Hypertext and Hypermedia
Hypertext is a term you'll frequently hear associated with the Web. A hypertext document is a document that contains links to other documents, allowing you to jump between them by clicking the links. It's also a term associated with help files and other types of documents that are linked together. For example, if you've published a report that cites several sources, you can link the references of those sources to related works.
Likewise, if you're discussing the migratory habits of the nerd-bird, you can provide links to Web pages where nerd-birds are known to frequent.
Hypermedia is based upon hypertext but contains more than text. It contains multimedia such as pictures, videos, and audio. In hypermedia documents, pictures are frequently used as links to other documents. You can link a picture of Edinburgh to a Web site in Edinburgh, for example. There are countless types of multimedia you can include on a Web page, and some of those can serve as links to other Internet documents and resources
