一、局部网络概述近年来,计算机局部网络技术已成为计算机领域的重要研究课题。特别是将微型机网络化已成为扩大微型机应用的必然道路。所谓局部网络,一般是指将分布在数公里之内的(通常是一座建筑物内或一个小的建筑群中)数以百计的计算机、终端以及各种控制机器等用极高的数据传输率(通常为1M～10Mbps)互联在一起,实现资源共享。 First, the local network overview In recent years, the computer local network technology has become an important research topic in the field of computer. In particular, the network of microcomputers has become the inevitable way to expand the application of microcomputers. The so-called local network, generally refers to the distribution within a few kilometers (usually a building or a small building complex) hundreds of computers, terminals and various control machines with extremely high data transmission Rate (usually 1M ~ 10Mbps) interconnect together to achieve resource sharing.
