Can anybody help me wih these I just don't fully understand this yet thank you!!!

1.) What is the difference between on/off control and continuous PID control?

2.) What happens to a feedback control loop when the set point is changed?

3.) What happens to a feedback loop when a disturbance occurs?

my guesses are for the first the on/off only has two configurations 0% and 100% control while for pid you have 0-100% am i right?

for the second i don't have anything on that and for the third i think the loop will be closed...

please help, we have a preliminary exam tomorrow and i need to do good at this thanks!!!
