With Plug and Play you can configurea new add-on board entirely from software, without moving jumpers or changing DIPswitches on the board.A Plug and Play ready system is one in which cooperation takes place between thehardware, the operating system, device drivers, and applications. Most add-on boardsneed system resources (DMA channels, interrupts, I/O space) in order to interact with
