Brief History of Computers (A Look Back at Computing) Computers have become one of the most important parts of modern society. Nearly everything that is modern required or uses computer related technology in some way. But how did computers as we know them come to exist? Did someone sitting in his lab just one day say‚ "Aha! I’ve got it! The computer?! Well‚ no‚ that is not how this happened. Rather‚ many years of brilliant ideas and research from many different individuals contributed

Would you use this web page when writing a term paper about the history of computers? A Brief History of Computer Technology A complete history of computing would include a multitude of diverse devices such as the ancient Chinese abacus‚ the Jacquard loom (1805) and Charles Babbage’s ``analytical engine’’ (1834). It would also include discussion of mechanical‚ analog and digital computing architectures. As late as the 1960s‚ mechanical devices‚ such as the Marchant calculator‚ still found

From the invention of the simple calculator to the Internet‚ technology has been a great factor on the way our civilization has grown. With more and more technological advances just around the corner‚ our civilization will continue to grow faster and faster than ever before. After the invention of the computer this world did many inventions in a short time with the help of technology

vacuum tubes was the ENIAC conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania which consisted of eighteen thousand tubes[B1]‚ seven thousand two hundred crystal diods‚ seventy thousand resistors ten thousand capasitors and five million hand soldered points. [pic]Pic.1 The trouble with the ENIAC was that it took up lots of room‚ 1800 square feet to be exact. Another problem with the machine was power consumption. It was said that the ENIAC would cause rolling

slide rules by William Oughtred were significant events in the evolution of computers. Evolution of computer technology can be divided into five generations. First generation computer consisted of vacuum tubes and they were used from 1943-1958. ENIAC (Electronic Numerical Integrator and Calculator) computer is an example of first generation computer. Second generation (1959-1965) computer consisted of transistors i.e. vacuum tubes were replaced by transistors. Thus the size of the computer got

History of Computer Introduction Man’s progress is measured by sophistication of his tools. First‚ he discovered how to control fire. Eventually‚ he invented the wheel. He built boats and earned to harness the wind. As soon as commerce developed in the early societies‚ people recognized the need to calculate and keep track of information. They soon devised simple computing devices and bookkeeping systems to enable them to add‚ subtract‚ and simple record transactions. Today‚ we are witnessing

of operations saved and retrieved. The first modern computer was invented during World War II. It was invented by a team of scientist and engineers at the University of Pennsylvania. It was actually a general purpose digital calculator called the ENIAC. The computer first started with a machine that could calculate math problems known as a calculator to us today‚ but known as the difference engine to Charles Babbage in 1833. The main purpose of the machine was to calculate astronomical tables. The

"The society in which we live in has been so profoundly affected by computers that historians refer to the present time as the information age." (Presley‚ 16) Comments like this show how computers have changed how we live‚ work‚ and play. For example‚ combined with the Internet‚ computers have incorporated many forms of communications into a universal one. The computer’s role in the world continues to grow in importance even as we sometimes take it for granted. We must realize how greatly computers

energy‚ and they generated much heat. # Unfortunately‚ a tube failure occurred average once every 7 minutes. Since it took more than 15 minutes to find and replace the faulty tube‚ it was difficult to get any useful computing work done. Moreover‚ the ENIAC was enormous‚ occupying 1500 square feet and weighing 30 tons. # The computers memory was stored on magnetic storage devices‚ primarily magnetic tapes and magnetic drums. Most of the data were entered into the computers on punched cards similar to
