Ngaphambi kokuqonda umsebenzi wokuhlukanisa we-VLAN weswishi, siqale siqonde iswishi ye-Ethernet: Iswishi ye-Ethernet iyiswishi esekelwe ekudlulisweni kwedatha ye-Ethernet. Imbobo ngayinye yeswishi ye-Ethernet ingaxhunywa kumsingathi, ngokuvamile isebenze ngemodi ye-duplex egcwele,...

I-Optical fiber transceiver iyithuluzi lokuguqula i-photoelectric eliguqukayo nelisebenzayo elidlala indima ebalulekile ku-multi-protocol photoelectric hybrid LAN. Manje, ukuze kutholwe kangcono futhi kuqedwe amaphutha esixhumanisi, amanye ama-transceivers efiber optical anesixhumanisi esihlulekayo (...

I-VLAN (i-Virtual Local Area Network) ibizwa ngesiShayina. I-VLAN ihlukanisa i-LAN ebonakalayo ibe ama-LAN amaningi anengqondo, futhi i-VLAN ngayinye iyisizinda sokusakaza. Ababungazi ku-VLAN bangakwazi ukuxhumana nemilayezo ngemodi yokuxhumana ye-Ethernet evamile, kodwa phakathi kwababungazi ku...

Ngokuxhumana optical, ukuhlola amandla optical isinyathelo esibalulekile ekwakheni imvelo optical. Izinga lamandla okubona lithinta ukusebenza kwedivayisi eyamukelayo. Amandla okukhanya aphansi kakhulu azokwenza idivayisi ingakwazi ukukhonjwa, nokukhanya okuphezulu kakhulu ...

Ngenxa yentuthuko eminingi kanye nempumelelo yezobuchwepheshe ku-hardware efanelekile, isofthiwe, izivumelwano namazinga, ukusetshenziswa okusabalele kwe-VoIP kuzofezeka maduze. Ukuthuthuka kwezobuchwepheshe kanye nentuthuko kulezi zindawo kube nomthelela ekwakhiweni kwe ...

Ukuze kusetshenziswe izinhlelo zokusebenza ze-multimedia kunethiwekhi yokuxhumana ekhona, i-International Telecommunication Union (ITU-T) ithuthukise uchungechunge lwephrothokholi yokuxhumana ye-multimedia ye-H.32x. Okulandelayo incazelo emfushane yezindinganiso eziyinhloko H.320, ...
