Ingcamango yeVLAN (i-LAN ebonakalayo)
Sonke siyazi ukuba kwi-LAN enye, uxhulumaniso lwehabhu luya kudala i-domain yengxabano. Ngelixa phantsi kokutshintsha, i-domain yengxabano ingasonjululwa, kuya kubakho indawo yosasazo. Ukuze ucombulule lo mmandla wosasazo, kuyimfuneko ukwazisa ii-routers ukwahlula iiLAN ezahlukeneyo kwiintlobo ezahlukeneyo...Funda ngokugqithisileyo - NguMlawuli / 28 Oct 22 /0Amagqabantshintshi
Ukwahlukaniswa kwe-LAN
Kwinkqubo yokuhanjiswa kwenethiwekhi, ukuba zonke ii-hubs zisetyenziswa. Kuqinisekile ukuba kwinkqubo yothumelo, kuba imiqondiso emininzi kufuneka isasazwe, i-domain yongquzulwano iya kuveliswa. Ngeli xesha, unxibelelwano phakathi kwemiqondiso luya kuphazamiseka kakhulu, kwaye izixhobo kwi-s...Funda ngokugqithisileyo - NguMlawuli / 27 Oct 22 /0Amagqabantshintshi
I-ONU's LAN (inethiwekhi yendawo yendawo)
