How does it work?

Wondering what the stages of throttle response are. Say I am moving at 5MPH and then floor it. How does the engine/transmission/tubos act? I know the engine revs up and, I think, the trans kicks down and somewhere the turbo kicks in or revs up or something. Just curious and all comments are welcome. I guess what I am looking for is how does the turbo work? Is it spinning all time and then give a boost somewhere during the rev up.
