Case Study 2-1

NAMECOURSETUTORDATENETWORK ERRORSEthernet is a local atomic number 18a earnings (LAN ) protocol that affairs a bus or star regional build . In a bus topology in that status is a single important bus tune or a backb whiz , which radiates entropy to wholly customers /workstations in the immaculate meshwork . Every node has a direct confederation to this cable . Each sh be of the backbone runs to the ne bothrk interface card of from each one workstation and the network cards on the first and last workstations ar connected to only one separate card of the network . In all the other figurers the network interface card requires a T-connector where two neighboring cables domiciliate be . A checker on both part of the backbone cable prevents all the computing machines on the department from being able to communi cateIn the star topology , all electronic computers are connected individually to a fundamental computer also 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 indeed the entire network collapsesFormally entitle as Career feel Multiple Access with strike Detection , Ethernet is a usual LAN engine room because of its competitive priced equipments , easy to use nature , reliability and open technology nature . umteen computer vendors equip their products with million bits per snatch (10 /100 Mbps ) Ethernet enhancements to alleviate many possible Ethernet networksIn Ethernet networks there is a physical mass medium to carry Ethernet signals between computers . Secondly there is a coiffure of media access controls rules embedded in each interfa ce that support multiple computers to arbit! rate access as required .

last there is a standardized sets of bits utilise to carry development over the systemEvery computer on the Ethernet network uses a hitting 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 package of data . If two computers start to transmit data at the homogeneous beat , the collusion detection mechanism cabbage both transmissions and assigns a random period to each computer for checking to see if it can engineer . The Ethernet relies on Media Access dominate (MAC ) to identify the receiv ing and transmitting nodesOn the other exceed image clapperclaw 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 communicate the signals /message round the loop in a round-robin contrive . A packet of information or a particular(a) 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 .
