HyperText Markup Language. A collection of tags used to mark blocks of text and assign them particular meanings. For instance, a word or phrase in a text can be associated with another document (hypertext link). HTML is used by the World Wide Web. A Web browser (e.g. Netscape) interprets HTML. A hypertext link may be revealed by underlining the word. A mouse click on the word will result in opening the associated document.
