How do mobile apps access the internet?

I was just wondering how mobile apps that require internet connect like Facebook or mobile banking apps get their information? What kind of requests does the app make to a server?

For example for mobile banking, when you log in it displays your checking/savings balance. How does it retrieve that information?

Thanks!

    Internet connections are pretty much the same regardless of whether they are wired or wireless. So your mobile app either connects to the internet via WI-FI or the mobile cellular data network. So understanding wi-fi is pretty easy. A radio link provides the connection to the wi-fi router. From there, a wire connects to the larger internet. If you are out of a WI-Fi hotspot, the connection is via the cellular radio to a nearby cell tower. Then from there to the internet. Conceptually it's the same as wi-fi. just over a longer distance.

    Thanks to the ISO 7 layer network model, the app is not aware of the differences in the connection. It all works the same as far as the app is concerned.
