Drive Definition, What is a Drive

The A: Drive is a physical drive located on IBM or PC compatible computers. The A: drive is a drive letter that is almost always used for the 3.5-inch floppy disk drive today, but an older computer may be the 5.25-inch drive.

The A: drive is usually the first boot-able drive on IBM compatible computers that helps enable users to use boot-able floppy diskettes to fix and repair their computer.

B: Drive is also another commonly known disk drive just like the A: drive. I know this information is a bit archaic, but never-less, you should at least now about the old school parts of a PC.
