Input devices capture data and convert it into electrical signals that can be understood by computers. There are two types of input devices: manual devices like keyboards and mice that require human control, and automatic devices like sensors and webcams that input data without human intervention once set up. The document provides instructions for students to create a presentation and word cloud identifying different examples of manual and automatic input devices.

1. Input devices

3. • To understand the hardware components that
make up networked computer systems.
• To be able to explain how they interact, and how
they affect cost and performance.

4. Watch this clip - think about inputs and outputs.

5. • An input device captures data and sends it to a
computer system.
• Input devices convert physical movement, such as
key pressing, or environmental data, such as
temperature, sound or light into electrical signals.
• There are two types of input device: manual and
automatic

6. • A manual input device requires a human hand to
control it…

7. • An automatic input device inputs data without
the need for human intervention (once the
device has been set up), e.g. MICR, OMR,
barcode reader, webcam, microphone, sensor.

8. • Create a PowerPoint presentation, with separate
slides for different manual and automatic input
devices Explain how the device is used.

9. • Open www.wordle.net Try to include as many
different manual and automatic input devices as
you can in your word cloud.

10. In pairs you have 2 minutes to share one thing
you have learnt in today’s lesson and how it will
help you.
That’s 1 minute each to talk about what you
have learnt in todays lesson.
