ASCII

ASCII (pronounced: /ˈæskiː/), an acronym for American Standard Code for Information Interchange, is a character encoding standard used in computers and electronic devices to represent text. It was developed by the American National Standards Institute (ANSI) in the 1960s.

Etymology

The term ASCII is derived from the English phrase "American Standard Code for Information Interchange". It was designed to facilitate the interchange of information among various types of data processing equipment.

Description

ASCII is a 7-bit character set containing 128 characters. It contains the numbers from 0-9, the upper and lower case English letters from A to Z, and some special characters. The ASCII standard allows ASCII-only text files to be freely interchanged and readable on Unix, Macintosh, Microsoft Windows, DOS, and other systems.

ASCII Table

The ASCII table includes control characters, printable characters and the extended ASCII characters. Control characters are non-printing and control the interpretation or display of text. Printable characters represent letters, digits, punctuation marks, and a few miscellaneous symbols. Extended ASCII includes 128 additional characters.
