Learning Outcomes

  1. Describe the role of hardware/software and explain the fetch-execute cycle at a basic level.
  2. Explain the function of an operating system and compare common operating systems.
  3. Explain how text, images and sound are represented in binary and describe units of data storage.
Assessment

Assessed by coursework (no written examination) — an assignment, case study or presentation set at the start of Semester 2. A formative draft is reviewed with tutor feedback as the unit’s midterm assessment during the teaching weeks, and the final version is submitted in the final exam week at the end of the semester. Graded Pass, Merit or Distinction, with plagiarism-checked submissions (Turnitin) and a signed Learner Declaration Form.
