Hypertext is a way to link words or phrases in documents to other documents. Hypertext makes it easy to explore material related to a certain topic. The method of accessing information on the Web is quite different from reading a book.

Web documents can contain text, images, video clips, and audio clips.

It is this standard that allows the user to view Web documents from any computer running Web software. The open standard of HTML allows many users with different computer systems to share the same information.
