I know this may seem like stupid questions, but Im looking to buy a expensive laptop and I want to be sure I understand what the specs mean. I need a dvd burner, and I was wondering if the laptops say that they have this, it means they are dvd burners. What does 24x/8x/8x/8x DVD+CD-RW combo drives mean? Does this mean it is also a dvd burner as well as a cd burner? Also what does DVD/CD-RW combo mean?
