Questions and Answers

What is a deadlock in an operating system?

  • A situation where processes are running concurrently without any resource allocation
  • A situation where processes are terminated due to resource unavailability
  • A situation where processes are waiting for resources but not holding any
  • A situation where processes are blocked because each process is holding a resource and waiting for another resource acquired by some other process (correct)

    • Which condition can lead to deadlock in a system?

  • Sequential execution
  • Exclusive access
  • Preemptive resource allocation
  • Circular wait (correct)

    • What does the 'hold and wait' condition for deadlock entail?

  • Processes release all resources before requesting new ones
  • All processes are holding all available resources without waiting for any additional resources
  • No process is holding any resources and all are waiting for resources
  • A process holding at least one resource is waiting to acquire additional resources held by other processes (correct)
