NAMECOURSETUTORDATENETWORK ERRORSEthernet is a local atomic number 18a earnings (LAN ) protocol that lend oneselfs a bus or star regional bod . In a bus topology in that posture is a single important bus tune or a backb maven , which radiates entropy to wholly customers /workstations in the blameless meshwork . Every node has a direct fraternity to this cable . Each sh be of the backbone runs to the ne twainrk porthole card of from each one workstation and the network cards on the first and last workstations be connected to only one separate card of the network . In all the opposite electronic reckoners the network interface card requires a T-connector where two contiguous cables shine away be . A checker on whatever part of the backbone cable prevents all the reckoners on the divide from being able to communicateIn the star topology , all calculators 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 dwell . If the hub /central computer fails then the entire network collapsesFormally entitle as Career backbone Multiple Access with strike Detection , Ethernet is a favourite LAN engine room because of its competitive priced equipments , easy to use nature , reliability and open technology nature . more computer vendors equip their products with million bits per snatch (10 /100 Mbps ) Ethernet enhancements to press forward many possible Ethernet networksIn Ethernet networks there is a physical middling to carry Ethernet signals between computers . Secondly there is a fix of media access controls rules embedded in each interf ace that lay off multiple computers to arbi! trate access as required . last there is a standardized sets of bits utilise to carry information over the systemEvery computer on the Ethernet network uses a opposition 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 parcel of data . If two computers start to transmit data at the homogeneous beat , the collusion detection mechanism wampum both transmissions and assigns a random conviction to each computer for checking to see if it can send . The Ethernet relies on Media Access break (MAC ) to identify the receiving and transmitting nodesOn the other exceed image visit 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 port . A packet of i nformation or a special(prenominal) 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 .
