📚 Topic Summary
Imagine the internet as a postal service, and data as letters. Packet sniffing is like observing those letters as they move from sender to receiver. Each 'letter' (packet) contains information such as the sender's address, receiver's address, and the actual message. In this unplugged activity, we'll simulate how someone can 'sniff' these packets to understand the information being transmitted, without actually reading the content of the letters.
