Which transport protocol is connectionless-oriented?

Which transport protocol is connectionless-oriented?

• A. File transfer protocol (FTP).
• B. User datagram protocol (UDP).
• C. Transmission control protocol (TCP).
• D. Simple mail transfer protocol (SMTP).

Answer: (B)

The User Datagram Protocol (UDP) is identified as a connectionless transport protocol because it does not establish a dedicated end-to-end connection before transmitting data. In the case of UDP, data packets are sent independently without requiring any prior communication or handshake between the sender and receiver. This characteristic allows for faster transmission, as there is less overhead in managing connections. UDP is typically used in applications where speed is more critical than reliability, such as online gaming, video streaming, or VoIP, where occasional data loss is acceptable and can be tolerated without impacting overall performance. Its connectionless nature means that it doesn't guarantee the arrival of packets or their order, which is in contrast to connection-oriented protocols like TCP, which ensure reliable delivery of data through a more complicated setup process involving connections and acknowledgments. Understanding UDP's connectionless nature helps clarify its role in network protocols and applications where quick data delivery is prioritized over reliability.
