问题描述

什么是一个协程和一个线程

What are the differences between a "coroutine" and a "thread"?

推荐答案

是协同程序顺序处理的一种形式：只有一个在任何给定时间（就像子程序AKA程序正在执行AKA功能 - 他们只是通过每个之间的接力棒其他更流畅;-)。

Coroutines are a form of sequential processing: only one is executing at any given time (just like subroutines AKA procedures AKA functions -- they just pass the baton among each other more fluidly;-).

线程是（至少在概念上）并行处理的形式：多个线程可在任何给定的时间被执行。 （传统上，在单CPU，单核的机器，这是并发模拟从OS一些帮助 - 现在，既然有这么多机器多CPU和/或多核，线程会的事实上的被simulaneously执行，不只是概念; - ）

Threads are (at least conceptually) a form of concurrent processing: multiple threads may be executing at any given time. (Traditionally, on single-CPU, single-core machines, that concurrency was simulated with some help from the OS -- nowadays, since so many machines are multi-CPU and/or multi-core, threads will de facto be executing simulaneously, not just "conceptually";-).
