What interface that controls a peripheral device is.

An adapter pattern is a structural design pattern which translates one interface for a class into a compatible interface.

An expresscard is an interface that allows peripheral devices to be connected to a computer usually a laptop. An expresscard can be used as an adapter or a digital tv turner

It can also be called a network interface controller, network interface card, network adapter, and LAN adapter.

So the link between the processor and the peripheral is complete :-)!
