What does this lesson cover?
Many students think a network is only for getting on the Internet, or that a message goes straight from their computer to a website. This lesson shows the devices a message passes through, like a switch, a router and the Internet service provider. Students also learn that a network's type depends on the area it covers, not on how many devices it has.
Follow the Message
Students trace four messages through an auto repair shop's network and decide if each one needs the Internet.
