Repeater operates at physical layers of osi model. Digital signals or analog signals that jam digital data can only be transmitted all over a peculiar(a) distance. After a certain distance attenuation or noise endangers the integrity of that data. Repeaters reproduce and transmit the received digital data. This new signal is the exact duplicate of the original signals. Repeaters offer elemental means to extend a engagement, increased traffic on the network is introduced. This increased network congestion may not be congenial in some situations.Switch Communication networks may be reason by the architecture and techniques they give to transfer data. The following types of networks ar in common.Broadcast dialogue networks. Local area networks.Packet radio networks.planet networks.In broadcast communication networks, thither are no middling switching nodes. Each node in the network is attached to cover communication medium. Ethernet and Arc net are examples of broadcast com munication networks.Switched communication networksCircuit switched networksMessage switched networks.Packet switched networks.In switched communication network networks there may be multiple paths linking sender and receiver. Data is transmitted from origin to destination by being routed through the networks nodes. This is called switching.Bridges are limited to extend the network distance up to the network limitations. Bridges are useful to extend the network when dealing with one network. Also bridge limit wide-cut company to use one network. At belong when using bridges a failure in the network affects the entire network and thus the entire company.Routers can extend the network beyond the limitations of a network by connecting two or more networks. Routers waive extending the network by dealing with many networks. Routers also allow you to use a backbone network for faster transfer of information crossways the different networks.
