UDP versus TCP. (User Datagram Protocol versus Transmission Control Protocol). UDP provides unguaranteed, connectionless transmission of data across an IP network. By contrast, TCP provides reliable, connection-oriented transmission of data.

		UDP versus TCP (continued).
		Both TCP and UDP split data into
		packets called “datagrams.” However,
		TCP includes extra headers in the
		datagram to enable retransmission of
		lost packets and reassembly of packets
		into their correct order if they arrive out
		of order. UDP does not provide this.
		Lost UDP packets are unretrievable;
		that is, out-of-order UDP packets
		cannot be reconstituted in their proper
		order..
		Despite these obvious disadvantages,
		UDP packets can be transmitted much
		faster than TCP packets -- as much as
		three times faster. In certain
		applications, like audio and video data
		transmission, the need for high speed
		outweighs the need for verified data
		integrity. Sound or pictures often
		remain intelligible despite a certain
		amount of lost or disordered data
		packets (which appear as static).
