Evolution of the Computer:
The first counting device was the abacus, originally from Asia. It worked on a place-value notion meaning that the place of a bead or rock on the apparatus determined how much it was worth.
1600s: John Napier discovers logarithms. Robert Bissaker invents the slide rule which will remain in popular use until 19??.
1642: Blaise Pascal, a French mathematician and philosopher, invents the first mechanical digital calculator using gears, called the Pascaline. Although this machine could perform addition and subtraction on whole numbers, it was too expensive and only Pascal himself could repare it.
1804: Joseph Marie Jacquard used punch cards to automate a weaving loom.
1812: Charles P. Babbage, the "father of the computer", discovered that many long calculations involved many similar, repeated operations. Therefore, he designed a machine, the difference engine which would be steam-powered, fully automatic and commanded by a fixed instruction program. In 1833, Babbage quit working on this machine to concentrate on the analytical engine.
1840s: Augusta Ada. "The first programmer" suggested that a binary system shouled be used for staorage rather than a decimal system.
1850s: George Boole developed Boolean logic which would later be used in the design of computer circuitry.
1890: Dr. Herman Hollerith introduced the first electromechanical, punched-card data-processing machine which was used to compile information for the 1890 U.S. census. Hollerith's tabulator became so successful that he started his own business to market it. His company would eventually become International Business Machines (IBM).
1906: The vacuum tube is invented by American physicist Lee De Forest.
1939: Dr. John V. Atanasoff and his assistant Clifford Berry build the first electronic digital computer. Their machine, the Atanasoff-Berry-Computer (ABC) provided the foundation for the advances in electronic digital computers.
1941, Konrad Zuse (recently deceased in January of 1996), from Germany, introduced the first programmable computer designed to solve complex engineering equations. This machine, called the Z3, was also the first to work on the binary system instead of the decimal system.
1943: British mathematician Alan Turing developped a hypothetical device, the Turing machine which would be designed to perform logical operation and could read and write. It would presage programmable computers. He also used vacuum technology to build British Colossus, a machine used to counteract the German code scrambling device, Enigma.
1944: Howard Aiken, in collaboration with engineers from IBM, constructed a large automatic digital sequence-controlled computer called the Harvard Mark I. This computer could handle all four arithmetic opreations, and had special built-in programs for logarithms and trigonometric functions.
1945: Dr. John von Neumann presented a paper outlining the stored-program concept.
1947: The giant ENIAC (Electrical Numerical Integrator and Calculator) machine was developped by John W. Mauchly and J. Presper Eckert, Jr. at the University of Pennsylvania. It used 18, 000 vacuums, punch-card input, weighed thirty tons and occupied a thirty-by-fifty-foot space. It wasn't programmable but was productive from 1946 to 1955 and was used to compute artillery firing tables. That same year, the transistor was invented by William Shockley, John Bardeen and Walter Brattain of Bell Labs. It would rid computers of vacuum tubes and radios.
1949: Maurice V. Wilkes built the EDSAC (Electronic Delay Storage Automatic Computer), the first stored-program computer. EDVAC (Electronic Discrete Variable Automatic Computer), the second stored-program computer was built by Mauchly, Eckert, and von Neumann. An Wang developped magnetic-core memory which Jay Forrester would reorganize to be more efficient.
1950: Turing built the ACE, considered by some to be the first programmable digital computer.

ENIAC is in a computer history milestone is original, computer's English original word “computer” is the human who refers to is engaged in the data computation. But they often need with the aid of certain machinery calculating device or the analog computer. These early time calculating device's ancestor includes the abacus, as well as may trace 87 B.C. An who uses in by the ancient Greece person calculating the planet migration Ti the base Tela mechanism. Along with the middle ages last stage Europe mathematics and engineering prosperous once more, in 1623 took the lead by Wilhelm Schickard to develop Europe first calculating device, this was one can carry on six within number plus-minus methods, and could “calculate the clock” through the ting output answer. The use transmission gear carries on the operation. 1642 year France mathematician Pascal in WILLIAM in the Oughtred calculating rule's foundation, improves the calculating rule, can carry on eight computations. Also has sold many products, became at that time one kind of fashionable commodity.
in 1801, Joseph Marie Jacquard has made the improvement to loom's design, he used a series of punch paper card to take the knitting complex design the procedure. Jacquard type loom, although was not considered that is a genuine computer, but its appearance is truly in the modern computer developing process important one step. Charles Babbidge (Charles Babbage) is devises and designs one completely programmable computer's first person, at that time was in 1820. But as a result of the engineering factor, the funds limit, as well as is unable to endure patiently to patching which designs does not stop, this computer has not been able to come out throughout in his rest of the year. Approximately to the 19th century later period, many were proven afterward that has the great significance technology to the computer science to appear one after another, including punched card as well as vacuum tube. Hermann Hollerith has designed the machine which a scheduling uses, has realized the application punched card large-scale automatic data processing.
In the first half of 20th century, to cater to the science computation the need, many special purposes and deepen the complex analog computer to develop unceasingly. These computers are the specific question machinery which or the electronic model aims at with them take the computation foundation. The 20th century 30-40 ages, computer's performance was formidable gradually, and the versatility obtained the promotion, the modern computer's essential characteristic is joined unceasingly. the 1937 year (Claude Shannon) has published his great paper by Chrowder · Aier Wood · Shannon "to Relay And In Switching circuit's Symbolic analysis", in the article mentions the digit electronic technology for the first time the application. He had demonstrated to the people how to use the switch to realize logic and mathematics operation. Hereafter, he through studied Vannevar Bush the differential simulator to further consolidate his idea. This is one symbolizes the binary system electronic circuit design and the logical gate application start significant instant, but takes the pioneer who these key ideas are born, must include: Almon Strowger, he was one includes the logical gate equipment to apply for the patent; Nicolay Tesla (Nikola Tesla), he as early as once applied in 1898 to include the logical gate electric circuit equipment; Lee De Forest, he used the vacuum tube in 1907 to replace the relay.
Commodore Corporation the Amiga 500 computers which produces in the 20th century the 80s endless long-distance defines so-called “the first electronic accounting machine” along this kind of high and low seeking quite to be difficult. on May 12, 1941, Konrad Zuse has completed his mechanical and electrical sharing equipment “Z3”, this is first has the automatic binary system mathematical computation characteristic as well as the feasible programming function computer, but is not “the electron” the computer. In addition, other are noteworthy the achievement which mainly to have: in 1941 was born in the summer the Atanasuofu - shell auspicious computer was in the world the first electronic accounting machine, it has used the vacuum tube calculator, the binary value, but multiplying memory; In Britain in 1943 the mystical great elephant computer which demonstrated (Colossus computer), although programming ability is extremely limited, but it indeed told the people to use the vacuum tube both to be worth trusting and can realize the electrification again programming; Harvard University's Harvard Mark I; As well as based on binary system “Egyptian Nepal Acher” (ENIAC,1944 year), this is the first general intention computer, but because its structural design insufficient elastification, causes to it each time to program again means the electricity physical circuit's again connection.
Developed the Egyptian Nepal Acre's group to further consummate the design in view of its flaw, and presented Feng · who finally we knew very well today the Nuoyiman structure (procedure memory architecture). This system possesses computer's foundation now. In the 1940s the mid and late stage, started based on this system's computer to develop in large numbers, by Britain most early. What although the first development completes and the be operated is “the small scale testing aircraft” (Small-Scale Experimental Machine, SSEM), but is developed practical machine very possible is EDSAC truly. in entire the 1950s, the vacuum tube computer resided in the dominant status. on September 12, 1958 in Robert Noyce (INTEL Corporation's founders) under the leadership, has invented the integrated circuit. Soon has promoted the microprocessor. from 1959 the computer which to 1964 designed is been called generally the second generation of computer.
To the 60s, the transistor computer has displaced it. The transistor volume is smaller, the speed is quicker, the price is more inexpensive, the performance is more reliable, this causes them to be possible by the commercialized production. 1964 to 1972 computer is called generally the third generation computer. The massive use integrated circuit, the typical type is the IBM360 series. to the 70s, the integrated circuit technology's introduction reduced the computer production cost enormously, the computer also henceforth started to move toward everyone. in after 1972 computer custom is called the fourth generation of computer. Based on large scale integrated circuit, and afterward ultra large scale integrated circuit. on April 1, 1972 INTEL promoted 8008 microprocessors. in 1976 Stephen Wozinak and Stephen Jobs origination apple computer company. And promotes its Apple I computer. in May, 1977 Apple II computer issue. on June 1, 1979 INTEL has issued 8 element 8088 microprocessors. the 1982 year, the microcomputer starts to popularize, enters the school and the family massively. in the January, 1982 Commodore 64 computers issued, price: 595 US dollars. in February, 1982 80286 issues. The clock rate enhances 20MHz, and increased the protected mode, may visit the 16M memory. Supports above 1GB the virtual memory. Each second carries out 2,700,000 instructions, integrated 134000 transistors.
in November, 1990: First generation of MPC (multimedia personal computing standards) issued. Processor 80286/12MHz, afterward increased at least to 80386SX/16 MHz, and light drives, at least 150 KB/sec transfer rates. on October 10, 1994 Intel issued 75 MHz the Pentium processor. on November 1, 1995 Pentium Pro issue. The basic frequency may reach 200 MHz, each second completes 440,000,000 instructions, integrated 5,500,000 transistors. on January 8, 1997 Intel issued Pentium MMX.

Acknowledged by the whole world's first electronic computer ENIAC, the birth place suffered in the Second World War, and its "birthplace" Abedin, Maryland, the United States Army field artillery test. The secret is that Abeiding test field artillery computer development from the initial idea of the "control theory" Father of Wiener (L. Wiener) Professor letter. As early as during the first World War, had come to Wiener Abeiding test field artillery. At that time, ballistics laboratory, the famous mathematician Huibailun (O. Veblen) asked him for the preparation of a range of antiaircraft artillery table. Here, he not only the initiation of the control theory, thinking, and first saw the need for a high-speed computers.
Over the years, Wiener and the invention of the computer simulation Bush has been working with the Massachusetts Institute of Technology, have forged profound friendship. 1940, in a letter to Bush, Wiener wrote, the modern computer is digital, electronic components constituted by using binary, and the internal storage of the data. Wiener made these principles, guidelines for the electronic computer in the right direction.
