Data representation
This content descriptor sets out learning for Years 7 to 8 Digital Technologies. Use it to plan lessons and assessment with the Australian Curriculum v9.
Elaborations
- • Elaboration explaining how whole numbers can be represented in binary, for example counting in binary from 0 to 31, and recognising that one byte = 8 bits, which can represent from 0 to 255
- • Elaboration explaining how digital systems represent data in binary, for example by converting a character to its Unicode value, then converting that value into binary
- • Elaboration explaining how circuits can perform binary operations represented as on/off states, for example showing how circuits with 2 switches can represent AND or OR gates
