This creates links to other text or visual materials that can be located on the same file or in other computers as it is the case of Web links. Hypertext documents can create associations among related concepts in a similar way as the cognitive psychologists claim we humans learn. A Web server is a computer that has the software needed for letting Web users to look for the information stored in it in the form of Web home pages. Web publishers must have an account in a Web server to be able to place their home pages for users to access. As soon as a Web server is connected to the Internet, it becomes a Web site.
Web sites are the physical locations in which Web servers are placed.
Web sites include educational, governmental, and commercial institutions. Web browsers are special software packages that users must have installed in their computers to be able to connect to the Web. Netscape and Mosaic are two popular examples of Web browsers. Web browsers interpret the codes contained in the source documents that Web publishers produce through the use of the Hyper-Text Markup Language. Users surf through the Web either by clicking at hypertext materials contained in a particular home page or by typing the electronic address of a specific home page in the URL format.
