Definition: ASCII is short for American Standard Code for Information Interchange, and is a 7 bit encoding of characters on computers. There are 128 values ranging from 0 to 127, of which 95 are printable characters and 33 are not visible but used for control characters. Carriage return (0xD16 in hexadecimal) and linefeed (0xA16 ) are two of the better known control characters.
Although ASCII has been superseded somewhat by the 16 bit Unicode, it lives on as the first 128 characters in the Unicode set.
