Chapter 7 Programming Languages 7.2 Object-Oriented Programming While computers, the hardware, underwent revolution after revolution, using faster and ever more powerful components, the software technology has significantly lagged behind in matching these advances. Hardware technology has been revolutionized several times: from tubes to discrete transistors, resistors and capacitors to board-level integration to integrated circuits. Even integrated circuits have undergone several significant evolutionary steps: from large-scale integration (LSi) technology to very large scale integration (VLSI), and eventually wafer scale integration. Hardware engineering was able to keep up with this pace by developing new techniques to manage the exploding complexity of a modern computer system 当计算机硬件由于使用速度更快、功能更强的器件而不断更新换代的时候,软件 技术则大大滞后,与硬件的发展不相匹配。硬件技术已经历了几次革命:从电子 管到单个晶体管、电阻和电容器元件,到板级集成电路,到整个集成电路。即使 是集成电路也经历了几次重大的演变:从大规模集成电路(LS技术到超大规模集 成电路(vLS,并且又发展了晶片上大规模集成技术。硬件工程能够保持这种发 展势头,是因为新技术的发展可以对付现代计算机系统与日俱增的复杂性。710Chapter 7 ProgrammingLanguages 计算机专业英语 7-10 7.2 Object-Oriented Programming While computers, the hardware, underwent revolution after revolution, using faster and ever more powerful components, the software technology has significantly lagged behind in matching these advances.
