A CDE Definition
(Hypertext REFerence) The HTML code used to create a link to another page. The HREF is an attribute of the anchor tag, which is also used to identify sections within a document. The HREF contains two components: the URL, which is the actual link, and the clickable text that appears on the page, called the "anchor text."
Relative (implicit) and Absolute (explicit) Links
In the first part of the following example, the URL comprises only the file name EXAMPLES.HTML, which is the Web page (Web document) to link to. Because only the file name is given, it is implied that EXAMPLES.HTML resides in the same folder as the Web page with the link. Relative links are widely used because there are no changes required if the pages are moved to a different folder or if the folder is renamed. Every link points within.
However, if EXAMPLES.HTML were on a different website, the full URL with an HTTP:// prefix has to be used, as in the second example. In both cases, the words SAMPLE PRODUCTS are the anchor text, which the user sees and clicks. See hypertext.
A linkage between related information. Hypertext is the foundation of the World Wide Web, enabling users to click or tap a link in order to switch to another part of the same Web page, another page on the same site or to 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 all 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.
