User datagram Protocol (UDP) is one of the group of Internet Protocols. It operates by sending messages without receiving a reply to acknowledge receipt or correctness of contents as is provided by TCP/IP. As such it is widely used for applications such as internet based radio and video transmission, where a device simply ‘listens’.
This provides a means of sending data without expecting a response. Hence it is more efficient in the correct application. the data contained is application independent.
