Answer 1

Not really a programming question, but ok. Just quoting off my head: WiFi is a technology which allows data to be transferred over radio waves instead of a solid medium, like wires. That is all there is to it.

The thing is, WiFi is usually only between your device and your wireless router. Data still has to be sent through fibre optics (or whatever medium) between your router and the destination server. This is where your internet service providers (ISP) charge you for subscription fees. Without service from ISPs, all you have is a wireless router which broadcasts a WiFi network you can connect to, but can't communicate with the rest of the internet.

Answer 2

Wifi router is a car. and provider is a fuel. No gas no jazz.... Without fuel car is a complicated pieces of metal and plastic. Not a vehicle.
