Our Reliance on Computers :: essays research papers fc
Ã¢â¬Å"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.Ã¢â¬ (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 computerÃ¢â¬â¢s role in the world continues to grow in importance even as we sometimes take it for granted. We must realize how greatly computers have affected our lives. Computers have become such an integral part of our lives because we rely on them for numerical calculations, storage of data, communication, and technological processes. Ã Ã Ã Ã Ã The idea of computing began at the start of civilization. The computerÃ¢â¬â¢s long history makes it, Ã¢â¬Å"Ã¢â¬ ¦ one of the most interesting and important machines ever inventedÃ¢â¬ (Anonymous). Computers are simply complex counting devices. The abacus was an ancient computer which used beads to solve math problems. The abacus was strictly manual and the desire for an automated machine grew. One of the earliest automated machines was invented in the nineteenth century when French weaver, Joseph Jacquard, created a loom that could be programmed. Large hole punched cards were used by the loom to create geometric patterns. Aside from producing beautiful patterns, the punched cards were later modified to become the main form of computer input. The system of punch cards led to the first successful semi-automated computer, a punch-card tabulating machine invented during the 1880s by American Herman Hollerith. It was used to tabulate the results of the U.S. censu s. Each punch card contained the data of each individual. Operators fed the countless cards into the computer. When the spring-mounted nails of the computer passed through the holes of the punch-card, an electric circuit was completed. As seen in diagram C, the results of each card were displayed on rows of dials. HollerithÃ¢â¬â¢s company, the Tabulating Machine Company, was eventually sold and was renamed the International Business Machines Corporation (IBM) in 1911, which still exists today. The first electronic computers were very large and elaborate machines that required a lot of money to build and use. The entire computer industry might never have taken off without government funding. World War II created a need for the U.S. military to calculate missile trajectories quickly, so Dr. John Machly was hired by the military to build a machine for this task.
