THE INVENTIONS THAT CHANGED THE WORLD Simferopol College of National University of the Food Technologies
Introduction The invention of the digital computer transformed our civilization during the past 60 years and had profound social, economic and scientific effects. Still humans are just beginning to use the potential of computers. Our future progress will strongly depend on the development of computing technologies, it is important to clearly see the their possibilities. The development of computing technologies depends primarily on the general technological level, available production methods and the market demand for computing.
Computer History: Earliest computing machines Image 1 – Traditional abacus. Image 2 – The Suan Pan - Chinese abacus. The Abacus - is a calculating tool used primarily for performing arithmetic processes. Abacus is a beginning of development of computer technologies .
Computer History: Earliest computing machines Image 3 – The slide rule. The Slide Rule - is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for functions such as roots, logarithms and trigonometry.
Computer History: Earliest computing machines Image 4 – “Pascaline”. Pascal's Calculator or "Pascaline". This calculating machine could add and subtract two numbers directly and multiply and divide by repetition.
Computer History: Punched card technology Image 5 – punched card. A punched card (punch card, IBM card, or Hollerith card) is a piece of stiff paper that contains digital information represented by the presence or absence of holes in predefined positions.
Computer History: Punched card technology Image 6 – Analytical machines. The Analytical Engine was a proposed mechanical general-purpose computer designed by English mathematician Charles Babbage.
Computer History: Early electronic digital computation Image 7 – An artistic representation of a Turing machine. A Turing machine is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.
Computer History: Early electronic digital computation Image 8 – Konrad Zuse and his Z3. The Z3 was an electromechanical computer designed by Konrad Zuse. It was the world's first working programmable, fully automatic digital computer.
Computer History: Early electronic digital computation Image 9 – ENIAC. ENIAC was the first electronic general-purpose computer. He was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.
Computer History: Early electronic digital computation Image 10 – SSEM “Baby”. The Manchester Small-Scale Experimental Machine (SSEM), nicknamed Baby, was the world's first stored-program computer. He ran its first program on 21 June 1948.
Computer History: First-generation computers Image 11 – EDSAC. First-generation computers (1937-1955) - is computers that used vacuum tubes as switching elements. Image 12 – EDVAC.
Computer History: Second-generation computers Image 13 – IBM 1401. Second-generation computers (1954-1962) - is computers that used transistors. Transistor was invented in 1947. By 1965 second-generation computers were used by many large companies. Image 14 – IBM 7030 Stretch.
Computer History: Third-generation computers Image 15 – IBM System/360 Model 30. 3rd generation of computers (1964-1973) was based on the integrated circuit (computer chip), developed in 1958. First computers of the new generation became available in 1965. Image 16 – IBM System/360 Model 65.
Computer History: Fourth-generation computers Image 17 – Scelbi microcomputer. 4th generation of computers, based on a microprocessor, appeared in 1972, just one year after the first microprocessor was created. Image 18 – Mark-8.
“The real danger is not that computers will begin to think like men, but that men will begin to think like computers.” - Harris, Sidney J.
