What does this lesson cover?
Students use Wi-Fi, Bluetooth and video calls every day, but many think Wi-Fi and the Internet are the same thing. This lesson sorts out each kind of connection and shows that a video call travels over networks on its way, often through a server. Students also learn that a phone can get online through the cell network with no Wi-Fi at all.
Follow the Call
Students follow four calls and meetings at Spruce Street Architects and write what each one sends and the path it travels.
