📚 Topic Summary
This unplugged activity simulates how a computer worm propagates across a network. Instead of computers, we'll use people to represent nodes on the network. One person starts with the "worm" (a piece of information), and they "infect" others by sharing it. As more people become infected, you'll see how quickly a worm can spread and the importance of network security. This activity provides a tangible understanding of network vulnerabilities and the exponential growth of malware propagation.

🤔 Part C: Critical Thinking
How could this activity be modified to simulate how firewalls or antivirus software might slow down the spread of a computer worm?
