  1. Describe, step by step, what happens when I type www.example.com into my browser and try to go to the page?
  • ANSWER: The browser will ask the OS about "example". The OS will not know and so it will ask the Resolving Name Server which may know "example" if it's stored in the computer's memory. If it doesn't, it will ask the Root Name Server which will give it a direction to retrieve information needed from the TLD (top level domain) servers. The TLD will then direct the RNS (resolving name servers) to the ANS (authoratative name servers). The ANS will then supply the corresponding IP address for www.example.com. The RNS takes this info and stores it in it's cache and then heads back to the OS. OS will then give back to browser which will then take you to the right location.
