答案 Computer Network Computer network has been playing an increasing role in our day-to-day life. It has brought us a lot of benefits but it can also create some serious problems as well. Computer networks have enabled us to do a lot of things more easily and quickly. For example, we can communicate freely by electronic mails with people from all over the world. It takes only a few seconds to get a message across with the cost substantially lower than that of regular mail. Also, an enormous amount of information can be accessible through the Internet. A fantastic new world will be open to us just by double-clicking the mouse. However, if not managed properly, computer network can create many problems too. Sometimes we spend too much time sorting out the junk mails jammed in our mailbox to do more meaningful things. Furthermore, computer network has become so indispensable for personal contact and public services that once the routine functioning of the system is disrupted or infected by virus, valuable information may be revealed or lost to the detriment of individuals and social institutions. Therefore, the safety of networks has become a growing public concern. All in all, we cannot live without computer networks now. There’s no limit to things computer networks can do. But at the same time we must try to find out new ways to cope with the problems that will arise as it becomes a natural part of our lives.
