Operating System Concepts - CPU Scheduling Quiz

What is the main concern regarding the CPU burst distribution?

• Dispatcher module

• CPU–I/O Burst Cycle

• Maximum CPU utilization obtained with multiprogramming

• CPU burst followed by I/O burst

Which scheduling scheme is nonpreemptive?

• Round Robin

• Priority Scheduling

• First-Come, First-Served (FCFS) Scheduling

• Shortest-Job-First (SJF) Scheduling

What can preemptive scheduling result in when data are shared among several processes?

• Dispatcher

• Race Conditions

• CPU Scheduler

• Thread Scheduling

What is the purpose of the Dispatcher module in CPU scheduling?

• All of the above

• Jumping to the proper location in the user program to restart that program

• Switching to user mode

• Switching context

Which scheduling algorithm gives minimum average waiting time for a given set of processes?

• Round Robin (RR)

• Shortest-Job-First (SJF) Scheduling

• Priority Scheduling

• First-Come, First-Served (FCFS) Scheduling

What is the main advantage of using Multicore Processors?

• Increased context switch time

• Lower power consumption

• Higher average turnaround time

• Single-threaded performance

Which type of latency is the time from arrival of interrupt to start of routine that services interrupt?

• Response time

• Interrupt latency

• Dispatch latency

• Event latency

What is the main challenge in Real-Time CPU Scheduling?

• Hard real-time systems

• Soft real-time systems

• Event Latency

• Load Balancing

What is the purpose of Processor Affinity in CPU scheduling?

• To assign memory closes to the CPU the thread is running on

• To keep all CPUs loaded for efficiency

• To switch between various queues

• To specify a set of processors a process may run on

Which scheduling algorithm assigns each process the length of its next CPU burst?

• Shortest-Job-First (SJF) Scheduling

• First-Come, First-Served (FCFS) Scheduling

• Priority Scheduling

• Round Robin (RR)
