What is UDP?
UDP (User Datagram Protocol) sends data without setting up a connection first and without checking whether it arrives. It skips the overhead of acknowledgments and retransmissions, which makes it faster than TCP but less reliable. Applications like video streaming, online gaming, and DNS lookups use UDP when speed matters more than guaranteed delivery.
