Bhanqa amanethiwekhi amabili wendawo wendawo ukuthi asebenze njengenethiwekhi eyodwa
Ibhuloho yenethiwekhi ijoyina amanethiwekhi amabili ahlukile ekhompyutheni ukuze akwazi ukuxhumana phakathi kwabo futhi avumele ukuthi basebenze njengenethiwekhi eyodwa. Amabhuloho asetshenziselwa amanethiwekhi wendawo (LANs) ukukhulisa ukufinyelela kwawo ukuze afake izindawo ezinkulu ezingaphezu kwe-LAN engafinyelela. Amabhuloho afana nokunye okunye okuhlakaniphile kunokuphindaphinda okulula, okwandisa ibanga lesignali.
Ukusebenza Kwamabhulogi Okusebenza Kanjani
Amadivaysi amabhuloho ahlola ithrekhi yenethiwekhi engenayo futhi anqume ukuthi angayithumela noma ayilahle ngokuya endaweni ehlosiwe. I-Bridge ye- Ethernet , isibonelo, ihlola uhlaka lwe-Ethernet ngayinye engenayo kufaka phakathi amakheli e-MAC ovela kumthombo nendawo okuya kuyo-ngezinye izikhathi ubukhulu befreyimu-uma wenza izinqumo zokudlulisela ngabanye. Amadivaysi amabhuloho asebenza ekubhekeni kokuxhumanisa kwedatha yesimo se- OSI .
Izinhlobo zamabhulogi wenethiwekhi
Amadivaysi eBridge akhona kwi-Wi-Fi ku-Wi-Fi, i-Wi-Fi kuya ku-Ethernet, ne-Bluetooth ku-Wi-Fi ukuxhumana. Ngamunye wenzelwe izinhlobo ezithile zokuxhumana.
- Amabhuloho angenantambo angeseka amaphuzu wokufinyelela okungenazintambo ze-Wi-Fi.
- Ama-bridge e-Wi-Fi e-Ethernet avumela uxhumano kumaklayenti e-Ethernet futhi abhekise kubo kwinethiwekhi yendawo ye-Wi-Fi, ewusizo kumadivayisi asekudala anethiwekhi angenayo ikhono le-Wi-Fi.
- I-Bluetooth kuBhuloho ye-Wi-Fi isekela uxhumano namadivaysi e-Bluetooth eselula ekhuphuke emakhaya nakumahhovisi eminyakeni yamuva.
Ukukhishwa okungenantambo
Ukwakheka kudume ngokukhethekile kumanethiwekhi wekhompuyutha we-Wi-Fi . Ku-Wi-Fi, ukukhishwa okungenantambo kudinga ukuba amaphuzu wokufinyelela axhumane nomoya okhethekile osekela ithrafikhi egeleza phakathi kwabo. Amaphoyinti amabili okufinyelela asekela imodi yokubhanqa engenantambo esebenza njengombhangqwana. Ngamunye uyaqhubeka nokusekela inethiwekhi yakhe yendawo yamakhasimende axhunyiwe ngenkathi ehlanganisa nokunye ukubhekana nomgwaqo we-bridging.
Imodi yokudonsa ingasetshenziswa kuphuzu lokufinyelela ngokusebenzisa ukuhlelwa kokuphatha noma ngezinye izikhathi inkinobho yomzimba eyunithi. Akuwona wonke amaphuzu wokufinyelela asekela imodi yokubhangqa engenantambo; thintana nemibhalo yomkhiqizi ukuze unqume ukuthi imodeli enikeziwe isekela lesi sici.
Amabhuloho ngokuphindaphindiwe
Amabhulogi nabasebenzisi be-network bahlanganyela ngokubonakala ngokomzimba okufanayo; ngezinye izikhathi, iyunithi eyodwa yenza imisebenzi emibili. Ngokungafani namabhuloho, noma kunjalo, abaphindaphindiwe abenzi noma yikuphi ukuhlunga kwezimoto futhi ungajoyina amanethiwekhi amabili ndawonye. Esikhundleni salokho, abaphinda baphinde badlulise yonke imoto abayitholayo. Ukuphinda kubambelela kusebenza ngokuyinhloko ukuvuselela izimpawu zomgwaqo ukuze inethiwekhi eyodwa ingakwazi ukufinyelela amabanga omzimba angaphezulu.
Amabhuloho vs. Ama-Switches nama-Routers
Emanethiwekhi wekhompuyutha anezintambo, amabhuloho asebenza ngendlela efanayo nokushintsha kwenethiwekhi . Ngokwesiko, amabhuloho anezintambo asekela uxhumano olulodwa olungenayo nolunye oluphumayo lwenethiwekhi, olufinyeleleka nge- port hardware , kanti izitshalo ngokuvamile zinikeza amathole amane noma ngaphezulu hardware. Ngokuvamile ama-switches abizwa ngokuthi amabhuloho we-multiport ngalesi sizathu.
Amabhuloho ayinakho ukuhlakanipha kwezinethiwekhi zenethiwekhi: amabhuloho awaqondi umqondo wamanethiwekhi okude futhi angeke akwazi ukuthumela imilayezo ezindaweni ezehlukene kodwa kodwa esikhundleni sokusekela isikhombikubona esisodwa ngaphandle.
