In this course, Prof. Richard Buckland gives 51 video lectures on Higher Computing. This is the introductory course for computer science at UNSW. This course consists of three strands: programming, systems, and general computer-science literacy. The programming strand is further divided into two parts. For the first half of the course we cover small scale programming, in the second half we look at how to effectively use teams to produce more substantial software. In the systems strand we will look at how computers work. Concentrating on microprocessors, memory, and machine code. In the literacy strand we will look at topics drawn from: computing history, algorithms, WWW programming, ethics and law, cryptography and security, and other topics of general interest. The strands will be covered in an intermingled fashion. The following course, COMP1927 "Data Structures and Algorithms", will be recorded and posted in semester 2 of 2009.
