ASCII (/ˈæskiː/ ^ⓘ ASS-kee),^[3]^: 6 an acronym for American Standard Code for Information Interchange, is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices. ASCII has just 128 code points, of which only 95 are printable characters, which severely limited its scope. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers, including Unicode which has over a million code points, but the first 128 of these are the same as ASCII.

The Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII for this character encoding.^[2]

ASCII is one of the IEEE milestones.^[4]
