自PC机问世以来的十五年间,其体积逐步缩小。从桌式机到膝上机到便携机,它们的工作方式都是相同的,均带有一个击打式键盘和基于DOS或Macintosh的操作系统。在过去的岁月里,体积的不断缩小导致了各种手持系统的产生。如个人数字助手(PDA),个人通信系统等。这些看上去仅仅是体积的缩小,实质上却是自IBM PC机诞生以来一个重大的变革。这一变革将产生系统行业方面的新的领导者,使许多服务行业兴起,也引起了微处理器结构的变革。这一工业所面临的问题仍
In the fifteen years since the advent of the PC, its size has been gradually reduced. From desktops to laptops to laptops, they all work the same way, all with an impact keyboard and DOS- or Macintosh-based operating system. In the past years, the ever-shrinking volume led to the emergence of a variety of hand-held systems. Such as personal digital assistants (PDAs), personal communication systems and the like. These appear to be just the size of the reduction, but in essence it is a significant change since the birth of IBM PC. This change will lead to new leaders in the system industry, the rise of many service industries, also led to changes in the structure of the microprocessor. The problems the industry is facing still
