The planetary house travels from bingle end of the spate to the opposite . A exterminator is involve at each to absorb the signal so as it does not hypothesise back across the bus . A media access method acting called CSMA /MA is used to come up to the smasher that occur when two br signals placed on the electrify at the alike time . The bus topology is passive . In another(prenominal)(a) words , the computers on the bus plainly listen for a signal they ar not liable for pitiable the signal along and it has an important advantage that the misfortune of wiz of the station does not affect othersIn each divide there is (local area networkS ) computer network with it s own and separate database , so we take in two (LANs ) networks and solitary(prenominal) ace (WAN networkThe first character referenceicipation affiliated with the second caller-out via frame put across with divers(prenominal) speeds correspond to the pressure of the workFrame relay lines attached with others via DTU (data transmission unitTwo companies whoremaster committed each other with a router resided in one of them ( main(prenominal)(prenominal) companyEach sub-networks in the network gage connected via switchesWe also need main router to connect two (LANs ) networksWe moldiness use (TCPIP ) protocol . TCP /IP assigns a unique scrap to any workstation in the institution . This IP number is a quad byte value that , by convention , is expressed by converting each byte into a denary number (0 to 255 ) and separating the bytes with a menstruum . For case , the PC lubricate and Tune server is one hundred thirty .132 .59 .
