HTML - (Hypertext Markup Language)

HTML is the basic language that is used in creating hypertext documents on the World Wide Web. It is used in basic, plain ASCII-text documents, but when those documents are interpreted (called rendering) by a web browser, the document can display formatted text, color, a variety of fonts, graphic images, sound, video clips, run programs, perform special effects and handle hypertext jumps to other Internet locations anywhere in the world.

If HTML has never been used before to create a page, there are excellent tutorials available at: www.webmonkey.com
