American National Standards Institute

From Academic Kids

The American National Standards Institute (ANSI) is a private, non-profit standards organization that produces industrial standards in the United States. It is a member of ISO and IEC.

ANSI's standards fall in many areas. In computing, ANSI standardized the ASCII character set in X3.4, control codes in X3.41 and control sequences (to be used e.g. for moving the cursor around the screen of a "dumb" terminal) in X3.64.

The ASA photographic exposure system became the basis for the ISO film speed system, currently used worldwide.

ANSI was founded on October 19, 1918 as the American Engineering Standards Committee and reorganised as the American Standards Association in 1928. In 1966 it was reorganised as the United States of America Standards Institute. In 1969 it changed its name to American National Standards Institute.

In Microsoft Windows, the phrase "ANSI" refers to the Windows ANSI code pages. Most of these are fixed width though there are some variable width ones for ideographic languages. Some of these are very close to the ISO-8859 series leading many to falsely assume that they are identical.

ASCII art which is colorized or animated by way of ANSI terminal control codes (X3.64 sequences) are commonly referred to as "ANSI art" and were predominantly popular on bulletin board systems throughout the 1980s and 1990s.
