UDP Sockets

UDP is short for User Datagram Protocol that (just as TCP) runs on top of IP. It is typically used in conjunction with IP (Internet Protocol): UDP/IP. The difference with TCP is that UDP doesn't guarantee delivery of packets. On the other hand, it doesn't have the TCP overhead of setting up a connection and acknowledging packets. UDP is mostly used in streaming video and audio data to one or more destinations (multicast). Also, check out the parent category if you don't find what you are looking for.
