how is CD - ROM different from DVD
Answers
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. ... Speed is hardly noticeable between a CDROM and a DVD when writing full discs due to the higher capacity of DVDs.
Answer:
A Digital Versatile Disc or Digital Video Disc (DVD) is similar to a CD-ROM in that you can only read data from it. The main difference is that the DVD can store much more data than a CD-ROM, CD-R, or CD-RW. ... A DVD-R can only record data once, then the data becomes permanent on the disc
The major difference is the capacity. Compact Discs (CDs) can store only upto 700 MB while Digital Versatile Discs(DVDs) can store upto 4.7 GB. Other than that, they differ in read/write speeds. It is the speed at which data is read from or written on the disc.
