UDP and TCP protocols

[Xmen]

Hi,
I have always jumble this words. What is UDP ? is it any protocol? what are difference between UDP and TCP protocols?

UDP (User Datagram Protocol) is protocols of the Internet Protocol Suite.The message sent by the network computer called Datagram. UDP is faster and more efficient, for applications which is no need guaranteed delivery.It is useful for servers that answer small queries from huge numbers of clients.UDP supports packet broadcast and multicasting.
TCP stands for Transmission Control Protocol.It is often referred to as TCP/IP due to the importance of this protocol in the Internet Protocol Suite.CP operates at a higher level, concerned only with the two end systems.TCP provides reliable, sequential delivery of a stream of data from one program on one computer to another program on another computer.TCP controls message size, the rate at which messages are exchanged, and network traffic congestion.

TCP and UDP is types of internet protocol and both are having very different uses.UDP(User Datagram Protocol) is simpler message-based connectionless protocol.With UDP you send messages across the network. It's Unreliable, whenever you send a message you don't know if it'll get there, it could get lost on the way. There no guaranteed delivery.
TCP(Transmission Control Protocol) is connection-oriented protocol, a connection can be made from client to server, and from then on any data can be sent along that connection. It's reliable , when you send message you know it will get there unless the connection fails completely. If it gets lost along the way, the server will re-request the lost part. it deliver the message in ordered manner.

TCP stand fpr Transmission Control Protocol.UDP stands User Datagram Protocol.
It's one of the core protocols of the Internet protocol suite. Both TCP and UDP work at transport layer.TCP is connection-oriented protocol where as UDP is connectionless protocol. TCP is reliable then UDP. The message send on tcp it get in ordered, while on UDP it not in ordered. so in every manner TCP is more secured and more reliable then UDP
