Data representation
This content descriptor sets out learning for Years 9 to 10 Digital Technologies. Use it to plan lessons and assessment with the Australian Curriculum v9.
Elaborations
- • Elaboration using an algorithm to identify patterns in data and represent them in a compressed way, for example repeated pixels in an image with run-length encoding
- • Elaboration exploring the difference between lossy and lossless compression and the consequences of each, for example exploring codecs for audiovisual compression such as MP3, MP4 and WAV formats, considering energy requirements of file sizes
- • Elaboration examining an image and discussing whether the image quality would be compromised if all the blue pixels of the sky in one row were to be replaced by one token and the number of pixels it represents
