A) Preemptive scheduling does not allow the operating system to interrupt a process, while non-preemptive scheduling allows frequent interruptions. B) Preemptive scheduling allows the operating system to interrupt a process in the middle of its execution, while non-preemptive scheduling does not. C) Preemptive scheduling is used for single-core processors, while non-preemptive scheduling is used for multi-core processors.
