Questions and Answers

Which synchronization tool allows processes to synchronize their activities in a more sophisticated way than Mutex locks?

  • Critical Section
  • Busy Waiting
  • Spin Locks
  • Semaphore (correct)

    • What is the purpose of Mutex locks in a system?

  • To increase the complexity of synchronization
  • To protect critical sections of code (correct)
  • To keep processes waiting indefinitely
  • To execute all processes simultaneously

    • What does S=0 signify in the context of Semaphore usage?

  • The process is terminated
  • The Semaphore is in a busy state (correct)
  • The Semaphore is locked
  • The process can proceed without any restrictions

    • What is a common issue associated with Mutex locks that is also known as 'SPIN LOCK'?
