QUIZ #1 - FINALS

It has to make sure that whenever the CPU remains idle, the OS at least selects one of the processes available in the ready queue for execution.

• CPU Algorithm

• CPU Scheduling

• CPU Scheduling Algorithm

• All of the Above

What is the difference between preemptive and non-preemptive?

• Non-preemptive keeps the CPU busy while Pre-emptive is assigned with their priorities

• Non-preemptive it keeps the processes continuous while pre-emptive has a different time.

• Non-preemptive it keeps the processes continuous while pre-emptive has a different time.

• Both preemptive and non-preemptive are useful in CPU scheduling.

It is the time required by the process to complete execution. It is also called running time.

• Run time

• Finish time

• Arrival Time

• Burst Time

It is when the process is complete and exits from a system.

• Run time

• Finish time    

• Arrival time

• Burst time

It is a kind of program that has user interaction.

• multi-programming

• User

• Process

• Jobs

It is the reference that is used for both job and user.

• multi-programming    

• User

• Process

• Jobs

It is the amount of time in which the request was submitted until the first response is produced.

• Waiting time

• Response time

• Turnaround time

• Throughput

In this type of algorithm, the process that requests the CPU gets the CPU allocation first.

• First Come First Serve

• Shortest Job First

In this type of algorithm the process having the smallest execution time is chosen for the next execution.

• First Come First Serve

• Shortest Job First

Once the CPU cycle is allocated to a process, the process holds it till it reaches a waiting state or is terminated.

• True

• False
