Final answer:
A mutex is used to enforce mutually exclusive access to a resource, allowing only one thread at a time to gain access. This is true.
Step-by-step explanation:
T/F: A mutex is used to enforce mutually exclusive access to a resource, allowing only one thread at a time to gain access.
The statement is True. A mutex, short for mutual exclusion, is a synchronization primitive used in concurrent programming to prevent multiple threads from accessing shared resources simultaneously. It ensures that only one thread can acquire the mutex and gain access to the resource at any given time.
This statement is true. In computer science, a mutex, which stands for "mutual exclusion", is a synchronization primitive used to prevent concurrent access to a shared resource by multiple threads or processes. When one thread gains access to a resource by locking the mutex, it prevents other threads from accessing the same resource until the mutex is unlocked. This is essential for ensuring that the threads do not interfere with each other's operations, potentially causing errors or inconsistent states.
When a thread wants to access a shared resource, it must acquire the mutex first. If another thread already holds the mutex, the requesting thread is blocked until the mutex is released. Once the mutex is released, the blocked thread is unblocked and can proceed to acquire the mutex and access the resource.
