自1946年世界上第一台电子计算机在美国问世以来,计算机工业发展神速。短短三十余年就经历了电子管、晶体管、集成电路和大规模集成电路四代。每隔五到八年,计算机的运算速度就提高十倍,体积缩小十倍,成本却反而降低十倍。微电子技术日新月异的发展使得计算机不断向微型化、系列化发展,从而为计算机的普及和应用开拓了广阔的道路。 Since 1946 the world’s first electronic computer came out in the United States, the rapid development of the computer industry. Just three decades has gone through the tubes, transistors, integrated circuits and four generations of large scale integrated circuits. Every five to eight years, the computing speed of the computer is increased tenfold, the volume is reduced tenfold, and the cost is reduced tenfold instead. The rapid development of microelectronics technology makes the computer continue to miniaturization, serialization of development, thus for the popularization and application of computer has opened up a vast road.
