1. The document outlines the history of important developments in computing, beginning with early numbering systems developed by Hindus between 100-200 CE and the Chinese abacus around 500 BCE. 2. Key figures that advanced computing include Charles Babbage, who invented the Difference Engine and Analytical Engine in the 1820s-1830s; Herman Hollerith, who developed the Census Tabulating Machine using punch cards in 1890; and J. Presper Eckert and John Mauchly, who created the ENIAC, the first general-purpose electronic computer, in 1946. 3. The document also describes the three generations of computers: first generation used vacuum tubes from 1951-1958; second generation used
History of computer
- 1. SEQUENCE ___ John Napier - logarithm ___ Blaise Pascal - Pascaline ___ Gottfried Leibnitz – Stepped reckoner ___ Herman Hollerith – Census Tabulating Machine ___ Hindus – numbering system ___ Eckert & Mauchly – ENIAC & UNIVAC ___ Charles Babbage – Difference Engine ___ Howard Aiken – Mark I ___ Chinese - Abacus Write the numbers on the blank to arrange the events in order 1 - 9. Copy and write your answer in ¼ sheet of paper.
- 2. Hindus of India -First numbering system 1 to 9 100 -200 CE (COMMON ERA) It is said that the first numbering system from 1 to 9 was invented.
- 3. Chinese - ABACUS (first adding machine) 500 BCE The first recorded adding machine was invented by Babylonian (now IRAQ) which is then popularized by the Chinese.
- 4. Logarithm - Jhon Napier - Father of logarithm (title) 1614 John Napier, the father of logarithm introduced the use of log in multiplication and division.
- 5. Blaise Pascal -PASCALINE ( rotating wheel calculator) 1642 It was then followed by the discovery of Pascaline, a french mathematician.
- 6. Gottfried Leibnitz - STEPPED RECKONER 1671 A german mathematician invented a machine that could multiply 5 – 12 digit numbers yielding up to 16 digit numbers.
- 7. Charles Babbage - Difference Engine - Father of Modern Computer (title) 1821 Invented a steam-powered adding machine. This is the first modern computer device that can automatically solve math problems. He later developed the use of punch cards and invented the analytical engine in order to solve and print complex mathematical operations in 1832.
- 8. Herman Hollerith - Census Tabulating Machine - Father of Information Processing (title) 1890 American commissioned by the US government working on census preparation, has successfully adopted the use of punch cards in
- 9. HOWARD AIKEN -MARK I – 1st stored program computer 1942 A mathematician of Harvard University invented the first stored program computer.
- 10. J.Presper Eckert Jr. & Jhon Mauchly - ENIAC & UNIVAC 1946 & 1951 Universal Automatic Calculator (UNIVAC The ENIAC: Electronic Numerical Integrator and Computer First electronic digital computer developed at the University of Pennsylvania
- 11. 1951 - 1958 1ST GENERATION COMPUTER Characterized by the use of vacuum tubes as the main logic element and have the ability to store 1,000 – 4,000 characters with speed of 200 instructions per second. ENIAC and UNIVAC is an example of this generation.
- 12. 1959 - 1963 2ND GENERATION COMPUTER Are made up of a small, solid-state component designed to monitor the flow of electric current called transistors. This allows computers to communicate over telephone lines and have the ability to store 4,000 to 320,000 characters and could process one million instructions per second.
- 13. 1964 - 1974 3RD GENERATION COMPUTER A new technology that uses a single chip that equates a number of transistors and electronic circuits.
