摘  要

局域网(LAN)的名字本身就隐含了这种网络地理范围的局域性。由于较小的地理范围的局限性，我们对它进行规划。本文就是从局域网规划与组网两个方面进行分析与总结。

首先我们介绍了什么是LAN。从LAN的发展史、基本组成、网络操作系统等多方面对LAN进行了概述。然后从局域网规划与组网需要进行的步骤逐步分析。最后是对无线局域网(WLAN)的展望。

关键词：局域网，组建，规划

Abstract

The name of the LAN itself implied the limitation of the network geography scope.We plan it due to the less limitation of geography scope .The thesis concluded and analyzed two aspects of the.

This article expounded the concept of the LAN firstly.Secondly it presented a panorama of the developmental history,Basic Component and Network Operating System of the LAN.Then it analyzed progressively the step of the LAN plan and the network。At last prospect of the WLAN was given by the author.

Keywords: LAN, Plan, Network
