- The server sends data back to your laptop
Key Points:
- Each device = Node
- Nodes communicate using IP addresses
- Nodes are connected via LAN, WAN, or the Internet

A WWAN is a type of network that provides wireless internet access over a very large area, such as cities, countries, or even worldwide.
Examples of WWAN:
-
Mobile internet on your phone
-
Internet using a SIM card in a laptop
-
