The term "DVD" is not an acronym, although it is popularly understood to stand for digital video disc or digital versitle disc. This product grew out of laser disc, or compact disc (CD), technology and offers high-density optical and audio storage for both entertainment and computing purposes. The storage capacity of DVD is greater than that of the CD, and is available with a double-layer design for twice the capacity. Like the laser disc, DVD offers video, audio and data storage capabilities. DVD offers enhancements that a conventional CD does not, however. The audio DVD offers Dolby digital surround-sound. In the realm of video, DVD offers higher-quality video, the ability to contain longer films and the ability to move to a specific scene instantaneously. For computing, the DVD-ROM can store 20 times the information of a CD-ROM and offers enhanced graphics and faster movement.
