Can you remember the first time you learned to ride a bike or drive a car？Learning these skills changed your life forever and opened up new horizons（视野）. Learning about puters can be like learning how to ride a bike or drive a car. Once you have invested the time to master the skills，you will never go back to the old days. The new technology is simply too convenient and too powerful.
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 puter. It extends the capabilities of our minds.
Computers have saved organizations millions of dollars. Furthermore，these same puter systems have opened up new opportunities that would have gone undiscovered or neglected. The puter may multiply what we can do，and the return on investment is high. The growth of puter usage is surprising. On the other hand，the puter can do serious damage. Invasion of privacy（侵犯隐私），fraud（欺诈），and puter-related mistakes are just a few shocking examples.The puter 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 puter systems will you be able to avoid the dangers while enjoying the many，many benefits of the puter age.
