COMPUTERS….
• Have you ever thought how computers were first made or who made them and how? Well ,I have and we have all learned about it in computers 1 and 2 and it was quite cool. Do you know how your computer is made? Do you know who made it?
FACTS
• Early computational devices
• Early computers• Generations and m
ain components• Inventors/develope
rs• Internet• Wrap Up!• Citations
EARLY COMPUTATIONAL DEVICES
• First calculating tool was the abacus.
• Herman Hollerith developed a mechanical tabulator based on punched cards.
EARLY COMPUTERS
• Eckert and Mauchly both developed the first general purpose computer ENIAC and first commercial computer UNIVAC.
• Charles Babbage made the first computer.• Mark 1 was the first electronic computer made.
EARLY COMPUTERS CONT.
• Altair 8800 was the first microcomputer made in 1975.
• EDSAC and EDVAC are a couple of the earliest computers developed.
GENERATIONS AND MAIN COMPONENTS
• First generation was made up of vacuum tubes in 1946-1958. UNIVAC and ENIAC.
• Second generation computers were made up of transistors in 1956-1963.
• Third generation computers were made up of integrated circuits in 1965-1970. Can carry out instructions in billionths of a second.
GENERATIONS AND MAIN COMPONENTS CONT.
• Fourth generation computers were microprocessors made in 1971-today. Altair 8800 was the first microprocessor kit bought.
• Fifth generation computers are artificial intelligence. Made today-future. Quantum and Molecular will change in computers in years.
• Generations of Computers flyer.
INVENTORS/DEVELOPERS
• Steven Jobs and Steven Wozniak both helped create Apple.
• Bill Gates and Paul Allen helped design Microsoft.• In 1991, Tim Berners-Lee developed the World
Wide Web.
INVENTORS/DEVELOPERS CONT.
• Blaise Pascal made the first digital calculator.
• MANIAC was later developed by John Von Neumann.
INTERNET
• Birth of the net took place in 1969.
• ARPANET was the first Internet up and running and developed by Department of Defense.
• The first web browser made was Mosaic which was developed by Marc Andreesen.
WRAP UP!
• Well have you learned anything new about your computer? I have. Pretty fascinating how quickly our society has become more technological. Newer world means newer discoveries I guess. Can’t wait to see what our world will come up with next.
