Input–Process–Output: Computer Control Systems

Question 1

What is the role of an input device in a computer control system?

Answer 1

To collect data from the environment and send it to the processor for action.

Question 2

Name three examples of input devices in a computer control system.

Answer 2

Temperature sensor, light sensor, push button switch.

Question 3

What is the function of the process in a computer control system?

Answer 3

It receives data from inputs, makes decisions based on programmed instructions, and sends signals to the outputs.

Question 4

Give an example of a process in a computer-controlled application.

Answer 4

A microcontroller turning on a fan when a temperature sensor detects high heat.

Question 5

What is the purpose of output devices in a computer control system?

Answer 5

To perform actions in response to signals from the processor.

Question 6

Name three examples of output devices in a computer control system.

Answer 6

Motor, LED, buzzer.

Question 7

Describe the Input–Process–Output model.

Answer 7

Inputs detect changes, the processor makes decisions, and outputs perform actions.

Question 8

Give an example of a computer control system used at home.

Answer 8

A central heating system that turns on the boiler when the room temperature drops below a set point.

Question 9

Give an example of a computer control system in transport.

Answer 9

Automatic train doors that open when a sensor detects the train is at a station.

Question 10

Give an example of a computer control system in manufacturing.

Answer 10

A conveyor belt system that stops when a photoelectric sensor detects an item out of place.
