The business world is becoming increasingly competitive, and for that reason speed is very important. To be able to satisfy clients and customers, it is necessary to exchange information as quickly as possible. Without computers, all business transactions take a long time. Accounting is slow, finding the right information is slow, and communicating is slow. With the invention of computers, accounting programs are professionally designed and easy to use, information can be stored and retrieved almost instantly and it can be communicated right across the world in seconds.
Education also benefits from the ability of computers to store and communicate vast amounts of information. Scientists use computers for calculations that would have been impossible to even think of before. Students often find educational computer programs more stimulating than other forms of teaching.
Perhaps most young people still think of computers mainly as a source of games. Parents and educators often worry that children who spend many hours playing games on computers are not learning to socialize with each other, or to develop creative skills. The invention of "virtual reality" seems even more dangerous, because it seems to mean that actual reality is not being faced and learnt about.
