ASCII stands for the American Standard Code for Information Interchange. It was designed in the early 60's as a standard character-set for computers and hardware devices like teleprinters and tapedrives.

ASCII is a 7-bit character set containing 128 characters.

It contains the numbers from 0-9, the uppercase and lowercase English letters from A to Z, and some special characters.

The character-sets used in modern computers, HTML, and Internet are all based on ASCII.

ASCII device control characters

The first 32 characters in the ASCII-table are unprintable control codes and are used to control peripherals such as printers, and are listed for reference only.
