Which protocol provides connectionless communication with minimal overhead?

Correct Answer: B) UDP

UDP (User Datagram Protocol) is a connectionless transport-layer protocol that provides end-to-end communication with minimal overhead. It does not establish a connection before data transmission and has a small header size, making it faster and more lightweight than TCP.

TCP is connection-oriented and involves additional overhead for connection establishment, acknowledgments, and reliability. IP is responsible for addressing and routing at the network layer, while HTTP is an application-layer protocol.

Hence, UDP is the protocol that provides connectionless communication with minimal overhead.
