Ans.Deadlock prevention techniques aim to eliminate or avoid the occurrence of deadlocks, but they cannot guarantee complete elimination in all scenarios. The effectiveness of prevention strategies depends on the system design, resource allocation policies, and the behavior of processes. In complex and ...

Deadlock prevention Programmers can preventdeadlockby disciplined observance of some policy that guarantees that at least one of the prerequisites of deadlock (mutual exclusion, hold and wait, no preemption of the resource, and circular wait) can never occur in the system. The mutual exclusion con...
