People say Wi-Fi when they mean the internet. A working signal can still leave a page frozen. Wi-Fi is only the last wireless hop, and its history has a funny reversal in it.
People say Wi-Fi when they mean the internet, which is why a working Wi-Fi signal can still leave you staring at a page that will not load, and a dead router can make you feel like the whole internet broke. They are not the same thing. Wi-Fi is just the last, wireless hop.
Wi-Fi is the wireless link between your devices and your router inside your home. The internet is the whole world outside your front door. Wi-Fi is only the part with no wires.
Let me take you back. Before cable TV, we put antennas on top of the house, or at least on top of the set. Two metal rods poking up in opposite directions, which everybody called rabbit ears. Television arrived through the air, wireless, and you nudged those ears around until the picture stopped snowing.
Then cable came along, and TV went the other way: from wireless to wired. We happily traded the antenna for a cable because it meant a clearer picture and far more channels.
The internet made the exact opposite journey. In the early days every connection was wired. Whatever kind of connection you had, the computer was plugged into something, tethered to the wall. Then Wi-Fi showed up and cut the cord, and suddenly we could carry the internet from room to room, out to the porch, anywhere in the house. No more strings on me.
Wi-Fi did not invent the internet. It just cut the last wire, so you could get up and walk around with it.
This is the key to a lot of “the internet is down” moments. Your Wi-Fi can be strong and perfect, five full bars, while the actual internet coming into the house is dead. The wireless hop to your router works fine; there is just nothing on the other side of the router to fetch. Strong Wi-Fi is not the same as a working connection.
Your router sends out a radio signal that fills your home, the way a lamp fills a room with light. Your phone and laptop pick up that signal and talk to the router without any cable in between. The router, in turn, is connected to the wider internet. Wi-Fi is only that final wireless stretch between your gadgets and the router. Useful to remember the next time everything looks connected but nothing loads.

The cloud isn't in the sky. It's in giant, humming, refrigerated warehouses full of computers, and they're hungry for electricity and water. Here's what a data center is.
New phones are ditching the little SIM card tray. An eSIM is the same thing, built in and programmed over the air, like a hotel updating your key card without a trip to the front desk.
