Which of the following is a requirement for a solution to the critical-section problem?

• Resource Allocation

• Data Redundancy

• Process Termination

• Mutual Exclusion

What does the term 'race condition' refer to?

• A type of deadlock

• A memory leak

• A process that is terminated unexpectedly

• Processes competing for resources

In Peterson's solution, what does the 'turn' variable indicate?

• Whose turn it is to enter the critical section

• The number of processes in the system

• The priority of the processes

• The state of the semaphore

What is a mutex lock used for?

• To protect a critical section

• To schedule processes

• To manage memory allocation

• To handle input/output operations

Which of the following is NOT a characteristic of semaphores?

• They can be binary or counting

• They can synchronize process activities

What does the 'wait()' operation do in semaphore usage?

• Increases the semaphore value

• Decreases the semaphore value

• Terminates the process

• Resets the semaphore

What is the purpose of a memory barrier?

• To increase memory speed

• To allocate memory dynamically

• To ensure memory changes are visible to all processors

• To prevent memory leaks

Which of the following is a property of the compare-and-swap instruction?

• Can be interrupted

• Executed atomically

• Is non-atomic

• Requires multiple steps

What is a monitor in the context of synchronization?

• A method for memory allocation

• A low-level hardware instruction

• A type of semaphore

• A high-level abstraction for process synchronization
