What is an advantage of UDP over TCP?
- UDP communication is more reliable.
- UDP communication requires less overhead.
- UDP acknowledges received data.
- UDP reorders segments that are received out of order.
Explanation: TCP is a more reliable protocol and uses sequence numbers to realign packets that arrive out of order at the destination. Both UDP and TCP use port numbers to identify applications. UDP has less overhead than TCP because the UDP header has fewer bytes and UDP does not confirm the receipt of packets.
