UDP (User Datagram Protocol) is a core networking protocol. Below are statements about UDP, with the false one identified:
1. UDP guarantees delivery of data packets. – False. UDP does not guarantee delivery, ordering, or error checking. It’s a connection-less protocol that sends packets (datagrams) across the network without ensuring that they reach their destination.
2. UDP enables a faster transmission of data compared to TCP. – True. Because it lacks the overhead of ensuring packet order, delivery, and error checking that TCP (Transmission Control Protocol) implements, UDP can transmit data more quickly in situations where these features are not necessary.
3. UDP is used for applications that require fast, efficient transmission, like gaming or live streaming. – True. The efficiency and reduced latency of UDP make it ideal for time-sensitive applications where some loss of data is acceptable compared to the need for speed.
4. UDP provides error correction mechanisms. – False. While UDP does include a checksum to help identify data corruption, it does not inherently correct errors; it merely allows the application to detect corrupted packets.
5. UDP supports broadcasting and multicasting. – True. UDP supports both broadcasting (sending data to all on a network) and multicasting (sending data to a group of subscribers), which is not inherently supported by TCP.
So, the statement that is false with respect to UDP is: “UDP guarantees delivery of data packets.”
