a. Consider a network comprising three nodes A (at Lahore), node B (at Karachi), and node C (at Multan) connected to the internet. The Web Server is in Peshawar and the DNS Server is in Quetta. [10] Node A in Lahore opens www.google.com in the browser. Do we need the DNS Server to open the website? b. Before HTTP data can be sent or received from node A to the Web Server, what must be established first? How does the webserver in Peshawar differentiate between the connections, if all three nodes (A at Lahore, B at Karachi, and C at Multan) opens www.google.com in their respective browser? d. If the DNS Server in Quetta goes down while transferring data between the web server and the host, will the communication be disrupted between the Web Server and nodes? How does the Web Server differentiate between the communications if node C in Multan opens two instances of www.google.com website? c. e
