Deadlock Handling in Operating System | Prevention, Avoidance, Detection & Recovery

In this comprehensive tutorial, we dive deep into Deadlock Handling in Operating Systems. A deadlock is a situation where a set of processes are blocked because each process is holding a resource and waiting for another resource acquired by some other process. ​What you will learn in this video: ​Deadlock Characterization: Understanding the four necessary conditions (Mutual Exclusion, Hold and Wait, No Preemption, and Circular Wait). ​Deadlock Prevention: How to design a system so that at least one of the necessary conditions for deadlock cannot hold. ​Deadlock Avoidance: Using algorithms like the Banker’s Algorithm and Resource-Allocation Graphs with Claim Edges to ensure the system stays in a "Safe State." ​Deadlock Detection: How to use a "Wait-for Graph" to identify cycles and detect deadlocks in a system. ​Recovery from Deadlock: The two primary methods—Process Termination (aborting processes) and Resource Preemption (forcibly reallocating resources). ​Key Topics Covered: ​Safe State vs. Unsafe State ​Resource Allocation Graph (RAG) ​Strategies for Deadlock Recovery Comparison between Prevention and Avoidance Key Highlights: [00:01] Introduction to Deadlock Handling [05:30] Deadlock Prevention Strategies [12:15] Deadlock Avoidance & Safe States [18:45] Recovery Methods: Termination vs. Preemption Whether you are preparing for university exams or a technical interview, this video provides a clear and structured explanation of how Operating Systems manage and resolve deadlocks efficiently.
