disk cache: A technique that speeds up processing. Each time your
application receives data from a disk, a special program stores the
data in a reserved area of memory (RAM). When the application
next requests data, it looks for it first in the disk cache. Since reading
from and writing to memory is quicker than using a disk drive, this
can considerably improve system performance.
disk drive: The device that reads and writes information and programs on
a diskette or hard disk. It rotates the disk at high speed past one or
