Introduction Have you ever wandered what the history of computers were?Well in this power point you will learn all about the history of computers.

Main Topics Things you will learn about are:Early Computational DevicesEarly ComputersGenerations & Main Components Inventors/ Developers Internet Early Computational Devices Some early computational devices are the Abacus and punch cards.The Abacus was the first external aid to computing math.Punch cards were paper that contained digital information represented by holes. Early ComputersENIAC- First general purpose electronic computer.Mark 1- First programmable digital computer made in the U.S.EDSAC- Second practical stored program computer. Early Computers Continued.EDVAC- One of the earliest electronic computers. UNIVAC- First commercial computer in U.S.First Microcomputer- Computer with a microprocessor as a CPU.

Generations & Main ComponentsFirst Generation- Vacuum Tubes 1940-1956Second- Transistors1956-1963Third Generation- Integrated Circuits1964- 1971Generations Continued. Fourth- Microprocessors 1971- PresentFifth- Artificial Intelligence Present & Beyond. Inventors/ DevelopersSteven Jobs- Co Founder of AppleSteven Wozniak- Co Founder of AppleBill Gates- Co Founder of MicrosoftPaul Allen- Co Founder of Microsoft

Inventors Continued. Tim Berners-Lee- Inventor of the World Wide Web. Marc Andreessen- Created Mosaic, & co founder of Netscape Communications Co.Charles Babbage- (Father of Computing)- Invented First Mechanical Computer. Inventors Continued. Herman Hollerith- Father of modern automatic computing, created punch cards.

Blaise Pascal- Invented one of the first mechanical calculations.

Inventors Continued. John Von Newman- Worked on the design for EDVAC

Eckert & Mauchly- Created Eckert & Mauchly Computer Corporation. Internet The birth of the net grew out of an experiment began by the Department of Defense in the 1960s. ARPANET- Core network of what came to be the Internet.

Internet Continued. The first internet browser was Mosaic, its clean and easy to understand user interface helped open up the Web to the public. Summary Now you have learned all about the history of computers.I hope you now know how computers came to be like the ones you use.
