Explanation:
Detailed explanation-1: -UDP is desirable for protocols that make simple request and reply transactions because of its low overhead.
Detailed explanation-2: -UDP works by gathering data in a UDP packet and adding its own header information to the packet. This data consists of the source and destination ports on which to communicate, the packet length and a checksum. After UDP packets are encapsulated in an IP packet, they’re sent off to their destinations.
Detailed explanation-3: -DNS, TFTP, and many other protocols rely on UDP for their data transmission. UDP is a connectionless protocol. No connection needs to be established between the source and destination before you transmit data.
