A special-purpose chip and circuitry that directs and controls reading from and writing to a computer's disk drive. Also called a hard disk controller (HDC).
When connected to a disk drive via a ribbon cable, allows communication between the disk drive and the rest of the computer.
The electronic circuitry that controls and manages the operation of floppy or hard disks installed in the computer.
In the multipathing subsystem of VxVM, the controller (host bus adapter or HBA) or disk array connected to the host, which the Operating System represents as the parent node of a disk.
(computer science) a circuit or chip that translates commands into a form that can control a hard disk drive
a collection of hardware and software routines that translate the file system commands expressed in logical terms into hardware-specific commands expressed in a protocol understood by the physical drives
The chip or circuit that controls the transfer of data between the disk and buffer. (See also disk drive controller and interface controller).
The hardware that controls the writing and reading data to and from and to a disk drive. It can be used with floppy disks or hard drives. It can be hard-wired or built into a plug-in interface board.
A hardware circuit which translates instructions about disk access from the operating system to the physical disk. This provides a layer of abstraction that means that an operating system does not need to know how to talk to the many different types of disks, but only needs to know about the (comparatively low) number of types of disk controller. Common disk controller types are IDE and SCSI.
A hardware component that is responsible for controlling one or more disk drives.
Electronic circuitry, often found on an expansion board, that controls disk operations and the flow of data to and from the computer to one or more disk drives.
Special-purpose chip and associated electronic circuits that control the transfer of data, instructions, and information from a disk to the rest of the computer. Sometimes referred to as an interface. 7.13
The disk controller (or "hard disk controller") is the circuit which allows the CPU to communicate with a hard disk, floppy disk or other kind of disk drive.
