Which one is a connectionless transport-layer protocol that belongs to the Internet protocol family?

Correct option is B

UDP is a connectionless transport-layer protocol that provides fast and lightweight communication without establishing a connection. It is suitable for real-time applications requiring low latency.
Information Booster
1. Definition: UDP transmits data without establishing a connection, reducing overhead.
2. Characteristics:
· No guaranteed delivery or error correction.
· Suitable for applications like video streaming, gaming, and DNS.
3. Comparison with TCP:
· TCP ensures reliable, ordered delivery with error correction.
· UDP prioritizes speed and efficiency over reliability.
4. Applications: Real-time applications like VoIP and online multiplayer games.
5. Advantages: Low latency, minimal overhead, and multicast support.
Additional Knowledge
· TCP is connection-oriented, ensuring reliable communication.
· Routing Protocol (RP) operates at the network layer, not the transport layer.
· Datagram Control Protocol (DCP) is not a standard protocol in the Internet protocol suite.
