1. LAN (Local Area Network) is the network that all of your devices are connected to. Some of these devices may be your phone, your computer, or a gaming console.
2. Something that I learned about a home network is that at some point, it is connected to a wire that runs across the bottom of the ocean. I find that completely surreal and cool.
3. One thing that I would tell someone about a home network is all about bandwidth. If you have many devices on one network, it will be slow and laggy.
