Can someone explain the exact definition of concurrency in simple terms? or What’s the real-world def

Think of concurrency as a solo artist playing multiple instruments in a sequence so fast it sounds like a band. Parallelism is the actual band playing together.

The definition of concurrency (lol, concurrency*) gets fuzzy in edge cases, but that’s the gist.

For more, the Java `Concurrency` docs are surprisingly readable!
