    1. CSE 101 Introduction to Computers and Information Technology A Brief History of Computing

    2. Everyone get ready to take notes I’m going to mention some names today I’m going to tell some stories today Be prepared to do a little research at home

    3. A start of semester quiz (for fun, not points) When was the first digital electronic computer invented? the first programming language invented? the Internet invented? the first personal computer available? NOTE in the history of computing, many times being the one who invents the “first so and so” is not as significant as being the one who invents the “first successful so and so” by successful I mean widely appreciated

    4. Computing Timeline

    5. Computing Timeline

    6. Who invented the computer? The Candidates: Zuse? (Z1-Z4) Flowers/Turing? (COLOSSUS) Atanasoff/Berry? (ABC Computer) Eckert/Mauchly? (ENIAC/EDVAC) Von Neumann? (EDVAC) Newman/Williams? (Manchester Baby) Wilkes? (EDSAC)

    7. History’s Impact on Computing WW II Cold War Space Race EU

    8. Computing Innovation Public Sector University research Defense department research Private Sector IBM Defense contractors The 7 Dwarves Nerd Culture

    9. Time-traveling Aliens have landed! Technologically advanced aliens read A Connecticut Yankee in King Arthur’s Court (audio version) and feel inspired, so just for fun they abduct you and transport you back to England in the year 528 A.D.

    10. What if you could take some help with you?

    11. My Guess? Even with help, humanity would be doomed Why would I guess that? lack of pre-computing technologies lack of resource gathering technologies lack of manufacturing technologies Timing is everything!

    12. Microsoft & IBM A tale of timing & bad decisions How is it “IBM PC clones” are 90% of the PC market (or more), and yet no one uses IBM PCs? How is it that Windows is almost 90% of the Operating Systems market?

    13. Apple vs. Microsoft Who had the GUI first? Neither Xerox took it from Douglas Engelbart of Stanford Apple took it from Xerox Microsoft took it from Apple

    14. Why is the Internet “free”? When I say “free” I mean you don’t go to the store and buy “Web 3.0” The Web is a community of shared technologies agreed upon by everyone Who invented the Web? Tim Berners-Lee Along with URL, HTTP, HTML It’s built on top of the Internet TCP/IP and many other technologies DNS Who manages the WWW? The World Wide Web Consortium (W3C)

    15. Why is IE 85% of the browser market? Netscape had the dominant position in the mid-late 1990s Netscape vs. Microsoft
