I hope you are all starting to see how a process that may appear simple - such as the first one, collecting - is in fact filled with complex ideas and intricate details. Some of this stuff is quite tricky; the first time I read about the Bayer filter, my head was spinning for hours!

So far under the heading of 'collecting', we have looked at the diverse range of devices used for collecting, studied the technical details of how some of those devices actually go about collecting data, and investigated one scenario (related to our state's traffic infrastructure) that revealed the complexity of the collecting process and how it takes place in the real world.

Now, we move on from our focus on hardware to look at the software side of collecting. In a new classwork post, answer the following questions:
  1. Define the term "device driver".
  2. Outline why device drivers are necessary.
  3. Describe the role of the operating system in the collecting process, during the normal usage of an application.
  4. Propose (i) a problem that could take place because of inappropriate drivers and (ii) an advantage of updating drivers.
  5. Compare application software with the other kinds of software in a personal computer.
  6. Define the following terms: (i) data integrity, (ii) data validation and (iii) data verification.
  7. Outline the key design factors that influence the efficiency and accuracy of user interfaces that are responsible for data entry.
