Kuyini ihabhu ukuthini futhi kusebenza kanjani?

Hub - umqondo ubanzi kakhulu. Isetshenziselwa hhayi kuphela amagama inethiwekhi. Futhi, isibonelo, lapho umqondo isikhungo se-USB. Le divayisi, okuyinto Isetshenziselwa ukuxhuma embobeni eyodwa ezintweni eziningi ezahlukene USB-kumadivayisi. Kodwa lokhu akulona lonke uhla ngamathemba kwesicelo concentrators bemvelo ezahlukene.

Ekuthuthukiseni iyiphi inkinga okusalungiswa kwenzeka ngokushesha noma kamuva ingxenye Imininingwane ukuhlanganisa inani elithile bahlukane idatha ukucutshungulwa amadivaysi. Le nkinga kalula ixazululwe inethiwekhi esakhiwe kahle. Ukuqalisa lo msebenzi, kukhona eziningana impela ubuchwepheshe. Saqala ukuhlela ukwakhiwa inethiwekhi yayo, kufanele ngokushesha linqume ukuthi ulwazi ukugeleza amadivayisi sizosetshenziswa inqubo nokugcina operability we noxhumo lenethiwekhi sesisonke. Ihabhu inethiwekhi (ihabhu) - ingenye mishini.

The main lolwehlukanisa inkinobho, okuyinto has a ihabhu - ke isici yezokusakaza idatha ukusakaza. It has lonke nezimbobo banamalungelo afanayo. Ngakho-ke, ulwazi flow etholwe omunye wabo, inikeza ukusakaza yayo zonke ezinye izimbobo asebenzayo. ukukhuluma Cishe, ukuqonda ukuthi yini ihabhu, kubalulekile ukuqonda essence yayo. Lokhu repeater eyenzelwe inqwaba nezimbobo nokuba wusizo umsebenzi avtosegmentatsii. Avtosegmentatsiya - Ukuhlola kuyinqubo ukuzilawula ngokuzenzekelayo echwebeni ethintekile (ukudluliselwa port kuhlulekile kuphakamisa omunye inqubo - simemezelo port asisebenzi). Esikhathini esizayo, uma iphutha isuswe, echwebeni futhi iba imodi esebenzayo.

Lona impendulo yombuzo othi lokho ihabhu nokuthi ihluke inkinobho. Izakhiwo ihabhu inethiwekhi kungaba ngokuphawulekayo ngcono izinga jikelele nokwethenjelwa inethiwekhi nokuqina. Ngaphezu kwalokho, ukuthi ikhambi zonke ezivukayo izingxabano futhi ukuqinisekisa ukulawula inani phezu isiteshi isimo lobulungu inikezwa ngqo kudivayisi uqobo ngaphandle izindawo ezengeziwe, kokubili software kanye hardware.

Izizinda zingahlanganiswa nomunye, ukuvumela ukwakha topologies zenethiwekhi kanye ngokuphelele yimuphi usayizi. Futhi bavumela uxhumano phakathi umgogodla, kanjalo nokufaka yomphindwa "isondo". Kodwa Izikhumulo ube ethile enkulu: bancike kakhulu ku le yomphindwa inethiwekhi, lapho kudingeka khona, okungukuthi, akuzona jikelele. Ngakho, izinhlobo Izikhumulo ziyatholakala yomphindwa ngamunye.

Ngokuvamile, ukuze ekugcineni ukuthola ukuthi ihabhu, lowo muntu udinga ukuqonda - ivumela ukuba sihlanganise idivayisi ngayinye okuqondene inethiwekhi zibe munye (kunalokho sendawo) iqembu ukusebenza emhlabeni jikelele.

Siye sazama ukuqonda Imibandela lokho ihabhu futhi "lokho ibadla." Ukuba yizinhlobonhlobo kanye nokusebenza ezibanzi ukwenza Izikhumulo chithi saka Kwimakethe IT. Ngosizo lwabo kungenzeka ukuxazulula nezinselelo ukwakhiwa amanethiwekhi computer , hhayi kubo kuphela.
