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.
