• Circular Wait

• Resource Sharing

What does the term 'Circular Wait' refer to in the context of deadlock?

• Processes waiting for resources in a circular chain

• Resources being shared among processes

• Processes executing in a loop

• A method of resource allocation

Which method is used to handle deadlocks by ensuring that at least one of the necessary conditions is not met?

• Deadlock Detection

• Deadlock Ignorance

• Deadlock Prevention

• Deadlock Recovery

What is the purpose of the Banker's Algorithm?

• To recover from deadlocks

• To detect deadlocks

• To allocate resources safely

• To ignore deadlocks

In deadlock recovery, what does 'Resource Preemption' involve?

• Ignoring the deadlock situation

• Automatically recovering from deadlocks

• Selecting which resources to take from processes

• Choosing which processes to terminate

What is a 'Safe State' in the context of deadlocks?

• A state where resources are fully allocated

• A state where all processes are executing

• A state where processes are waiting indefinitely

• A state where no deadlocks can occur

Which of the following is an example of a deadlock situation?

• Two trains on the same track

• A system running multiple applications

• A process waiting for user input

• A single process using multiple resources

What does 'Deadlock Ignorance' imply?

• Ignoring the possibility of deadlocks

• Automatically resolving deadlocks

• Detecting deadlocks manually

• Preventing deadlocks from occurring

Which condition states that a resource cannot be forcibly taken from a process?
