What is the Full Form of UDP protocol ?

UDP - User Datagram Protocol

The User Datagram Protocol is an opportunity protocol to TCP, that is used for low-latency and loss tolerating connections. Both, UDP and TCP is living on the 'transport layer' of the TCP/IP protocol suite. They are one of the center protocols of the TCP/IP protocol suite.

There are 2 predominant features of the UDP protocol. First, it assigns port quantity to each process and forwards the incoming packet to that port. Second, UDP protocol exams the ordering of incoming frames, that the whole message arrives intact and in-order.

UDP protocol does not send any sort of manage information together with the IP Datagrams, there by way of lowering the "size" of the UDP message to a bigger volume. 

Working of UDP protocol
UDP is a connectionless protocol as oppose to TCP. This approach the receiver don't renowned the received frames, so even though the body get lost at some stage in the transmission, sender won't be knowledgeable.

Another issue is that, as oppose to TCP, a UDP message do not observe any specific order, the messages that arrives first are the ones to be displayed first. These capabilities of UDP protocol makes it appropriate for a restrained and unique form of packages like video conferencing, IP telephony, media streaming and so forth. 

Difference between UDP and TCP
The primary difference between TCP and UDP is that, TCP is a connection-oriented protocol i.E, the receiver is stated about the status of the message - acquired or lost. In case of UDP no such synchronization is maintained, the sender might not be informed of the lost or corrupted frames.
