Operating Systems Quiz: Deadlock & Banker’s Algorithm

What is the primary function of an operating system?

• To manage hardware and software resources

• To create applications

• To provide internet access

• To enhance graphics performance

Which condition is NOT a necessary condition for a deadlock to occur?

• Circular Wait

• No Preemption

• Resource Sharing

• Hold and Wait

What does the term 'Mutual Exclusion' refer to in the context of deadlocks?

• Only one process can use a resource at a time

• Resources can be shared

• Resources are always available

• Processes can run simultaneously

Which of the following is a method of deadlock prevention?

• No preemption

• Allowing hold and wait

• Imposing a total ordering of resources

• Allowing circular wait

What is the purpose of the Banker’s Algorithm?

• To allocate memory

• To avoid deadlocks

• To detect deadlocks

• To recover from deadlocks

Which of the following is a strategy for deadlock recovery?

• Resource allocation

• Process termination

• Resource sharing

• Circular wait

What does 'Hold and Wait' mean in the context of deadlocks?

• Processes must release all resources before requesting new ones

• Resources are always available

• Processes cannot hold any resources

• Processes can hold resources while waiting for others

In the context of deadlock avoidance, what is required from processes?

• No resource requests

• Knowledge of future resource requests

• Immediate resource allocation

• Random resource requests

What is a key term associated with deadlock detection?

• Resource allocation

• Resource sharing

• Circular wait

• Safe state

Which of the following describes a 'Safe State'?

• A state where all processes can finish without deadlock

• A state where resources are fully allocated

• A state where deadlock is possible

• A state where processes are indefinitely waiting
