The main function of a Hub Made in china of the received signal is shaped enlarged reproduction, to extend the transmission distance of the network, while all the nodes in the cluster with its center on the node.
A Hub Made in china is used to connect devices in a local area network having a plurality of ports for connecting multiple computers. Often to the LAN Hub Made in china as the center, all distributed workstations and servers linked together to form a joint topology of the LAN system. In addition to the advantages of Hub Made in china interconnecting a plurality of terminals outside, the advantage is when one of the nodes of the line failure will not affect other nodes.
With the development of technology, especially in the LAN - some medium-sized local area network, the Hub Made in china has been excluded from the application, and the switch was replaced. At present, the main Hub Made in china used in a number of small and medium network edge portion or medium-sized networks. The following characteristics of small and medium local area network applications, introduces its selection.
In a local area network Hub Made in china (LAN) environment, as the same card, is applied to the first layer of the OSI reference model, it is also called the physical layer device.
Hub Made in china internal use of Internet appliances, while maintaining LAN environment is a logical bus or ring structure when fully established star or tree topology with a physical Hub Made in china . In this regard, the role of the Hub Made in china corresponds to a multi-port repeater. In fact, actually a repeater Hub Made in china , which differ only in the Hub Made in china ports can provide more services, so called multi-port repeater Hub Made in china .
