2. History of Computer Wyatt Feiling

3. Did you know... The first idea for a computer was in the early 1800s Charles Babbage is the man who is credited with this idea.

4. Important Parts of Computer History Early Computational Devices Early Computers Generations & Main Component Inventors/Developers Internet

5. Early Computational Devices Abacus Punched Cards

6. Abacus Early aid for mathematical computations. Measures the speed of a computer

7. Punched Cards Early form of input devices. Enabled computers to do tasks.

8. Early Computers ENIAC Mark1 EDSAC EDVAC UNIVAC

9. ENIAC (Electronic Numerical Integrator And Computer) The first general use computer.

10. Mark1 Electro-mechanical computer Used for storage

11. EDSAC (Electronic Delay Storage Automatic Calculator) Second practical stored-program electronic computer.

12. EDVAC (Electronic Discrete Variable Automatic Computer) One of the earliest computers.

13. UNIVAC (Universal Automatic Computer) First commercial computer produced in US.

14. Generations of Computers First Generation Second Generation Third Generation Fourth Generation Fifth Generation Generation Worksheet

15. First Generation Vacuum tubes were used for circuitry. Magnetic drums were used for memory. The size of the early computers took up an entire room

16. Second Generation Transistors replaced vacuum tubes. Were now smaller, faster, and more efficient.

17. Third Generation Semiconductors replaced transistors. Computers now increased in speed and efficiency. Devices could run multiple apps at a time.

18. Fourth Generation Currently used Integrated circuits were equipped within a single chip. Instead of an entire room, it can now fit in someone’s hand.

19. Fifth Generation Still in development Will use parallel processing and superconductors to create artificial intelligence. These new devices will be capable of learning.

20. Inventors/Developers Steven Jobs & Steven Wozniak Bill Gates & Paul Allen Charles Babbage Herman Hollerith Blaise Pascal John Von Neumann Presper Eckerty & John Mauchly

21. Steven Jobs & Steven Wozniak Creators of Apple Inc. Released first Apple computer (Apple I) on April 1, 1976 =

22. Bill Gates & Paul Allen Creators of Microsoft/Windows. First Microsoft computer (Windows 1.0) is announced November 20, 1985. =

23. Charles Babbage Father of Computing Originated the concept of a programmable computer.

24. Herman Hollerith The founder of IBM Created and used punched cards.

25. Blaise Pascal Famous mathematician & physician Created a machine that automatically adds and subtracts.

26. John Von Neumann Famous American mathematician that contributed to the development of computers. Developed a software written in binary code.

27. Presper Eckert & John Mauchly Created the first all electronic computer, the ENIAC Formed EMCC to build new computer designs for commercial and military applications.

28. Internet Birth of the Net Mosaic Browser Worldwide Web ARPANET

29. Birth of the Net Invented in 1969 Created a computer network that would continue to function in the event of a disaster.

30. Mosaic Browser World’s first web browser Created by Marc Andreesen =

31. Worldwide Web World’s first communicating system Created by Tim Berners-Lee =

32. ARPANET Later changed to the Internet Created by the Department of Defense.

33. All in All Without these people and the developments they contributed, we would not be any where near close to the computers we have now.
