LVS - lwenkcubeko yangoku

Okwangoku elikhulu kakhulu ngokubanzi uthungelwano computer. Nabo, abasebenzisi bangasebenza efanayo izixhobo, iinkqubo, iinkcukacha, ngqo yokusebenzela yabo.

Yintoni a LAN?

Olu hlobo luqhelekileyo uthungelwano - local indawo networks.

LVS - uthungelwano computer odibanisa abasebenzisi umatshini esikuyo isikolo kwi umgama ukusuka komnye. Nangona uluhlu uthungelwano ukuya iikhilomitha eziliqela, nto idla isetyenziselwa sokudityaniswa lweekhompyutha kumgama encinane. Ngokuqhelekileyo, lo matshini yokusebenza lweshishini okanye ikhaya iiPC omnye.

ukumisa LAN

Zoqwalaselo kuchazwe LANs kunye nolawulo umncedisi ngaphandle kokuba (kuyalingana).

Peer kwinethiwekhi

Xa unxibelelwano ezinjalo, zonke iikhompyutha ezifanayo ngokwalo iinkcukacha. Peer-to-LAN - uthungelwano yendawo apho ifenishala ngamnye enze yonke imisebenzi ekhoyo zombini client kunye server. Kuba okulinganisa umthwalo kakuhle kwiqela inxaxheba computer LAN ayikwazi ukuba ngaphezulu kwe-10 Kungenjalo, yonke komsebenzi womnatha ubunzima.

iseva ulawulo Network (multilevel)

Xa onjalo LAN yenye iikhompyutha kukuba intsebenzo ezahlukeneyo ngcono, inkumbulo amandla, kunye nakwezinye iimo ezalathayo. Le PC yabelwa ngumncedisi. Aphambili kwi LAN - kukho iikhompyutha kunye namaziko asebenza kwizinga eliphezulu kwaye umthamo memory enkulu xa kuthelekiswa umatshini lwengingqi lomsebenzisi. Nguye obonelela elilujongano kwindlela kwezinye iikhompyutha kwi-network, iivenkile kunye namalungiselelo iifayile karhulumente ukuba ukufikelela kuzo, edlulisela idata umxhasi ngohlobo ulwazi ukwenza okanye siphumo. LAN, iseva lisetyenziswa kuphela apho ukulungiselela data eqhelekileyo, ebizwa uthungelwano kunye neseva ifayile elizinikeleyo. Kunye iinkqubo ezinjalo, kukho LAN, apho umncedisi kwakhona owenziweyo kunye nokulungiswa lolwazi, kwaye ngumxhasi lifumana kuphela isiphumo. Oku kubizwa ngokuba yi-iinkqubo uhanjiselo-server.

LAN ithopholoji

Zonke computer kwi-network kwinqanaba yemvelo ezihambelanayo. LAN yethopholoji efanayo - indlela ukudibanisa umatshini yasekuhlaleni. Ngoku LANs khompawundi kusetyenziswa iindlela ezifana ibhasi, inkwenkwezi, kunye ngomsesane.

ibhasi yethopholoji efanayo

Kwi LAN, apho ibandla icwangciswe ngokwale yethopholoji efanayo isetyenziswa kwindibano intambo omnye, wajoyina umsebenzisi computer zendawo. Ngenxa yoko, ulwazi kwimatshini omnye uhamba bonke abanye. Le umhombiso, leyo abhekiswe i data, ikhetha ulwazi olufunayo ukususela kumsinga jikelele.

Izinto eziluncedo ze ibhasi yethopholoji LAN:

• sibangelwa omnye iikhompyutha basekuhlaleni akusayi kuchaphazela ukusebenza nabanye oomatshini kunye nothungelwano ngokubanzi;
• loqwalaselo elula noyilo LAN;
• iindleko esiphantsi sexabiso consumables (kunye radius amancinci amanyathelo, umzekelo, phakathi umbutho efanayo).

Ububi yethopholoji:

• Cable umonakalo ezivaliweyo uthungelwano jikelele;
• olungephi ulungiso kunye nabasebenzisi ezimbalwa;
• kwisantya elincinane ngokwentelekiso (kuxhomekeka kwinani kweekhompyutha kwi-network).

"Inkwenkwezi" ithopholoji

Le ithopholoji yale hlobo ibandakanya impefumlelwano iikhompyutha yendawo nge izixhobo womnatha (hub okanye hub) abonelela uqhagamshelwano engumzekelo koomatshini zokusebenza. kwisikhululo ngasinye oludityaniswe isixhobo host ngokusebenzisa ikhadi inethiwekhi yentambo eyahlukileyo. Njengoko ngendlela angaphambili ithopholoji, iinkcukacha ephumayo iyafumaneka kuzo zonke iikhompyutha kwi-network, kwaye ziya kwamkelwa kuphela ngumsebenzisi apho ke zenzelwe.

Benefits yethopholoji:

• lula ukuhlela umsebenzi omtsha;
• ukusebenza eliphezulu;
• iphutha fast okanye ikhefu intambo;
• kwi ukusebenza uthungelwano, azichatshazelwa isiphoso koomatshini bendawo ngamnye.

Ububi yethopholoji:

• ekungaphumelelini unit central eyeka umsebenzi womnatha yonke;
• inani labasebenzisi kuphelele inani namazibuko unit central;
• ukusetyenziswa nandlela in intambo;
• Ukufumana iindleko Hub (okanye ezinye izixhobo network).

Yethopholoji efanayo "ring"

ufakelo LAN leyo yenziwe ngokungqinelana nemithetho olu hlobo ithopholoji, kuba kuthotho koomatshini zokusebenza ezihambelanayo, bakha ngomsesane. Idatha kulo mzekelo zivela kwikhompyutha omnye komnye, kwaye bemiyo phezu yokuba ziyalungiswa.

Izinto eziluncedo yethopholoji efanayo "ring":

• Akukho zindleko yezixhobo womnatha (hub, umzila);
• ukukwazi ukudlulisela ulwazi phakathi iikhompyutha ezininzi ngaxeshanye.

Ububi yethopholoji:

• nokwenziwa komsebenzi womnatha opheleleyo kuxhomekeke kwisantya kwikhompyutha nganye;
• Ukwahlukana cable okanye ukusilela ikhompyutha itshixiwe ukusebenza kulo lonke uthungelwano;
• ukuntsonkotha yocwangciso kunye uqwalaselo;
• Umbutho kwemisebenzi emitsha ngexesha amanzi umsebenzi LAN.

Le ithopholoji le "ring" phantse akaze asetyenziswe practice ngenxa ukungakhuseleki jikelele, kodwa kuxhomekeke zokuguqulwa ezahlukeneyo.

Okwangoku, phantse akukho mbutho unako ukuyenza ngaphandle LAN. Kwande "inkwenkwezi" inethwekhi yethopholoji ngenxa ukuthembeka kunye isiphoso nokunyamezelana. LAN yethopholoji efanayo "ring", ngokuchaseneyo, musa ukuhlangabezana zezempilo nezokhuseleko mihla. Nangona kunjalo, i-LAN baye babe yinxalenye yobomi bethu negalelo ekuphumeleleni naliphi na ishishini.
