An Hyperlink is an element in an electronic document that links to another place in the same document or to an entirely different document.
Typically, you click on the hyperlink to follow the link. Hyperlinks are the most essential ingredient of all hypertext systems, including the World Wide Web.
An Hypertext is a special type of database system, invented by Ted Nelson in the 1960s, in which objects (text, pictures, music, programs, and so on) can be creatively linked to each other.
When you select an object, you can see all the other objects that are linked to it. You can move from one object to another even though they might have very different forms.
For example, while reading a document about Mozart, you might click on the phrase Violin Concerto in A Major, which could display the written score or perhaps even invoke a recording of the concerto. Clicking on the name Mozart might cause various illustrations of Mozart to appear on the screen. The icons that you select to view associated objects are called Hypertext links or buttons.
Hypertext systems are particularly useful for organizing and browsing through large databases that consist of disparate types of information. There are several Hypertext systems available for Apple Macintosh computers and PCs that enable you to develop your own databases. Such systems are often called authoring systems . HyperCard software from Apple Computer is the most famous.
