Deadlock Detection in OS In deadlock detection, the operating system considers that a deadlock situation will occur and then it will identify it. No methods for prevention or avoidance of deadlocks are applied here. So, the OS analyses if there is a deadlock. If detected, recovery methods a...

recovery, where the system identifies existing deadlocks and takes corrective actions to resolve them dynamically. Another approach is resource allocation strategies such as deadlock avoidance, which involves careful resource request analysis to ensure a safe state and prevent the possibility of future ...

In this tutorial, we will be covering the concepts of Deadlock detection and recovery. If a system does not employ either a deadlock-prevention or deadlock-avoidance algorithm, then there are chances of occurrence of a deadlock. In this case, the system may provide two things: ...
a combination of these techniques might be used in a hierarchical approach. For example, process termination might be used as a first resort, followed by resource preemption if possible, and finally, rollback as a last resort. Additionally, prevention and avoidance techniques are often preferred ov...
