The tremendous（巨大的，极大地的 ）reduction over the last decade in the cost （成本）of digital electronic devices has led to an explosive growth in the use of computers . At the same time, our increased understanding of computer science has made possible the development of new software systems of increased power, sophistication, and flexibility.
