Investigate how digital systems represent text, image and audio data in binary (ACTDIK024)

Elaborations
  • explaining that characters in text correspond to numbers defined by the character set, for example ‘A’ corresponds to 65 in the ASCII and Unicode character sets
  • recognising that Unicode attempts to represent the written symbols of every language; and using Unicode charts to look up characters from Asian writing systems
  • investigating the different representation of bitmap and vector graphics and its consequences, for example pixelation in magnified bitmap and vector images
  • investigating how colours are represented in images and videos, for example manipulating red, green and blue (RGB) colours in an image editor
  • converting between decimal and 8-bit (1 byte) unsigned binary, covering whole numbers typically used for characters and RGB, for example 65 in decimal is 01000001 in 8-bit binary
  • explaining ways media elements are presented, for example the difference between embedded and linked media elements
General capabilities

Everything is numbers!

In this sequence students learn how the binary number system works, how we can represent text using binary numbers and learn one of the representations of the standard English alphabet used by computers. They look at how the same concepts apply to non-text data and analyse the effectiveness of some binary representation ...
