Which of the following operating systems uses the non-preemptive type of…

The correct answer is Microsoft Windows 3.1 because it utilized cooperative, non-preemptive scheduling. In this model, a running process must voluntarily yield control of the CPU to allow other processes to execute. If a program failed to yield, it could monopolize system resources indefinitely.\nIn contrast, modern operating systems like Unix and Linux employ preemptive scheduling. This allows the kernel to forcibly interrupt a running process after a specific time slice, ensuring fair resource allocation and system stability. Similarly, Microsoft Windows NT introduced preemptive multitasking, distinguishing it from the earlier non-preemptive architecture of Windows 3.1.",
