Problem
You use many networks nearly every day, such as when you check your email, post on social media, use your smartphone, pay at a store, or even drive down the road. Perhaps you've had some experience working with networks, either setting up a network or troubleshooting problems. Did you set up your home network? Have you had to troubleshoot a problem with your employer's network?
Consider the following questions:
1. What did you notice about how devices communicate with each other?
2. What solutions did you find to problems you encountered?
3. What questions do you have now that warrant further research?
