Repeater (repeater) - is a device amplifier (regenerates and extends the network signals). For example, if the network is made of twisted-pair category 5 UTP Ethernet is the maximum length, which can send data is 100 meters. Repeater can be used to increase the length. Concentrator (hub) - is a device similar to the Repeater. In fact it is multi-port Repeater. Concentrators send a signal to all its ports or as a host sends a message that is sent to each host connected to the hub. Most (bridge) - create two or more network segments. What is it? For Repeater Hub and data are sent everywhere, in the case of the bridge shall be communicated to the appropriate segment. Bridges process data in the network and direct the movement of such data. For example, the network consists of 8 PCs connected in a way that: - 4 computers are connected by a hub, - The second four computers connected with each other is the hub, - The two hubs are connected together via a bridge. And now, yes. The bridge has created two segments on 4 computers. In the case of sending data between two hosts in one segment, hosts the second segment do not process the data. The proposal is that bridges may be due to better use bandwidth.
