推荐答案

非常简单.
通常，您从同步呼叫开始.这意味着我开始执行任务，然后等待任务完成.
异步时，您有一个开始和结束方法来执行任务.您启动了begintask，该任务可以在完成后立即调用endtask.当该任务运行(在单独的线程中)时，可以完成其他任务.

very simple.
normally you begin with synchronous calls. This means I start a task and wait for the completion of the task.
When going async you have a begin and an end method for a task. You start the begintask and that task can call the endtask as soon as it is finished. While that task runs (in a separate thread) other tasks can be done.
