Also to know is, how does a mutex work?The idea behind mutexes is to only allow one thread access to a section of memory at any one time. If one thread locks the mutex, any other lock attempts will block until the first one unlocks. But what if the second mutex is reading at the same time the first is writing.Also Know, what is mutex lock in operating system? Mutex. Mutex is a mutual exclusion object that synchronizes access to a resource. It is created with a unique name at the start of a program. The Mutex is a locking mechanism that makes sure only one thread can acquire the Mutex at a time and enter the critical section. In respect to this, what is lock contention? Lock contention takes place when a thread tries to acquire the lock to an object which is already acquired by other thread*. Until the object is released, the thread is blocked (in other words, it is in the Waiting state).What is the difference between a mutex and a semaphore?The difference between a mutex and a semaphore is that only one thread at a time can acquire a mutex, but some preset number of threads can concurrently acquire a semaphore. That’s why a mutex is sometimes called a binary semaphore. A mutex is used for mutual exclusion.
