Discussion Questions

1. This chapter lists a many ways in which knowing about computers (or becoming computer literate) will help you. How much do you know about computers? What else would you like to know? How do you think learning more about computers will help you in the future?
2. This chapter briefly discusses data mining, a technique companies use to study sales data and gather information from it. Have you heard of data mining before? How might companies like Wal-Mart or Target use data mining to better run their business? Can you think of any privacy risks data mining might pose?
3. Affective computing is the science that attempts to produce machines that understand and can respond to human emotions and social mores. Do you think humans will ever create a machine that cannot be distinguished from a human being? In your opinion, what are the ethical and moral implications associated with that development?
4. How might access to (or denial of) electronic information improve the education of a country's citizens? Could that affect who the world's next technology power will be? Could it eliminate third world status?

1. Can you think of any situations in which computers actually decrease productivity? Why? Should we always expect computers to increase our productivity? What do you think the impact of using computers would be:
   1. in a third-grade classroom?
   2. in a manager's office for a large chain supermarket?
   3. for a retired couple who purchases their first computer?
2. The Smart Medical Home project of the University of Rochester's Center for Future Health is researching how to use technology to monitor many aspects of your health. The Smart Medical Home is the creation of a cross-disciplinary group of scientists and engineers from the college, the Medical Center, and the university's Center for Future Health. This particular "smart home" includes a sophisticated computer system that helps keep track of items such as eyeglasses or keys, and the kitchen is equipped with a new kind of packaging to signal the presence of dangerous bacteria in food. Spaces between ordinary walls are stuffed with gadgetry, including banks of powerful computers.
   1. What abilities should a smart home have to safeguard and improve the quality of your life?
   2. Could there be potential hazards of a smart home?
3. When do you think a toy becomes a computer? The Microsoft Xbox 360 has a hard disk drive, a processor with three cores, internal RAM, and wireless capability. Apple iPods also have hard drives (or flash memory and a processor). Are these devices computers or toys? What capabilities do you think the next generation gaming consoles and iPods should have?
