Asynchronous programming

If we try to define asynchronous programming, we come up with something that states that it's a programming approach in which computations, which can be tasks or threads, execute outside of the basic program flow. In programming terminologies, these computations execute on different call stacks, not the current one. Because of this, it's possible for us to think of more than one async computation happening at the same time; we can wait for each to happen so that aggregation of a result or some other result manipulation is possible.

Up until now, we've looked at three of these terminologies such as concurrency, multithreading, and asynchronous. We tend to confuse these but given our discussions, it's clear that asynchronous subsumes concurrency and not multithreading. We know that asynchrony can be achieved using scheduling:
