Which of the following is an advantage that UDP has over TCP?

The correct answer is C. UDP is faster than TCP.. UDP (User Datagram Protocol) is faster than TCP because it is connectionless and has no overhead for establishing connections, acknowledgments, sequencing, or retransmission of lost packets. This makes UDP ideal for time-sensitive applications like video streaming, VoIP, DNS look

Explanation

UDP (User Datagram Protocol) is faster than TCP because it is connectionless and has no overhead for establishing connections, acknowledgments, sequencing, or retransmission of lost packets. This makes UDP ideal for time-sensitive applications like video streaming, VoIP, DNS lookups, and online gaming where speed matters more than guaranteed delivery. TCP is connection-oriented (not UDP), TCP is more reliable (not UDP), and TCP makes a 'best effort' with guaranteed delivery mechanisms - not UDP. UDP's speed advantage comes precisely from the reliability and connection features it lacks.
