Introduction
Now think of a human brain as CPU and it is doing multitasking. This is for sure that a human can perform multiple activities at a time, for example a person listening to a radio while typing a email. In other example a journalist listening to a statesman as well as noting down the speech in his notebook. Surely this is multitasking. But we talk about the brain’s ability to pay attention on multiple things at a time, it is quite impossible. In the above two examples both the persons do the context switching back and forth between the two activities. If it happens like, the journalist put complete focus on writing for few seconds more he may miss some dialogs of the statesman and vice versa.
景区简介
现在想一个人类大脑的CPU和它做任务。这是肯定的，一个人可以执行多种活动的时间，比如一个人听收音机而输入电子邮件。在其他的例子，一个记者听一个政治家以及记下讲话在他的笔记本。这真是多。但我们谈论大脑的注意能力对多个事物的时间，这是完全不可能的。在上述两个例子的人做了上下文之间来回切换这两个活动。如果它发生，记者把完整的重点写了几秒钟，他可能会错过一些对话的政治家，反之亦然。
