Describe the core mechanism of Round Robin (RR) Scheduling. Explain the critical trade-off involved in selecting a very small versus a very large time quantum.
Explain the primary goal of the Multilevel Feedback Queue (MLFQ) scheduler. Detail how it uses multiple queues and changing priorities to fa...
Define Priority Inversion. Explain how the Priority Inheritance Protocol solves this problem and list one real-world critical system where t...
Distinguish between a CPU-Bound Process and an I/O-Bound Process. Explain how a scheduler should prioritize each type to maximize overall sy...
List 5 distinct CPU Scheduling Criteria (e.g., Throughput, Latency) that an OS designer attempts to optimize. Explain which criteria are typ...
Compare First-Come, First-Served (FCFS) and Shortest-Job-First (SJF) scheduling. Provide a numerical example of 3 jobs to show why FCFS ofte...
Define Priority Scheduling and explain the problem of Indefinite Blocking (Starvation) that can arise. Describe the technique of Aging used ...
Define Turnaround Time for a process. Given 3 processes with burst times (P1=10, P2=5, P3=2) all arriving at t=0, calculate the average Turn...
Distinguish between Preemptive and Non-Preemptive scheduling. Name one common scheduling algorithm of each type and the key decision point f...
Define CPU Utilization. Explain why the OS attempts to keep this metric high, and describe a scenario where 100% utilization might indicate ...
Describe the two main priority classes (real-time and variable) used in the Windows scheduler. Explain how the concept of quantum expiration...
Explain the necessity of Load Balancing in multi-core CPU scheduling. Compare the two main techniques: Push Migration and Pull Migration.
Define Response Time and Waiting Time for a process. Explain why Response Time is a more critical metric for interactive, user-facing applic...
