从四十年代到八十年代,计算机经历了四代: 第一代电子管计算机; 第二代晶体管计算机; 第三代集成电路计算机; 第四代超大规模集成电路计算机。由于微电子学工艺的突破,前四代计算机在硬件结构工艺技术方面有重大的进
From the forties to the eighties, computers went through four generations: the first generation of electronic tube computers; the second generation of transistor computers; the third generation of integrated circuit computers; the fourth generation of very large scale integrated circuit computers. As a breakthrough in microelectronics technology, the first four generations of computers in the hardware structure of a significant technological advances
