DVD/CD
 

Please excuse my ignorance but can someone tell me the difference between DVDrom and CDrom?

Speaking to some bloke in a well known computer game shop, told me most PC games are now DVD based. I asked him, "what the hell does that mean", but he didn't know. I picked up a couple of PC game boxes and sure enough the letters DVD are in the place where CDrom used to be. I have no idea what this is all about. Does it make the game run faster or something? Do I need special hardware to run a DVD game or will it run in my CDrom/ DVD player already built into my computer?

DVD capacity 4.3GB, CD capacity 700mb, 1 DVD saves producing a game on 6 CD's.

I've always wondered, since recordable DVDs and CDs both use a laser to change the colour of a dye, but the DVD at a higher resolution - would it not be possible to burn a DVD at a lower resolution (700mb) so that it could be used in a CD player? Not quite sure why you'd want to do this, but I'm bored...

you'll need to read the comparison here the only thing that is the same is the physical size of the disks.

Thanks, so it's just a size thing then? Will my CDrom read the DVD software? It has an inbuilt DVD player which isn't working, do I need to get this fixed in order to play DVD based software?

A DVD player can read a CD, but a CD player cannot read a DVD. The physical arrangement of the tracks are closer together on a DVD, so much so, that a CD player would try to read many tracks at the same time if it could, as the CD player uses a much wider beam to read a CD than a DVD player uses to read a DVD.

Then there is Blue-Ray......

NO

Yes, and Yes
