disk controller
(Or "hard disk controller", HDC) The
circuit which allows the CPU to communicate with a hard
disk, floppy disk or other kind of disk drive.
The most common disk controllers in use are IDE and SCSI
controllers. Most home personal computers use IDE
controllers. High end PCs, workstations and network file
servers mostly have SCSI adaptors.
