Where does the internet come from / how does it work?

I was wondering --


Where does the internet come from? Like the signals, the fast web, the ability to send hole pictures and messages to other places around the world. How does that even work???





Who invented it anyway??





Just wondering and thoughts...thanks!Where does the internet come from / how does it work?
lots of tubes and trucks move fast to keep it all running smoothly.


occasionally a truck will crash and that's why it gets slow sometimes
