What is the Ethernet bridge?
Ethernet bridge is a type of computer network device that connects two or more different network segments. It overcomes some inherent limitation of the widely used Ethernet network technology actively by controlling data flow between network segments and transmits only those data that originates from one segment and are designed for the other. The Ethernet bridge reduces the overall network overload and allows you to create larger and more complex networks. Other network interfaces can connect Ethernet segments compared to technologies such as Wi-Fi® and network networks. Ethernet -based networks can be extremely complex and connect computers, printers and other sources of the whole company. However, the number of devices in the network and the geographical area, which may include the network, is limited by some of its own characteristics. Only one device or a "node" in the network can be transmitted at the same time, and a larger number of nodes in the network means a better chance of a disturbing collision in which two or nodes are sent by data at once. Electrical signals usedTechnology can also worsen how the wire length increases, limiting the practical maximum distance of the Ethernet cable.
Several types of network devices can be used to combat the Ethernet technology. The early device known as a repeater could expand the range of Ethernet cable by exceeding electrical signals but had no collision protection. In more modern networks, Ethernet, bridge or router can be used to segregate network traffic and prevent collisions. Historically, bridges had only two Ethernet ports, one for each network segment, but many manufacturers used the terms switch and bridge inner and the bridge can have many ports today. Routers are more complex devices with advanced functions.
Ethernet bridge serves as a demarcation point between network segments and binding between these segments. The bridge actively manages the flow of data between two or more segmenthese and only transmits data from one segment and intended for another; The road between the two nodes in the same segment will not be handed over by the bridge. This reduces the overall overload of the network and allows you to create a larger LAN. The bridge also repeated the signals to prevent degradation of longer distances.
Although the Ethernet bridge must include at least one Ethernet port by definition, it may include other types of network interfaces to facilitate Ethernet bridging. At the consumer level, the Ethernet bridge could be used to connect the small network segment of the home cinema equipment and the video game consoles to the rest of the network via Wi-Fi® or by means of the outlets and electrical wiring of the house or apartment. More powerful equipment can wirelessly connect the entire office with the second building several kilometers or kilometers away. Software programs also allow conventional computers to turn into Ethernet bridge, provided the machine has more than one Ethernet port.
