📚 Topic Summary
Imagine the internet as a giant postal service! Internet routing is like figuring out the best way to send a letter from your house to your friend's house across the country. Instead of houses, we have computers and servers. Instead of streets, we have network connections. Routers are like post office workers, reading the address (IP address) on each packet (letter) and sending it along the best path to its destination. This unplugged activity uses this analogy to help you understand how data travels across the internet.

Answer: Packets, Routers, Destination, IP Address, Route
🤔 Part C: Critical Thinking
Imagine a scenario where one of the main "post offices" (routers) on the internet goes down. What happens to the data being sent through that router, and how does the internet adjust to keep things running smoothly?
