ASCII (Listeni/ˈæski/ ass-kee), abbreviated from American Standard Code for Information Interchange, is a character-encoding scheme.
Originally based on the English alphabet, it encodes 128 specified characters into 7-bit binary integers.
The characters encoded are numbers 0 to 9, lowercase letters a to z, uppercase letters A to Z, basic punctuation symbols, control codes that originated with Teletype machines, and a space.
For example, lowercase j would become binary 1101010 and decimal 106.
ASCII codes represent text in computers, communications equipment, and other devices that use text.
Most modern character-encoding schemes are based on ASCII, though they support many additional characters.
