SLR 4 Quiz 4 Operating System Scheduling Algorithms

What is the purpose of a scheduler in multitasking operating systems?

• To allocate memory to different processes

• To handle input/output operations

• To manage which processes to execute next and the length of time that process can execute for

• To manage the user interface of the operating system

Which scheduling algorithm executes processes strictly in the order they arrive?

• Shortest Job First

• Round Robin

• First Come First Serve

• Shortest Remaining Time

In the shortest job first scheduling algorithm, how are processes queued up based on their execution time?

• In the order of arrival time

• In the order of longest to shortest execution time

• Randomly

• In the order of shortest to longest execution time

What is the purpose of a time slice in the round robin scheduling algorithm?

• To allocate memory to processes

• To determine the priority of processes

• To limit the amount of time a process can execute before being suspended

• To suspend processes that take too long to execute

Which scheduling algorithm is preemptive and can suspend a process if a higher priority process joins the queue?

• First Come First Serve

• Shortest Remaining Time

• Shortest Job First

• Round Robin
