 World Wide Web

The World Wide Web consists of files, called pages or web pages, containing links to documents and resources throughout the internet.

The World Wide Web (abbreviated Web or WWW) was developed in 1989 by Tim Berners Lee in Switzerland. The initial purpose of the Web was to use Networked hypertext to facilitate communication among its members. A rapid growth in the number of both developers and users led to incorporation of graphics, videos and sounds.

Hypertext

Hypertext is a document containing words that connect to other documents. These words are called links and are selectable by the user. A single hypertext documents, images, videos and sound. The entire operation of Web mainly relies on hypertext.

It provides a more flexible way to design web pages, along with text With HTML, tags are replaced within the text for document formatting, like font size, italics and bold, and the creation of hypertext links. Graphics and multimedia can also be included in an HTML document.

Web Browsers use the Uniform Resource Locator to retrieve the file from the host computer and the specific directory in which it resides.

ISP

The Windows Media Player, RealPlayer and QuickTime plug-ins play streaming audio and video files. Extensive files such as interviews, speeches, hearings and televised video clips work very well with these players. They are also ideal for the broadcast of real-time events.

Shockwave and Flash are plug-ins that offers the creation and implementation of an entire multimedia displays combining graphics, animations and sounds.
