An example of hypertext is the word "Facebook" that links to the Facebook page.
hypertext - Computer Definition
Text prepared and published in such a way that it is linked together in a non-sequential web of associations that allows the user to navigate through related topics, from one document to another.The author embeds hyperlinks in the text that the user can simply click on to view the related document associated with the link. The World Wide Web (WWW) is a global hypertext system of information residing on servers linked across the public Internet. If this dictionary were in electronic format with hypertext, you could simply click on just about any hyperlinked word (italicized in print) and instantly view the definition of that word, without having to flip pages to find it. Also, the last sentence in this paragraph would disappear, saving ink and paper in the process.The terms hypertext and hypermedia are attributed to Ted Nelson, who, along with Douglas Englebart, developed the Hypertext Editing System in 1968. See also HTML, hyperlink, Internet, server, text, and WWW.
A linkage between related information. Hypertext is the foundation of the World Wide Web, enabling users to click on a link to obtain more information on a subsequent page on the same site or from a website anywhere in the world. Hypertext is the umbrella term for all links, whether appearing as text (word, phrase or sentence) or as an icon or other graphical element, the latter technically called a "hypergraphic." The terms "hypertext," "hyperlink" and "link" are also used synonymously. See hypermedia, live link and virtual hypertext. The term was coined by Ted Nelson in 1963, but his vision was more expansive than the one-way links of today's Web. Nelson proposed two-way linking and support for non-hierarchical organization (for more information, visit www.xanadu.com). The World Wide Web = Hypertext The Web was developed in the early 1990s by Tim Berners-Lee and Robert Cailliau at the CERN European Laboratory for Particle Physics in Geneva, Switzerland. Whether the Web embodied hypertext as Nelson envisioned it or not, the linking of one item to another created the largest information explosion the world has ever witnessed.
