What is a race condition?
A race condition occurs when multiple processes access and manipulate shared data concurrently, leading to unpredictable results.
What is the critical-section problem?
The critical-section problem involves ensuring that when one process is executing in its critical section, no other processes can execute in their cri...
What are the three requirements for solving the critical-section problem?
The solution must satisfy mutual exclusion, progress, and bounded waiting.
What is a semaphore?
A semaphore is an integer variable used for synchronization, accessed through atomic operations Wait() and Signal().
What is the difference between a counting semaphore and a binary semaphore?
A counting semaphore can range over an unrestricted domain, while a binary semaphore can only range between 0 and 1.
What is deadlock in the context of semaphores?
Deadlock occurs when processes wait indefinitely for an event that can only be triggered by one of the waiting processes.

What is the dining-philosophers problem? | It is a synchronization problem involving philosophers who must share limited resources (chopsticks) without causing deadlock or starvation. |
How do monitors help in process synchronization? | Monitors encapsulate shared data with procedures, ensuring mutual exclusion without explicit synchronization code. |
What is atomicity in transactions? | Atomicity ensures that a transaction is executed in its entirety or not at all, maintaining data consistency. |
What is serializability in concurrent transactions? | Serializability ensures that concurrent transactions are executed in a way that their results are equivalent to some serial execution. |
