Guy Harris (talk | contribs) Undid revision 1248664528 by Jeffcho565 (talk) - 1) what's so special about 32 bits? Binary has been used in non-32-bit systems, and even non-power-of-2-word-size systems, in the past and most current general-purpose systems are 64-bit. 2) Wikipedia is *NOT* a valid source for claims in Wikipedia articles. |

Line 6:
In computing and telecommunications, binary codes are used for various methods of [[encoding]] data, such as [[character string]]s, into bit strings. Those methods may use fixed-width or [[variable-length code|variable-width]] strings. 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 number#Decimal|translated into a decimal number]]. For example, the [[letter case|lower case]] ''a'', if represented by the bit string <code>01100001</code> (as it is in the standard [[ASCII]] code), can also be represented as the decimal number "97"
