ASCII

ASCII is a variant of international alphabet No. 5 of the CCITT (International Telegraph and Telephone Consultative Committee) (or 7-bit ISO code) used for information exchange. This is the code for representing a set of characters composed of the 26 lower case and upper case letters, the digits 0 to 9, the punctuation signs, special characters and command characters.
There is an 8-bit ASCII code initially devised for microcomputers, which includes accented lower case letters.
