Every record on the Web is known as Web document or Web page. These reports pull together distinctive sorts of data, including content, graphics, sound, movement, and video. A related arrangement of Web pages is known as a Web Presentation, or website.

Web presentations are put stored on PCs, called Web servers, which are joined with the Internet. At the point when individuals get to the World Wide Web they utilize a product system called a Web program that empowers them to access, view, and explore every one of the archives on the Web.
