In a busy restaurant, two chefs, Grace and Noah, are trying to prepare their signature dishes. Chef Grace needs a special pan that Chef Noah is currently using, while Chef Noah needs the same pan to finish his dish. What is a necessary condition for a deadlock to occur in this situation?

• Preemption

• Mutual exclusion

• Starvation

• Priority scheduling

In a busy office, several employees are trying to use the printer, but only one person can use it at a time. Each employee is currently working on their own tasks and holding onto their documents. If one employee is waiting for the printer while another is using it, and they are all waiting for each other to finish, which of the following are among the four necessary conditions for a deadlock? (Select all that apply)

• Mutual exclusion

• Resource holding

• Spooling

• Circular wait

What is starvation in process management?

• System-wide freeze
• Two processes deadlocking
• A process waiting indefinitely for resources
• A type of scheduling algorithm

Which of the following are deadlock handling strategies? (Select all that apply)

• Prevention
• Detection
• Avoidance
• Recovery

In a traffic jam analogy, what does each car represent in the context of deadlock modeling?

• Resource
• Process
• Deadlock
• Semaphore

In the spooling deadlock case, what causes the deadlock?

• Printer failure
• Insufficient spool area for all jobs
• Power outage
• Job priority mismatch

Which one is not one of the four conditions of deadlock?

• No preemption
• Starvation
• Circular wait
• Resource holding

What is the role of the Banker's Algorithm?

• Deadlock detection
• Deadlock avoidance
• Process synchronization
• Disk scheduling

What is a characteristic of a deadlock situation?

• Processes continue to run indefinitely

• Processes are unable to proceed due to resource contention

• Processes complete their tasks successfully

• Processes are terminated by the system
