Paper 2 Computational Thinking Thinking ahead Inputs and Outputs

Identify inputs and outputs in a given situation.

Every computer system takes in data, processes it, and produces a result. Inputs are the data or signals entering the system, while outputs are the actions, information, or responses the system gives back. Being able to recognise the difference helps you analyse how real-world and programmed systems work.

Start Activity 1
Toy robot security system from the lesson resource
The robot uses sensors as inputs and actions as outputs.

Activity 1

Robot security system

Sort 7 statements

The robot is left in a dark hallway and must react to light, sound and movement. Decide whether each statement is an input or an output.

Statement bank

Choose a category for each one.

Inputs

0

Sensors or data entering the system.

Outputs

0

Actions or information produced.

Activity 2

Your own programs

Fill 5 rows

Choose at least five different programs you have written. For each one, explain what it does and identify its inputs and outputs.

Activity 3

Payroll system challenge

Classify 6 payroll items

Decide which statements are data going into the payroll system and which are results produced by it. Sort each one into the correct column.
