At last it can be concluded that multimedia is a computer based system of communication that includes text, audio, video, animation, graphics, interactive computing etc. Multimedia tends to imply sophistication (and relatively more expense) in both production and presentation than simple text-and-images. Multimedia presentations are possible in many contexts, including the Web, CD-ROMs, and live theater. In this system, this media can be used independently or jointly in expressing any human feeling or any message.
