综合篇 IT业界变化最快的莫过于硬盘的容量,在世纪之交的今天,其增长幅度已达一年两倍乃至多倍。大容量硬盘的普及既与计算机技术的全面发展密不可分,也与信息时代的数据量猛增关系甚大。一方面,随着CPU主频的直线上升,系统内存成倍增加,响应时间也迅速缩短,系统高速缓存Cache不但已广为采用,而且容量也越来越大。整机运行速度和处理能力等硬件性能的极大提升,又相应刺激了软件系统的飞速发展,高性能、多功能、自动化、智能化、图形化、人性化以及安全可靠等特点已成为现代软件的基本特征。另一方面,无论是个人电脑的系统程序和应用文件,还是网络客户机及服务器的操作系统和管 Integrated article IT industry changes the fastest than the hard drive capacity, at the turn of the century, its growth rate has doubled or even multiple times a year. The popularization of high-capacity hard drives is not only inseparable from the overall development of computer technology, but also has a great relationship with the data volume in the information age. On the one hand, as the CPU clock speed rises linearly, the system memory multiplies and the response time rapidly decreases. The system cache caches are not only widely used, but also have larger and larger capacities. The overall performance of hardware such as overall running speed and processing power has been greatly improved, which in turn has stimulated the rapid development of software systems. High-performance, multi-functional, automation, intelligent, graphic, humanized and safe and reliable have become modern software The basic characteristics. On the other hand, both the PC’s system programs and application files, as well as the network client and server operating system and management
