Questions and Answers

What is the term used to describe the situation when concurrent processes are competing for the use of the same resource?

  • Deadlock
  • Resource Competition (correct)
  • Data coherence
  • Process Interaction
  • In the context of mutual exclusion, what does the term 'deadlock' refer to?

  • A situation where processes are unable to proceed because each is waiting for another to release a resource (correct)
  • Processes halting in noncritical sections without interfering with other processes
  • Processes coming into conflict when competing for resources
  • Processes directly communicating with each other
  • What is one of the hardware support methods for achieving mutual exclusion?

  • Cooperation by sharing
  • Data coherence
  • Interrupt Disabling (correct)
  • Timing of process affected
  • What problem must be faced when concurrent processes are competing for the use of the same resource?
