1、The Computer and the Human BrainNowadays the computer plays an increasingly important role in our work and life. It seems that we can do anything with a computer: writing articles, drawing pictures, listening to music, playing games, and so on. Therefore, it is often assumed that the computer is a g
2、reat deal superior to the human brain. But in fact, the human brain can beat the computer in many ways, especially in the complexity of structure, the flexibility of memory, and the creativity of thinking.First of all, the human brain is far more complex than the computer. Small as it is, the human
3、brain “contains about ten billion neurons and a hundred billion smaller cells,” which are interconnected in a vastly complicated network that even the most advanced computers cannot rival, for the computer is make up of only a certain number of chips and components. Although scientists have tried to
4、 make computers that can function exactly like the human brain, no one has ever succeeded, for the complex human brain is beyond any human ability to duplicate.Secondly, the human brain also surpasses the computer in the flexibility of memory. Although the computer is much better in accuracy and lia
5、bility than the human brain, for it can remember any date without making mistakes so long as the program works well, it can only work along a linear preset path, and will be at a loss when something unexpected happens. Besides, no matter how well it remembers, it can only memorize things input by hu
6、man beings. And once the data are deleted, it can remember nothing at all. In contrast, the memory of the human brain is multi-dimensional, and can deal with information flexibly. It is like an ever-flowing fountain, full of changes and possibilities, and will never go dry, while the computer is jus
7、t like a warehouse, the capacity of which is limited.Thirdly, the computer cannot rival the human brain in creativity. Human beings can write great symphonies, or conceive scientific theories. It is said that computers can do translations, but up to now, none of the translation software is able to t
8、ranslate a simple sentence as faithfully and smoothly as human beings do, not to say a complicated article. Although the computer can do some “creative” to some degree, such as playing chess, it can do so only when it is thus programmed. Computers can never surpass the human brain in creativity.The
9、speed of the computer is tremendously faster than that of the human brain, but it is created by the human brain, and only such a brilliant organism as the human brain can achieve such a brilliant speed. The computer can never surpass the human brain in many ways. It is only a tool made by human bein
