Correct answer: Lower overhead than TCP, Applications can use checksums to verify data integrity.
Why this is the answer
UDP (User Datagram Protocol) offers lower overhead than TCP because it is a connectionless protocol. It doesn't establish a connection, manage flow control, or provide guaranteed delivery, which reduces the header size and processing required. This makes it faster for applications where speed is more critical than reliability, like streaming video or DNS lookups. While UDP itself doesn't guarantee data integrity, it includes an optional checksum field. Applications can choose to use this checksum to verify that the data has not been corrupted during transmission. TCP provides retransmission for lost packets, uses a control field for a three-way handshake, and maintains connection state for stability, but these are not UDP features.
