🤖 AI STUDY PRIORITY & NUMERICAL MASTERY GUIDE
Highlights the high-weight problem-solving and conceptual slides you should practice with pen and paper: 4 Scheduling Decision Points (Slide 12), 5 Criteria & Optimization (Slides 14–15), FCFS Case 1 & Case 2 (Slides 18–20), SJF All-at-0 vs FCFS 10.25ms (Slide 23), Non-Preemptive SJF vs Preemptive SRTF (Slides 25–26), Priority Gantt 8.2ms (Slides 30–31), Aging 127→0 in 31.75h (Slide 34), and Round-Robin q=4, Max Wait (n-1)q, Context Switch & Turnaround 29 vs 20 (Slides 36–40).
🧮 Interactive CPU Scheduling Simulator & Step-by-Step Math Lab
Select any official numerical example from the lecture (or test custom values) to inspect its Gantt chart, timeline trace, and waiting/turnaround formulas.
⏱️ Slide 34 Interactive Aging Calculator
Lecture Default: Priority 127 (low) to 0 (high), aging by 1 every 15 minutes → 1,905 mins = 31.75 hours (< 32 hours).
🔄 Slides 37 & 39 RR Formula & Context Switch Explorer
Explore how number of processes (n), time quantum (q), and process burst time affect max wait (n-1)q and context switches.
