ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable and 33 control characters a total of 128 code points. 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; for example, the first 128 code points of Unicode are the same as ASCII.

The NATO phonetic alphabet, officially the International Radiotelephony Spelling Alphabet, is an internationally recognized set of names for the letters of the Latin alphabet and the Hindu-Arabic digits. It is most commonly used in radio communication, where the usual names of the letters are likely to be misheard. It was defined in 1955–1956 by the International Civil Aviation Organization (ICAO).
