(26.) Client will start communication and establish connection. It will send the list of numbers to the TCP server.

(27.) TCP server, which can handle maximum 3 clients concurrently, will accept the list and send back the smallest number. Server will terminate this is a connection once the number is sent.

(28.) How does a DNS server work ? Explain with the help of a suitable example for recursive and iterative solutions.
