It can be said that if computation is parallel, it is also concurrent - since parallel computation also fulfills the definition of concurrent computation. Node.js perspective At a high level, Node.js falls into
并行parallel和并发concurrent的区别 http://stackoverflow.com/questions/1050222/concurrency-vs-parallelism-what-is-the-difference Concurrencyis 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 instan...
Concurrent programming is not equivalent to parallel execution, despite the fact that these two terms are often being used interchangeably. Illustration of concurrency without parallelism Concurrency is a property which more than one operation can be run simultaneously but it doesn’t mean it will be...
CPU-bound methods require CPU cycles to do their work and can only run in the background using their own dedicated thread. The number of available CPU cores, limits the number of threads that can run in parallel. The operating system is responsible for switching between the remaining threads,...
In the async iterator space, Javascript has made a very subtle distinction between two types of iterables: concurrent asynchronous iterables and stream asynchronous iterables, referred to hereafter as concurrent iterables and stream iterables, respectively. Each of these types: represent their own ...

Tasks will always start in the order they’re added but they can finish in a different order as they can be executed in parallel. Tasks will run on distinct threads that are managed by the dispatch queue. The number of tasks running at the same time is variable and depends on system ...
However, different paradigms produce different techniques; many parallel programming languages and many verification systems support only one of these two paradigms. Synchronous vs. Asynchronous Systems Another issue is the modelling of a process execution in time. In discrete processes a computation consis...
