ASCII stands for 'American Standard Code for Information Interchange'. ASCII is a character-encoding scheme based on the ordering of the English alphabet. Since ASCII only contains definitions for 128 characters, numerous other encoding schemes have been created to include characters from other alphabets and other symbols.
