User Datagram Protocol (UDP) is a connection-oriented protocol using a three-way handshake which is a set of initial steps required for establishing network connection. UDP supports retransmission of lost packets, flow control (managing the amount of data that is being sent), and sequencing (rearranging packets that arrived out of order). Example applications of UDP include transmission of text and image data.
