    The first devices for calculations were probably the well-known counting sticks, which are still used today. primary school many schools for teaching counting. The first devices for calculations were probably the well-known counting sticks, which are still used today in the primary classes of many schools for teaching counting.

    When people got tired of counting by bending their fingers and moving sticks, they invented the abacus (abacus). When people got tired of counting by bending their fingers and moving sticks, they invented the abacus (abacus).

    The number of items counted corresponded to the number of dominoes of this instrument moved.

    In 1623, Wilhelm Schickard invented the "Counting Clock" - the first mechanical calculator that could perform four arithmetic operations. The device was called a counting clock because, like in a real clock, the operation of the mechanism was based on the use of sprockets and gears. Practical use This invention found its way into the hands of Schickard's friend, philosopher and astronomer Johannes Kepler.

    This was followed by machines by Blaise Pascal (Pascalina, 1642) and Gottfried Wilhelm Leibniz. Around 1820, he created the first successful, mass-produced mechanical calculator - the Thomas Adding Machine, which could add, subtract, multiply and divide. It was mainly based on the work of Leibniz. Mechanical calculators that counted decimal numbers were used until the 1970s, followed by machines by Blaise Pascal (Pascalina, 1642) and Gottfried Wilhelm Leibniz.

    In 1801, Joseph Marie Jacquard developed a loom in which the embroidered pattern was determined by punched cards. The series of cards could be replaced, and changing the pattern did not require changes in the mechanics of the machine. This was an important milestone in the history of programming.

    In 1890, the US Census Bureau used punch cards and sorting mechanisms developed by Herman Hollerith to process the decennial census data stream. In 1890, the US Census Bureau used punch cards and sorting mechanisms developed by Herman Hollerith to process the decennial census data stream.
    Hollerith's company eventually became the core of IBM. This corporation developed punched card technology into a powerful tool for business data processing and produced an extensive line of specialized data recording equipment. By 1950 IBM technology has become ubiquitous in industry and government. The warning printed on most cards, “do not fold, twist or tear,” became the motto of the post-war era.

    By 1900, early mechanical calculators cash registers and adding machines were redesigned using electric motors, representing the position of a variable as the position of a gear. Beginning in the 1930s, companies such as Friden, Marchant, and Monro began producing desktop mechanical calculators that could add, subtract, multiply, and divide. The word "computer" was a job title for people who used calculators to perform mathematical calculations.

    In 1939, John Vincent Atanasoff and Clifford Berry of Iowa State University developed the Atanasoff-Berry Computer (ABC). It was the world's first electronic digital computer. The design consisted of more than 300 vacuum tubes, and a rotating drum was used as memory. Although the ABC machine was not programmable, it was the first to use vacuum tubes in the adder.

    The American ENIAC, often called the first general-purpose electronic computer, publicly proved the applicability of electronics for large-scale computing. This became a key moment in the development of computing machines, primarily because of the enormous increase in computing speed, but also because of the possibilities for miniaturization that emerged. Created under the direction of John Mauchly and J. Presper Eckert, this machine was 1000 times faster than all other machines of the time. The development of ENIAC lasted from 1943 to 1945.

    In 1955, Maurice Wilkes invented microprogramming, a principle that was later widely used in the microprocessors of a wide variety of computers. Microprogramming allows you to define or extend basic set commands using built-in programs called firmware.

    The next major step in the history of computer technology was the invention of the transistor in 1947. They have become a replacement for fragile and energy-intensive lamps. Transistorized computers are usually referred to as the "second generation" that dominated the 1950s and early 1960s. Thanks to transistors and printed circuit boards, a significant reduction in size and energy consumption, as well as increased reliability, was achieved. However, second generation computers were still quite expensive and therefore were used only by universities, governments, and large corporations.

    The rapid growth in the use of computers began with the so-called. "3rd generation" of computers. This began with the invention of integrated circuits, which were independently invented by Nobel Prize winner Jack Kilby and Robert Noyce. This later led to the invention of the microprocessor by Tad Hoff (Intel). The rapid growth in the use of computers began with the so-called. "3rd generation" of computers.

    The advent of microprocessors led to the development of microcomputers, small, inexpensive computers that could be owned by small companies or individual people. Microcomputers, members of the fourth generation, first appeared in the 1970s, became ubiquitous in the 1980s and beyond. Steve Wozniak, one of the founders of Apple Computer, became known as the developer of the first mass home computer, and later - the first personal computer. Computers based on microcomputer architecture, with capabilities added from their larger cousins, now dominate most market segments.

    History of development An important event of the 19th century was the invention of the English mathematician Charles Babbage, who went down in history as the inventor of the first computer - the prototype of modern computers. By 1822, he had built a working model of a difference engine that executed a specific program, and calculated a table of squares on it. He could operate with 18-bit numbers

    Before the advent of the first personal computers, purchasing and using computers was very expensive. Few of them ordinary people I could afford to have such a miracle of technology at home! Computers were installed in large corporations, universities, research centers and government institutions. August 12, 1981 American company IBM Corporation (International Business Machines) introduced the first personal computer model, the IBM 5150, which marked the beginning of the era of modern computers.
