Which of the following transport layer protocols is connectionless and does not provide reliability, flow control, or congestion control mechanisms?
HTTP
UDP
TCP
ICMP
The correct answer is UDP. The User Datagram Protocol (UDP) is a connectionless transport layer protocol that prioritizes speed and low overhead. It does not provide reliability features like acknowledgements, nor does it manage data flow with flow control or congestion control. In contrast, TCP (Transmission Control Protocol) is a connection-oriented protocol that provides all of these features. ICMP is a network layer protocol used for diagnostics, and HTTP is an application layer protocol that typically runs over TCP.
