This User Datagram Protocol (UDP) is defined to make available a datagram mode of packet-switched computer communication in the environment of an interconnected set of computer networks. This protocol assumes that the internet Protocol IP is used as the underlying protocol. This protocol provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection are not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the Transmission Control Protocol TCP. l

UDP port 123. (UDP is a connectionless protocol that sacrifices reliability for speed and bandwidth).

DNS uses both TCP and UDP, also a lot of online chats use UDP. I think even when you want videos on YouTube UDP is used to deliver video and audio.
UDP is a layer 4 (transport) protocol.

UDP is a connectionless protocol, so there is no session to close. UDP is not expecting any particular packet, so opening and closing via UDP is not necessary.
1. IP works at network layer, UDP works at transport layer. 2. UDP carries application data, IP carries TCP segments or UDP datagrams.
the main difference between UDP and TCP is that UDP is not a reliable protocol.

UDP and ports 67 and 68.
UDP typically should not be used where quality (not speed) is desired.
UDP is alot faster than TCP. So if its realtime obviously it has to be fast, thus UDP. The only problem is UDP isn't as reliable or as secure as TCP. But it does have the speed advantage.
