    与电脑相比,人脑的数据存贮量约为1PB(Petabyte,拍字节或千万亿字节或千T字节,1PB = 1,048,576 GB = 1,073,741,824 MB)。在执行容易简单地分为一步一步的操作命令方面,电脑比人脑更强,而在不易分为简单步骤的处理任务方面,人脑更强。

 

How powerful is the human brain compared to a computer?

For as fast and powerful as computers have become, they still pose no match for the human brain. Sure, a computer specifically programmed to perform singular task such as, say, playing chess can give a human a run for his or her money, but when we measure a computer against the entirety of what a human mind is capable of, it’s not really all that close. Over the past few years, scientists, in a variety of ways, have tried to get a super computer to mimic the complexity and raw processing power of the human brain. According to biologists, the human brain has approximately 90 billion nerve cells which are linked together by, quite literally, trillions of connections called synapses.
