    Question 2

    There are three processes P1, P2 and P3 sharing a semaphore for synchronizing a variable. Initial value of semaphore is one. Assume that negative value of semaphore tells us how many processes are waiting in queue. Processes access the semaphore in following order : (a) P2 needs to access (b) P1 needs to access (c) P3 needs to access (d) P2 exits critical section (e) P1 exits critical section The final value of semaphore will be :

    • A
      0
    • B
      1
    • C
      -1
    • D
      -2

      20 KHz
    • C
      5 KHz
    • D
      5 MHz
