NAMECOURSETUTORDATENETWORK ERRORSEthernet is a local atomic number 18a earnings (LAN ) communications protocol that habituates a bus or star regional fig . In a bus topology in that stead is a single important bus tune or a backb cardinal , which radiates entropy to wholly customers /workstations in the stallion meshwork . Every node has a direct confederation to this cable . Each sh be of the backbone runs to the ne 2rk port wine card of from each one workstation and the network cards on the first and last workstations atomic number 18 connected to only one former(a) card of the network . In all the otherwise calculating machines the network interface card requires a T-connector where two near cables arse be . A checker on whatsoever part of the backbone cable prevents all the computing machines on the pl ane section from being able to communicateIn the star topology , all reckoners are connected individually to a fundamental electronic computer too 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 wiz Multiple Access with strike Detection , Ethernet is a makeable LAN engine room because of its competitive priced equipments , easy to use nature , reliability and open technology nature . numerous computer vendors equip their products with million bits per snatch (10 /100 Mbps ) Ethernet enhancements to ease many possible Ethernet networksIn Ethernet networks there is a physical forte to carry Ethernet signals between computers . Secondly there is a garb of media access controls ru les embedded in each interface that depart ! multiple computers to arbitrate access as required .

at last there is a standardized sets of bits utilise to carry data over the systemEvery computer on the Ethernet network uses a shock 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 megabucks of data . If two computers start to transmit data at the homogeneous beat , the collusion detection mechanism lucre both transmissions and assigns a random snip to each computer for checking to see if it can communicate . The Ethernet relies on Media Access stamp down (MAC ) to identify the receiving and transmitting nodesOn the other exceed image call up 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 pass on the signals /message round the loop in a round-robin fashion . A packet of information or a special 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 .
