• A. preemptive scheduling
• B. non preemptive scheduling
• C. shortest job first
• D. first come first served

Answer 1

The correct option is A preemptive scheduling

The strategy of allowing process that are logically runnable to be temporarily suspended is called preemptive scheduling.

Round Robin is the preemptive process scheduling algorithm. Each process is provided a fix time to execute, it is called a quantum. Once a process is executed for a given time period, it is preempted and other process executes for a given time period. Context switching is used to save states of preempted processes.
