Iyiphi ikhebhu kwaye isebenza njani?

I-hub yimbono ebanzi. Akusetyenziswanga kuphela kwisigama sesicatshulwa. Kwakhona, umzekelo, kukho imbono ye- hub ye- USB. Le sixhobo, leyo Isetyenziselwa ukudibanisa iidivaysi ezahlukeneyo ze-USB kwelinye port. Kodwa oku akusilo lonke uluhlu lwamathuba okusebenzisa i-concentrators yemvelo eyahlukileyo.

Kwiphina iprojekti ephuhlisayo kwicandelo leemarike yolwazi, kungekudala okanye kamva, umsebenzi uhlanganiswa ukudibanisa inani elithile leenkcukacha zokucwangcisa idatha. Lo msebenzi unokuqulunqwa kalula ngethungelwano elenziwe kakuhle. Ukuphumeza lo msebenzi, kukho ubuninzi bezobuchwepheshe obuninzi. Ukuqala ukucwangcisa ukwakhiwa kwenethiwekhi yakho, kufuneka ukhawuleze uqinisekise ukuba zeziphi iifowuni zokuhlanganiswa kweenkcukacha ezihambayo ziya kusetyenziswa kwinkqubo yokugcina impilo yokunxibelelana kwenethiwekhi. I-network hub (hub) yenye yezixhobo.

Uphawu oluphambili lwendlela yokutshintsha i-hub eneenkcukacha zayo ngokuphawulekayo ekuguquleleni imifudlana yedatha. Zonke izibuko zinamalungelo afanayo. Ngoko ke, xa ufumene umyalezo wolwazi kumnye wabo, unikezela ukuguqulela kuwo onke amanye amachweba asebenzayo. Ukuthetha ngokuthe ngqo, ukuze uqonde ukuba yeyiphi i-hub, kufuneka uqonde oko. Le phinda liye lenzelwe inani elikhulu leechweba kwaye linomsebenzi osebenzayo wokuzibandakanya ngokwasemzimbeni. Ukulungiswa komsebenzi yinkqubo yokulawula ngokuzenzekelayo izibuko eziphosakeleyo (inkqubo yokudluliselwa kwichweba eliphosakeleyo ivelisa enye inqubo-ukuvakalisa i-port engasebenzi). Kwixesha elizayo, ukuba iphoso liphelile, i-port iyasebenza kwakhona.

Yiyo impendulo kumbuzo wento ye-hub kunye nendlela ihluke ngayo kumtshintsho. Iipropati ze-network hub zinokunyusa kakhulu inqanaba elipheleleyo lokunyaniseka nokunyamezela ukuxhomekeka kwenethiwekhi. Ngaphezu koko, isisombululo sazo zonke iintambo eziye zavela kunye nokuqinisekisa ukuba ulawulo jikelele ngokubhekiselele kwisimo seendlela ezixhunyiwe liphathiswe ngqo kwisixhobo ngokwawo ngaphandle kokusetyenziswa kwamanqanaba angaphezulu, zombini iprojekthi kunye neofthiwe.

IiHubs zingadibaniswa kunye, ezikuvumela ukuba wakhe amanethiwekhi ngokupheleleyo naluphi na ubukhulu kunye nobukhulu. Kananjalo bavumela ukuxhamla kwetr phakathi komnye, ngoko kuqinisekisa ukuphunyezwa kwe-topology ye "ibhasi". Kodwa i-concentrators ineyona nto ebaluleke kakhulu: kuxhomekeka kakhulu kwi- topology ye-intanethi apho isetyenziswe kuyo, oko kukuthi, ayinayo yonke into. Ngoko, kwi-topology nganye, iindidi zazo ze-concentrators ziveliswa.

Ngokubanzi, ukwenzela ukuba ekugqibeleni uqonde ukuba yeyiphi ihabhu, kuyimfuneko ukuqonda into enye: kukuvumela ukuba udibanise iifowuni zomntu eziyingxenye yenethiwekhi kwiqela elilodwa lomhlaba (okanye, ngokuchanekileyo, lendawo).

Sazama ukuqonda ngokubanzi ukuba yeyiphi intsimbi kunye noko kudliwa ngayo. Ubuninzi bomsebenzi kunye nokusetyenziswa okubanzi kwenza abagxininisi basetyenziswe ngokubanzi kwiimveliso zeteknoloji yolwazi lwanamhlanje. Ngoncedo lwabo, unokuyicombulula imisebenzi eyinkimbinkimbi yokwakha amanethiwekhi ekhompyutha kwaye kungekhona kuphela.
