  3. Computers have already revolutionized the way we live and work. But it is only early days for computers. We don’t know how much they are still changing the world. • The problem Will computers change our life in future for the better orthe worse?

  4. History of computersThe first mass PC • The first personal computer was the Datapoint 2200, a mass – produced programmable terminal, announced by Computer Terminal Corporation (CTC) in June, 1970. It was equipped to perform any task a simple computer could.

  5. The Datapoint 2200 • The Datapoint 2200 had a built-in full travel keyboard, a built-in 12 line, 80 column green screen monitor and two cassette tape drives each with 130 kb capacity. Its size and shape approximated that of an IBM Selectric typewriter. It shipped with 2 kb of serial shift register main memory. It’s starting price was around US $5000.

  6. The most popular PC • The Macintosh computer was released in January of 1984, with 128 kb RAM of memory. It quickly became obvious that this was insufficient, so eight months later Apple released an updated version, un-officially referred to as the 'Fat Mac'. It has 512 kb RAM, four times as much.

  7. Except for the very expensive and unpopular Apple Lisa which came out in 1983, the Macintosh is considered to be the first commercially successful computer to use a GUI (Graphical User Interface).

  8. Before the Macintosh, all computers were 'text-based' - you operated them by typing words onto the keyboard. The Macintosh is run by activating pictures (icons) on the screen with a small hand-operated device called a "mouse". Most modern-day computers now operate on this principle, including modern Apple computers and most others which run the Microsoft Windows operating system.

  9. The beginning of the Internet • The Internet is a worldwide system of computers and servers, joined together through telephone lines. It started in the 1960’s when the USA army wanted to protect their computers system from attack. With the Internet, information could go from one computer to another even one part of the system wasn’t working. In the 1970’s other computers were joined up and now anyone can join it.

  10. Did the Internet make our life easier and more interesting?

  11. The Internet is an international network of computers & servers – it includes electronic mail (e-mail), the World Wide Web (WWW), discussion groups and online chatting. • To go online you need a browser such as Safari or Mozilla Firefox. This programs let you see web pages and download information onto your computer. • Surfing the Net you can find any information for your work and studies, about entertainment or travel. • You can listen to and download music. • You can chat online. • You can send e-mails • You can shop different things • You can read about your interests • You can practice your English

  12. Arguments in favour of computers • Computers have changed our life. They help people to live at the faster pace modern living demands. It is worth mentioning a few examples. • Computers allow business people to keep in touch with developments all over the world. • They enable doctors to diagnose illnesses more accurately. • They let thousands of aircrafts fly safely through our crowded sky without bumping into other planes. • Computers can do accounting procedures more quickly and more accurately then people. • They find the right information, store it and do calculating. • In fact it is difficult to imagine any area of life where computers do not play an important role.

  13. Arguments against computers • But people use computers not only for work. Nowadays they often become a computer addict since their childhood. They can’t get rid of this bad habit even they are grown-ups. • Teenagers can’t stay away from the computer. Sometimes they play for about 24 hours a day. The video games are very addictive. • Playing computer games stops children from doing sports, they don’t have time for their friends. Their schoolwork also suffers because they do their homework as quickly as possible. • Video games make people antisocial. Many of the games are very violent, they can make teenagers aggressive. • The main problem with games is that they are too much fun. Lots of young people play them and if they are not careful, they can take over their lives.

  15. Have you got a computer? 100%

  17. What do you use the Net for? 40% 40% 5% 15%

  18. Do you play computer games? 25% 75%

  19. How much time do you spend with your computer? 20% 32% 48%

  21. Survey results: Though teens realize that sitting in front of computers for a long time does a lot of harm to their health and study, they spend many hours playing computer games or surfing the Net for pleasure.

  22. Conclusion

  23. Can we predict how computers will affect our future lives?Experts foresee that:

  24. Next decade we can have miniature computers inside us to monitor and regulate our blood pressure, heart rate and cholesterol. Within twenty years we’ll have implanted chips that can correct our ability to interact with the world. • In fifty years shoppers will be able to scan down virtual supermarket shelves all over the world on their PCs and click on whatever they want. They will be able to pay in their local currency through the Net. With this development, coins and notes are likely to disappear.

  25. But will computers rule the world? Will they be able to become more powerful than their creators?

  26. We think they won’t, because computers can only do what we ask them to do. We can get them to complete increasingly complicated operations, but contrary to the science-fiction nightmare, computers can never make us do anything.
