  1. History of Computers March 26, 2012 Greer Potadle

  2. Have you ever wondered how modern computers came about? • Today I will go over all of the most major advances and improvements of computers.

  3. Main Topics • Early Computational Devices • Early Computers • Generations and Main Components • Inventors/ Developers • Internet

  4. Early Computational Devices • Abacus • First recorded computational machine • Created in 300 B.C. • Babylonians created it • Used to count

  5. Early Computational Devices • EDSAC • Electronic Delay Storage Automatic Calculator • Used paper tape for input • Sent outputs to a tele-printer • First thinking machine • Created in 1949 at Cambridge University, England

  6. Early Computers • UNIVAC • First commercially available computer • Created in 1951 by Eckert and Mauchly • Separated problems of input and output from computation facility • Punched Cards • How you inputed and got output information • Created in 1970 by Herman Hollerith

  7. Early Computers • Mark 1 • Used pre-punched paper tape • Invented by Howard Aiken and Grace Hopper • In 1944

  8. Early Computers • First Microcomputer • Altair 8800 • Created by Ed Roberts in 1975 • Purchased for $439

  9. Early Computers • ENIAC • First General Purpose Computer • Created in 1946 • EDVAC • Electronic Discrete Variable Automatic Computer • First multipurpose computer • Most internal memory • Created in 1947

  10. Generations and Main Components • First Generation • Vacuum tubes were added to promote circuitry for memory • Second Generation • Transistors made them faster, cheaper, smaller, energy efficient • Third Generation • Integrated circuits increased speed

  11. Generations and Main Components • Fourth Generation • Fir Microprocessor was added • Fifth Generation • Artificial intelligence for computers to understand our language • For More Information on the Generations of Computers

  12. Inventors/ Developers • Charles Babbage • Considered father of computing • Created analytical machine in 1835 • Created a difference machine 1846-1859

  13. Inventors / Developers • Department of Defense • Created Arpanet in 1969 • Used for scientists to share ideas • Used for military leaders to communicate

  14. Inventors / Developers • Blaise Pascal • First digital calculator • In Texas, 1645 • Made to help his father with taxes

  15. Inventors / Developers • John Von Newman • Created the idea of storing programs as other data • They were performed sequentially

  16. Inventors / Developers • Steve Jobs and Steve Wozniak • Created Apple Inc. in 1976 • Started with the Macintosh • Bill Gates and Paul Allen • Founded Microsoft in 1975 • Created Basic language for software • Altair 8800

  17. Internet • Birth of the Net • Started in 1969 • Made as communication that was immune to nuclear attacks • During the cold war • Used by military leaders

  18. Internet • Tim Berners-Lee • Created World Wide Web (WWW) • In 1991 • Marc Andreessen • Created Mosaic • First Graphical Browser • 1992

  19. Works Cited • “Blaise Pascal (1623-1662).” Oregon State University. Oregon State University. 15 January 2011. 2 April 2012 <http://oregonstate.edu/instruct/phl302/philosophers/pascal.html>. • “History of the UNIVAC Computer.” About.com Inventors. 2012. 2 April 2012 <http://inventors.about.com/od/uvstartinventions/a/UNIVAC.htm>.

  20. The End • Now you have learned about the most historical events of the computer. I hope you enjoyed it! 
