What Link is
Text or images on a Web page that a user can click on in order to access or connect to another document. Links are most commonly thought of as the technology that connects two Web pages or Web sites. Once you click on a link, it could trigger a variety of events: It could "jump" to a different page or to another place on the same Web page; it could link to a file that will start downloading to your computer; it could trigger the launch of a helper application that will then process the clicked-on file, it could launch your e-mail program so you can send a message, and so on. What actually occurs when you click on a link is determined by the file's MIME type and the way your computer system is configured (or set up) to handle that MIME type. For example, browsers are configured to display all files that have HTML in their MIME extension. Links are also called hyperlinks, hypertext, and hot links, and they are coded in HTML by Web page authors or Web developers. The basic HTML code for using text to link to a Web site's homepage.
The meaning of Hypertext
A system for writing and displaying text that can be linked in multiple ways to related documents and available at several levels of detail. The term was coined by Ted Nelson to refer to a nonlinear system of information browsing and retrieval based on associative links between documents. The World Wide Web uses hypertext transfer protocol (HTTP) to link pages and multimedia files.
