解放军文职招聘考试电脑的巨大作用和学会电脑的益处

Technological developments through the years have enabled us to do more with less effort. We have continuously looked for better ways of doing things. Each invention and new development has allowed us to extend our capabilities. Today we see one of the most dramatic technologies ever developed—the computer. It extends the capabilities of our minds. 

Computers have saved organizations millions of dollars. Furthermore, these same computer systems have opened up new opportunities that would have gone undiscovered or neglected. The computer may multiply what we can do, and the return on investment is high. The growth of computer usage is surprising. On the other hand, the computer can do serious damage. Invasion of privacy(侵犯隐私), fraud(欺诈), and computer-related mistakes are just a few shocking examples. 

The computer is like a double-edged sword. It has the ability to cut us free from some activities, but it can also cut deep into profits, personal privacy, and our society in general. How it is used is not a function of technology. It is strictly a function of how people decide to use or misuse this new technology. The choice is yours, and only through a knowledge of computer systems will you be able to avoid the dangers while enjoying the many, many benefits of the computer age.
