To being with, commutation by computer has caused some problems. We can easily receive a message; both wanted and unwanted, in just few minutes. The researcher Paul Hasenrader has found out a line manager received between 300-400 messages a day.  Manager has to read though them, because he doesn’t want to miss anything important for a story his working on. It took him several hours to read them. But most of them were junk mail, just few important. “People spend all day shuffling these bloody messages back and forth,” George Jones a chairman of Portman Mining pointed out. Our expanded ability to communicate means, that anyone with a computer can communicate anything to anyone on any subject at any time. In addition to problems in computer have also caused problems in business. The computer via Internet access has created excellent opportunities for computerized crime. Computer hackers use their skills to obtain secret business information and to steal money. For example, Yueqing Zhang a computer hacker from Hong Kong obtained twenty thousand usable credit card numbers by breaking into the computer files of a credit card company. He also erased the accounting records of another big company before he was caught and arrested. Banks worry that hackers will learn how to transfer money out of customers’ accounts into their own. “So far, we have been able to stay one step ahead of the hackers in this particular game,” said by bank spokesperson Qiongxi Wong. Anyhow the security is never one hundred percent in any business, especial via the Internet access.

 

These examples show that the computer has created problems as well as benefits in

the area of communication. A computer-literate child can receive pornographic photos and listen to chat room conversations about sex; but it also can help people to get various useful data and information just by few seconds. All in all, it is clear that computers and Internet access have made our lives easier, but they have done at a cost.
