Deadlock Recovery. Once a deadlock is detected, you will have to break the deadlock. It can be done through different ways, including, aborting one or more processes to break the circular wait condition causing the deadlock and preempting resources from one or more processes which are deadlocked
A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, The earliest computer operating systems ran only one program at a time.The ability to take a resource away from a process, have another process use it, and then give it back without the process noticing. It is highly dependent on the nature of the resource. Deadlock recovery through preemption is too difficult or sometime impossible.
