Preemption which means to free up some number of resources from one running process and give it to another one that. 7 3 methods for handling deadlocks. If one has then the system must attempt to recover from the deadlock.

If deadlock prevention and avoidance are not done properly as deadlock may occur and only things left to do is to detect the recover from the deadlock. Deadlock recovery performs when a deadlock is detected. When deadlock detected then our system stops working and after the recovery of the deadlock our system start working again.

Deadlock can be detected by the resource scheduler as it keeps track of all the resources that are allocated to different processes. If all resource types has only single instance then we can use a graph called wait for graph which is a variant of resource allocation graph. Details about these are given as follows deadlock detection.
