Question:
Which state occurs when two or more processes are waiting indefinitely for an event that can be caused only by one of the waiting processes?
Which state occurs when two or more processes are waiting indefinitely for an event that can be caused only by one of the waiting processes?
Show Hint

- Deadlock state
- Synchronisation state
- Resource allocation state
- Preemption state
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Deadlock occurs when a set of processes are blocked because each process is holding a resource and waiting for another resource held by another process.
Step 1: Analyze given condition.
• Processes are waiting indefinitely
• Event depends on another waiting process
Step 2: Compare with definitions.
• Deadlock → Circular waiting condition
• Synchronisation → Coordination, not blocking
• Resource allocation → General term
• Preemption → Resource taking mechanism
Step 3: Conclusion. \[ \boxed{(1)\ \text{Deadlock state}} \]
