User Datagram Protocol (UDP)
User Datagram Protocol (UDP) is a lightweight, connectionless transport-layer protocol that provides fast data transmission between programs without delivery or ordering guarantees. UDP operates over IP without a connection handshake, delivery confirmations, or retransmission of lost packets; it simply sends the data immediately. It is chosen for applications where transmission speed and timeliness matter more than perfection, such as live video streaming, voice calls, and online multiplayer gaming.
