先决条件 – 网络设备
桥:
网桥在第二层运行,即 ISO-OSI 模型的数据链路层。它将使用相同协议的两个网络连接在一起。网桥相对容易配置并且专注于 MAC 地址。
中继器:
中继器是一种电子设备。它是用于扩展局域网的硬件设备。中继器仅在物理层上运行,即 OSI 模型的第一层。它重新生成弱信号并增加网络的范围。通过使用中继器,网络的功能保持不变。交换机可以用作中继器,但集线器不能用作中继器。
让我们看看桥接器和中继器之间的区别:
S.No. | Bridge | Repeater | |
---|---|---|---|
1. | Bridge operates at the data link layer of OSI Model. | Repeater operates at the physical layer of OSI Model. | |
2. | The complete frames is understand by bridge. | Repeater do not understand complete frames. | |
3. | Destination address is used in the bridge to determine in case to forward a frame. | Repeater are not able to recognize the destination address. | |
4. | In the network, if collision occurs in the one segment is not forwarded to another segment by bridge. | Repeater forward the collision from one segment to another, which causes the same issue to be occured on all other segment in the network. | |
5. | Bridge connects two network in a well organized manner. | Repeater expands the limit of the signals in the network. | |
6. | Filtering of the packets in network is achieved by the bridge. | Repeater cannot performs packet filtering. | |
7. | Bridges are relatively expensive and used to extend a LAN. | Repeater is also used to extend a LAN, but comparably economical than the bridge. |
