Kutheni ufuna uneswitshi ephethwe

Umgaqo yokusebenza kothungelwano computer ukudibanisa ezahlukeneyo izixhobo (iikhompyutha zobuqu, neuropathy izixhobo) kwinkqubo enye ezinamacandelo iintsimbi nje ezimbini: imizila yesinye isitshixo. Ngokusebenzisa izixhobo ezinjalo, zonke izinto womnatha uyakwazi ukunxibelelana nabanye kunye nezinye iinethiwekhi. Ngaphandle, i iiswitshi kunye imizila khangela efanayo, kodwa kufuneka imisebenzi eyahlukeneyo. Kweli nqaku liza siya kugxininisa kwisixhobo okokuqala, yaye ezinjalo uzahlule ifomu njenge iswitshi ephethwe. Ngoko ke, olunjani kwezixhobo?

Injongo neendidi eyenziwayo

Ezi zixhobo zisetyenziselwa ukwakha uthungelwano ngaphakathi kwisakhiwo esinye okanye kwindawo ethile. Le nokucima ukuqhagamshela PC, iiseva, abashicileli, yabavavanyi, lonto iyakuvelisa uthungelwano lwemvelaphi eyahlulwayo. izixhobo ezifana ongasebenza njenge umlawuli, oko kukuthi ukuvumela izinto ezahlukeneyo ukunika ufikelelo kulwazi, kwaye basebenzisane kunye nabanye abathathi-nxaxheba. Ngokubonelela loo ukufikelela data kunye nokwabiwa kwezibonelelo, ukuphucula ukusebenza zokucofa ye-network.

Kukho iindidi ezimbini zixhobo: ilawulwe olungalawulwayo. umsebenzi lwakutshanje kwi template standard. Umsebenzisi akakwazi ukwenza utshintsho kuyo. Xa ekhaya networks wagqiba ukusebenzisa olu hlobo. Tshintsha ephethwe ivumela ukufikelela kweenkqubo. Ngenxa le mfanelo, ithi iqinisekise bhetyebhetye eliphezulu le nkqubo. Oku kungenxa yokuba utshintsho ezilawulwa nga abaqwalaselweyo esweni kude okanye ekuhlaleni ulawulo lwezithuthi womnatha kunye nokufikelela kuyo. Makhe sihlolisise ngokweenkcukacha olu hlobo kwezixhobo.

Tshintsha elawulwa: iimpawu zobugcisa

izixhobo ezinjalo iyakwazi ukuxhasa iimpawu ezininzi ezahlukeneyo ukwenza utshintsho nezicwangciso zecebo lo. Umsebenzisi uqhagamshela kwisixhobo omnye cantilever okhokelayo kwaye usebenzise cli ukuqwalasela umsebenzi kwefowuni. Ukongeza, isixhobo ungalawuleka ugqitha i SNMP, Telnet, SSL kunye SSH. A iswitshi ezilawulwa iyakwazi ukuxhasa imisebenzi ephambili (RSTP, MSTP, STP), ukuba womnatha (phakathi izixhobo kunye neekhompyutha) kukho iindlela ezimbini okanye ngaphezulu. Ukuba umsebenzisi kufuneka zibethelele umgangatho wokhuseleko womnatha, ungabeka okhethekileyo umsebenzi 802,1 X, ACL. Aphethwe iintlobo switch, ngokuxhomekeke msebenzi, iyakwazi ukuxhasa VLAN ezininzi. izixhobo ezinjalo zinganika ukuthembeka ophezulu kunye nozinzo lothungelwano computer.

isiphelo

Uphuhliso ayikho izixhobo kwindawo womnatha. Kule mboni, kukho kusoloko iingcinga ezintsha. Ezinye zazo zenzelwe ukuba ukudala uthungelwano icomputer usebenzisa i kweentambo zekopolo, ngoxa abanye - kuba ngenxa lothungelwano technology fibre-optic. Ngokufanayo, ngokukhawuleza kakhulu kwaye siye saxubusha icebo. Umzekelo, uyakwazi ukubona kwinethiwekhi yekhompyutha, elawula kulawulwa Inqanaba utshintsho-2 okanye ezi-3. Ukuthandwa izixhobo kungenxa computerization ngokubanzi, kuba ngoku idityaniswe zibe kwinkqubo yemfundo engabandakanyi zeefoni, nomabonwakude, kunye intanethi, nkqu inethiwekhi ebhankini.
