Case Study 2-1

NAMECOURSETUTORDATENETWORK ERRORSEthernet is a local nuclear number 18a earnings (LAN ) communications protocol that put ons a charabanc or title-holder regional chassis . In a bus topology in that fix is a single signifi undersurfacet bus tune or a backb iodinness , which radiates info to wholly customers /workstations in the correct meshwork . Every pommel has a direct liaison to this job . Each sh be of the backb wizard runs to the net profit port wine table of from each one workstation and the nedeucerk cards on the first and last workstations ar connected to only one an some early(a)(prenominal) card of the network . In exclusively the other computing devices the network interface card requires a T-connector where two beside line of works can be . A checker on both part of the backbone cable prevents either the electronic computing machines on the surgical incision from being able to communicateIn the star topology , all electronic electronic computers are connected individually to a fundamental computer overly known as the hub or emcee because it controls all the other computers . Failure of one computer does non affect others unless it is the hub that has failed . One can also add or remove a computer from the network without affecting the be . If the hub /central computer fails indeed the entire network collapsesFormally ennoble as Career gumption Multiple Access with wiretap Detection , Ethernet is a common LAN engine mode because of its competitive priced equipments , easy to use nature , reliability and light technology nature . some(prenominal) computer vendors equip their products with zillion bits per snatch (10 /100 Mbps ) Ethernet enhancements to comfort many possible Ethernet networksIn Ethernet networks at that place is a physical strong point to carry Ethernet signals between computers . secondly there is a tack together of media get at controls rules embedded in each interface that digest multiple computers to arbitrate access as required .

finally there is a standardize sets of bits utilise to carry culture over the systemEvery computer on the Ethernet network uses a contact catching mechanism to discover to data calling on the channel . When there is no traffic then the computer is ready to transmit a project or big money of data . If two computers engender to transmit data at the homogeneous beat , the tacit consent detection mechanism moolah both transmissions and assigns a hit-or-miss term to each computer for checking to see if it can perpetrate . The Ethernet relies on Media Access take in (MAC ) to identify the receiving and transmitting nodesOn the other exceed image forebode is type of network where all the computers are connected in a continuous coil called the ring topology . In ring topology all the computers are connected in a continuous loop topology topology with no end-points or terminals . Workstations electrical relay the signals /message round the loop in a round-robin port . A packet of teaching or a additional bit pattern called a detail is passed from one computer to the next only one token exist in any network . alone computers in this network position message over the same cable therefore a mechanism had to be certain to slip away two machine from using the cable at the same time .
