🔹 Radio waves (blue circles) carry information through the air — like invisible messengers traveling at light speed!
🔹 Files, photos, or videos are broken into tiny data packets (red-bordered boxes). Each packet flies from your device to the router, then to the destination.
🔹 The receiving device sends back a tiny ACK (acknowledgment) packet to say "got it!" — that's how WiFi makes sure nothing gets lost.
💡 Pro tip: Click on any device or packet to see detailed information!
