Questions and Answers

What is a deadlock in a multiprogramming environment?

  • A situation where a waiting process is never able to change state because the resources it has requested are held by other waiting processes (correct)
  • A situation where all processes are in a waiting state and unable to make progress
  • A process requesting resources that are not available at that time
  • A set of blocked processes each holding a resource and waiting to acquire a resource held by another process in the set
  • In the context of the example provided, what represents a resource in the bridge crossing scenario?

  • The number of cars waiting to cross the bridge
  • The number of cars on the bridge
  • Traffic direction
  • Each section of the bridge (correct)
  • What is a possible consequence of a deadlock in the bridge crossing example?

  • Increased traffic in one direction
  • Starvation of cars waiting to cross the bridge (correct)
  • Faster movement of cars on the bridge
  • Smooth flow of traffic across the bridge
