Revolution of Multimedia 

Multimedia, in computer science, the presentation of information using the combination of text, sound, pictures, animation and video. Common multimedia computer applications include games, learning software and reference materials, such as an encyclopedia. Most multimedia applications include pre-defined associations, known as hyperlinks that enable users to switch between media elements and topics. Thoughtfully presented multimedia can enhance the scope of presentation in ways that are similar to the roving associations made by the human mind. Connectivity provided by hyperlinks transforms multimedia from static presentations with pictures and sound into an endlessly varying and informative interactive experience. Multimedia applications are computer programmes, typically they are stored on compact discs (CD-ROMs). They may also reside on the World Wide Web, which is the media-rich component of the international communication network known as the Internet. Multimedia documents found on the World Wide Web are called web pages. Linking information together with hyperlinks is accomplished by special computer programme or computer languages. The computer language used to create web pages is called Hypertext Markup Language (HTML).

Multimedia applications usually require more computer memory and processing power than the same information represented by text alone. For instance, a computer running multimedia applications must have a fast central processing unit (CPU), which is the electronic circuitry that provides the computational ability and control of the computer. A multimedia computer also requires extra electronic memory to help the CPU  in making calculations and to enable the video screen to draw complex images. The computer also needs a high capacity hard disk to store and retrieve multimedia information and a compact disc drive to play CD-ROM applications. Finally, a multimedia computer must have a keyboard and a pointing device, such as a mouse or a trackball, so that the user can direct the associations between multimedia elements. The larger, sharper and more colourful an image is, the harder it is to present and manipulate on a computer screen. Photographs, drawings and other still images must be changed into a format that the computer can manipulate and display. Such formats include bit-mapped graphics and vector graphics. Animation can also be included in multimedia applications to add motion to images. Animations are particularly useful to simulate real-world situations, such as the flight of a jet airplane. Animation can also enhance existing graphics and video elements adding special effects such as morphing, the blending of one image seamlessly into another.

Multimedia elements included in a presentation require a framework that encourages the user to learn and interact with the information. Interactive elements include pop-up menus, small windows that appear on the computer screen with a list of commands or multimedia elements for the user to choose. Scroll bars, usually located on the side of the computer screen, enable the user to move to another portion of a large document or picture.

The integration of the elements of a multimedia presentation is enhanced by hyperlinks. Hyperlinks creatively connect the different elements of a multimedia presentation using coloured or underlined text or a small picture, called an icon, on which the user points the cursor and clicks on a mouse.

Multimedia has had an enormous impact on education. For example, medical schools use multimedia-simulated operations that enable prospective surgeons to perform operations on a computer-generated virtual patient. Similarly, students in engineering schools use interactive multimedia presentations of circuit design to learn the basics of electronics and to immediately implement, test and manipulate the circuits they design on the computer. Even in elementary schools, students use simple yet powerful multimedia authoring tools to create multimedia presentations that enhance reports and essays. Multimedia is also used in commercial applications. For instance, some amusement arcades offer multimedia games that allow players to race Indy cars or battle each other from the cockpits of make-believe giant robots. Architects use multimedia presentations to give clients tours of houses that have yet to be built. Mail-order business provide multimedia catalogues that allow prospective buyers to browse virtual showrooms.
