Actually, it has to be a DVD-ROM drive. A CD or CD-RW drive won't do it. Most modern comps do have a DVD reader, but not all.
So:
If you have a computer with a DVD drive (the letters DVD will appear on the door of the drive), you're all set.
If not (even if you have a DVD player hooked up to your TV), you won't be able to play it.
But the content of the disk would probably fit onto a regular CD-R disk, so if you have a CD-R or CD-RW drive, there's a chance you could work something out.
