UDP (User Datagram Protocol)

Definition

UDP is a connectionless protocol that allows data to be sent across networks without establishing a dedicated connection. It provides fast transmission but does not guarantee delivery or order of packets.

Analogy

Imagine UDP as sending postcards through regular mail. You can quickly send multiple postcards without worrying about establishing connections or waiting for acknowledgments. However, there's no guarantee that all postcards will arrive or arrive in order.
