Things to think about

  • Can you simply explain the structure of the internet to someone else?
  • How do you sense the structure of the internet? Is it a physical reality? Is it a virtual reality? Is it everywhere, for everyone?
  • Is there a difference in your mind between the internet and the world wide web? If yes, explain. If no, what is the difference.
