Uma usasebenzisa i-10 Mbps Ethernet, sekuyisikhathi sokuthuthukisa
Uhlobo lokuqala lokuhlola lwe- Ethernet lwama-networking wired lwaluhamba ngesivinini sokuxhumeka kwe-2.94 megabits ngomzuzwana (Mbps) ngo-1973. Ngesikhathi i-Ethernet yaba yinkimbinkimbi yembonini ngo-1982, ukulinganiswa kwayo kwejubane kwanda ku-10 Mbps ngenxa yentuthuko kwezobuchwepheshe. I-Ethernet igcine lesi silinganiso sejubane iminyaka engaphezu kwengu-10. Amafomu ahlukene wezinga aqoshiwe aqalwa ngenombolo 10, kufaka phakathi i-10-Base2 ne-10-BaseT.
Fast Ethernet
Ubuchwepheshe obubizwa ngokuthi i- Fast Ethernet bubizwa nge-colloquially phakathi nawo-1990. Iqoqa lelo gama ngoba izindinganiso ze-Fast Ethernet zisekela isilinganiso esiphezulu sedatha ye-100 Mbps, izikhathi ezingu-10 ngokushesha kune-Ethernet yendabuko. Amanye amagama avamile kule nqubo entsha ihlanganisa i-100-BaseT2 kanye ne-100-BaseTX.
I-Ethernet Esheshayo yasetshenziselwa kabanzi njengoba isidingo sokwenza umsebenzi omkhulu we- LAN sagxila kakhulu emanyuvesi nasemabhizinisini. Isici esiyinhloko sempumelelo yaso yikho ikhono lokusebenzisana nokufakwa kwenethiwekhi okukhona. Amaphakheji e- inthanethi ejwayelekile yosuku akhiwe ukuze asekele kokubili i-Ethernet yendabuko kanye ne-Fast. Lezi zi-adapters ezingu-10/100 zizwa ijubane lomzila ngokuzenzekelayo futhi zilungise amazinga okuxhumeka kwedatha ngokufanele.
Isivinini se-Gigabit Ethernet
Njengoba nje i-Fast Ethernet ithuthukiswe ku-Ethernet yendabuko, i- Gigabit Ethernet ithuthukiswe ku-Fast Ethernet, inikeza amanani kufika ku-1000 Mbps. Nakuba izinguqulo ezingu-1000-BaseX kanye ne-1000-BaseT zakhiwe ngasekupheleni kweminyaka yama-1990, kuthatha iminyaka eminye i-Gigabit Ethernet ukuthi ifinyeleleke ngokukhululeka kwamanani ngenxa yezindleko zayo eziphakeme.
I-Gigabit Ethernet isebenza ku-10,000 Mbps. Izinguqulo ezijwayelekile ezihlanganisa i-10G-BaseT zenziwa kusukela ekuqaleni kuka-2000. Ukuxhuma okuxhunyiwe kule gejimane kwakungabi nengozi kuphela ezindaweni ezithile ezikhethekile njengekhompyutha ephezulu yokusebenza kanye nezinye izikhungo zedatha.
I-Gigabit Ethernet ne- 100 Gigabit Ethernet ubuchwepheshe bebuchwepheshe bokuthuthukiswa okwenziwe iminyaka ethile. Ukusetshenziswa kwabo kokuqala ngokuyinhloko kube izikhungo ezinkulu zedatha. Ngokuhamba kwesikhathi, 100 Gigabit Ethernet ngeke ngokungangabazeki ibe indawo engu-10 Gigabit Ethernet emsebenzini futhi-ekugcineni-ekhaya.
I-Ethernet & # 39; s Isivinini esikhulu se-Speed vs. Speed Speed
Ukulinganiswa kwejubane kwe-Ethernet kuye kwagxeka ngenxa yokuthi ayikwazi ukutholakala ekusetshenzisweni kwezwe langempela. Ngokufanayo nokulinganiswa kwezimoto zamagesi, ukulinganiswa kwejubane lokuxhumeka kwenethiwekhi kubalwa ngaphansi kwezimo ezihle ezingafaneli neze izindawo ezijwayelekile zokusebenza. Akunakwenzeka ukuthi udlulele lezi zilinganiso zejubane ngoba zilinganiso eziphezulu.
Ayikho iphesenti elithile noma ifomula elingasetshenziswa esilinganisweni esiphezulu sejubane ukubala ukuthi uxhumano lwe-Ethernet luzosebenza kanjani. Ukusebenza kwangempela kuncike ezintweni eziningi, kufaka phakathi ukuphazanyiswa komugqa noma ukushayisana okudinga izinhlelo zokusebenza ukuphinda uthumele imilayezo.
Ngenxa yokuthi izivumelwano zenethiwekhi zisebenzisa inani elithile lomthamo wenethiwekhi nje ukusekela izinhloko zeprotocol, izinhlelo zokusebenza azikwazi ukuthola amaphesenti angu-100 kuphela. Kunzima nakakhulu izinhlelo zokugcwalisa uxhumano lwe-10 Gbps nedatha kunokugcwalisa uxhumano lwe-10 Mbps. Kodwa-ke, ngezinhlelo zokusebenza ezifanele namaphethini wokuxhumana, amazinga wangempela wedatha angafinyelela ezingaphezu kwamaphesenti angama-90 esiphezulu sezinkathi phakathi nokusetshenziswa kwezinga eliphezulu.
