What is dvd and dvd-rom, Computer Engineering

DVD is a new technology very same to compact discs. A DVD looks just like an ordinary compact disc, though a DVD can hold up to 25 times as much as a CD!! That's 18 gigabytes!! This gives sufficient room to hold a whole movie at twice the quality of VHS with theatre quality sound (better than CD-quality). Since it is on a disc, you can jump to any scene instantly, and you never require to rewind.

A DVD-ROM is a DVD disc for a computer. This means a multimedia encyclopaedia can have even more multimedia with much good quality (on DVD-ROM). You must have a DVD-ROM drive to use DVD-ROM discs. If you have a DVD-ROM drive, then you can also play DVD movies on your computer. Most of the systems with DVD-ROM can output the video and sound to your TV and home audio system, so you may not have to buy a divide DVD player. See also: CD-ROM
