Computer

Said the computer was originally used to describe people whose jobs do arithmetic calculations, with or without a walker, but the word is then transferred to the machine itself. ENIAC, the U.S. early computers originally designed to take into account ballistics tables for weapons (artillery), calculate the density of neutron cross-section to see if a hydrogen bomb would work properly (this calculation, conducted in December 1945 until January 1946 and involved dala in more than one million punch cards, and then show the form under consideration would fail). CSIR Mk 1/CSIRAC, Australia's first computer, evaluated rainfall patterns for the catchment of the Snowy Mountains, a large Hydroelectric generation projects. It is also used in cryptanalysis, for example, the first digital electronic computer, Colossus, built during World War II. However, early visionaries also think that it will allow programming to play chess, moving images and other uses

Invention of the microprocessor in the 1970s, became possible to produce a very low-cost computers. PCs are becoming popular for many tasks, including keeping books, writing and printing documents. The calculation of forecasts and other repetitive math with lembatang scatter, related to e-mail and, the Internet. However, the widespread availability of computers and easy customization has seen them used for many other purposes. Simultaneously, a small computer, usually by adjusting the programming, started finding their way into other devices such as home appliances, automobiles, airplanes, and industrial equipment. Embedded processors which are controlled behavior of such devices easier, allowing more complex control behavior (for events, development of anti-lock brakes in cars). When the twenty-first century begins, most electrical devices, most forms of powered transport, and most factory production lines are controlled by computers.

People in government and large companies also use computers to automate the data collection and many tasks previously done by humans - for example, maintain and update accounts and inventory. In the field of education, scientists in various fields began using computers for their own analysis. Decline in computer prices to make them can be used by smaller organizations. Businesses, organizations, and governments often use very many small computers to complete tasks that were once performed by main frame computers are expensive and bulky.
