Learn the idea
An input gives information to a computing device. A key press, touch, mouse movement or microphone sound can be an input. An output is information the device sends out, such as a picture or sound. One device may both receive and send information, so name the action rather than the whole object.
Follow the information arrow: into the device is input, out to the person is output. A touchscreen can receive a touch and show an image; the action determines the role.
Use this supplied case: A child presses a keyboard key; the computer receives a letter. Name the action. Use the details in this example. An adult may read the words aloud. Point, draw or say your answer.
- Follow the worked example one step at a time. Say or draw what happens.
- Follow the information arrow: into the device is input, out to the person is output.
- Say which detail makes the example answer fit. Pick another answer and say why it does not fit.
- Try the question and practice questions. Read the rule again if your answer does not match the explanation.
