Alternatively called an input/output interface, IOC, or PIOC for Peripheral input/output controller. The input/output controller is a device that interfaces between an input or output device and the computer or hardware device. The input/output controller on a computer is commonly on the motherboard.

Additionally, an I/O controller can allow for additional input or output devices for the computer. It can also be an internal add-on component that replaces a malfunctioning I/O controller on the motherboard.
