引言采用局部网络技术可以把许多微型计算机连接起来,增强微型机的功能,扩大其应用范围。用多台微型机联成局部网络可以取代中小型机的作用,来实现分布处理和分散管理,这不仅能方便应用和减少通信成本,而且也能增加系统的可靠性。因为网络中数台微型机都出故障的可能性是极小的,一台微型机出故障只能是对局部有影响,对网络本身无多大影响。
Introduction Local network technology allows many microcomputers to be connected to enhance the functionality of the microcomputers and expand their range of applications. The integration of multiple microcomputers into local networks can replace the functions of small and medium-sized machines to achieve distributed processing and decentralized management. This not only facilitates the application and reduction of communication costs, but also increases the reliability of the system. Because there are few microcomputers in the network that have the possibility of failure is very small, a microcomputer failure can only affect the local impact on the network itself.
