ASCII (American Standard Code for Information Interchange, American Information Interchange standard codes) is a computer coding system based on the Latin alphabet. It is mainly used to display modern English and other Western European languages. It is the most common single byte coding system today, and is equivalent to international standard ISO/IEC 646.
