UPnP (Universal Plug and Play) A Microsoft initiative that extends the PnP specification to networks. UPnP enables a PC to automatically recognize the presence of a new peripheral hardware device as it is connected to a network, locate the necessary support software (e.g., driver), and configure the device interface. UPnP is aimed primarily at home and small office users who need to network devices such as personal digital assistants (PDAs) and digital cameras. See also PnP. |
