Which of the following is incorrect about User Datagram Protocol?a)UDP...
Concept:
The User Datagram Protocol (UDP) is a network communication protocol that makes it easier to send and receive messages between computers. It's a replacement for the Transmission Control Protocol (TCP) (TCP). It is sometimes referred to as UDP/IP in a network that uses the Internet Protocol (IP).
Option 1: UDP is an unreliable transport protocol.
True, UDP is an unreliable protocol because it does not provide error correction. To look at it another way, packet delivery is not guaranteed.
Option 2: There is no window mechanism in UDP.
True, UDP is a simple but insecure transport protocol. There is no window mechanism because there is no flow control.
Option 3: There is a robust error control mechanism in UDP.
False, In contrast to TCP, UDP does not require checksum calculation. UDP does not provide any error or flow control. As a result, UDP error reporting depends on IP and ICMP. As a result.
Option 4: The receiver may overflow with incoming messages.
True, UDP is a very simple protocol. It lacks a flow-control mechanism. The receiver may become overburdened with incpming messages. If this service is required, the process using UDP should provide it.
Hence the correct answer is there is a robust error control mechanism in UDP.
