I-Gigabit Ethernet inxalenye yentsapho ye- Ethernet yokunxibelelana kwikhompyutha kunye nemigangatho yokunxibelelana. Umgangatho we-Gigabit Ethernet uxhasa iqondo eliphezulu lolwazi lwe-1 gigabit ngesibini (Gbps) (1000 Mbps).
Ekuqalekeni, abanye bacinga ukuphumeza i-gigabit ngesivinini nge-Ethernet kuza kufuna ukusebenzisa i- fiber optic okanye enye iteknoloji yekhebula yekhethelo. Nangona kunjalo, oko kuyimfuneko kuphela kumgama omde.
I-Gigabit Ethernet yanamhlanje isebenza kakuhle isebenzisa intambo yebhondi ephothiweyo (ngokukodwa, i-standard CAT5e kunye neCAT6 imigangatho yokubumba) efana ne-100 Mbps Fast Ethernet (esebenza ngaphezu kweCAT5 ). Ezi ntlobo zeekhebula zilandela i-1000BASE-T yokulinganisa i-standard (ebizwa ngokuba yi-IEEE 802.3ab).
Ukukhawuleza Kwenzeka Njani i-Gigabit Ethernet kwi-Practice?
Ngenxa yeziganeko ezinjenge- protokto yenethiwekhi kunye nokudluliselwa kwakhona ngenxa yeendlela zokungqubana okanye ezinye iingaphumeleli ezidlulileyo, izixhobo azikwazi ukuthumela idatha yesigidimi esiluncedo kwi-1 Gbps (125 MBps).
Ngokweemeko eziqhelekileyo, nangona kunjalo, ukuhanjiswa kwedatha efanelekileyo kwi-cable kungase kufike kuma-900 Mbps ukuba mhlawumbi kube ngamaxesha ambalwa.
Kwi-PC, i-disk drives inganciphisa kakhulu ukusebenza koxhumano lwe-Gigabit Ethernet. Iimoto ezinzima zomdabu zihamba ngeerhafu phakathi kwama-5400 kunye no-9600 ukuvuswa kwemigangatho yesibini, ezinokusingatha izinga lokudluliswa kwedatha phakathi kwama-25 kunye nama-megabytes angama-100 ngesibini.
Ekugqibeleni, ezinye ii-router zasekhaya kunye neechwethi ze-Gigabit Ethernet zinokuba ne-CPU ezingakwazi ukuphatha umthwalo ezifunekayo ukuxhasa ukufika kwedatha engenayo okanye ephumayo kwiirhafu ezipheleleyo zoxhumo lwenethiwekhi. Izixhobo ezingakumbi zabaxhasi kunye nemithombo efanayo yomnxeba we-intanethi, ubuncipheko obuncinane kwiprojekter yomqhubi ukuze bakwazi ukuxhasa ukuhanjiswa kwejubane ngokukhawuleza kunxibelelwano oluthile.
Kukho umbandela wokukhawulela umda wokuqhagamshela ukuxhomekeka kubakho nangona ukuba inethwekhi yonke yekhaya ingafumana ukukhawuleza kwee-1 Gbps, nokuba zidibaniso zombini zangexeshana zikhawuleza i-bandwidth ekhoyo yezixhobo zombini. Kuyafana nawaphi na manani amadivaysi ahambelanayo, anjengobuhlanu abahlula i-1 Gbps kwiinqununu ezintlanu (200 Mbps nganye).
Indlela yokwazi Ukuba idivayisi isekela iGigabit Ethernet
Awukwazi ukuthetha ngokulula ngokujonga isixhobo senyama nokuba ixhasa iGigabit Ethernet. Amadivaysi enethiwekhi anika uhlobo olufanayo lwe- RJ-45 nokuba i- Ethernet iiports ixhasa inkxaso ye-10/100 (Fast) okanye 10/100/1000 (Gigabit).
Iikhowudi zenethiwekhi zihlala zixutywe ngolwazi malunga nemigangatho abaxhasayo. Ezi zimpawu zinceda ukuqinisekisa ukuba i-cable iyakwazi ukusebenza kwi-Gigabit Ethernet ngesivinini kodwa ingabonakali ukuba umnethwekhi ulungiselelwe ukuba usebenze kuloo nqanaba.
Ukujonga ubungakanani besantya soxhumano lwe-Ethernet esebenzayo, fumana kwaye uvule izicwangciso zokuxhamla kwisixhobo somxhasi. KwiMicrosoft Windows, umzekelo, iNethiwekhi kunye noXwebhu lokwabelana> Tshintsha ifasitri yokuseta ifowuni (kufumaneka ngePlay Panel ) ikuvumela ukuba unqakraze ngokuchanekileyo ukuxhamla ukujonga isimo salo, esibandakanya isivinini.
Ukuxhuma ama-Slow Devices kwi-Gigabit Ethernet
Kwenzeka ntoni ukuba ifowuni yakho isekela kuphela, ithi, i-100 Mbps Ethernet kodwa uyifake kwi-port ye-gigabit? Ingaba ngokukhawuleza ukuphucula ifowuni ukusebenzisa i-intanethi ye-gigabit?
Akunjalo, akunjalo. Zonke iilawutsha zentsasa ebanzi zixhasa iGigabit Ethernet kunye nezinye izixhobo zonxibelelwano zekhompyutha, kodwa i-Gigabit Ethernet inikezela ngokuhambelana nokubuyela kwi-100 Mbps kunye ne-10 Mbps ezixhobo ze-Ethernet.
Ukuqhagamshela kwezi zixhobo kusebenza ngokuqhelekileyo kodwa kusebenza kwisantya esilinganisiweyo esezantsi. Ngamanye amagama, unako ukudibanisa isicatshulwa esicothayo kwinethwekhi yokukhawuleza kwaye iya kwenza kuphela ngokukhawuleza nje ngokukhawuleza okulinganisiweyo. Kuyafana ukuba udibanisa i-gigabit-ifowuni enekhono kwi-network encinci; liza kusebenza nje ngokukhawuleza njengoko inethwekhi encinci.
