The raspberry Pi has a 40 pin connector that provides access to a level of connection not generally available to the PC world. This allows Digital devices to be connected to a Raspberry Pi and the Pi can both receive and transmit information to these devices as digital Data. +3.3V or 0v in electrical terms.

This connector will probably exist as a standard for a considerable length of time, such is the electronic infrastructure that has grown around it. Indeed competitor boards, would dare use anything else so it's become ubiquitous, in a similar fashion to the IBM edge connectors carried on long after the company had stopped making PC's themselves.
