ASCII (American standard code for information interchange)

Pronounced ASK-ee, this venerable standard describes a set of 128 characters used to display text. When early computer development was taking place in the United States, this was sufficient for all textual needs. However, larger character sets, such as Unicode (which contain letters, symbols, and ideographs for virtually all of the world's languages) are now more common. Still, ASCII will be around for a long time. UTF-8 is a new character set based on ASCII that includes methods for referencing any Unicode character. See also character encoding, character set.
