Hypermedia & Hypertext

Hypertext

*Hypertext is basically the same as regular text - it can be stored, read, searched, or edited.

*hypertext is text with pointers to other text.

*The browsers let you deal with the pointers in a transparent way -- select the pointer, and you are presented with the text that is pointed to.
Hypermedia.

Hypertext, made famous by the World Wide Web, is most simply a way of constructing documents that reference other documents. Within a hypertext document, a block of text can be tagged as a hypertext link pointing to another document.When viewed with a hypertext browser, the link can be activated to view the other document.Hypertext documents can either be static (prepared and stored in advance) or dynamic (continually changing in response to user input). Static hypertext can be used to cross-reference collections of data in documents, software applications, or books on CDs.

A good characteristics of good hypertext consists of:

-lots of documents
-lots of links
-range of details
-correct links

Hypermedia

*Hypermedia is a superset of hypertext.

*Hypermedia documents contain links not only to other pieces of text, but also to other forms of media - sounds, images, and movies.

*Images themselves can be selected to link to sounds or documents.

*This means that browsers might not display a text file, but might display images or sound or animations.

*Hypermedia simply combines hypertext and multimedia
