📝 Sample Questions

Q1. What is the fundamental principle of the Shortest-Job-First (SJF) scheduling algorithm?

🔹 A. The process with the longest CPU burst runs first
🔹 B. The process with the smallest next CPU burst is assigned the CPU
🔹 C. Processes are scheduled in round-robin order
🔹 D. The process with the highest priority runs first

💡 Difficulty: easy | ✅ Correct: B

Q2. Why is SJF used frequently in long-term scheduling but not in short-term scheduling?

🔹 A. It is too complex for long-term
🔹 B. Long-term scheduling can use user-specified time limits
🔹 C. Short-term scheduling doesn't need SJF
🔹 D. Long-term scheduling is less important

💡 Difficulty: medium | ✅ Correct: B

Q3. In preemptive SJF, what happens when a new process arrives with a CPU burst shorter than the remaining time of the currently running process?

🔹 A. The new process waits
🔹 B. The current process continues
🔹 C. The current process is preempted and the new process runs
🔹 D. Both processes share the CPU

💡 Difficulty: hard | ✅ Correct: C
