    Wikpedia puts it nicely:

    "The concept of concurrent computing is frequently confused with the related but distinct concept of parallel computing,[3][4] although both can be described as “multiple processes executing during the same period of time”. In parallel computing, execution occurs at the same physical instant: for example, on separate processors of a multi-processor machine, with the goal of speeding up computations—parallel computing is impossible on a (one-core) single processor, as only one computation can occur at any instant (during any single clock cycle).[a] By contrast, concurrent computing consists of process lifetimes overlapping, but execution does not happen at the same instant. "

      You’re still missing the point. We all understand that definition. We’re just saying that it is incorrect use of the word “concurrent”. Does that make sense? The word “concurrent” means things happening at the same time. It’s stupid for programmers to redefine it to mean things not happening at the same time.

        execution = if concurrency then parallelism else multitasking
        

        Simple. Easy. But it doesn’t confuse my boss or make everyone angry.

        concurrency = if concurrency then concurrency else concurrency 
        

        Now this I can work with.
