HYPERLINK

HYPERLINK

Hyperlink is a reference to data that the reader can directly follow either by clicking or by hovering or that is followed automatically.^[1] A hyperlink points to a whole document or to a specific element within a document.Hypertext is text with hyperlinks. A software system for viewing and creatinghypertext is a hypertext system, and to create a hyperlink is to hyperlink (or simply to link). A user following hyperlinks is said to navigate or browse the hypertext.

TWO TYPES OF HYPERLINK:

• HYPERTEXT
• HYPERMEDIA

HYPERTEXT

Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text which the reader can immediately access, or where text can be revealed progressively at multiple levels of detail (also calledStretchText). The hypertext pages are interconnected by hyperlinks, typically activated by a mouse click, keypress sequence or by touching the screen. Apart from text, hypertext is sometimes used to describe tables, images and other presentational content forms with hyperlinks. Hypertext is the underlying concept defining the structure of the World Wide Web,^[1] with pages often written in theHypertext Markup Language (aka HTML). It enables an easy-to-use and flexible connection and sharing of information over the Internet.

Note how hypertext is not just flat text with highlights or paragraphs omitted during display, but rather, the text is hyper-structured with hyperlinks or other structures embedded inside a page, including hidden search words, to control the display and connection with other pages or hypertext node.

HYPERMEDIA

Hypermedia, an extension of the term hypertext, is a nonlinear medium of information which includes graphics, audio, video, plain text and hyperlinks. This contrasts with the broader term multimedia, which may include non-interactive linear presentations as well as hypermedia. It is also related to the field of electronic literature. The term was first used in a 1965 article by Ted Nelson.^[1]

The World Wide Web is a classic example of hypermedia, whereas a non-interactive cinema presentation is an example of standard multimedia due to the absence of hyperlinks.

The first hypermedia work was, arguably, the Aspen Movie Map. Bill Atkinson's HyperCard popularized hypermedia writing, while a variety of literary hypertext and hypertext works, fiction and nonfiction, demonstrated the promise of links. Most modern hypermedia is delivered via electronic pages from a variety of systems including media players, web browsers, and stand-alone applications (i. e., software that does not require network access). Audio hypermedia is emerging with voice command devices and voice browsing.
