Repeater operates at physical layers of osi model. digital signals or analog signals that carry digital data hind end just now be transmitted over a limited distance. After a certain distance attenuation or noise endangers the integrity of that data. Repeaters spue and transmit the received digital data. This new signal is the exact replica of the original signals. Repeaters offer simple means to extend a ne cardinalrk, change magnitude traffic on the network is introduced. This increased network congestion may not be acceptable in some situations.Switch colloquy networks may be categorized by the architecture and techniques they physical exertion to budge data. The following types of networks argon in common.Broadcast communication networks. Local res publica networks.Packet radio networks.Satellite networks.In broadcast communication networks, at that place are no intermediate switching nodes. Each node in the network is attached to share communication medium. Ethernet a nd Arc net are examples of broadcast communication networks.Switched communication networksCircuit switched networksMessage switched networks.Packet switched networks.In switched communication network networks there may be multiple paths linking transmitter and receiver. Data is transmitted from source to destination by being routed through and 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 bridges limit entire company to use one network. At last when using bridges a trial 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 allow extending the network by dealing with many an(prenominal) networks. Routers also allow you to use a backbone network for fast-breaking transfer of information acr oss the different networks.
