UDP

User Datagram Protocol, one of the core internet protocols. A stateless protocol that is often used in such applications as videoconferencing and online gaming, where data must arrive quickly, and data that arrives late is worthless. UDP doesn't have the handshake overhead of TCP to establish connections, and does not have features like flow control and reliability. The benefit of this smaller feature set is quicker data transmittal, and lower total overhead, hence its common usage in the aforementioned applications
