+'''ASCII''' (an acronym for '''American Standard Code for Information Interchange''') is an encoding for various glyphs (written forms such as letters, numbers, etc) into 7-[[bit]] numeric form. It was created by a predecessor to [[American National Standards Institute|ANSI]].
 Originally based on the English alphabet, the supported set for ASCII includes not only numbers, letters (upper- and lower-case) but also punctuation, and other special-purpose characters (from then-common ones like '@', '#', etc, to others that ASCII has made popular - '^', '|', etc). It also includes non-printing characters used for control of printing [[terminal]]s - tab, line feed, carriage return, etc.
-ASCII was developed in the early 1960s from telegraph code. Its first commercial use, in 1963, was as a teleprinter code promoted by Bell data services for the TWX network. Later, it was adopted for use by terminals, [[line-printer]]s, etc, as well as by [[secondary storage]] and [[file]]s.

 ASCII soon superseded an earlier wide-spread encoding, [[SIXBIT]], which allowed 6 characters to be carried in the then-common 36-bit [[word]]s common on many computers (but only supported upper-case characters).

-ASCII was eventually used by [[personal computer]]s such as the [[Apple II]], and the [[IBM PC]]. IBM extended the character set with a separate set of glyphs used for line drawing; the first of many often-incompatible extensions to ASCII for various national, etc, usages. It has now been superseded for the [[World Wide Web|WWW]] by [[UTF-8]], which is however backwards compatible with ASCII.

-ASCII was developed from telegraph code. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. ... Originally based on the English alphabet, ASCII encodes 128 specified characters into seven-bit integers, Later, it was adopted for use in tele-printers, terminals and personal computers such as the Apple II, and the IBM PC. IBM extended the character set with a separate set of glyphs used for line drawing.
+Originally based on the English alphabet, the supported set for ASCII includes not only numbers, letters (upper- and lower-case) but also punctuation, and other special-purpose characters (from then-common ones like '@', '#', etc, to others that ASCII has made popular - '^', '|', etc).
