๐ Topic Summary
In this unplugged activity, we'll simulate how messages are sent across a network. Instead of computers, we'll use people to represent devices, and physical objects (like paper or balls) to represent data packets. The goal is to understand the basic principles of message sending, including addressing, routing, and error detection, all without needing any actual computers. This hands-on approach makes complex concepts easier to grasp!
Imagine you want to send a secret message to your friend across the playground. Instead of just shouting it out, you break it down into smaller pieces, add a destination address to each piece, and then pass it along a chain of friends. Each friend along the way looks at the address and knows who to pass it to next. That's essentially what we're doing in this activity!

๐ค Part C: Critical Thinking
Imagine the "routers" in our game suddenly stopped remembering where to send the messages. What problems would this cause, and how could you solve them using strategies from the game?
