Hyperlink

See also: Bond

A hyperlink or hypertext link or simply bond , is a reference in a system Hypertexte making it possible automatically to pass from a document consulted to a dependant document.

Source and destination

A hyperlink has a source (or origin) and a destination (or target). The activation of the element source of a hyperlink makes it possible to pass automatically to its destination.

The source of a hyperlink is generally an element (words, sentences, images) of a document hypertext. The destination can be another element of the same document, it acts then of an internal hyperlink to the document. The destination can also be another document, even a precise element of another document. Certain systems hypertexts do not guarantee that the destination exists: in this case one is likely to follow hyperlinks known as broken, broken or died.

A hyperlink is bidirectional if its destination is also the reciprocal source of the same bond. If not a bond is one-way and nothing distinguishes an element destination from any another element. The destination of a hyperlink is not inevitably a document hypertext. If necessary, the bond will be inevitably one-way.

World Wide Web

The hyperlinks of the World Wide Web are in the Web pages, more precisely in documents written in HTML ( Hypertext Markup Language ). The Web pages use the notation of URI ( Uniform Resource To identify ) to identify the referred documents.

The hyperlinks of the Web are one-way. This has two advantages for the Web. Firstly that makes it possible to use documents not hypertexts (in particular sounds, images, documents to be printed) like destination. Secondly that makes it possible to establish hyperlinks towards all the resources accessible from Internet, without coordination with the person in charge of the document of destination. The defect of this noncoordination is that the changes of the document of destination are likely to make the bond obsolete without the person in charge of the source nor of the destination of realizing there. The most visible problem appears when the document of destination is removed: the bond “is then broken”, it refers to a disappeared document (Erreur 404).

The technique at the base of the hyperlinks of the Web is also used to include images or under-pages in the Web pages. A terminology developed to differentiate these various applications from the technology of the Web: | It is the Hotlinking, juridically delicate |}
