2. What is a technological revolution? Historical period when dramatic socioeconomic change results from a technological evolution.

3. What is a technological revolution? Historical period when dramatic socioeconomic change results from a technological evolution.  The Printing Press  Gutenberg, c. 1650 Started the Information Revolution

4. What is a technological revolution? Historical period when dramatic socioeconomic change results from a technological evolution.  The Spinning Jenny  Patented 1770 by James Hargreaves Started the Industrial Revolution

5. The Computer: a Modern Technological Revolution? Is it too early to declare this invention revolutionary?  The computer  Z1—Boolean logic; 1938  Colossus—WWII decryption

6. Effects of Computing The Apollo astronauts carried slide rules to space The Apollo computer had only 72KB of ROM Can you name some example of how faster, massive computation abilities have affected the progress of science and technology since the 1950’s?

7. The Internet: a Modern Technological Revolution? Is it too early to declare this invention revolutionary?  The internet  ARPANET—1969  TCP/IP—1974

8. Effects of Internet As of June 2014, only 42.3% of the world actually uses the internet. (87% in North America, 26% in Africa)  And yet, it affects:  Business practices, Information availability, Privacy,  Communication, Socialization, Media Can you name another medium that makes instant information, instant long-distance communication, and instant massive audience available to “the common man”?

9. Wireless Revolution? Are smartphones and wireless technologies a technological revolution? How are Smartphones different from computers, internet?

10. The Wireless Revolution A synergistic convergence of revolution s in:  Bandwidth  Cloud computing  Apps  Social networking  Size  Battery life  Computing efficiency  Screen Result: MOBILITY Why is mobility significant?

11. Bandwidth Current advancement: 10s of megabits per second Almost free Whenever, wherever Significance:  Allows for off-phone computation and storage, via apps and cloud computing  Social networking (aka, more business opportunities)
