Which CPU scheduling algorithm allocates CPU time to processes in fixed units called time slices or quanta?
Show answer & explanation
Answer: A. Round Robin
Round Robin CPU scheduling allocates fixed time intervals (time quanta) cyclically among runnable processes.
Step-by-step Derivation:
Step 1: In preemptive multitasking, Round Robin allocates each process a fixed slice of CPU time.
Step 2: Once the time slice expires, the process is preempted to the back of the ready queue.
