While a computer can, in theory, be made out of almost anything (see misconceptions section), and mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs). Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space. Simple computers are small enough to fit into mobile devices , and can be powered by a small battery. Personal computers in their various forms are

This machine grew from the 'Manchester Baby', which in 1948 first demonstrated the now-standard technique of storing both data and programming instructions digitally. In 1948 an innovative memory device, a storage system now known as the Williams-Kilburn Tube, allowed the first electronic digital stored-program computer to be built in Manchester. To understand the development of the information age, historians also need a storage system. Computing machines became central to technological and social change in the twentieth century; their use determines many aspects of our lives in the twenty-first. British institutions and individuals played an important role in this process. However, the records and artefacts which might help the historian to document it are fast disappearing. The UK National Archive for the History of Computing (NAHC) was created in 1987 as a repository for the documents and images of computer history, and a centre to encourage its study. A rich collection is now available to scholars.

Computer Science Lab An Illustrated History of Computers Part 1 The first computers were people! That is, electronic computers (and the earlier mechanical computers) were given this name because they performed the work that had previously been assigned to people. "Computer" was originally a job title: it was used to describe those human beings (predominantly women) whose job it was to perform the repetitive calculations required to compute such things as navigational tables, tide charts, and planetary positions for astronomical almanacs. Imagine you had a job where hour after hour, day after day, you were to do nothing but compute multiplications. Boredom would quickly set in, leading to carelessness, leading to mistakes. And even on your best days you wouldn't be producing answers very fast. Therefore, inventors have been searching for hundreds of years for a way to mechanize (that is, find a mechanism that can perform) this task. This picture shows what were known as "counting tables" [photo courtesy IBM]

First Computers ENIAC Computer The first substantial computer was the giant ENIAC machine by John W. Mauchly and J. Presper Eckert at the University of Pennsylvania. ENIAC (Electrical Numerical Integrator and Calculator) used a word of 10 decimal digits instead of binary ones like previous automated calculators/computers. ENIAC was also the first machine to use more than 2,000 vacuum tubes, using nearly 18,000 vacuum tubes. Storage of all those vacuum tubes and the machinery required to keep them cool took up over 167 square meters (1800 square feet) of floor space. Nonetheless, it had punched-card input and output and arithmetically had 1 multiplier, 1 divider-square rooter, and 20 adders employing decimal "ring counters," which served as adders and also as quick-access (0.0002 seconds) read-write register storage. Progression of Hardware In the 1950's two devices would be invented that would improve the computer field and set in motion the beginning of the computer revolution. The first of these two devices was the transistor. Invented in 1947 by William Shockley, John Bardeen, and Walter Brattain of Bell Labs, the transistor was fated to oust the days of vacuum tubes in computers, radios, and other electronics.

History of computing hardware From Wikipedia, the free encyclopedia Jump to: navigation search Computing hardware is a platform for information processing block diagram The history of computing hardware is the record of the constant drive to make computer hardware faster, cheaper, and capable of storing more data. Before the development of the general-purpose computer, most calculations were done by humans. Tools to help humans calculate were then called "calculating machines", by proprietary names, or even as they are now, calculators . It was those humans who used the machines who were then called computers; there are pictures of enormous rooms filled with desks at which computers (often young women) used their machines to jointly perform calculations, as for instance, aerodynamic ones required for in aircraft design. Calculators have continued to develop, but computers add the critical element of conditional response and larger memory, allowing automation of both numerical calculation and in general, automation of many symbol-manipulation tasks. Computer technology has undergone profound changes every decade since the 1940s. Computing hardware has become a platform for uses other than mere computation, such as process automation, electronic communications, equipment control, entertainment, education, etc. Each field in turn has imposed its own requirements on the hardware, which has evolved in response to those requirements, such as the role of the

Konrad Zuse (1910-1995) At the beginning of WW2 in Berlin, Germany, Konrad Zuse was a construction engineer for the Henschel Aircraft Company who built a series of automatic calculators to assist him in his engineering work. Zuse's inventions have earned the title of being "The Inventor Of The Modern Computer." Zuse modestly dismissed the title, while praising many of the inventions of his contemporaries and successors, as being equally, if not more important than his. Zuse learned that one of the most difficult aspects of doing a large calculation is keeping track of all intermediate results and using them, in their proper place, in later steps of the calculation, Zuse realized that an automatic-calculator device would require three basic elements a memory, a control, and a calculator for the arithmetic.

History Of Computers Does the history of computers , those wonderful, information rich tools that bring the world to our fingers and sometimes aggravation to our lives have any interest to us? It probably ought to because the computer has been voted one of the most influential inventions of the last one hundred years, although this writer's choice is the air conditioner which has sucked everybody back in our cool houses and away from relationships that were born on front porches during long summer evening walks. No, this is not about air conditioners. While the abacus has been around for tens of centuries, anything resembling what might be called a computer of sorts was invented in the late 1930's and early 40's by a German inventor named Konrad Zuse. The man has been called the father of the modern computer. By the seventies, internal parts of a computer began acquiring names with which many Americans are now familiar. Hard drives, disk drives, motherboard, sound card, power supply, CPU and other terms started being uttered on the lips of a few and later became the common vocabulary of millions. Americans may not have understood what any of these parts played in the pc processing scheme, but they knew that a hard disk breakdown or a motherboard being fried was not a good thing. Many a pc was tossed out a nearby window when the term fatal error flashed on the screen. And when a disk drive went bad, many Americans began to understand that the problem was just a matter of slipping one out and putting another one in its place. "I beseech you therefore brethren by the mercies of God that ye present your bodies a living sacrifice, holy, acceptable unto God which is your reasonable service." (Romans 12:1)

19. A Brief History Of Computers And Networks From the early proposals, through World War II, and into the computer age, this history tracks the development of modern computing http://goldenink.com/computersandnetworks.shtml

A Brief History of Computers and Networks, Part I Webster's Dictionary defines "computer" as any programmable electronic device that can store, retrieve, and process data. The basic idea of computing develops in the 1200's when a Moslem cleric proposes solving problems with a series of written procedures. As early as the 1640's mechanical calculators are manufactured for sale. Records exist of earlier machines, but Blaise Pascal invents the first commercial calculator, a hand powered adding machine. Although attempts to multiply mechanically were made by Gottfried Liebnitz in the 1670s the first true multiplying calculator appears in Germany shortly before the American Revolution. In 1801 a Frenchman, Joseph-Marie Jacquard builds a loom that weaves by reading punched holes stored on small sheets of hardwood. These plates are then inserted into the loom which reads (retrieves) the pattern and creates(process) the weave. Powered by water, this "machine" came 140 years before the development of the modern computer. Ada Lovelace Shortly after the first mass-produced calculator(1820), Charles Babbage begins his lifelong quest for a programmable machine. Although Babbage was a poor communicator and record-keeper, his difference engine is sufficiently developed by 1842 that Ada Lovelace uses it to mechanically translate a short written work. She is generally regarded as the first programmer. Twelve years later George Boole, while professor of Mathematics at Cork University, writes An Investigation of the Laws of Thought(1854), and is generally recognized as the father of computer science.

Articles and Resources The History of the Computer bone carved with prime numbers found in 8,500 BC. The abacus In 19 th century England, Charles Babbage , a mathematician, proposed the construction of a machine that he called the Babbage Difference Engine. It would not only calculate numbers, it would also be capable of printing mathematical tables. The Computer History Museum Ada Byron Lovelace The computers that followed built on each previous success and improved it. In 1943, the first programmable computer Turing COLOSSUS appeared. It was pressed into service to decipher World War II coded messages from Germany. ENIAC , the brain, was the first electronic computer, in 1946. In 1951, the U.S. Census Bureau became the first government agency to buy a computer, UNIVAC The Apple expanded the use of computers to consumers in 1977. The IBM PC for consumers followed closely in 1981, although IBM mainframes were in use by government and corporations. 8,500 BC Bone carved with prime numbers found 1000 BC to 500 BC Abacus invented invented adding machine, France
