Also known as
Mutual Exclusion Lock Binary Semaphore

Create a lock which only allows a single thread to access a resource at any one instant.
Applicability
Use a Mutex when
- you need to prevent two threads accessing a critical section at the same time
- concurrent access to a resource could lead to a race condition
