How a program -something digital- can modify something physically?
In: 3
Imagine a bunch of aqueducts, rivers, trenches, sluices, ravines, troughs, or pipes. All inter-connected with valves and gates and such.
Imagine the water flowing or not flowing through these things. Digital software physically modified circuits by flowing electricity through them. Sometimes there’s too much water and a little stream can overflow and get water everywhere. In a circuit, that would be a trace getting too hot and burning up
The flow of electricity is a real physical property. It’s just energy rather than matter.
Likewise, anything digital exists in real-space in a really real way as a patter of electrical signals with computer memory.
(Some chips like FPGAs can have their physical configuration altered by software. But those aren’t IC chips.)
