A Digital Versatile Disc (DVD) uses new optical storage technology to hold more data than a Compact Disc (CD).
Dvd is better than CD because the dvd can store more data than the CD
A DVD stores significantly more data than a CD can.
A (DVD?) can hold 4.7 GB while a CD can hold 700 MB; this is about 6.7 times more.
DVD
A DVD is more preferable than CD for its higher storage capacity than CD. Generally, a CD can hold up to 700 MB whereas a DVD can hold up to 4.7 GB. DVD is not only superior than CD in storage capacity, but also it is superior in requirement. It has been experienced that some system softwares require more than one CD or even one complete movie requires two or three CDs for storage. The use of DVD can overcome these problems as one DVD can be used to store the information of a number of CDs. A DVD requires a DVD combo drive or a DVD player which allows to read CDs as well as DVDs. Thus, a DVD is more preferable than a CD.
The DVD has a greater density. The laser can read finer grooves.
CDs and DVDs share the same physical format but the DVD stores more data that a CD. It does this a much finer set of optical tracks on the disc than the CD has. In a similar way, Bluray discs hold far more data than a DVD.
A DVD holds around six times as much as a CD. Also, some USB drives and almost all hard drives hold WAY more than a CD.
A regular 700mb cd will fit about 6.7 CDs onto one regular 4.7GB dvd
any cd can hold video data but it will not be in DVD format, it will be in VCD, MPEG, AVI etc. DVD format, which is VOD, has large file sizes.
No. Audio CD's hold audio only while DVD's hold movie formats, such as; .avi, .wmv, .mpeg-4, .mpeg-3, etc.
There was too much info for regular cd, DVD's hold alot more info making it so that they don't have to make cases for 10 cd,s for one game when they can fit it on just 2 DVD's
