Although the definition of multimedia is a simple one, making it work can be complicated. The users need to know how to use multimedia computer tools and technologies to weave them together. Multimedia system is a system capable of processing multimedia data and applications (Coorough, 2001).
The software vehicle, the messages, and the content presented on a computer or television screen – together constitute a multimedia project (Vaughan, 2001). A multimedia project need not to be interactive to be called multimedia. People can sit back and watch multimedia just as they watch movie or television. The way users start watching multimedia at the beginning and running through an end is called “linear.” When users are given navigational control and can wander through the content at will, multimedia becomes “nonlinear” and “interactive,” and is a powerful gateway to information (Vaughan, 2001).
Hypertext Hypertext is a computer-based text retrieval system that enables a user to access particular locations in webpages or other electronic documents by clicking on links within specific webpages or documents. (answers.com, 2006).
Hypermedia Hypermedia is a term used as a logical extension of the term hypertext. Hypermedia is not constrained to be text-based. It can include other media, e.g., graphics, images, and especially the continuous media – sound and video, to create a generally non-linear medium of information. This contrasts with multimedia, which, although often capable of random access in terms of the physical medium, is essentially linear in nature.
The World Wide Web is a classic example of hypermedia, whereas a movie on a DVD is an example of standard multimedia. The lines between the two can (and often do) blur depending on how a particular technological medium is implemented (http://www.cs.
