1.客户服务器(C/S)概述和类比 八十年代中期,人们以为工作站/文件服务器系统结构不错;到了八十年代后期,人们以为主机多用户系统可以实现技术环境的集成。其实,前者只能进行文件共享,后者的用户数目受到限制,两者均不是技术环境集成的最佳方案。九十年代初,客户机/服务器(C/S)结构的出现,克服了前两者的缺点,发扬了两者的优点,成为一种理想的分布式处理环境,C/S结构是大型MIS技术环境集成的最佳结构。 1. CUSTOMER SERVER (C / S) OVERVIEW AND ANALOGS The workstation / file server system was thought to be of good construction in the mid-1980s; by the late 1980s, it was assumed that host multi-user systems could integrate the technology environment. In fact, the former can only file sharing, the latter the number of users is limited, both are not the best technology environment integration program. The early nineties, client / server (C / S) structure to overcome the shortcomings of the first two, carry forward the advantages of both to become an ideal distributed processing environment, C / S structure is a large MIS The best structure for technical environment integration.
