A '''device controller''' is a [[peripheral]] which is an intermediary between a computer (usually connecting to a [[bus]], although possibly the [[central processing unit|CPU]] directly) and some external device (often [[secondary storage]]).

The canonical pairing is a disk controller and a [[disk]] drive, although controllers are also found with [[magnetic tape]] drives, [[paper tape]] readers and/or punches, and numerous other kinds of devices.

Usually a single controller is able to handle multiple identical devices, thereby amortizing the controller's cost, since the external devices often include mechanical components, and are the thus slower than the all-electronic controller.
