How is the World Wide Web linked?
The Web functions as a distributed hypermedia system. The purpose of this system is to allow the exchange of information across the Internet in the form of hypertext documents called Web pages or home pages. Hypertext is text with pointers or links to further information in various formats (text, graphic, video), allowing you to branch off to another document for more information on a given topic, and then return to the same location in the original document with ease. Pointers in a Web document are analogous to HyperCard stacks or Microsoft help files in which you click on an option (a pointer or a link) and the program moves you to another document, or location. Documents published on the Web are constructed in hypertext markup language, or HTML. This is a simple language that allows you to format text, insert images and sound, and create links in a document. Tutorials on creating Web services are available at the NCSA Mosaic Home Page, the automatic starting place for Web exploratio
