I think Hans covered most of this, however, I wanted to point out that a
component's job is to service one or multiple CSIs.  CSI (Component
Service Instantiation) is a single instance of a component service.  If
you wanted, you could also have a component that only services one CSI
with four copies of your component running.  You would have to change
the configuration for this to occur.
