Deadlock Prevention and Deadlock Avoidance

Deadlock prevention and deadlock avoidance are two different strategies used to handle the problem of deadlocks in a computer system.

Deadlock Prevention

In deadlock prevention, the system tries to prevent deadlocks from occurring by ensuring that the four necessary conditions for deadlock do not occur. These conditions are mutual exclusion, hold and wait, no preemption, and circular wait. If any of these conditions are violated, the request for resources is always granted if the resulting state is safe. Deadlock prevention is considered to be a more restrictive approach than deadlock avoidance.

Deadlock Avoidance

In deadlock avoidance, the system tries to avoid deadlocks by predicting and preventing the occurrence of a deadlock before it actually happens. This is done by using techniques such as resource allocation graphs or banker's algorithm. In this approach, the request for resources is always granted if the resulting state is safe. Deadlock avoidance is considered to be less restrictive than deadlock prevention.

The Answer

The statement that is not true of deadlock prevention and deadlock avoidance schemes is option A, which states that in deadlock prevention, the request for resources is always granted if the resulting state is safe. This statement is incorrect because in deadlock prevention, the request for resources is not always granted even if the resulting state is safe. Deadlock prevention may require the system to deny the request for resources in order to prevent the occurrence of a deadlock.

Deadlock prevention scheme handles the dead lock by confirms that either of the four necessary condition for deadlock doesn’t occur. Hence a resource request may not be granted even if the resulting state is safe.
