The WWW is a new medium that has flourished rapidly over the past year. Traffic on the WWW has been doubling every two to three months in this period. The WWW brings together three major principles: hypertext, logical markup and global networking. This means that all forms of previously printed (and electronically recorded) media can be stored in a logical and device independent electronic form which can be accessed and distributed all over the Internet.
In order to access and view this information special programs, called browsers, are required. Mosaic [8] browsers are among the most popular. They were developed at the U.S. National Centre for Supercomputing Applications, and are available for Unix, Macintosh and IBM machines.
Hypertext is the core principle upon which the WWW is based allowing links to documents, images or any anchor within such documents to be made. The breaking up of a document into logical elements (titles, headers, paragraphs, highlighting etc.) also enables documents to be viewed with a high degree of device portability [9]. This process is called marking up. The hypertext markup language, HTML [7][2], was developed as a non-proprietary delivery format for global hypertext and as such Mosaic and other browsers view HTML documents.
All our courseware is ultimately written in HTML and use Mosaic.
