Concurrency is inherently equivalent to parallelism.

Question

Quizplus · Accepted Answer

Concurrency and parallelism are similar concepts but not interchangeable. Concurrency refers to the ability of multiple tasks to make progress together, whereas parallelism refers to the actual execution of those tasks simultaneously on multiple processors or cores. It is possible to have concurrency without parallelism, such as with time-sharing operating systems, where multiple tasks appear to be executing simultaneously but are actually taking turns using a single processor. Conversely, it is also possible to have parallelism without concurrency, such as with a single task that is divided into multiple threads or processes and executed simultaneously on multiple cores.
