Not Received Or Not Delivered

The server is just yeeting responses into the void and hoping for the best! UDP (User Datagram Protocol) is basically the networking equivalent of throwing paper airplanes out a window and not caring if they reach their destination. Unlike its responsible older sibling TCP, UDP doesn't wait for acknowledgments or bother with retransmissions. It's the digital manifestation of "fire and forget" – perfect for streaming, gaming, and situations where dropping packets is preferable to waiting. The diagram perfectly captures how the server just keeps blasting responses without checking if anything arrived. Hey, did you get my packet? Who knows! Who cares!
