Answer 1

Answer:

C. All of the above

NON PREEMPTIVE SCHEDULING 

• In this, once the resources (CPU cycle have been allocated to a process, the process holds it until it completes its burst time or switches to the 'wait'state.

• A process can't be interrupted until it terminates itself or its time is over.

• If a process that has a long burst time is running the CPU, then the process that has less CPU burst time would starve.

• Examples: First Come First Serve and Shortest Job First .
