in personal computing, software and applications that combine text, high-quality sound, two- and three-dimensional graphics, animation, photo images, and full-motion video. In order to work with multimedia, a personal computer typically requires a powerful microprocessor, large memory and storage capabilities, a high-quality monitor and a video accelerator, external loudspeakers or headphones and a sound card (or sound board) for improved sound generation, and a CD-ROM (see compact disc
) or DVD-ROM (see digital versatile disc
) drive, as well as special software to utilize many of these devices. A multimedia computer may also use other devices, such as a microphone or keyboard for audio input, a digital camera or scanner for graphics input, and a videocassette recorder or camcorder for video input or output. Multimedia software is used for electronic publishing and electronic games
and in employee-training programs. The term multimedia
is also used to describe home entertainment systems and other electronic products and services, particularly interactive ones, that combine text, sound, video, and the like. Uses include virtual reality
simulations, interactive television, commercial advertising, and hypertext
