- 33. Hypermedia ▫ Hypermedia isa way of organizing multimedia information by linking media elements. ▫ Hypermedia has grown out of a fusion between hypertext and multimedia. ▫ Hypertext was developed to provide a different structure for basic text in computer systems : text is essentially sequential in nature, even though its structure is hierarchical (chapters, sections, subsections, paragraphs) hypertext was developed to permit more random access between components of text documents, or between documents, to allow a greater degree of flexibility and crossreferencing than a purely linear or sequential model would allow.
- 34. Hypermedia – – The structure ofa hypermedia organizations is called a hypermedia web, which consists of a number of multimedia elements or nodes with links between them. Links represent semantic relationships, thus when a link exists between two nodes they must be related in some fashion : a digital image linked to a textual description of it a slide-show linked to an audio commentary – Most widely used hypermedia tools are hypermedia browsers, which let users view nodes and traverse links between them, and markup languages, such as HTML, which allow users to create hypermedia webs as structured documents.
