局部计算机网(Local Compurer Network)是跨越地理范围较小的计算机网,简称局部网(LCN).它是计算机网络技术、并行处理和分布式处理等结合的产物.局部网能很方便地连结小型机和微型机来满足局部地区内的资源共享,经济上投资少,近年来在计算机网领域内十分活跃.一、局部网的特点、结构和分类(一)局部网的特点局部网一般具有五个特点:1.一般由一个单位经营管理.2.部件之间的距离在几公里之内,最典型的是一公里.3.网中可以互相
Local Compurer Network is a computer network spanning a relatively small geographical area, referred to as Local Area Network (LCN), which is a combination of computer network technology, parallel processing and distributed processing, etc. The Local Area Network can easily link small Machines and microcomputers to meet the local area resource sharing, less investment in the economy, in recent years in the field of computer networks is very active.First, the characteristics of local networks, structure and classification (a) the characteristics of local networks Local networks generally have five A feature: 1. Generally operated by a unit management .2. The distance between components within a few kilometers, the most typical is one kilometer. 3. Net can mutually
