The user wants a JSON summary of the provided video lecture about "Highest response ratio next (HRRN)". **1. Analyze the Video Content:** * **Topic:** Operating Systems - CPU Scheduling - HRRN algorithm. * **Visuals:** A slide with bullet points explaining HRRN, its formula, and its benefits. A presenter in the bottom right corner. Handwritten notes appear on the slide later in the video. * **Key Concepts:** * Non-preemptive discipline. * Similar to SJN (Shortest Job Next). * Priority depends on estimated run time and waiting time. * Prevents starvation (indefinite waiting). * Formula: Response Ratio = (W + S) / S. * W = Waiting time, S = Burst time. * Conclusion: Balances short burst time priority with waiting time care. * **Worked Example (Handwritten):** * Processes: P1, P2, P3. * Burst times (S): P1=10, P2=100, P3=1000. * Initial state: Time 0. * At Time 0: *

Ratio = (0+10)/10 = 1. * P2: W=0, S=100. Ratio = (0+100)/100 = 1. * P3: W=0, S=1000. Ratio = (0+1000)/1000 = 1. * Wait, the presenter writes "1" for all initially. Then he seems to be calculating for a specific scenario or just explaining the formula. * Actually, looking closely at the handwritten notes: * He lists P1 (10), P2 (100), P3 (1000). * He calculates ratios. * He writes "1" for P1, "1" for P2, "1" for P3 initially. * Then he seems to be calculating for a later time or just showing the formula application. * Wait, let's look at the later frames. *
