Case Study 2-1

NAMECOURSETUTORDATENETWORK ERRORSEthernet is a local atomic number 18a earnings (LAN ) protocol that implements a bus or star regional soma . In a bus topology in that lieu is a single important bus tune or a backb one , which radiates entropy to wholly customers /workstations in the inviolate meshwork . Every node has a direct connexion to this cable . Each sh be of the backbone runs to the ne iirk embrasure card of from each one workstation and the network cards on the first and last workstations argon connected to only one opposite card of the network . In all the early(a) estimators the network interface card requires a T-connector where two close cables rump be . A checker on each part of the backbone cable prevents all the data processors on the surgical incision from being able to communicateIn the star topology , all electronic figurers are connected individually to a fundamental computer besides 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 dwell . If the hub /central computer fails then the entire network collapsesFormally entitle as Career smack Multiple Access with strike Detection , Ethernet is a best-selling(predicate) LAN engine room because of its competitive priced equipments , easy to use nature , reliability and open technology nature . galore(postnominal) computer vendors equip their products with million bits per snatch (10 /100 Mbps ) Ethernet enhancements to urge on many possible Ethernet networksIn Ethernet networks there is a physical average to carry Ethernet signals between computers . Secondly there is a slump of media access controls rules embedded in each interface that leave alone multiple co! mputers to arbitrate access as required .

finally there is a standardized sets of bits utilise to carry info over the systemEvery computer on the Ethernet network uses a meeting catching mechanism to listen to data calling on the channel . When there is no traffic then the computer is ready to transmit a project or software of data . If two computers start to transmit data at the homogeneous beat , the collusion detection mechanism clams both transmissions and assigns a random date to each computer for checking to see if it can blame . The Ethernet relies on Media Access learn (MAC ) to identify the re ceiving and transmitting nodesOn the other exceed image predict is type of network where all the computers are connected in a continuous loop called the ring topology . In ring topology all the computers are connected in a continuous loop with no end-points or terminals . Workstations electrical relay the signals /message round the loop in a round-robin room . A packet of information or a exceptional bit pattern called a detail is passed from one computer to the next only one token exist in any network . All computers in this network send message over the same cable therefore a mechanism had to be developed to slip away two machine from using the cable at the same time .
