Semaphore

A semaphore is a flag used to insure than events are atomic. . Just like a railroad semaphore, the flag provides a signal to one train if another is approaching, helping the conductors of the train avoid a train wreck.
The same is true for software processes that share memory, files, or other software artifacts. A semaphore is used in interprocess communications to insure that there are no 'train wrecks' between software processes.
