Examine how whole numbers are used to represent all data in digital systems (ACTDIK015)

Elaborations
  • recognising that digital systems represent all types of data using number codes that ultimately are patterns of 1s and 0s (called binary digits, which is why they are called digital systems)
  • explaining that binary represents numbers using 1s and 0s and these represent the on and off electrical states respectively in hardware and robotics
  • recognising that the numbers 0, 1, 2 and 3 could be represented by the patterns of two binary digits of 00, 01, 10 and 11
  • representing whole numbers in binary, for example counting in binary from zero to 15, or writing a friend’s age in binary
  • exploring how division by two can be used as a technique to determine the binary representation of any whole number by collecting remainder terms
  • representing the state of an object in a game as active or inactive using the respective binary values of 1 or 0
General capabilities
  • Numeracy Numeracy
  • Critical and creative thinking Critical and creative thinking
  • ICT capability Information and Communication Technology (ICT) capability
