Is there a system hierarchy? How does everything work together?
In: Technology
As u/Luckbot pointed, your computer decide who gets to work when for most things.
So I’ll expand more on how they talk together when they need to. The most basic solution is usually to send a call to the other. Program A will reach a point where it need an information from program B, so it’ll send a message to program B. Program B will receive the message and send and answer to program A.
Now, while it sound simple, there are a few hurdles to go through. Programs rarely multitask and they certainly don’t do it by themselves. So for a program to listen for call, you need to code an ear. That ear need to be able to wait for hearing something, capture the words, translate them into something usable then know what to do with that information. Which can be hours of frustration for coder. Any software that does not have an ear, or isn’t using it cannot interact with others.
