A ZiP drive CAN hold more but most DO NOT hold as much as DVD'd 4.7 Gb
the USB holds more information
is printer & DVD is volatile memory
A Blu-Ray DVD (50GB) holds more information than a DVD (4.7GB) which holds more information than a CD (700MB).
DVD by far. A DVD can store 4.7 gigabytes of data. A floppy disk can store 1.44 megabytes of data. 1000 megabytes = 1 gigabyte.
i don't know thats why i am asking you?
Your CD/DVD player is a Read Only Memory drive.
A CD holds about 700 MB. A DVD holds about 4.7 GB, or more for a dual-layer and/or double-sided DVD. You can now get USB thumb drives with capacity greater than a DVD.
Laptops will give you more ability. You can get a DVD player with it and more memory and hard drive space. If you need something that is very small and portable and do not need a DVD then choose a netbook.
DVD
no. You have processor, memory and input/output. Storage would be memory, hard drive, DVD.
A DVD holds around six times as much as a CD. Also, some USB drives and almost all hard drives hold WAY more than a CD.
If you have just installed a new DVD drive and its drivers, it should appear in 'My Computer'. This holds for Linux and Windows OS's.
