1. The Personal Computer

2. Arguably, nothing in the 20 th Century has changed our lives more than Personal Computing. Take a few minutes and think about the ways in which the PC has affected society  Banking  Business  Education  Government  Police  Recreation In fact, it is hard to think of an unaffected area.

3. Timeline 1939- CNC (Complex Number Calculator) 1941- Konrad Zuse's Z3 computer 1941-1960- Computers get larger as they get more complex 1960- More than 2000 computers in the USA At this time computers were mostly being used for government and military purposes

5. Alan Turing

6. Turing was a British logician, mathematician, cryptanalyst, and computer scientist. He worked with programmable computers Responsible for the “blank-slate” design of modern computers He also worked with early artificial intelligence theory Creator of the “Turing Test” designed to tell the difference between humans and computers

7. Integrated Circuit

8. The Integrated Circuit A.K.A.: Microchip (First developed 1958) A “game-changer” Enabled computers to be much smaller, yet have more computational power Companies such as H.P. & IBM immediately saw the potential for the mass market Software programers did as well. (1958- First video game: “Tennis for Two”)

9. The PC's Origins By 1970, H.P. Had produced a computer that could fit on a desk 1973- Xerox Alto: PC with a GUI 1976- Steve Jobs & Steve Wozniak create the Apple I circuit board Expensive “Personal Computers” were being produced for businesses and organizations Less powerful “Home Computers” were being produced for recreation and home use By the early 1980's there was no difference between Personal and Home computers.

10. Microchips have continued to get smaller over the past 30 years. The smaller the chip, the smaller the device Now we have smart-phones, tablets, netbooks, and so-on. These devices are incredibly powerful compared to PCs from the 1980s. “I think it is fair to say that personal computers have become the most empowering tool we'ver ever created. They're tools of communication, they're tools of creativity, and they can be shaped by the user.” -Bill Gates, 2004

11. What do you think the future holds for “personal computing?”
