Hyper Text and Hypermedia

Hypertext is a term that will be frequently heard in association 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're discussing tthe habits of the bird, you can provide links to Web pages where 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.

A link really has two different parts. First, the part you see on the Web page called an anchor. Second, is the URL reference that tells the browser what do do if that link is clicked. When the user clicks a link's anchor the browser loads the file or document given by the link's corresponding URL reference.

A link's anchor can be a word, a group of words, or a picture. The appearance of the anchor depends on what type of anchor it is and how the user has configured the browser to display links. There are only two types of anchors: text and graphical.

The other part of a link is the URL reference. This is the address of the Webpage the browser loads if you click the link. Every type of link, whether it uses a text or graphical anchor, uses either a relative or absolute reference.

An URL reference to a file on the same computer is also known as a relative reference. That means that the URL is relative to the computer and directory from which the browser originally loaded the Web page. The relative reference is also called as partial URL. An URL reference that specifies the exact computer, directory, and file for a Web page is an absolute reference. The absolute reference is also known as complete URL.
