What is a system?
A set of part of processes which work together to achieve an output or perform a function
What is a close loop system?
A system which incorporates feedback to control and manage the system
What is an open loop system?
A system which is controlled without the benefit of feedback
What is feedback?
Part of a closed loop system which monitors the output and sends a signal back to the input
