'''ASCII''' is a common historical [[character encoding]], designed to represent US English text in digital form. The acronym stands for American Standard Code for Information Interchange.  Most of the character encodings in common current use are [[proper superset]]s of ASCII: these include the [[ISO 8859]] family of encodings, the [[Windows 1252]] code page and the [[UTF-8]] encoding of the [[Unicode]] character set.

Each character is assigned a number from 0 to 127, encoded in [[binary]].  In addition to the 26 letters of the [[English alphabet]] in upper and lower case, many common punctuation symbols are assigned codes, as are [[control characters]], such as backspace, carriage return and linefeed.

Because there are 128 separate codes, an ASCII character can be represented by a [[signed char]] type in the [[C]] programming language.
