Unit IV: Deadlock – Operating System

Deadlock is a situation which involves the interaction of more than one resources and processes with each other.

We can visualize the occurrence of deadlock as a situation where there are two people on a staircase. One is ascending the staircase while the other is descending. The staircase is so narrow that it can only fit one person at a time.

In this “Deadlock – Operating System” you will learn about the following topics:

1. System Model
2. System Resources
3. Preemptable, Non-Preemptable
4. Conditions for Resources Deadlock
5. Mutual Exclusion, Hold and Wait, No Preemption, Circular Wait
6. Deadlock Modeling
7. Ostrich Algorithm
8. Methods of Handling Deadlocks
9. Deadlock Prevention
10. Elimination of “Mutual Exclusion” Condition
11. Elimination of “Hold and Wait” Condition
12. Elimination of “No-preemption” Condition
13. Elimination of “Circular Wait” Condition
14. Deadlock Avoidance
15. Banker’s Algorithm (Single Resource)
16. Banker’s Algorithm (Multiple Resources)
17. Deadlock Detection
18. Resource Allocation Graph
19. Recovery from Deadlock
20. Recovery Through Preemption
21. Recovery Through Rollback
22. Recovery Through Killing Processes
23. Starvation
24. Difference between Deadlock and Starvation
