of Binary and other Nondecimal Numeration |publisher=Tomash|date =1971|isbn = 0-938228-005 }}, Chapter VII ''Applications to Computers'', cites the following Pre-ENIAC milestones.
* 1932: [[Charles Wynn-Williams|C.E. Wynn-Williams]] "Scale of Two" counter
* 1938: [[Atanasoff-Berry Computer]]
* 1939: Stibitz: "excess three" code in the [[George Stibitz#Computer|Complex Computer]]
==Weight of binary codes==
The weight of a binary code, as defined in [http://www.research.att.com/~njas/codes/Andw/], is the [[Hamming weight]] of the binary words coding for the represented words or sequences.
