DVD-ROM means it can read DVDs, but not write to them.
CD-RW means it can read and write CDs - RW means it can do rewritables.
DVD+-RW means it can read and write DVDs - RW means it can do rewritables.

1) Is a DVD reader only. Reads at 16x
2) Can read and write CDs only. Reads at 48x
3) Can read and write CDs, can read DVDs. Reads at 48x
4) Can read and write DVDs (also CDs), can do Dual Layer DVDs as well

Answer 2

1. 16x max. DVD-ROM-How fast it can read DVD's
2. 48x32x48x CD-RW- How fast it can read CD's and can write CD's
3. 48x32x48x CD-RW / 16x DVD-ROM Combo Drive- Both 1 & 2 put together, but cannot burn DVD's
4. 16x DVD +/- RW 6 with Dual Layer Write Capability- Does all off the above, but can write DVD's with or without Dual Layer. Dual Layer is pretty much doubling the amount of space on a DVD disc, but you will need a disc that supports Dual Layer
