my dad said it means it's working
CdRom - To read cd's CDR - To read and write CD's DVDrom - to read dvd's DVDR - To read and write dvd's Zip- Used like a floppy, but will store 100 Mb of storage Floppy - stores 1.44 Mb of data Hard Drive- where everything is saved There are tons more types of drives.. do a search on google for it
Floppy drives are not as necessary as they once were because the industry is moving toward storage media that can hold more data, such as CDs.The CD-ROM or optical drive. Floppy disk drives have stagnated in development; any off-the-shelf drive these days will support the highest commonly available capacity, 1.44 MB. Many people these days don't even use floppy disks.
Each IDE connector on the board supports two channels per. (Two drives) The combination of drives can vary. For instance, hard drive-cdrom, hard drive-hard drive, cdrom-cdrom, ect....ect.
No. A "system disk" is simply any disk which the computer can boot from and has an operating system installed on it. In most modern computer systems, the hard disk is normally the system disk. However most systems can also boot from a floppy disk, a cdrom, or even a USB thumb drive, providing of course that the media in question has the necessary system files on it. Many older systems did not have the ability to boot from the cdrom drive or USB drives. On these systems the only options were booting from the hard disk or floppy disk, so if the OS hadnt been installed to the hard disk yet (or it was broken) the only other option was the floppy disk.
if it is DVD or CDROM both,otherewise only one
They used to. The current 3.5" size and the Dynasaur 5.25" but both are becoming extinct and replaced by the cdrom's, flash drives, & smart cards.

As many as needed. In laptops/notebooks there is usually only one hard disk. In a desktop or server there could be potentially any number of disk drives. If you mean a CD/DVD drive the same applies.
The first two floppy drives, if present, are A: and B:. Then, the first active partition on the first hard drive is C: If there is a second physical hard drive, it would be D: ... additional partitions on the hard drives, if active, would get letters after that. The optical drive is normally lettered after the last hard drive partition. So, if you have a computer with 1 floppy, one hard drive with a single partition, and a CD Rom drive, the floppy would be A:, the hard drive would be C:, and the CDRom would be D: In more recent operating systems, however, you can re-arrange drive letters using the storage management tool; but the above is the "normal" arrangement.
A drive is a temporary storage device such as a Floppy disk device, Cdrom, DVD player or burner, Hard drive, flash drive, or memory reader. a D-drive is just a lettered drive designation. It could be any one of the drives listed above, or any number of other types of drives. Most system builders start with an A-drive and usually assign a Floppy drive to that letter. B drive letters are second floppy drive (if present), a C-drive letter is usually saved for a hard drive and D drive letter is usually used for CD/DVD/blue-ray drives, however, these designations are not exclusive and there is no hard rule as to what letters go with which drive types. There are any number of these designated letters, and different computers are built with any number of drives.
In the early take up period of computer cdrom drives, Pc's required an interface to drive the unit itself. Later on, the drives were created able to utilise the IDE interface.
It goes (Most room) Tape, DVD, CDROM, Floppy.
