ASCII was the first character set (encoding standard) used between computers on the Internet.
Both ISO-8859-1 (default in HTML 4.01) and UTF-8 (default in HTML5), are built on ASCII.
ASCII stands for the "American Standard Code for Information Interchange".
It was designed in the early 60's, as a standard character set for computers and electronic devices.
ASCII is a 7-bit character set containing 128 characters.
It contains the numbers from 0-9, the upper and lower case English letters from A to Z, and some
special characters.
The character sets used in modern computers, in HTML, and on the Internet, are all based on
ASCII.
American Standard Code for Information Interchange, is a character encoding standard for
electronic communication. ASCII codes represent text in computers, telecommunications
equipment, and other devices. Most modern character-encoding schemes are based on ASCII,
although they support many additional characters.
The use of ASCII format for Network Interchange was described in 1969.[9] That document was
formally elevated to an Internet Standard in 2015.[10]
