It's from control theory. In an open loop control system I just send the
system messages to tell it how to behave, whereas in a closed loop system
I get messages back so I can check that it's doing what I want. Think of
the difference between a simple mixer tap and a thermostatic mixer.
Open loop:

Closed loop:
