Binary code

From Wikipedia, the free encyclopedia

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.

[edit] Early uses of Binary codes

Anton Glaser, in History of Binary and other Nondecimal Numeration. Tomash. 1971. ISBN 0-938228-005. , Chapter VII Applications to Computers, cites the following Pre-ENIAC milestones.

• 1932: C.E. Wynn-Williams "Scale of Two" counter
• 1938: Atanasoff-Berry Computer
• 1939: Stibitz: "excess three" code in the Complex Computer

[edit] Weight of binary codes

The weight of a binary code, as defined in [1], is the Hamming weight of the binary words coding for the represented words or sequences.
