A new form of data storage compared to CD and will in the future probably overtake CD-ROM use because a DVD can store 4 GB of data which is 6 times the size of a regular CD. Because DVD is now becoming the most popular form to buy films and movies on you can soon expect to find computer software applications and games being more available on DVD than CD. DVD drives for your personal computer are now also becoming a lot cheaper to purchase. DVD-ROM's also provide backwards support for CD's. |
