difference between data disc and cd-rom
Best Answer: A Compact Disc (also known as a CD) is an optical disc used to store digital data, originally developed for storing digital audio. A data disc is a method/end product of storing information onto a CD or DVD(if you choose), basically imagine a floppy disc but with a hell of a lot more storage capability.
Difference Between CDROM and DVD. DVDs and CDROMs are both optical storage devices that have a lot of use; the most prominent of which is the distribution of content like movies, music, software, and such. The biggest difference between a CDROM and a DVD is their capacity. A CDROM typically holds 700MB of data per disc while a DVD can hold 4.7GB on a single layer. Dual layer and double-sided DVD discs push this to a maximum of 17GB. This is also the main reason why the CDROM was superseded by the DVD. Another advantage of a DVD is its much faster data transfer speeds.
