How Thread Scheduler schedule the task?

Thread scheduler maintains threading states by using primitive and time slicing scheduling. It schedules the tasks by setting priority and time. Only one thread can run at a time in a single process by thread scheduler. When the highest priority is set to a process, the first process at highest priority gets starts before coming into dead or waiting state, after that the next process in the waiting state comes and make it task done and so on. This is how the thread scheduler schedules the task.
