The computer is the tool that can perform numerical calculations in just billionths of a second. It can memorize vast amounts of information and recall it at the press of a button. It is a tireless workhorse that never complains as long as there is electricity running inside its microprocessor. Although a computer is unable to make any kind of decision by itself or to think in any way, it becomes a faithful servant of the human mind under the inspiration, intent, and skill of its programmer. Today, we find computers in nearly all aspects of our lives.
Computers are fast, reliable machines that receive, store, and use information.
They are found in nearly every aspect of our lives. Today it would be very difficult to find any profession or human endeavor that does not use or benefit from computers. They are used as a productivity tool in the business environment to increase efficiency and profitability. Governments rely on computers for their national defense, collection of taxes, and demographics. Science and medicine use computers to predict volcanic eruptions and diagnose cancer.
