About this paper

CSC 314: Continuous Assessment for CSC314 Operating Systems, Department of Computer Science, Faculty of Science, University of Buea, Instructor Dr NYAMSI, May 2026. Reading and Comprehension: 15 short-answer questions covering OS definition/services/components, multi-processing, privileged instructions, PCB, scheduler, process-management activities, preemptive vs non-preemptive scheduling, resource-usage sequence, CPU scheduling criteria, critical section, IPC and IPC models, and threads. Exercise 1: a 6-process CPU-scheduling problem computing average turnaround/waiting time under FCFS (non-preemptive) and SJF (preemptive), plus a Round-Robin schedule (quantum assumed 10) with Gantt chart, completion/turnaround/waiting times, and a comparative discussion of the three algorithms' performance.
