1.7.2 Multimedia and Entertainment
Multimedia is a combination of sound and images with text and graphics. This would include movies, animations, music, people talking, sound effects like the roar of a crowd and smashing glass.
Recording sounds for your computer requires special equipment. Microphones can capture sounds from the air, which is good for sound effects or voices.
Talking data into the computer when your hands and eyes are busy should certainly be more efficient. You can tell the computer what to do instead of typing commands, like saying "Save file". One has to be careful enough while giving the sound input with regard to pronounciation of words. Also there could be a problem that dictionary of understood words does not include some of the more "forceful" words.
A Digital Camera takes still photos but records the pictures on computer disks or memory chips. The information contained can be uploaded to a computer for viewing.
A Video Camera or Recorder (VCR) can record data that can be uploaded to the computer with the right hardware. Though it is not digital data, you can still get good results with the right software. Both of these take huge amounts of storage. Photos make for very large files.
A Web Cam is a tiny video camera designed especially to sit on your computer. It feeds pictures directly to the computer as their would be no tape or film to develop. Of course the length of the cable that connects the camera to the computer would be a limiting factor. But like any camera, it will take a picture of what you point it at.

Even basic office applications like a word processing package or a spreadsheet tool becomes a powerful tool with the aid of multimedia business. Pictures, animation and sound can be added to these applications, emphasizing important points in the documents.
Virtual reality is a truly absorbing multimedia application. It is an artificial environment created with computer hardware and software. It is presented to the user in such a way that it appears and feels real. In virtual reality, the computer controls three of the five senses. Virtual reality systems require extremely expensive hardware and software and are confined mostly to research laboratories.
Another multimedia application is Videoconferencing. Videoconferencing is conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data.
