Displaying Multiiple Windows

I am trying to research how the Windows OS handles the displaying of several
windows on a common desktop. For example, when I have multiple windows open,
there is only one window that can be "up front" - the one that actually
receives the input from my keyboard. When I choose another window, using my
mouse or switching between active windows using the ALT+TAB & ALT+SHFT+TAB
key sequence, how does the OS segregate the various boundaries between all
the windows it displays? Is there a set of rules, or heirarchy, that easily
defines this process? I'm not a programmer - just someone curious how this
really works.

And if I gave you an answer, would you understand it ??

It all depends on how well you explain it... and I am sure I can get someone
to translate it for me... give me a chance - I'm just trying to better
understand this so that I can apply this capability to another application.
