从本世纪四十年代中期出现第一台电子计算机以来,虽然只有四十年不到的历史,但是计算机技术(包括硬件、软件和应用)已有了长足的进步,经历了整整四代。第一代大体上从一九四六年到一九五七年。这一代计算机采用电子管元件,体积大,功耗高,运算速度约为每秒八千次。这从当时的观点来看已是 Since the emergence of the first electronic computer in the mid-1940s, although it is only less than 40 years old, computer technology (including hardware, software, and applications) has made great progress and has gone through a full four generations. The first generation was generally from 1946 to 1957. This generation of computers uses electronic tube components that are bulky, consume high power, and operate at about 8,000 operations per second. This is already from the perspective of the time
