Operating Systems (Assignment 03 - CPU Scheduling)

Which module gives control of the CPU to the process selected by the short-term scheduler?

• Interrupt

• Scheduler

• Dispatcher

• None of the above

The processes that are residing in main memory and are ready and waiting to execute are kept on a list called

• List called

• Job queue

• Process queue

• Executed queue

The interval from the time of submission of a process to the time of completion is known as

• Throughput

• Waiting time

• Response time

• Turnaround time

Which scheduling algorithm allocates the CPU first to the process that requests the CPU

first?

• Priorities scheduling

• Shortest job scheduling

• First come, first-served scheduling

• None of the above

In prority scheduling algorithm

• Equal priority processes cannot be scheduled

• CPU is allocated to the process with the lowest priority

• CPU is allocated to the process with the highest priority

• None of the above

In priority scheduling algorithm, when a process arrives at the ready queue, its priority is compared with the priority of

• All process

• Init process

• Parent process

• Currently running process

Times quantum is defined in

• Priority scheduling algorithm

• Shortest job scheduling algorithm

• Round robin scheduling algorithm

• Multilevel queue scheduling algorithm

Processes are classified into different groups in

• Priority scheduling algorithm

• Round robin scheduling algorithm

• Multilevel queue scheduling algorithm

In multilevel feedback scheduling algorithm

• Processes are not classified into groups

• Classification of ready queue is permanent

• A process can move to a different classified ready queue

• None of the above

Which one of the following cannot be scheduled by the kernel?

• Process
