				Engineers have developed a very complicated circuit — called an integrated circuit — that combines thousands to millions of parallel and series circuits working together. One type of integrated circuit that works as a complete computation engine is a microprocessor, known as a central processing unit or a CPU. Microprocessors are essential in automobiles, video games, smoke detectors, DVD players, garage-door openers, cordless phones, clocks and calculators. Engineers continuously develop new techology so that they may use electricity to find solutions to everyday challenges — efforts that contribute to a healthier, happier, and safer environment.
