ASCII stands for American Standard Code for Information Interchange, a computer abbreviation.

Character encoding that assigns the numbers 0 to 127 to English letters, digits, punctuation and control codes, so that A is 65 and a space is 32. It became the foundation of nearly every later text encoding, including UTF-8.

Example: Save the file as plain ASCII text so the old terminal can display it.

Usage notes

First published in 1963 by the American Standards Association, ASCII uses 7 bits. The many 8-bit "extended ASCII" code pages that added accented letters were mutually incompatible, one reason Unicode was created. Pronounced "ASK-ee". Control codes 10 (line feed) and 13 (carriage return) still define line endings, and ASCII art draws pictures with its characters.
