I-LAN yeyona nto idumileyo esiyisebenzisayo namhlanje. Yintoni iLAN?
Inethiwekhi yeNdawo yeNgingqi (LAN) ibhekisa kwiqela leekhompyuter ezidityaniswe ziikhompyuter ezininzi kwindawo ethile zisebenzisa ijelo losasazo. Okukhona kukho kule ndawo, kokukhona izixhobo ezikwaziyo ukunxibelelana omnye komnye. Kwaye kuphela i-LAN yenkqubo enokunxibelelana. Umzekelo, izixhobo zekhompyuter kwi-LAN efanayotshintshainokudityaniswa ngedilesi ye-MAC.
I-LAN ineempawu ezininzi, iyenza ibe yenye yezona ziphambili:
Uphawu lwe-1: Uluhlu lokudibanisa lwe-LAN luncinci kakhulu, kwaye ludibaniswe kuphela kwindawo yendawo ezimeleyo, njengesakhiwo okanye iqela lokwakha eliphakathi. Kunokuqondwa ukuba amagumbi kwisakhiwo esifanayo anokudibaniswa omnye komnye ngokusebenzisa i-elevators.
Uphawu lwe-2: I-transmission medium (i-twisted pair, i-coaxial cable) ebekwe ngokukodwa isetyenziselwa ukunxibelelana, kwaye izinga lokudluliselwa kwedatha liphezulu kwi-10Mb / s ukuya kwi-10Gb / s. Ngokomzekelo, kwinkqubo ezimeleyo, nokuba uhamba ukuya kumagumbi ahlukeneyo okanye ukufikelela kumagumbi ahlukeneyo nge-elevator kusetyenziswa. Inxulumene noyilo lwehardware yojongano lwenethiwekhi olusetyenzisiweyo.
Uphawu lwesi-3: Ukulibaziseka konxibelelwano olufutshane, izinga lempazamo encinci, kunye nokuthembeka okuphezulu.
Uphawu lwesi-4: Zonke izitishi ziyalingana kwaye zabelana ngejelo lothumelo.
Uphawu lwesi-5: Isebenzisa ulawulo olusasazwayo kunye nonxibelelwano losasazo, kwaye ingasetyenziselwa zombini ukusasaza kunye nokusasazwa kobuninzi.
Izinto eziphambili ezenza i-LAN yi-topology yayo yenethiwekhi, i-media yayo yokuhambisa, kunye neendlela zayo zokulawula ukufikelela kumajelo.
Oku ngasentla yingcaciso yolwazi yokuqonda kwangaphambili kwe-LAN eziswa yi-Shenzhen HDV Phoelectron Technology Co., Ltd., umenzi wezixhobo zonxibelelwano zokukhanya.
