Discuss the UDP protocol.
What will be an ideal response?
UDP is an unreliable, connectionless datagram protocol. The main task of UDP is to make a simple and fast transport of data available through the network.
In this case, "unreliable" means that UDP has no mechanism to guarantee the delivery of a datagram. Applications that use UDP must implement their own routines on the application layer for guaranteeing the correct transmission of data.
"Connectionless" means that no computer-to-computer connection is established for transmitting UDP datagrams. Instead, UDP datagrams are sent by the sender without the destination machine making any further checks.
