Questions related to teaching concurrency and concurrent programming, as well as teaching various methods of creating concurrent operations.
Concurrency is the measure to which the order of execution of units or tasks in an algorithm or program changes the result.
Concurrent tasks are order-independent, which enables parallel execution of tasks, without affecting the outcome.
Concurrent programming can involve dynamic methods of communication. Concurrency is meant, in part, to achieve a correct outcome (one that is always the same for some input). Concurrent systems such as Operating systems and Database management systems are generally designed to operate indefinitely, including automatic recovery from failure, and not terminate unexpectedly.
