What is a bridge, which kind person can give a detailed explanation? 10

A bridge is an early two-port Layer 2 network device used to connect different network segments.

The bridge is like a clever repeater that takes signals from one network cable, amplifies them, and feeds them to the next. In contrast, bridges are more sensitive to information uploaded from levels, and bridges are a technique that performs the best on frames, isolating collisions according to MAC partitions.

Bridges connect multiple segments of a network at the data link layer. A bridge, also known as a bridge, is a storage device that connects two LANs, which can split a large LAN into multiple network segments, or interconnect more than two LANs into a logical LAN, so that all users on the LAN can access the server.

Bridge connection method

1. Since all wireless bridge equipment is powered by PoE, it is extremely important to correctly connect the PoE power supply box, wireless Chunzhi bridge, IP camera and other equipment.

2. Installation and fixation of wireless bridge equipment. When installing the wireless bridge, be sure to fix the bracket, if the bracket is unstable, it will directly affect the stability of microwave signal transmission. When fixing the wireless bridge to the bracket, fix the wireless bridge firmly according to the fixing method, during installation, because the surface of the bracket is relatively smooth, if the U-shaped clamp code is tightened directly with a nut, it may take a long time, the surface of the bracket will be rusted when the outdoor rain penetrates, and the contact between the U-shaped clamp code and the bracket will be loosened.

Bridges provide an inexpensive and convenient way to connect local area network (LAN) segments. An LAN segment is a single part of a network** that connects computers. For example, let's say you have three computers:

Computer A, Computer B, and Computer C. Computer A has two Ethernet adapters, while Computers B and C each have one Ethernet adapter. The Ethernet cable connecting A and B will create a LAN segment, and the other Ethernet cable connecting A and C will create another LAN segment.

Traditionally, if you need your network to have multiple segments, you have two options: routing and bridging. IP routing is a common solution for connecting network segments.

However, if you want to install IP routing, you must purchase a hardware router or install a computer at the junction between network segments to use as a router. For each computer on each network segment, IP routing requires complex configuration of IP addresses, and each network segment needs to be configured as a separate subnet. IP routing is a suitable solution for large networks, where scalability is important and requires experienced staffing to configure and maintain the network.

Bridges don't require complex configuration, but you'll have to purchase additional hardware bridges. Neither option is ideal if you're a home or small office network, and you're reluctant to buy expensive bridging hardware or have experienced personnel manage your IP routing network.

With bridges, you can connect different LAN segments by selecting the appropriate network connection icon and clicking Bridge. Similarly, it is convenient to enable the bridge and add connections to it. Bridges manage network segments and create individual subnets for the entire network.

No configuration is required, and no additional hardware (such as routers or bridges) is required. In a single subnet IP network, IP addresses, address assignments, and name resolution will be very easy.

Bridges can create connections between different types of networks**. In a traditional network, if you use a hybrid type, you need a separate subnet for each type, and you need to packet data across multiple network subnets. Because different types use different protocols, packets are required.

The bridge automates the configuration necessary to move information from one to another.

Only one bridge can exist on a Windows XP computer, but you can use it to bridge all the network connections that the computer physically allows. For information about creating bridges, see Bridges.
