Computer directly, and if this is a mathematical calculation. In other words, the power of using materials science and mathematics in order to facilitate easy to create a unique type of machine. Records Storage (Data Storage) Call (Retrieve), Programs insertion and extraction (l / O Device), Calculated considering (Calculate) are planned to be used by processes. The inventor of the computer was starting to think the business has developed is designed to be used at each stop. And computers were invented during the time (analog) (digital computer) There are two types of structure. (Analog computer) is based on the amount of power availability by showing approximate. Depending on the availability of precise Electric Power (Digital Computer). Before the computer era in the late 16th century onwards, various industry experts to facilitate convenience based on the [] (abacus) were developed step-by-step test. In 1614 (John Napier) looked ready mathematical calculations technical .5 up to five decimal places to calculate the exact solution generated Created invented Program (Logarithms). In 1615 William Oughtred invented (Slide Rule) from the system. (Slide Rule) means, in order to quickly calculate (Logarithms) system scheduled to brief mathematics of technological resources. Modern electronics today it has been used in the mathematical calculation (Electronic Calculator). In 1623 William Schickard mathematical calculation of the machine was invented (Mechanical Calculator). The first computing device program, France's son, Professor of mathematics and philosophy from Blaise Pascal invented in 1642 and was launched in 1645. For the device to perform a job, driving a gear (gear) (Pulley) structure. In 1672-1674 Gottfried Leibniz to have been invented in the first (Calculator). In 1801 with the efforts of Joseph Marie Jacquard, which is one that can operate automatically loom obtained (Analytical Engine). The device includes many hole cards (Punched-Card) input. Charles Thomas de Colmar in 1820 to enhance the first comprehensive calculation. In 1822, England's Charles Babbage a laboratory machine (Analytical Engine) planned for them and do not have any added include any calculations. However, the device is required in order to build the structure from many experts in this period were in difficulty. Charles Babbage's original idea, the machine is able to receive numerous data May be added, In order to answer. In the early 20th century by the use of a light bulb (Vacuum Tube) computer industrial electronic transition. Gear (Gear), and there have been no need for the device (Pulley). Electrical switches are able to get the same results. The two symbols (binary) has been used. Information and instructions (l / O) are summarized. The system (0) and (1) Numbers are enabled, Off (On / Off) allows operation at 0 to shrink more. (Vacuum Tube) gear (gear) and are more accurate than the machine (Pulley) work can be done. Think of Charles Babbage (Analytical Engine) that had been created in 1830 before the final. Finally, considering its all being used today were arriving into (Programmable Computer). In 1890 Herman Hollerith US Census records in the card Piercing System (punched-Card System) has been increased. In 1936, Alan Turing designed to enhance the computer's mathematical theory of technical. 1938 Konrad Zuse (Boolean) the letters using a mathematical system was built as the first (Binary Caculator). The first physics [math] and [1939] Studies have been used mainly by the Electric Power to work with mechanical calculations (J V Atanasoff-Barry) computer was invented in America. The device is the first combination lamps have been built to create and use. The mapping device exists. However, very long mathematical calculation of the technical chart each was designed to calculate approximate.
