Operating Systems MCQs Set-10

1. Bringing a page into memory only when it is needed,this mechanism is called
  • Deadlock
  • Page Fault
  • Dormant Paging
  • Demand Paging
2. What do you mean by Memory Compaction?
  • Combine multiple equal memory holes into one big hole
  • Combine multiple small memory holes into one big hole
  • Divide big memory hole into small holes
  • Divide memory hole by 2
3. Copying a process from memory to disk to allow space for other processes is Called
  • Swapping
  • Deadlock
  • Demand Paging
  • Page Fault
4. Page stealing
  • Is a sign of an efficient system
  • Is taking page frame from other working sets
  • Should be the turning goal
  • Is taking layer disk space for page in page out
5. A spooler is a
  • Location in memory that maintains the contents of documents until it prints out
  • Queue of print job that are waiting to print
  • Program that coordinates the print job that are waiting to process
  • Message sent from the printer to the operating system when a print job is completed
6. What is the method of handling deadlocks?
  • Use a protocol to ensure that the system will never enter a deadlock state.
  • Allow the system to enter the deadlock state and then recover.
  • Pretend that deadlocks never occur in the system
  • All of the Above
7. The Banker’s algorithm is used
  • to rectify deadlock
  •  to detect deadlock
  • to prevent deadlock
  • to slove deadlock
8. All of the following are TRUE regarding virtual memory EXCEPT
  • Any amount of RAM can be allocated to virtual memory
  • The setting for the amount of hard disk drive space to allocate virtual memory can be manually change
  • This temporary storage is called the swap file or page file
  • Virtual memory is the physical space of the hard drive
9. What is dispatch latency?
  • The time taken by the dispatcher to stop one process and start another
  • The time taken by the processor to write a file into disk
  • The whole time taken by all processor
  • None of Above
10. A page fault occurs when
  • the Deadlock happens
  • the Segmentation starts
  • the page is found in the memory
  • the page is not found in the memory
