Process - Part-II Quiz

Which of the following scheduling criteria should be minimized?

• CPU utilization

• Throughput

• Turnaround time

• Both a and b

What is a major disadvantage of FCFS scheduling?

• It is complex to understand.

• It can lead to starvation.

• It suffers from the convoy effect.

• It is not easy to implement.

What is the preemptive version of the Shortest-Job-First (SJF) scheduling algorithm called?

• First-Come, First-Served (FCFS)

• Round Robin (RR)

• Shortest Remaining Time First (SRTF)

• Priority Scheduling

What is a key advantage of the Shortest Remaining Time First (SRTF) algorithm?

• It prevents starvation.

• It is simple and easy to understand.

• It guarantees the minimum average waiting time.

• It is easy to implement practically.

A disadvantage of Shortest-Job-First (SJF) scheduling is that it can't be implemented practically because:

• It is a preemptive algorithm.

• The burst time of processes cannot be known in advance.

• It is a non-preemptive algorithm.

• It leads to starvation for processes with smaller burst times.

In priority scheduling, what is the solution to the problem of indefinite blocking or starvation for low-priority processes?

• Convoy effect

• Aging

• Time quantum

• Context switching

What happens to Round Robin (RR) scheduling as the time quantum increases?

• It tends to become FCFS scheduling.

• The number of context switches increases.

• The response time decreases.

• The chances of starvation decrease.

Which of the following is an advantage of Round Robin (RR) scheduling?

• It leads to starvation for processes with larger burst times.

• Its performance is independent of the time quantum.

• Priorities can be set for the processes.

• It gives the best performance in terms of average response time.

In a multiprocessor system, what is the role of the 'master' processor in Asymmetric Multiprocessing (AMP)?

• It executes user programs and specialized tasks.

• It runs tasks independently as a peer to other processors.

• It manages the operating system, handles I/O operations, and allocates tasks to other processors.

• It specifies that a process should not migrate to other processors.

What is the type of processor affinity where an operating system attempts to keep a process on the same processor but does not guarantee it?

• Hard affinity

• Soft affinity

• Symmetric affinity

• Asymmetric affinity
