What is lock in synchronization?

In computer science, a lock or mutex (from mutual exclusion) is a synchronization mechanism for enforcing limits on access to a resource in an environment where there are many threads of execution. A lock is designed to enforce a mutual exclusion concurrency control policy.Click to see full answer. Similarly, you may ask, what is a lock in Java synchronization?A lock is a thread synchronization mechanism like synchronized blocks except locks can be more sophisticated than Java’s synchronized blocks. Locks (and other more advanced synchronization mechanisms) are created using synchronized blocks, so it is not like we can get totally rid of the synchronized keyword.Additionally, what is mutual exclusion lock? Mutual exclusion locks are a commonly used mechanism for synchronizing processes or threads that need access to some shared resource in parallel programs. They work as their name suggests: if a thread “locks” a resource, another thread that wishes to access it will need to wait till the first thread unlocks it. One may also ask, what is a lock in operating system? < Operating System Design. Wikipedia has related information at Lock (computer science) Locks are methods of synchronization used to prevent multiple threads from accessing a resource at the same time. Usually, they are advisory locks, meaning that each thread must cooperate in gaining and releasing locks.What is a lock and how does it work in general?A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token, coin, etc.), by supplying secret information (such as a number or letter permutation or password), or by a combination thereof or only being able to be opened from
