80年代以来,随着微机技术的飞速发展,局域网(LAN)技术(特别是微机LAN)作为计算机网络的一个重要分支越来越深入到各个应用领域。可以说,只要使用微机,进一步就会考虑配置微机LAN。一、国内LAN用户面临选择问题1986年,美国3Com公司的LAN产品逐渐占领了中国市场,此后几年,一直作为国内微机LAN的主流型号,国内微机网络的应用和软硬件的开发基本上围绕着3COM的产品。1989年下半年,特别是1990年以来,美国Novell公司微机LAN猛烈冲击大陆市场,在国内的微机LAN市场上形成了3COM与Novell激烈竞争的格局。可以说,目前3COM和Novell微机LAN占领了绝大部分的中国大陆LAN市场。一般说来,准备选用微机LAN的用户都面临着三种选择:1.基于DOS的通用系统3+SHARE,这种系统成本低,功能有限,但比较实用,其保密功能和用户接口都
Since the 1980s, with the rapid development of microcomputer technology, the local area network (LAN) technology (especially the computer LAN) has become an important branch of the computer network more and more deeply into various application fields. It can be said that as long as the use of computer, further consideration will be given to configure the computer LAN. First, the domestic LAN users face the problem of choice In 1986, the United States 3Com’s LAN products gradually occupied the Chinese market, the next few years, has been the mainstream model of the domestic computer LAN, the domestic application of computer networks and hardware and software development basically revolves around 3COM products. The second half of 1989, especially since 1990, the United States Novell company LAN violent impact on the mainland market, in the domestic computer LAN market formed a 3COM and Novell fierce competition pattern. It can be said that at present, 3COM and Novell PC LAN occupy most of the LAN market in mainland China. In general, the preparation of computer LAN users are faced with three options: 1. DOS-based Universal System 3 + SHARE, this system is low cost, limited functionality, but more practical, its security features and user interface are
