Ugqithiselo nge iintambo data Ethernet kwaye ngaphandle

transmission Data phezu womnatha uquka ezininzi izixhobo zonxibelelwano oludibanisa imijelo data, yaye isixhobo ziguquka phakathi yonke imiyalezo endpoints exchange.

Phakathi computer, umzekelo, iinkcukacha ezikhutshelwa qho kwaye kwenziwa ngokungqinelana neemfuno zabantu abasebenza ukuba PC. Zizixhobo ingaba cwaka ixesha elide, besebenza ngokuzimeleyo (transfer data singàphunyezwa ngeli xesha), yaye emva koko wathumela ndaweni umyalezo okanye uxwebhu. Xa nesezantsi isantya yomnxeba channel, le fayile iya kudluliselwa kangangemizuzu eliqela, yaye ngokufuthi ndiyacaphuka abasebenzisi. Ukuze ukususa bajonga iingxaki womnatha sele iphuhlisiwe, esebenzisa i-high speed intambo ofanayo zonke izixhobo. Asiyi bachukumise phezu iinkcukacha zobugcisa apha, kwaye singatsho kuphela ukuba womnatha enjalo zimelwe ngohlobo iikhompyutha oqhagamshelwano phakathi, nganye elandela isitishi. Kwimeko of transfer ye computer ivumela idilesi, kwaye umntu lowo yena, wamkela ulwazi. Ukuba kuyimfuneko, ukutshintshela umsebenzisi ethile kufuneka alinde ukuze kukhululwe ijelo, uze uqalise ukudluliswa. Ukuba kuyenzeka ukuba abasebenzisi ezimbini ngaxeshanye uzame ukumbamba umgca, ngoko emva kokuba ingasebenzi ixesha elifutshane, zama kwakhona de omnye kubo phambi enye. Ngubani wathabatha eqhelekileyo computer ejelo yisebenzise ngesantya ngokupheleleyo ngokupheleleyo. Le algorithm kakuhle kakhulu intsebenziswano apho ugqithiselo lweengcombolo akakhawulezi nethembekileyo.

Njengokuba mhlawumbi sele ugqibe ekubeni olu hlobo womnatha igama Ethernet. Sebenzisa iintlobo zonxibelelwano kwindawo encinane, ezifana ngaphakathi kwisakhiwo. Ngoko ke uhlobo yokudityaniswa yasekuhlaleni. Uthungelwano Ethernet ikumgangatho ngamazwe yaye wathabatha phantse yonke kwimarike sezwe ingxenye yayo.

Radio-Ethernet lwaphuhliswa ngakumbi kutshanje. Lo mgangatho entsha, kwaye isebenzisa ezimbini. Okokuqala, le ndawo yendawo zintambo network phakathi kweendonga kwisakhiwo okanye kwizakhiwo. It elisombulula ingxaki 'ukuhamba limited "phakathi umbutho - bonke abasebenzi bayakwazi ukufikelela kwinethiwekhi ezikumgangatho ophezulu. Okwesibini, Radio-Ethernet connectivity likuvumela ukuba wenze i ingxaki ukuya kuthungelwano enkulu lwababhalisi, kunye nokudluliselwa data zobuqu lwenziwa indiva ngxaki imayela lokugqibela. Igama elithi "imayela yokugqibela" lisetyenziswa nokumisela uqhagamshelwano phakathi yababhalisi kunye ikufutshane oko esiludumbo "uthungelwano enkulu." Umgama enyanisweni ziyahluka ukusuka iimitha ezimbalwa ukuya leekhilomitha 20-30.

Bekungalunganga ukuba kuziswe yababhalisi radio nganye "indawo ukuze aveze", ngenxa yokuba kulo mzekelo, ngenxa yezizathu zeteknoloji, ijelo uya kuba imali eninzi, yaye ingcaciso ampontshwe kancinane. Ngoko ke lusebenza kakhulu ukuba amalungiselelo ijelo "point-to-ezininzi" kwaye wenze ifumaneke kwababhalisele ngaphezulu. Ezi ababhalisele Ungayisebenzisa kwimowudi yokungqubana, ezifana inethiwekhi Ethernet. Esi sigqibo wayezelwe kwaye ziphuhliswe kutsha nje, kwaye uyahambisana eqhelekileyo Ethernet-USB. Radio-Ethernet IEEE kutshanje wafumana iKomiti International, kwaye ubonelela uzinzo lobugcisa yomsebenzi zokusebenza.
