ASCII
ASCII (American Standard Code for Information Interchange) is a character encoding standard using 7-bit to represent 128 characters used by computers and other devices for encoding letters, numbers, punctuation, and control codes into digital form. The first 33 ASCII code points are non-printing control codes including the carriage return, line feed, tab, and several obsolete non-printable codes stemming from its origin of representing telegraph codes. The other 95 are printable characters, including digits (0-9), lowercase (a-z) and uppercase (A-Z) letters, and punctuation symbols. In the modern age, most computer systems use Unicode instead, which is an extension of ASCII, supporting millions of code points. UTF-8 superseded ASCII on the Web in 2007.
