Kuchinjirwa Via Ethernet date netambo uye wirelessly

Data Kupfuudzwa pamusoro pomumbure rinosanganisira muzvizhinji pakukurukurirana namano kuti nokubatanidza mashoko hova, uye nokuchinja mudziyo inopiwa pakati zvose endpoints chinjanai mashoko.

Pakati pachavo makombiyuta Somuenzaniso, mashoko yedzimudzangara iri pamutemo uye kunze maererano zvinodiwa vanhu kushanda kuti PC. The mano zvinogona ndakanyarara kwenguva refu, kushanda vakazvimiririra (date kuchinjirwa haina kuitwa panguva ino), uye akatuma kumwe shoko kana gwaro. Kana low-nokukurumidza runhare mugero, faira ichi chichange kutapuriranwa kwemaminitsi anoverengeka, uye kakawanda Zvinondisvota vanozvishandisa. Kubvisa nechinouya kwakadaro rezvebonde yambokurukurwa, iyo inoshandisa vanowanzochema mukuru-nokukurumidza wire kuti mano ose. Hatidi kubata pamusoro zvekushandisa mashoko pano, uye tinogona chete kutaura kuti yakadaro samambure inogona anomirirwa muchimiro interconnected makombiyuta, chimwe nechimwe inotevedzera chiteshi. Kana kuchinjwa kombiyuta anoona kero, uye munhu uyo unotaurwa, anogamuchira ruzivo. Kana zvakakodzera, uchatamisa yakananga User anofanira kumirira kusunungurwa gwara, uye ipapo kutanga kuchinjwa. Kana zvikaitika kuti vanoshandisa maviri panguva imwe chete akaedza kubvuta mutsetse, shure kuva simbe kwenguva pfupi nguva, edza zvakare kusvikira mumwe wavo pamberi mumwe. Ndiani akatora chimwe chiteshi kombiyuta anogona kurishandisa panguva akurumidze uye azere. Uyu vakarongeka chaizvo algorithm kuti kushanda umo mashoko kuchinjirwa iri kutsanya uye hwakavimbika.

Sezvo imi pamwe kare wafungidzira, ichi mhando samambure ndiro Ethernet zita. Shandisa zvakafanana mhando kukurukurirana imwe nzvimbo diki, zvakadai mukati chivakwa. Saka munhu munharaunda kubatana mhando. An Ethernet samambure iri kwezvipimo pose uye akatora zvinenge zvose kumusika nyika racho chidimbu.

Radio-Ethernet yakazokudziridzwa nguva ichangopfuura. mureza itsva iyi, uye chine tizvishandise maviri. Chekutanga, ndiko Wireless omunharaunda nzvimbo samambure mukati mamasvingo rechivako kana dzinoita. Anogadziriswa chinetso "zvava kundiomera kufambisa muviri" mukati sangano - vashandi vose kuwana yepamusoro Network. Chechipiri, Radio-Ethernet connectivity unokubvumira vakwanise dambudziko kune hombe richikurukura subscribers, uye kuchinjwa pachake mashoko rinoitwa pavaigona kutora chikepe chaienda wokupedzisira maira dambudziko. Shoko rokuti "wokupedzisira maira" rinoshandiswa kusarudza connectivity pakati rinotengeswa nevaridzi uye pedyo nayo raiva pedyo nebundu "guru network." Daro zvechokwadi kunogona anosiyana kubva metres shoma kusvika 20-30 makiromita.

Hazvina kukodzera kuti mumwe rinotengeswa nevaridzi redhiyo "anotaura kunongedzera", nokuti iyi, nokuti kwezvinhu zvikonzero, gwara achava zvinodhura, uye mashoko zvichabviswa pumped zvishoma nezvishoma. Saka zviri zvikuru inoshanda kuronga gwara "pfungwa-kuti-multipoint" uye kuti chiwanikwe yakawanda subscribers. subscribers izvi anogona kurishandisa ari kudhumhana muoti, zvakadai somunhu Ethernet Network. Chisarudzo ichi agamuchirwa uye vakava chete yapfuura, uye inowirirana nemashoko kwakajairika Ethernet-waya. Radio-Ethernet mureza IEEE ichangopfuura vakagamuchira International Committee, uye rinopa hwokugadzira kutsiga operative basa.
