Technological Systems
What are the four main components of a technological system?
Input, process, output, and feedback.
What is the input in a simple flashlight system?
Batteries, switch, or electrical energy.
What type of system uses feedback to adjust its output?
Closed-loop system.
True or False: A fan with only an on/off switch is an open-loop system.
True
the action or series of steps the system takes to create an output
The Process
Name a real-world example of a technological system and identify its input and output.
EXAMPLE: A washing machine; input: clothes and detergent, output: clean clothes.
What is the output in a toaster?
Toasted Bread
A thermostat-controlled heater increases temperature when it gets too cold. Is this an example of feedback?
Yes, because the thermostat uses feedback to maintain a set temperature.
What is the main difference between an open-loop system and a closed-loop system?
Closed-loop systems use feedback to adjust their operation, while open-loop systems do not.
A group of parts working together to perform a specific function.
Technological System
Which component of a technological system transforms the input into an output?
The Process
What is the input in a traffic light system?
Sensor data or a timer.
Name a system where feedback plays a critical role in maintaining safety.
EXAMPLE: An elevator system, where sensors provide feedback to ensure proper floor alignment.
Is a microwave that stops cooking when the set time expires an open-loop or closed-loop system?
Open-loop system
a group of systems that communicate with each other
A Network
True or False: All technological systems require feedback to function.
False
What happens when the output of a system does not match its intended purpose?
The system may fail or produce unintended results.
Why is feedback important in a closed-loop system?
It helps the system stay on track by making adjustments.
Explain why a refrigerator is a closed-loop system
It uses sensors to detect the internal temperature and adjusts cooling to maintain a set level.

Protocol
How would you describe the role of feedback in a technological system?
Feedback monitors and adjusts the system to ensure it meets desired outcomes.
How do inputs and outputs work together in a vending machine?
The input (money and selection) triggers the output (dispensing the product).
What does feedback do in a cruise control system?
It keeps the car at a steady speed.
Provide a real-world example of an open-loop system and explain why it is classified as such.
EXAMPLE: A sprinkler timer; it operates based on a set time and does not adjust based on weather conditions.
