One reason information systems play such a large role in organizations and affect so many people is the
soaring power and declining cost of computer technology. Computing power, which has been doubling
every 18 months, has improved the performance of microprocessors over 25,000 times since their invention
30 years ago. With powerful, easy-to-use software, the computer can crunch numbers, analyze vast pools of
data, or simulate complex physical and logical processes with animated drawings, sounds, and even tactile
feedback.
