UDP is said to be transaction-based, because it focuses only on the transaction of data. Not on the connection like TCP does.
. A Explain the overview of UDP messaging.
Routers Drop a lot of UDP packets

DHCP is a connectionless protocols. In general, any protocol that is based on TCP port alone is a connection-oriented protocol while any protocol that is based on UDP port alone is a connectionless protocol. And a protocols that can work on both TCP and UDP port can be either a connection-oriented or a connectionless protocol depending upon the which protocol is used (TCP or UDP). For checking other protocols if they are connection-oriented or connectionless check http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
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.
