The selection process is carried out by the ?

• CPU Scheduler

• Non preemptive Scheduling

• Preemptive Scheduling

• Dispatcher

Module gives control of the CPU to the process selected by the CPU scheduler

• Dispatcher

• CPU Scheduler

• Non preemptive Scheduler

• Preemptive Scheduler

The scheduling in which a running process cannot be interrupted by any other process

• Dispatcher

• Preemptive Scheduling

• Non preemptive Scheduling

• CPU Scheduler

Total amount of time a process has been waiting in the ready queue

• Throughput

• Turnaround time

• Response time

• Waiting time

Amount of time to execute a particular process

• Waiting time

• Turnaround time

• Response time

• CPU utilization

Keep the CPU as busy as possible

• Throughput

• CPU Utilization

• CPU Scheduler

• Response time

Time at which the process arrives in the ready queue

• Turnaround time

• Arrival time

• Completion time

• Waiting time

Time required by a process for CPU execution

• Arrival time

• Completion time

• Burst time

• Turn around time

Time at which process completes its execution

• waiting time

• Arrival time

• Burst time

• Completion time

Simplest scheduling algorithm that schedules according to arrival times of processes.

• First Come First Serve

• Shortest Job First

• Round Robin Scheduling

• Priority Based scheduling
