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