What is Wi-Fi?
You tap your phone and a video starts playing. You're sitting on the couch, nowhere near a wire, yet somehow the internet found you. How? The answer is invisible, fills your whole house right now, and has a name that sounds like a friendly dog: Wi-Fi.
Wi-Fi is just radio waves — the same kind that carry music to car radios or voices to walkie-talkies. Your house is full of them, bouncing off walls, curving around corners, carrying tiny packets of information at the speed of light. They're always there, you just can't see or feel them.
