1. Imagine one of your devices at home (say, your mobile phone) is communicating through your ISPs network to an Application Server in the network. The mobile phone communicates as follows:
   1. Uses Wi-Fi to communicate with your home Wi-Fi Access Point (set up as a Router);
   2. Via the Home Router, through the ISPs network to an Application Server;
   3. Within the ISP network, data traverses another Router (the ISPs Router) and a Layer 2 Switch, on the way to the Application Server.

1. Draw a topology diagram, showing all the connected components, end-to-end.
2. Draw the end-end protocol stack diagram, showing the protocol layers traversed at each node, including the end hosts (the mobile phone and Application Server).
