Universal Plug and Play (UPnP) is a set of networking protocols that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices to seamlessly discover each other's presence on the network and establish functional network services for data sharing, communications, and entertainment. UPnP is intended primarily for residential networks without enterprise class devices.
The UPnP technology is promoted by the UPnP Forum. The UPnP Forum is a computer industry initiative to enable simple and robust connectivity to stand-alone devices and personal computers from many different vendors. The Forum consists of over eight hundred vendors involved in everything from consumer electronics to network computing.
The concept of UPnP is an extension of plug-and-play, a technology for dynamically attaching devices directly to a computer, although UPnP is not directly related to the earlier plug-and-play technology. UPnP devices are "plug-and-play" in that when connected to a network they automatically establish working configurations with other devices.

Famous quotes containing the words universal and/or play:
“We can most safely achieve truly universal tolerance when we respect that which is characteristic in the individual and in nations, clinging, though, to the conviction that the truly meritorious is unique by belonging to all of mankind.”

“The last act is bloody, however pleasant all the rest of the play is: a little earth is thrown at last upon our head, and that is the end forever.”
