What is the difference between CDs and DVDs?

Answer 1

CDs have a storage capacity of around 700MB whereas standard DVDs can store 6 times as much information - around 4.5 GB - or even more on double layered DVDs. This means that video content (around 3GB for a movie) will fit onto a DVD but would be too large for a CD.

Answer 2

CD and DVD are 2 different types of media storage. DVD's can hold far more data on them due to the fact that the laser used to read them is much narrower.

CDs can hold a maximum of 700mb or about .7GB

For DVDs, there are currently two types available: DVD_+R/RW which holds 4.3 Gb DVD-+R/RW dual layer (2 layers of silicon to put data on inside the disk)which holds 7.2 Gb There is also writable disks that hold 4.7Gb and also, some company's disks can hold more than others but the difference is minimal

There is also Blu Ray disks now that can hold between 50Gb and 80Gb
