What is the difference between a CD-ROM and a DVD-ROM?
Both are information storage discs that look very similar, but they are not identical. The CD-ROM format disc is an older technology, is readable on virtually every computer in use today, and can hold enough information for a two hour video in MPEG-1 format. DVD-ROMs are newer, but becoming increasingly common, and will eventually supplant CD drives in all computers. DVD-ROMs hold quite a bit more information than a CD-ROM, the equivalent of a full day’s deposition video. One disc is much more convenient than four.
