Total questions: 20
Worksheet time: 10mins
Which of the following best explains a technological system?
A single device that works independently
A set of components that work together to achieve a specific purpose
A system that only works with human input
A machine that requires no energy
Why is an input necessary in a technological system?
It provides the resources needed for the system to function
It ensures the system does not produce outputs
It keeps the system from interacting with the environment
It prevents the system from using energy
Describe the purpose of a process in a technological system.
It interprets inputs and makes decisions to produce outputs
It stores all inputs without using them
It releases energy without control
It removes all outputs from the system
Which of the following is an example of an output in a technological system?
A microprocessor running software
A computer screen displaying information
A battery providing power
A human pressing a button
Explain why feedback is important in a technological system.
It prevents the system from making changes
It helps the system improve its performance by adjusting based on outputs
It blocks any external inputs from affecting the system
It removes outputs before they can be used
Which of the following best describes an open system?
A system that does not interact with its surroundings
A system that exchanges energy and matter with its environment
A system that only receives inputs but does not release outputs
A system that is completely isolated
Why is a thermostat considered a feedback system?
It adjusts the room temperature based on sensor data
It produces heat but does not change settings
It works without any external input
It only releases energy without control
An example of an input in a technological system is:
a) A printed receipt from an ATM
b) A user pressing a button on a remote control
c) A computer displaying an error message
d) A smartphone ringing
Which of the following is an example of an open system?
A closed water heating system
A smartphone that receives calls and sends messages
A battery that stores and releases energy
A sealed cooling system
Explain how an ATM processes a transaction.
It prints receipts without verifying data
It only stores user information without processing it
It verifies the user’s PIN, checks balance, and dispenses money
It provides access without requiring a password
Which of the following is an example of feedback in a technological system?
A conveyor belt moving products
A lightbulb turning on
A smart thermostat adjusting the temperature
A faucet delivering water
Why is a car’s air conditioning system considered a closed system?
It recirculates refrigerant without external exchange
It continuously takes in new air
It releases refrigerant into the environment
It operates without energy input
Describe how a self-service airport kiosk produces outputs.
It only takes user input without displaying results
It prints boarding passes, displays flight info, and provides audio instructions
It operates without electricity
It stores all data without sharing it
Which of the following best explains an ATM as a technological system?
It only accepts cash deposits
It provides outputs such as cash withdrawal and printed receipts
It does not require any processing
It does not provide user interaction
Why is energy considered an input in a technological system?
It helps the system function by providing power
It blocks the system from receiving information
It prevents the system from operating
It removes any processed data
Describe an example of an output in an ATM system.
The card inserted into the machine
The user entering a PIN
The cash dispensed after verification
The electricity powering the machine
Which of the following is an example of information as an input?
A speaker announcing departure times
A user entering a command into a computer
A printed ticket from a vending machine
A smartphone screen lighting up
Explain the purpose of a process in a technological system.
It converts inputs into useful outputs
It blocks the system from interacting with the environment
It only stores energy without using it
It prevents data from being processed
Which of the following technological systems does NOT function as an open system?
A radio broadcasting station
A hydroponic farming system that recirculates water
A ventilation system that exchanges air
A mobile phone sending signals
Why does a smart thermostat adjust itself automatically?
It receives feedback from temperature sensors and changes settings accordingly
It only operates when manually adjusted
It does not measure temperature changes
It continuously releases heat without adjustment
