Which protocol is characterized by one-way communication without verifying data transmission?

• A. Transmission Control Protocol (TCP)
• B. Hypertext Transfer Protocol (HTTP)
• C. User Datagram Protocol (UDP)
• D. File Transfer Protocol (FTP)

Answer: (C)

The User Datagram Protocol (UDP) is characterized by one-way communication that does not include any mechanisms to verify whether data has been successfully transmitted. UDP functions by sending messages, called datagrams, directly to the recipient without establishing a connection or ensuring that the data arrives intact. This is in contrast to protocols like TCP, which establish a reliable connection and implement various error-checking methods to confirm that the data sent is received correctly. The nature of UDP makes it suitable for applications where speed is prioritized over reliability, such as online gaming or streaming, where a few lost packets may not significantly impair the user experience. As a result, UDP's simplicity allows for lower latency, making it a preferred option in scenarios where timely delivery is more critical than perfect accuracy.
