Hypertext
|
"A special type of database system, invented by Ted Nelson in the
1960s, in which objects (text, pictures, music, programs, and so on) can
be creatively linked to each other. When you select an object, you can
see all the other objects that are linked to it. You can move from one
object to another even though they might have very different forms" (Webopedia,
2002).

Hypermedia
|
"An extension to hypertext that supports linking graphics, sound,
and video elements in addition to text elements. The World Wide Web is
a partial hypermedia system since is supports graphical hyperlinks and
links to sound and video files" (Webopedia, 2002).

Node
|
A node is a unit of information in a hypertext system. Units of
information are sometimes called chunks. The closest comparison to
a node outside the hypertext world is a document. Nodes are linked together
to form a path (World Wide Web Consortium, 1995).
|
Path
|
An ordered set of nodes that provide a sequence in which nodes can
be read.
|
Links
|
Methods of connecting nodes of information together in a hypertext
environment. Links can be internal, referring to a source of information
or object within the document or external, pointing to an object or source
of information outside the document.
|
Anchor
|
The visible part of a link.
|
Menus
|
A collection of links that take you to various nodes of information.
Menus may be used in a structured hypertext environment. |
