ASCII
Acronym for American Standard Code for Information Interchange. The standard code used for information interchange among data processing systems, data communications systems, and associated equipment in the United States. Note 1: The ASCII character set contains 128 coded characters. Note 2: Each ASCII character is a 7-bit coded unique character; 8 bits when a parity check bit is included. Note 3: The ASCII character set consists of control characters and graphic characters. Note 4: When considered simply as a set of 128 unique bit patterns, or 256 with a parity bit, disassociated from the character equivalences in national implementations, the ASCII may be considered as an alphabet used in machine languages. Note 5: The ASCII is the U.S. version of International Reference Alphabet (IRA) No. 5 (formerly International Alphabet No. 5, or "IA5") as specified in ITU-T Recommendation T.50.
