A preemptive scheduler is a type of scheduling solution used in computer operating systems where the scheduler can interrupt a running process and allocate the CPU to another process based on priority. Advantages of using a preemptive scheduler include an efficient utilization of resources, better prioritization of processes, and interactive response time.  Disadvantages are present such as increased system overhead, less efficient scheduling for short jobs and processes, added complexity, and the possibility of race conditions and other synchronization issues. Preemptive scheduling can be more complex than non-preemptive scheduling. This is because it requires more advanced algorithms and data structures to manage process scheduling.
