篇1:人脑与电脑区别的英语作文
The difference between a brain and a computer can be expressed in a single word:complexity.
Even the most complicated computer man has yet built can't compare in intricacy with the brain. Computer switches and comportents number in the thousands rather than in the billions.What's more, the computer switch is just an on-off device,whereas the brain cell is itself possessed of a tremendously complex inner structure.
Can a computer think? That depends on what you mean by “think”. If solving a mathematical problem is “thinking”, then a computer can “think” and do so much faster than a man. Of course, most mathematical problems can be solved quite mechanically by repeating certain straightforward processes over and over again. Even the simple computers of today can be geared for that.
Surely, though, if a computer can be made complex enough, it can be as creative as we are. If it could be made as complex as a human brain, it could be the equivalent of a human brain and do whatever a human brain can do.
But how long will it take to build a computer complex enough to duplicate the human brain? Perhaps not as long as some think. Long before we approach a computer as complex as our brain, we will perhaps build a computer that is at least complex enough to design another computer more complex than itself. This more complex computer could design one still more complex and so on and so on and so on.
In other words, once we pass a certain critical point, the computers take over and there is a “complexity explosion”. In a very short time thereafter, computers may exist that not only duplicate the human brain--but far surpass it.

Some recent developments in computer industry make scientists predict that the gap between human beings and the machine will be closed by the year 0.
To understand the significance of this prediction, let us compare the human brain with existing computers. The brain consumes electrical energy at the rate of 25 watts and occupies volume of one tenth of a cubic foot. The brain houses between 10 billion and 100 billion items of information. Every brain cell is directly connected to many other cells. As a result, the cells in which information is stored can communicate with thousands of other cells. In contrast, the computer consumes 1,000,000 watts of electrical power and occupies hundreds of cubic feet of space. The computer memory is like a cell of pigeonholes, with no thinking capacity and no connections elsewhere.
In a word, the electronic brains can hopelessly succeed in comparison with the human brains.
篇3:关于人脑与电脑作文800字
在科技高速发展的今天,电脑,这个以往时尚的词儿在今时今日似乎已经成了每个有条件的家庭的“重要成员”,可我却不由自主地纠结在一个问题上:人脑,电脑,到底哪个更好?
你或许会觉得这个问题挺无聊,挺幼稚,可在我的眼里,这是个深奥的问题,因为我似乎不能在这两者之间做出抉择,两者都是我所信任的,不能够抛弃的。电脑,是我的“百科老师”,它包罗万象;而我的大脑,是身体的“重要部分”,它指挥着我身体的每一个部位,它助我思考,它让我能有自己的判断……两者都是我所珍惜的,不能失去的。
如果实在要我在两者之间做出选择的话,我可能会更看好后者:人脑。因为归根结底,电脑,它并不属于我们自己本身,它只是一个机器,它没有自己的思想与灵魂,它被造物主创造了出来,并给予了各种各样的功能,让它为人类所用。可这就像一个平凡的人被大家所看好,所信赖,这才成了那个光芒万丈的明星。相反,人脑,它是属于我们自己本身的,它也为我们所用,我们自己可以用大脑来指挥自己要做的任何事,用大脑来认真思考,用大脑来做出正确的判断……
我承认,电脑的确是无所不知、无所不晓的,它上知天文、下知地理;它能歌善舞,能写会画;它精通国画,会下棋,会作文・・・・・・可是,电脑能做到的一切,我们的大脑不也能做到吗?不同的是,电脑不费吹灰之力,轻而易举地就能找到你想要的一切,而我们的大脑,却需要付出艰辛的努力才能够达成目标。
即使这样,我仍旧选择后者,原因不用多说,很简单,不要不劳而获,而要努力奋斗。因为再好的电脑也有坏的那一天,到那时,你所有的心血,和你的重要文件或许都会在顷刻间成为过眼云烟。而你的大脑却不一样了,储存在你大脑里面的知识,只要通过温习,那些知识便会在你的大脑里扎根,永远都不会磨灭。所以,只有靠自己,凭借自己的能力取得成功才能够问心无愧。
我总结出的道理就是:不要过分依赖电脑,它并不属于你自己本身;永远相信你自己的大脑,通过它执着地努力,你取得的成功才是问心无愧,坚信:电脑能做成的一切事,你自己的大脑也一定能做到!
