User Datagram Protocol (UDP) is a transport protocol layered on top of the Internet Protocol (IP). Use the UDP interface for reading and writing both binary data and ASCII data. You can read and write to servers, computers, instruments, and use applications such as streaming video and audio, point-of-sale systems, and other business applications.
