I-LAN ithandwa kakhulu esiyisebenzisayo namuhla.Yini i-LAN?
I-Local Area Network (LAN) ibhekisela eqenjini lamakhompyutha axhunywe amakhompyutha amaningi endaweni ethile asebenzisa isiteshi sokusakaza.Uma kuningi kule ndawo, kulapho amathuluzi amaningi akwazi ukuxhumana.Futhi yi-LAN yohlelo kuphela engaxhumana.Isibonelo, okokusebenza kwekhompyutha ku-LAN yeswishi efanayo kungaxhunywa ngekheli le-MAC.
I-LAN inezici eziningi, okuyenza ibe ngenye yezindawo ezijwayelekile:
Isici 1: Uhla lokuxhuma lwe-LAN luncane kakhulu, futhi luxhunywe endaweni yendawo ezimele kuphela, njengebhilidi noma iqembu lesakhiwo esimaphakathi.Kungaqondwa ukuthi amakamelo esakhiweni esifanayo angaxhunywa komunye nomunye ngamakheshi.
Isici sesi-2: I-transmission medium (ipheya esontekile, ikhebula eliqinile) ebekwe ngokukhethekile isetshenziselwa ukuxhumana nenethiwekhi, futhi izinga lokudluliswa kwedatha liphezulu kububanzi obungu-10Mb/s kuya ku-10Gb/s.Isibonelo, ohlelweni oluzimele, kungakhathaliseki ukuthi ukuya emakamelweni ahlukene noma ukufinyelela amakamelo ahlukene ngekheshi kusetshenziswa.Ihlobene nesakhiwo sehadiwe yesixhumi esibonakalayo senethiwekhi esisetshenzisiwe.
Isici sesi-3: Ukubambezeleka kokuxhumana okufushane, izinga lephutha elincane, nokuthembeka okuphezulu.
Isici sesi-4: Zonke iziteshi ziyalingana futhi zabelana ngesiteshi sokudlulisa.
Isici sesi-5: Isebenzisa ukulawula okusabalalisiwe nokuxhumana kokusakaza, futhi ingasetshenziselwa kokubili ukusakazwa nokusakaza okuningi.
Izinto eziyinhloko ezakha i-LAN i-topology yayo yenethiwekhi, imidiya yayo yokudlulisela, nezindlela zayo zokulawula ukufinyelela kwabezindaba.
Okungenhla incazelo yolwazi yokuqonda kokuqala kwe-LAN elethwa i-Shenzhen HDV Phoelectron Technology Co., Ltd., umkhiqizi wemishini yokuxhumana ebonakalayo.
