Topic notes
CPU and I/O scheduling in GATE CS is predominantly an algorithmic and numerical topic focusing on precise Gantt chart simulation, turnaround/waiting time computation, and comparative metric evaluation. While Preemptive Shortest Remaining Time First (SRTF) and Round Robin (RR) form the core of numerical problems, questions also assess real-time scheduling (Rate Monotonic), multi-processor scheduling, disk I/O head movement algorithms (SCAN, SSTF, C-LOOK), and theoretical properties like starvation and preemption hardware requirements.
