HTML (HyperText Markup Language)

Short for HyperText Markup Language, the authoring language used to create documents on the World Wide Web. HTML is similar to SGML (Standard Generalized Markup Language), although it is not a strict subset. HTML defines the structure and layout of a web document by using a variety of tags and attributes. The correct structure for an HTML document starts with <HTML><HEAD> (enter here what document is about), <BODY> and ends with </BODY></HTML>. All the information you'd like to include in your web page fits in between the <BODY> and </BODY> tags.

There are hundreds of other tags used to format and layout the information in a web page. Tags are also used to specify hypertext links. These allow web developers to direct users to other web pages with only a click of the mouse on either an image or word(s).
