Operating system mcq

1. Which module gives control of the CPU to the process selected by the short-term scheduler?
  •  dispatcher
  •  interrupt
  •  scheduler
  •  none of the above


2. The processes that are residing in main memory and are ready and waiting to execute are kept on a list called :
  •  job queue
  •  ready queue
  •  execution queue
  •  process queue


3. The interval from the time of submission of a process to the time of completion is termed as :
  •  waiting time
  •  turnaround time
  •  response time
  •  throughput


4. Which scheduling algorithm allocates the CPU first to the process that requests the CPU first?
  •  first-come, first-served scheduling
  •  shortest job scheduling
  •  priority scheduling
  •  none of the above


5. In priority scheduling algorithm :
  •  CPU is allocated to the process with highest priority
  •  CPU is allocated to the process with lowest priority
  •  Equal priority processes can not be scheduled
  •  None of the mentioned


6. In priority scheduling algorithm, when a process arrives at the ready queue, its priority is compared with the priority of :
  •  all process
  •  currently running process
  •  parent process
  •  init process


7. Which algorithm is defined in Time quantum?
  •  shortest job scheduling algorithm
  •  round robin scheduling algorithm
  •  priority scheduling algorithm
  •  multilevel queue scheduling algorithm


8. Process are classified into different groups in :
  •  shortest job scheduling algorithm
  •  round robin scheduling algorithm
  •  priority scheduling algorithm
  •  multilevel queue scheduling algorithm


9. In multilevel feedback scheduling algorithm :
  •  a process can move to a different classified ready queue
  •  classification of ready queue is permanent
  •  processes are not classified into groups
  •  none of the mentioned


10. Which one of the following can not be scheduled by the kernel?
  •  kernel level thread
  •  user level thread
  •  process
  •  none of the mentioned
