A measure of how sequential a program is The ability of an operating system to divide tasks into smaller subtasks The ability of different parts of a program, algorithm, or problem to be executed out-of-order or in partial order The process of synchronizing data between multiple operating systems 2/10 What is synchronization? The process of running multiple instances of a program simultaneously The coordination of multiple threads or processes to achieve a specific outcome or consistency The ability of an operating system to handle multiple user requests The process of optimizing program execution time through parallel computing 3/10 What is a critical section in the context of concurrency? A section of code that must be executed with multiple threads or processes simultaneously A section of code that requires exclusive access to shared resources and must be executed atomically A section of code where synchronization is not required A section of code that is only executed during system startup 4/10 What is a race condition? A situation where the order of execution of concurrent events affects the final outcome of a program A situation where multiple threads or processes are scheduled to execute at the same time A situation where synchronization between multiple threads or processes fails A situation where a program consumes excessive system resources 5/10 What is a semaphore in synchronization? A synchronization primitive that controls access to a common resource in a concurrent system A type of concurrent programming language A measure of the memory usage of a program A technique used for parallel process execution on a computer cluster 6/10 Which of the following is NOT a form of synchronization mechanism in operating systems? Mutex Condition variable Semaphore Polling 7/10 What does the producer-consumer problem illustrate? The need for process scheduling algorithms The problem of coordinating multiple threads or processes accessing a shared buffer The process of memory management in virtual memory systems The concept of parallel processing in multi-core systems 8/10 What is deadlock in synchronization? A state where two or more processes in a system are unable to proceed because each is waiting for the other to release a resource A situation where multiple threads or processes share data without proper synchronization The process of terminating an operating system when it becomes unresponsive The process of allocating system resources to processes or threads 9/10 What is the main goal of synchronization in operating systems? To maximize processor utilization To minimize memory consumption To ensure the correct and orderly execution of concurrent threads or processes To optimize program execution time 10/10 Which of the following is NOT a concurrency control problem? Deadlock detection Race condition prevention Starvation avoidance Thread prioritization
