Fascinating Fact:

Feedback is when output is used to adjust the process, like a thermostat changing heating based on temperature readings.

In KS3 ICT, feedback helps a process correct itself while it is running. Many systems take sensor readings or user responses, compare them to a target, and then change what they do next, so the output stays accurate and consistent.

Key Terms

Feedback: Using the output of a system to change what happens next in the process.
Control system: A system that manages a device by monitoring data and making adjustments.
Sensor: A device that measures a physical value, such as temperature, light, or movement, and converts it into data.

Frequently Asked Questions (Click to see answers)

What is feedback in ICT KS3?

In KS3 ICT, feedback is when a system uses its output, or new readings, to change the next step, helping it stay close to a target result.

What is an example of a feedback loop in computing?

A common example is a thermostat: it reads the temperature, compares it to the set level, and turns heating on or off to keep the room near the target.

How do sensors help ICT control systems?

Sensors provide live data, such as temperature or light level, so a control system can decide whether to increase, reduce, or stop an action to improve the output.
