检修局域网对大部分的用户而言,似乎是件难于克服的困难.绝大多数的网络故障发生在所用的传输媒介或是电缆中.寻找故障主要的困难之一是因为电缆被埋在建筑物的墙壁、地板或者天花板里.问题经常不是出在电缆自身上,而是出在人们的疏忽上——电缆及网络器件的选择及它们的安装和使用上发生错误.在还没有说明检修网络的测试方法之前,我们先复习一下常用的网络的一些重要特性和连接局域网的必备条件.局域网的布置局域网是工作站、服务器、共享资源及其他网点的集合体,通常是使用共同的传输媒介连接,并且以共同的存取规则来进行通信.局域网布局图描绘实体的位置和器件是如何连接的,这也是检修网络的第一步要了解的.有一份表示局域网布局的接线图,就如同在出外旅行时,手上有份地图一般.目前有两种基本的布局方式(如图1):一种是线
Overhauling the LAN appears to be hard to overcome for most users. Most network problems occur with the transmission medium or cable used. One of the major difficulties in finding a fault is that the cable is buried in a building Of the walls, floors or ceilings.The problem often does not lie with the cable itself, but with negligence - the choice of cables and network components and their installation and use is erroneous. Before testing the method, we first review some of the important features of commonly used networks and the prerequisites for connecting to the LAN.Local Area Network LAN is a collection of workstations, servers, shared resources and other outlets, usually using a common transmission medium to connect, And with common access rules to communicate. LAN layout diagram depicts the location of the entity and how the device is connected, which is the first step to repair the network to understand. There is a wiring diagram that LAN layout, just as out Travel, there are copies of the map in hand there are two basic layout (Figure 1): one is the line
