What is the main objective of CPU scheduling in multiprogrammed operating systems?
What is the main objective of CPU scheduling in multiprogrammed operating systems?
- To have some process running at all times, to maximize CPU utilization (correct)
- To allocate CPU to only one process at a time for maximum efficiency
- To keep all processes in the waiting state to reduce CPU load
- To minimize CPU utilization for better resource management
In preemptive scheduling, under which circumstances does a process switch from the running state to the ready state?
In preemptive scheduling, under which circumstances does a process switch from the running state to the ready state?
- When a process switches from the running state to the waiting state (correct)
- When a process switches from the waiting state to the ready state
- When a process terminates
- When a process switches from the ready state to the running state
What is the primary criterion for comparing CPU-scheduling algorithms?
What is the primary criterion for comparing CPU-scheduling algorithms?
- Input/output operations: prioritize processes with more I/O operations
- CPU utilization: keep the CPU as busy as possible (correct)

Study Notes
CPU Scheduling Objectives
- The main objective of CPU scheduling in multiprogrammed operating systems is to allocate the CPU time to multiple processes efficiently.
Preemptive Scheduling
- In preemptive scheduling, a process switches from the running state to the ready state when it is interrupted by the operating system or when it requests I/O operations.
Comparing CPU-Scheduling Algorithms
- The primary criterion for comparing CPU-scheduling algorithms is CPU utilization.
Nonpreemptive Scheduling
- In nonpreemptive scheduling, a process releases the CPU when it terminates or requests I/O operations.
Throughput in CPU Scheduling
- Throughput measures the number of processes completed per unit time in terms of CPU scheduling.
