• Sensor, Computer, Actuator

• Input, Process, Output

• Source, Encoder, Transmitter

What is the difference between the input and the output?

• They are the same

• Worst result vs Best result

• Desired result vs Possible result

• Desired result vs Actual result

What are inputs?

• The Desired Result

• Resources such as time, capital, workers, tools, materials, etc

• Both the desired result AND resources

What is an open-loop system?

• Very complex system, self regulating, self repairing

• Very simple system, once started will continue without any change or alteration

• Regular system, able to make slight adjustments

• Semi complex system with some regulator pieces in place

What is a closed loop system?

• A system that loops activities repeatedly until it runs out of energy

• A system that is closed from making adjustments and continues as designed no matter what

• A system complete with a feedback loop capable of making alterations to optimize itself

• A system that can be set to loop a certain amount of times to optimize production.
