The lecture's powerpoint slides should be the first port of call for the student. Each slide set will contain reference to the literature used by the instructor to prepare the lecture.

In addition, there are two textbooks that the students may wish to consult. This is Sawyer, Stacey and Brian K. Williams. "Using Information Technology: A Practical Guide to Computers and Communication", McGraw Hill 2003. The other is White, Ron "How computers work", referred to as above. Both books contain many mistakes.


Every lecture—except the first two—will contain a quiz of about ten minutes duration. The average of the grades of the quizzes makes for 50% of the course.

The remainder is composed from a essay. It should be brief, i.e. less than five pages, and must be handed in on the day of the last class.
