A Digital Versatile Disc (DVD) uses new optical storage technology to hold more data than a Compact Disc (CD).
DVDs are designed to be read from a narrower beam of laser light than CDs so this allows more information to be stored in the same amount of space. There are also more efficient formatting methods that help as well.
yes a DVD can definitely store more data compared to a normal CD.
Yes, but I'm not sure exactly how much more.
normally they put more space on a dvd because it supports video w/ audio while a cd is audio only
Yes. Blu-Rays hold up to 5 times more data than a standard DVD
yes
DVD
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
All of the data on a CD can be recorded on a DVD. DVD s hold much more data than CD s. And as such, all the files may fit on a DVD unless they were compressed on the CD and then some how they become decompressed when they are recorded on the DVD. A CD has data capacity of 700MB. A single layer DVD has a capacity of 4.7GB and a double layer one has capacity of 8.5GB. So data of at least 6 CDs can be copied on a single 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.
