A deadlock avoidance algorithm dynamically examines the __________ to ensure that a circular wait condition can never exist.

A. Resource allocation state
B. System storage state
C. Operating system
D. Resources

Explanation: Resource allocation states are used to maintain the availability of the already and current available resources.

Each request requires that the system consider the _____________ to decide whether the current request can be satisfied or must wait to avoid a future possible deadlock.

A. Resources currently available
B. Processes that have previously been in the system
C. Resources currently allocated to each process
D. Future requests and releases of each process

A state is safe, if ____________

A. The system does not crash due to deadlock occurrence
B. The system can allocate resources to each process in some order and still avoid a deadlock
C. The state keeps the system protected and safe
D. All of the mentioned

A system is in a safe state only if there exists a ____________

A. Safe allocation
B. Safe resource
C. Safe sequence
D. All of the mentioned

All unsafe states are ____________

A. Deadlocks
B. Not deadlocks
C. Fatal
D. None of the mentioned

If no cycle exists in the resource allocation graph ____________

A. Then the system will not be in a safe state
B. Then the system will be in a safe state
C. All of the mentioned
D. None of the mentioned

The resource allocation graph is not applicable to a resource allocation system ____________

A. With multiple instances of each resource type
B. With a single instance of each resource type
C. Single & multiple instances of each resource type
D. None of the mentioned

The Banker’s algorithm is _____________ than the resource allocation graph algorithm.

A. Less efficient
B. More efficient
C. Equal
D. None of the mentioned
