CDs are for music while DVDs are for movies
The main difference between a CD driver and a DVD driver have to do with the protocols that operated individual programs.
CD Roms can only Read CD's such as VCD, Audio CD, mp3 CD.DVD Roms can read any CD's such as VCD, Audio CD, mp3 CD and also read DVD's such as DVD Video, DVD Audio & DVD mp3's.
In my experience, the laptops have slower drives in terms of read speed.
a CD is 700 megabytes and uses an infrared laser. a DVD is about 4.5 gigabytes and uses a red laser commercially Dvd's are for movies and new software and Cd's are used for music and older software
Diferen t between CD 750mb and DVD 850mb
CD-R is Compact Disk - Read CD-RW is Compact Disk - Read, Write
a CD drive plays music and a DVD drive plays movies.
CD offers capacity of about 700MB while DVD offers about 4GB space plus better sound and picture quality
A DVD has a higher capacity than a CD
DVD, short for Digital Versatile Disc, is also an optical medium to store digital data. A standard DVD can hold 4.7 GB of data. So DVD is widely used to store large files like video and movies. The capacity is the biggest difference between CD and DVD
They use the same technology and disc size. They differ in how dense the tracks are printed onto the disc and the format. The recorder and players have to have different lasers, to be able to read the data. DVD players are backward compatible with CDs.
A CD drive is an optical drive (a piece of hardware that reads Compact Discs). A DVD drive is an optical drive (a piece of hardware that reads DVD Discs). There are lots of optical drives that can read both DVDs and CDs, some can even 'burn' information onto blank discs. ___________________ From: TheAllKnowingEye
