What is the difference between a CD drive, CDRW, Combo, DVD, and all that stuff?
All these are optical drives. This was the part you probably already knew. The difference between them is what they can read and write. The table below shows which is which. The leftmost column lists the types of drives, while the four columns on the right indicate whether you can read or write that type of disc. When writing DVDs, please consult the box your drive came in or other documentation regarding which specific types of DVD you may use.
