What is a key characteristic of UDP?

• A. Ensures all packets are delivered
• B. Offers a reliable data stream
• C. Does not verify data integrity
• D. Uses connection-oriented communication

Answer: (C)

A key characteristic of UDP, or User Datagram Protocol, is that it does not verify data integrity. This means that when data is sent over UDP, there is no mechanism to ensure that the packets arrive correctly or at all. Unlike TCP, which is a connection-oriented protocol that ensures reliable data delivery and checks for the integrity of packets with acknowledgments and retransmissions, UDP is connectionless and simply sends packets without checking if they have been received or if they are in the correct order. This lack of integrity verification is what makes UDP faster and more efficient for certain applications, such as video streaming or online gaming, where speed is often more critical than reliability. Applications using UDP must handle any necessary error checking and correction themselves, leading to a trade-off between speed and reliability. This is why the ability of UDP to transmit data without verifying its integrity is considered a defining characteristic.
