About this paper

CSC 314: A two-page Continuous Assessment for CSC314 Operating Systems at the University of Buea, Faculty of Science, Department of Computer Science (Dr Nyamsi, Friday 08 May 2026). The source is a handwritten, graded student script; the Student UB Number and Student Name fields are blank on the original, so no student PII is present, and only the printed question text was transcribed (handwritten answers and grader marks were not reproduced as content). Part one is a 15-question reading-and-comprehension section covering operating-system fundamentals (definition, OS services, components, multi-processing, privileged instructions, process control blocks, schedulers, process-management activities, preemptive vs non-preemptive scheduling, resource-utilization sequence, CPU scheduling criteria, critical sections, inter-process communication via shared memory and message passing, and threads). Part two (Exercise 1) is a CPU-scheduling problem with six processes (priority, burst, and arrival times given), requiring independently derived FCFS, preemptive SJF (shortest-remaining-time-first), and Round-Robin (quantum 10) schedules with turnaround-time and waiting-time calculations, plus a comparative performance discussion.
