The Importance of Computers
Since computers were invented in the USA in the 1950s, they have become very important in many areas of work and leisure. There is no doubt that computers are very useful in technology and business.

They can do work that is dangerous to humans.
In business, computers are used to place and cancel orders. They are also making the workplace safer and better.
Since the Internet came into being, people’s lives at home have been changed, too. More and more people have personal computers that are used to play games and watch movies. Thanks to the Internet, people can do shopping and do business at home. Instead of writing letters on paper, people communicate by sending e-mails and chatting online. The whole world is connected. The Internet is making the world smaller, like a village.
Computers have improved our lives, but they have brought problems, too.

Besides, not everything we read on the Internet is true or good for us. Computers help us at work and at home, but they must be used properly.
