信息技术是现代社会中发展最迅速、竞争最激烈、影响最广泛的技术领域,其核心是计算机与通信技术,其基础是微电子技术。 从1946年世界上第一台电子计算机问世以来,计算机的计算速度差不多提高了1亿倍。计算机现在已应用于社会生活的各个方面,形成了一个年销售量数千万台的巨大工业。在计算机的发展中,微电子技术的进步起到了特别关键的作用。1965年Intel的创始人之一Gordon Moore提出了著名的“摩尔定律”:在一个芯片上集成的晶体管数量,每18个月将会翻一番。迄今为止,技术的进步一直很好地遵循着这条定律。如今在CPU芯
Information technology is the fastest growing, most competitive and most influential technology in modern society. Its core is computer and communications technology, which is based on microelectronic technology. Since the world’s first electronic computer was introduced in 1946, the computational speed of computers has increased almost 100 million times. Computers have now been applied to all aspects of social life, forming a huge industry with tens of millions of annual sales. The advances in microelectronics have played a particularly crucial role in the development of computers. Gordon Moore, one of Intel’s founders, made the famous “Moore’s Law” in 1965: The number of transistors integrated on a single chip would double every 18 months. So far, technological advances have followed this law very well. Now in the CPU core
