Unit Outline

1 Aims

In this unit, I want to be more specific and look at the way computers represent and handle data. The unit aims to:

  • broaden the definition of a computer and explain the concept of crossing the boundary between the computer's world and our own (Section 2);
  • explain the digital nature of the computer's world and contrast it with our analogue world of sense and motion (Section 3);
  • describe in detail how to transform features of our world into computer representation (Section 4);
  • look at ways in which digital information in the computer can be displayed for our eyes and ears (Section 5);
  • consider the amazing implications of being able to use the computer to manipulate and transform digital representations of our world (Section 6).
