Answer
Short for User Datagram Protocol, a connectionless protocol that, like TCP, runs on top of IP networks. Unlike TCP/IP, UDP/IP provides a direct way to send and receive datagrams over an IP network.
It’s used primarily for broadcasting messages over a network. As UDP has no error reporting built in and contains no information to allow packets of information to be re-assembled, it can only work with a single packet. If the information you wish to transmit is larger than one packet then all but the first packet will be lost.
