In computing, hypertext is a user interface paradigm for displaying documents which, according to an early definition (Nelson 1970), "branch or perform on request." Hypertext is a way of organising material that attempts to overcome the inherent limitations of traditional text and in particular its linearity. The prefix hyper- (Modern Greek term for over or beyond) signifies the overcoming of such constraints. The most frequently discussed form of hypertext document contains automated cross-references to other documents called hyperlinks. Selecting a hyperlink causes the computer to load and display the linked document. A document can be static (prepared and stored in advance) or dynamically generated (in response to user input). Therefore, a well-constructed hypertext system can encompass, incorporate or supersede many other user interface paradigms like menus and command lines, and can be used to access both static collections of cross-referenced documents and interactive applications. The documents and applications can be local or can come from anywhere with the assistance of a computer network like the Internet. The most famous implementation of hypertext is the World Wide Web. The term "hypertext" is often used where the term hypermedia would be more appropriate.
