Suppose you walk into a room, connect to Ethernet, and want to download a web page. What are all the protocol steps that take place, starting from powering on your PC to getting the web page? Assume there is nothing in our DNS or browser caches when you power on your PC. (Hint: the steps include the use of Ethernet, DHCP, ARP, DNS, TCP, and HTTP protocols.) Explicitly indicate in your steps how you obtain the IP and MAC addresses of a gateway router.
