WEB TERMINOLOGIES
• Page or web page: a file that can be read over the world wide web • Pages or web pages: the global collection of documents associated with and accessible via the world wide web • Hyperlink: a string of clickable text or a clickable graphic that points to another web page or document. When the hyperlink is selected, another web page is requested, retrieved and rendered by the browser.
• Hypertext: web pages that have hyperlinks to other pages. More generally, any text having nonlinear links to other text • Browser: a software tool used to view web pages, read email, and read newsgroups, among other things. Browsers are also called web clients • Multimedia: information in the form of graphics, audio, video, or movies. A multimedia document contains a media element other than just plaintext.
• Hypermedia: media with links and navigational tools • Uniform resource locator: a string of characters that specify the address of a web page • Surfer: a person who spends time exploring the world wide web • Web presentation: a collection of associated and hyperlinked web pages. Usually, there is an underlying theme to the pages. For example, a web presentation for a company may describe facts about the company, its employees, its products, and the method of ordering the products on-line.
• Webmaster: a person who maintains, creates, and manages a web presentation, often for a business, organization, or university. This person usually “signs” web pages, so that questions and comments can be sent to them. • Web manager: synonym for webmaster • Web site: an entity on the internet that publishes web pages. A web site typically has a computer serving web pages, whereas a web presentation is the actual web pages themselves.
• For example, www. cug. edu. gh is the name of a web site, whereas www. cug. edu. gh/homepage. html is the name of a web presentation • Web server: a computer that satisfies user requests for web pages. • Mirror site: a site that contains a duplicate copy of a web presentation from another site. If a web presentation is extremely popular, other sites may be used to mirror the original presentation; that is they contain the same information as the original site.
• This allows the load on the web server and the network to be distributed. If one server is down, a mirror site can be tried. If several mirror sites exist, it is a good idea to try the one closest to you first
