Questions and Answers

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?

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?

Input/output operations: prioritize processes with more I/O operations

CPU utilization: keep the CPU as busy as possible (correct)

Memory utilization: maximize memory usage for efficient processing

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.
