Unit 7: Digital Systems

Unit 7: Digital Systems

Teachers: This Unit builds on learning covered in Unit 1. We recommend a quick refresh.

Take a closer look at the computer you are using. It has many parts (peripherals) that are connected to it. Early computers could only process text (input) via a keyboard. Today there are lots of other devices that we can easily connect to any digital device. Each peripheral has an input or an output function. Look at the image above and decide which peripheral is input or output in function.

In this Unit we will focus on the most popular of input peripherals - the digital camera.

Ask your teacher to arrange for the class to explore some digital cameras. Can you turn it on and off?  Take a photo? Delete a photo? How does it connect to a computer - using a cable or SD card maybe? Can you download / transfer a photo to your computer?

Watch the video about input and output peripherals (top video). How many peripheral devices have you used?

  1. Using a digital camera take 5 photos
  2. Download and save those photos to your computer or as instructed by your teacher.
  3. Watch the DigitalNinja video (right) about how to use www.fotor.com online image/photo editor.
  4. Edit and re save each photo.
  5. Make a collage or card with the photos
  6. Save your finished collage or card.
  7. Upload it to a location (ask your teacher) so others in your class can see your brilliance.
Discuss other popular peripherals that people use.

Unit 7 Fotor

Digital words are a part of our everyday life. After watching the videos above, try to complete a word search below. 

Fill in the blanks


  • Identify and explore digital systems (hardware and software components) for a purpose.
  • Digital Systems / Foundation to Level 3 – 4  Elaborations

    1. Playing with and using different digital systems for transferring and capturing data, for example using a tablet to take a photograph of a grandparent and recording an interview with them about life in the past
    2. Exploring and using digital systems for downloading and storing information, for example knowing how to download images from a website and insert them into a document
    3. Exploring and identifying hardware and software components of digital systems when creating ideas and information, for example experimenting with different ways of providing instructions to games software using a mouse, touch pad, touch screen, keyboard, stylus
    4. Recognising and using hardware and software components of digital systems and experimenting with their functions, for example playing with interactive toys and robotic devices to determine which ones can work with other devices
    5. Recognising that a digital system follows instructions or commands, for example instructing robotic toys to perform a function such as a dance movement
    6. Constructing a model of a real or imaginary digital systems device for use in role-play scenarios and explaining the features of the device to an adult
