What is a characteristic of a closed-loop system?
It operates without feedback
It uses feedback to adjust its output
It requires constant manual input
It never stops once started
Which is a correct example of a closed-loop system?
Traffic light timer
Blender
Thermostat
Alarm clock
What is a primary difference between an open-loop and closed-loop system?
Open-loop systems are faster than closed-loop systems
Closed-loop systems have feedback while open-loop systems do not
Open-loop systems require less energy
Closed-loop systems never fail
Why might a cruise control system be considered a closed-loop system?
It only turns on and off
It uses feedback to adjust the car's speed
It requires manual speed adjustment
It cannot change speed automatically
How does feedback improve the performance of a technological system?
By ignoring changes in the environment
By allowing the system to adjust its output based on results
By making the system run faster
By turning the system off automatically
Which of the following best explains why a washing machine can be a closed-loop system?
It spins clothes at a constant speed
It uses sensors to adjust water levels and cycles
It only washes for a set time
It requires manual operation for each step
In a closed-loop system, what role does the sensor play?
It provides feedback to the system
It starts the system
It supplies power to the system
It stops the system when finished
What is the main advantage of a closed-loop system over an open-loop system?
It is less expensive
It can automatically adjust to changes in the environment
It requires more manual input
It is always faster
If a system automatically adjusts its operation based on the results it produces, what type of system is it?
Open-loop
Closed-loop
Manual
Timed
Which of these is NOT an example of a closed-loop system?
Cruise control in a car
Automatic braking system
A manually controlled lamp
Automated irrigation system
A feedback signal in a technological system helps to:
Provide power to the system
Increase the output speed
Measure performance and adjust input
Stop the system after a set time

Open-loop system
Feedback system
Digital system
Which of the following statements best describes how open-loop systems adjust their performance?
They use feedback to adjust their performance.
They operate without any input.
They use sensors to monitor output.
They do not use feedback to adjust their performance.
An automatic braking system in a car is an example of which type of system?
