American Standard Code for Information Interchange is a character-encoding scheme based on the ordering of the English alphabet. ASCII codes represent text in computers and devices that use text. It includes definitions for 128 characters - 94 printable and 33 non-printable.

ASCII (American Standard Code for Information Interchange) is a character encoding of eight bits based on the English alphabet. ASCII codes represent text in computers, communications equipment, among other devices that work with text. Developed since 1960, most of the modern character encodings have inherited as a base.

The code defines 256 characters, completely filling the eight bits available. Of these, 33 are not printable, such as control characters not currently usable for text editing, but widely used in communication devices, which affect the processing of the text. Except for the space character, the rest is composed of printable characters.
