False Statement: UDP is connection-oriented.

UDP stands for User Datagram Protocol, which is a transport layer protocol in the OSI model. It is one of the two main protocols used for internet protocol suite, with the other being TCP (Transmission Control Protocol).

Explanation:

UDP:
- UDP is a connectionless protocol, which means it does not establish a connection before sending data. It is a simple, lightweight protocol that is used for quick and unreliable transmission of data.
- UDP does not guarantee delivery, ordering or error-checking of data packets. It provides a best-effort delivery mechanism, where the sender simply sends the data packets without any acknowledgments or retries.
- UDP is often used for real-time applications such as video streaming, voice over IP (VoIP), online gaming, where a small delay is preferable over reliability.
- UDP has a lower overhead compared to TCP, as it does not have the additional mechanisms for reliability and ordering of data packets.

Explanation of False Statement:
The false statement in the given options is "a) Connection-oriented". UDP is not a connection-oriented protocol. It does not establish a connection between the sender and receiver before transmitting data. Instead, UDP allows the sender to simply send the data packets to the receiver's IP address and port number without any prior setup. This lack of connection establishment makes UDP a faster and more lightweight protocol compared to TCP, but it also makes it less reliable.

Summary:
To summarize, UDP is a connectionless, unreliable transport layer protocol that provides a best-effort delivery mechanism. It is widely used for real-time applications where a small delay is acceptable, and a lower overhead is desired.
