| Hypertext is a protocol for linking parts of documents to other documents or to parts
of other documents. Clicking on a "hot spot" in a hypertext document activates a
hypertext link in the underlying software, taking the reader to the linked item. These
items may be text, audio, graphics, or video documents—separate files coded in
hypertext markup language (HTML). HTML files are read by a Web browser, a mouse-driven
software interface like the one you are using to consult this Web database. Writing
text-based course materials in HTML is no more complex than using a wordprocessor, and the
hyperlinking function allows a course developer to build interactivity into the
courseware, presenting students with options and paths to follow depending on their
interests, for example, or on the answers they give to self-test questions. Resources
