Digital Technologies / Year 7 and 8 / Knowledge and understanding / Digital systems

Curriculum content descriptions

explain how hardware specifications affect performance and select appropriate hardware for particular tasks and workloads (AC9TDI8K01)

Elaborations
  • explaining how hardware specifications affect what, and how quickly, a digital system can perform tasks, for example how different bandwidth networks affect download speed and lag or how much random access memory (RAM) is needed for multimedia authoring
  • selecting appropriate hardware for particular tasks, for example choosing a powerful graphics card for computer gaming or large external storage for video editing
  • considering how First Nations Australians communities in areas classified as remote often share access to smartphone and internet services, and how the hardware specifications of these devices affect performance, for example where immediate and extended families share and access data through a single smartphone or device
  • explaining how the specifications of components in a system impact the speed with which AI models can be trained; for example, GPUs are more efficient at performing the mathematical calculations necessary for training generative AI than CPUs

Creating a digital start line and finish line with micro:bits: years 7-8

This PDF provides a sequence of activities in which students create algorithms to measure the time taken for a vehicle to travel from a starting line to a finish line. Students connect micro:bits and laser receiver sensors to measure time, then create programs to undertake the timing using visual and general-purpose programming.
