Question: where two or more processes are waiting indefinitely for an event that can be caused only by one of the waiting processes is called.
Answer:
The implementation of a semaphore with a waiting queue may result in a situation where two or more processes are waiting indefinitely for an event that can be caused only by one of the waiting processes. The event in question is the execution of a signal() operation. When such a state is reached, these processes are said to be deadlocked.
