A machine that
reads data from and
writes data onto a
disk. A disk drive rotates the disk very fast and has one or more heads that read and write data.
There are different types of disk drives for different types of disks. For example, a hard disk drive (HDD) reads and writes hard disks, and a floppy drive (FDD) accesses floppy disks. A magnetic disk drive reads magnetic disks, and an optical drive reads optical disks.
Disk drives can be either internal (housed within the computer) or external (housed in a separate box that connects to the computer).
