Ukuba usasebenzisa i-10 Mbps Ethernet, lixesha lokuphucula
I-version yokuqala yokuhlola ye- Intanethi ye- Intanethi ye- Intanethi yahamba ngesiqhamo sokuxhuma kwe-2.94 megabits ngesibini (Mbps) ngowe-1973. Ngexesha le-Ethernet yaba ngumgangatho woshishino ngo-1982, ukulinganisa kwantyawulo kwenyuka ukuya kwi-10 Mbps ngenxa yokuphuculwa kwitheknoloji. I-Ethernet igcinwe ngokukhawuleza kwesantya seminyaka engaphezu kwe-10. Iifom ezahlukeneyo zenkqubo zibizwa ngokuba ziqala ngenani le-10, kubandakanya i-10-base2 kunye ne-10-baseT.
Fast Ethernet
I-teknoloji ebizwa ngokuba yi- Fast Ethernet yaqaliswa phakathi ne-1990. Yayithatha elo gama ngenxa yokuba imigangatho ye-Fast Ethernet isekela izinga eliphezulu lolwazi lwe-100 Mbps, ezili-10 ngokukhawuleza kune-Ethernet yendabuko. Amanye amagama aqhelekileyo kulo mgaqo omtsha aquka i-100-BaseT2 kunye ne-100-BaseTX.
I-Ethernet ekhawulezayo yayisetyenziswe ngokubanzi njengoko imfuneko yokusebenza kwe- LAN enkulu yaba yinto ebalulekileyo kwiiyunivesithi kunye namashishini. Icandelo eliphambili lempumelelo yalo likwazi ukuhlala kunye nokufakelwa kwenethiwekhi. I- adapters ye- intanethi yolu xwebhu yakhiwa ukuze ixhase i-Ethernet yendabuko kunye ne-Fast Ethernet. Ezi zi-adapters eziyi-10/100 ziqonda isantya sezithuthi ngokuzenzekelayo kwaye zilungelelanise iirhafu zolwazi ngokuxhomekeka.
Gigabit Ethernet Speeds
Njengoko i-Fast Ethernet ithuthukisiwe kwi-Ethernet yendabuko, i- Gigabit Ethernet iphuculwe kwi-Fast Ethernet, inika amazinga ukuya kuma-1000 Mbps. Nangona iingu-1000 ze-BaseX kunye ne-1000-BaseT zadalwa ngasekupheleni kweminyaka yama-1990, kuthatha iminyaka emininzi i-Gigabit Ethernet ukuba ifikelele kwi-large scale adoption ngenxa yeendleko zayo eziphezulu.
I-Gigabit Ethernet isebenza kwi-10,000 Mbps. Iinguqu eziqhelekileyo eziquka i-10G-BaseT zaveliswa ukususela kwiminyaka ye-2000. Ukudibanisa ngokucwangcisiweyo kwesi sivinyiso kwakunexabiso elifanelekileyo kuphela kwiindawo ezithile ezizodwa ezifana nekhompyutheni ephezulu kunye namanye amaziko eenkcukacha.
I-Gigabit Ethernet kunye ne- 100 yeGigabit Ethernet ubuchwepheshe bephantsi kophuhliso olusebenzayo iminyaka ethile. Ukusetyenziswa kwazo kokuqala kubaluleke kakhulu kumaziko amakhulu edatha. Ngexesha, i-100 Gigabit Ethernet ngokuqinisekileyo ayiyi kubuyiselwa indawo ye-10 Gigabit Ethernet kwindawo yokusebenzela kwaye ekugqibeleni-ekhaya.
I-Ethernet & # 39; s Isikhululo seMali esingafaniyo neSantya esona
Ukulinganiswa kwejubane kwe-Ethernet kugxeke ngenxa yokungakwazi ukusetyenziswa kweli hlabathi. Ngokufanayo nokulinganiswa kwamafutha ombane, ukulinganiswa kwezixhobo zokuxhunywa kwenethiwekhi kubalwa phantsi kweemeko ezintle ezingabhekiseli kwimihlaba esebenza ngokuqhelekileyo. Akunakwenzeka ukudlula ezi ziphumo zokukhawuleza njengoko zixabiso eliphezulu.
Akukho namnye ipesenti okanye i-formula engasetyenziselwa kwisilinganiselo esiphezulu sokukhawuleza ukuba ukuba uxhumo lwe-Ethernet luya kusebenza njani. Ukusebenza okwenene kuxhomekeke kwiimeko ezininzi, kubandakanywa ukuphazamiseka komgca okanye i-collisions ezifuna izicelo zokubuyisela imilayezo.
Ngenxa yokuba iiprotokholi zethungelwano zisebenzisa inani elithile lomthamo wenethiwekhi nje ukuxhasa izihloko zentloko, izicelo azikwazi ukufumana iipesenti ezingama-100 kuphela. Kwakunzima nakakhulu kwizicelo ukuzalisa uxhumano lwe-Gbps kunye nedatha kunokugcwalisa uxhumano lwe-10 Mbps. Nangona kunjalo, ngezicelo ezifanelekileyo kunye neepatheni zokunxibelelana, amaxabiso olwabakho afikelela kumaqondo angaphezu kwe-90 ekhulwini lobuninzi bexesha lokusetyenziswa kwexesha.
