Plug-and-Play

Refers to the ability of a computer system to automatically configure expansion boards and other devices. You should be able to plug in a device and play with it, without worrying about setting DIP switches, jumpers, and other configuration elements. Since the introduction of the NuBus, the Apple Macintosh has been a plug-and-play computer. The Plug and Play (PnP) specification has made PCs more plug-and-play, although it doesn't always work as advertised.
