18 Questions
Which synchronization tool allows processes to synchronize their activities in a more sophisticated way than Mutex locks?
Semaphore
What is the purpose of Mutex locks in a system?
To protect critical sections of code
What does S=0 signify in the context of Semaphore usage?
The Semaphore is in a busy state
What is a common issue associated with Mutex locks that is also known as 'SPIN LOCK'?
Busy Waiting
Which atomic operations can be used to access a Semaphore variable S?
Wait() and Signal()
In the context of synchronization tools, what does 'Mutex' stand for?
'Mutual Exclusion'
What is the main objective of process synchronization?
To prevent inconsistent data due to concurrent access
Which of the following is NOT a synchronization technique used in a multi-process system?
Registers
What is the critical-section problem primarily concerned with?
Ensuring the consistency of shared data
Why is synchronization necessary in a multi-process system?
To ensure data consistency and integrity
What happens if the order of execution of cooperating processes is not preserved?
Con icts in execution
Which term describes a process that can affect the execution of other processes?
Cooperative process
What is the purpose of process synchronization?
To ensure the orderly execution of cooperating processes
Which statement best describes the producer-consumer problem?
It is a problem where the producer and consumer processes must access shared buffers in a coordinated manner to avoid data inconsistency
What is the purpose of the integer counter in the producer-consumer solution?
To keep track of the number of full buffers
What is a disadvantage of using a hardware-based solution for process synchronization?
Implementing atomic instructions like TestAndSet() on multiprocessors is not a trivial task for hardware designers
What is meant by the statement "Concurrent access to shared data may result in data inconsistency"?
Multiple processes accessing shared data simultaneously without proper synchronization can lead to data corruption or inconsistent data
Which statement best describes the role of the lock variable in the producer-consumer solution?
It is used to ensure that only one process (producer or consumer) can access the shared buffers at a time
