Question
Which of the following conditions is NOT required for a
deadlock to occur?Solution
Deadlock occurs when four specific conditions are met simultaneously: mutual exclusion, hold and wait, no preemption, and circular wait. Infinite loops in processes are not a prerequisite for deadlock, as deadlock refers to resource contention, not process logic errors.
- Deadlock Conditions:
- Mutual Exclusion: Only one process can use a resource at a time.
- Hold and Wait: A process holding resources waits for additional ones.
- No Preemption: Resources cannot be forcibly taken.
- Circular Wait: Processes form a cycle, each waiting for a resource held by the next.
