Detailed explanation-1: -What does a client do when it has UDP datagrams to send? It just sends the datagrams. It queries the server to see if it is ready to receive data.
Detailed explanation-2: -User datagram protocol (UDP) operates on top of the Internet Protocol (IP) to transmit datagrams over a network. UDP does not require the source and destination to establish a three-way handshake before transmission takes place. Additionally, there is no need for an end-to-end connection.
Detailed explanation-3: -UDP does not provide error correction and is therefore an unreliable protocol. In other words, delivery of packets is not guaranteed. UDP datagrams are transmitted without provision for an acknowledgment. Because there is no virtual connection between sender and receiver, UDP is also said to be connectionless.
