橋接器和掃描儀模塊在功能和應(yīng)用上有所不同。
橋接器是用于在兩個或多個網(wǎng)段或子網(wǎng)間提供通信路徑的互聯(lián)設(shè)備。這些網(wǎng)段或子網(wǎng)具有相同的地址及同類網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)。橋接器的主要作用是連接網(wǎng)絡(luò)段的兩端口(或多端口)設(shè)備,允許網(wǎng)絡(luò)上的工作站利用它向其它網(wǎng)上的工作站廣播消息。此外,橋接器還可以將業(yè)務(wù)忙的網(wǎng)絡(luò)分為兩段,減少每段上的通信量以提高性能,并過濾網(wǎng)絡(luò)廣播信息,只允許必要的通信信息通過橋接器到達(dá)另外的網(wǎng)絡(luò)。

The bridge and scanner modules differ in function and application.
A bridge is an interconnecting device used to provide a communication path between two or more network segments or subnets. These network segments or subnets have the same address and the same network topology. The main role of a bridge is to connect two-port (or multi-port) devices on a network segment, allowing workstations on the network to use it to broadcast messages to workstations on other networks. In addition, the bridge can also divide the busy network into two segments, reduce the traffic on each segment to improve performance, and filter the network broadcast information, allowing only the necessary communications to reach the other network through the bridge.
