The User Datagram Protocol (UDP) is one of the core protocols of the Internet Protocol (IP) Suite in the transport layer. The protocol’s primary purpose is for the use of sending messages (datagrams) between two endpoints across the Internet without the need of a pre-existing data path from prior communication between the endpoints. This is what is referred to as connectionless communication and is ideal in situations where error-checking and error-correction are not needed between two endpoints. In these scenarios, the datagrams can be sent between the two endpoints faster than using the Transmission Control Protocol (TCP) and Stream Control Transmission Protocol (SCTP) as the overhead generated from error-checking and error-correction is no longer a factor. This makes UDP very popular and a very optimal solution in these types of situations as it would be more preferred than its counterparts.
