Combine it with memory parts, which you can think of as light switches that remember the "on" and "off" position you set them to. Now you have a circuit that can be told how to flip the light switches and pass/process digital data from one side to another.
With enough of these you can make a simple recursive circuit that can be told how numbers are defined, and add/subtract/multiply. With even more you can define words. Combine it, alot of times, and you can make a complex enough circuit that can stream egirls to your phone.
It all started with mechanical machines hundreds of years ago.
Computer chips are simply those machines turned into electrical.
Basically.
