9IPT: Displaying Hardware (2)

posted Aug 1, 2011, 1:53 PM by Eddie Woo
It's fitting that under the displaying process, we would be able to look at so many cool videos. That's because the hardware used for displaying is so intriguing and clever in its execution - we take so much for granted when we simply look at a computer screen or print out a piece of paper. Amazing feats of science and technology are taking place behind what we think of as very mundane processes!

Please complete the following tasks:
  1. Describe the operation of an inkjet printer, and hence explain some of the disadvantages of this printing method.
  2. Compare and contrast the operation of a thermal inkjet printer with a piezoelectric inkjet printer.
  3. Describe the operation of an laser printer, and hence explain some of the disadvantages of this printing method.
  4. Describe the method used by a 3D printer to create figures with height, width and depth.
  5. Outline the way in which a speaker creates different sounds.
