Concurrency vs Parallelism

• Concurrency vs. Parallelism

• Difference between a coroutine and a thread?

• Why the Confusion Exists

• What is the difference between concurrency and parallelism?

  Concurrency is when two or more tasks can start, run, and complete in overlapping time periods. It doesn't necessarily mean they'll ever both be running at the same instant. For example, multitasking on a single-core machine.

  Parallelism is when tasks literally run at the same time, e.g., on a multicore processor.
