3. Remembering the discussion of deadlocks, if you were designing a networked system, how would you manage the treat of deadlocks in your network? Consider all of the following: prevention, detection, avoidance, and recovery.


· Deadlock Prevention:
Preventing deadlocks by constraining how requests for resources can be made in the system and how they are handled (system design).
The goal is to ensure that at least one of the necessary conditions for deadlock can never hold.



· Deadlock Avoidance:
The system dynamically considers every request and decides whether it is safe to grant it at this point,
The system requires additional apriori information regarding the overall potential use of each resource for each process.
Allows more concurrency.

and a police officer directing traffic.
