My internet comes into my house through a phone cable, because I have Verizon FiOS. It then goes through a Modem, and next through a wireless router. Our FiOS plan costs $85/month, which means it costs about $1,020/year. My household has a lot of devices that use our internet connection, including phones and a TV. Altogether, these devices are 2 Mac desktop computers, 3 Mac laptops, 1 TV, 3 house phones, and 2 cell phones. When we were learning about networks, my "OMG moment" was learning how different everyone's networks are, and how they don't even go into people's houses the same way. I had never really thought about networks as things that could be unique to each household. What I would tell people they need to know about having a home network would be that you should know every part that your connection goes through before it reaches all of your devices. That way, if something goes wrong, they will know to check every part for the problem.
