List-I (Algorithm Mode) A. Non-Preemptive B. Preemptive C. SRTF D.

A-1, B-2, C-3, D-4 Explanation: A. Non-Preemptive 1. Running process keeps the CPU until it voluntarily terminates or blocks Non-preemptive scheduling me jab ek process ko CPU allocate ho jata hai, tab tak CPU uske paas rahta hai jab tak woh khud finish (terminate) na ho jaye ya I/O request ke liye block na ho jaye. B. Preemptive 2. OS can interrupt a running process to switch to another Preemptive scheduling me Operating System running process ko execution ke beech me forcibly interrupt karke CPU dusre process ko allocate kar sakta hai. C. SRTF 3. Preemptive version of Shortest Job First scheduling SRTF (Shortest Remaining Time First) Shortest Job First (SJF) scheduling algorithm ka preemptive version hota hai. D. Preemptive Priority 4. Displaces running process if a higher priority job arrives Preemptive Priority sched
