Explain the purpose of the following protocols:
(a) TCP/IP
(b) UDP
(a) TCP/IP
(b) UDP
Show Hint
Solution and Explanation
(b) UDP (User Datagram Protocol): UDP is a connectionless protocol used within the TCP/IP suite. Unlike TCP, UDP does not establish a connection before sending data, nor does it guarantee delivery, ordering, or error correction. It simply sends packets called datagrams to the recipient without acknowledgments. This reduces overhead and latency, making UDP suitable for applications where speed is critical and occasional data loss is acceptable, such as streaming media, online gaming, and voice over IP (VoIP).
