while N others sleep or await I/O." Python threads can also wait for a threading.Lock or other synchronization object from the threading module; consider threads in that state to be "sleeping," too.
In addition to locks, Python threading module supports semaphores, which offering another synchronization technique. It is one of the oldest synchronization techniques invented by a well-known computer scientist, Edsger W. Dijkstra.The basic concept of semaphore is to use an internal counter which is...
In multi-threaded systems, atomic variables ensure thread safety and synchronization. They provide methods like ‘get()’, ‘set()’, ‘incrementAndGet()’, and ‘compareAndSet()’, among others, that can be used to perform atomic actions without the need for explicit locking. This makes ...

Note that both ConcurrentStack and ConcurrentQueue classes are thread safe and they can manage locking and synchronization issues internally. You can also convert the concurrent queue instance to an array by making a call to the ToArray() method. The following code snippet illustrates how ...
All Java programs are compiled into class files that contain bytecodes, the machine language of the Java virtual machine. In this JavaWorld classic, Bill Venners goes under the hood of the JVM to explain the mechanics of thread synchronization, including

A thread acquires anexclusive lockon a shared resource by entering a waitingmonitor object. When the thread is done, it calls a wait method. The mutually exclusive (mutex) locking mechanism waits aresynchronized, which serves as a “token” or lock. ...
