What is the User Datagram Protocol (UDP) ?

The User Datagram Protocol (UDP) is a communication protocol that, like TCP, runs on top of IP networks. The protocol was designed by David P. Reed in 1980 and formally defined in RFC 768. UDP uses a simple connectionless transmission model with a minimum of protocol mechanism. It is used primarily for broadcasting messages over a network. UDP uses the Internet Protocol to get a datagram from one computer to another but does not divide a message into packets (datagrams) and reassemble it at the other end. UDP doesn’t provide sequencing of the packets that the data arrives in.
