Gigabit Ethernet yog ib feem ntawm tsev neeg Ethernet kev sib txuas lus hauv computer thiab kev sib txuas lus. Tus txheej txheem Gigabit Ethernet txhawb zog siab tshaj plaws ntawm cov ntaub ntawv 1 gigabit thib ob (Gbps) (1000 Mbps).
Thaum xub thawj tsim, qee qhov kev xav tau nce gigabit speeds nrog Ethernet yuav tsum siv fiber ntau optic lossis lwm qhov network tshwj xeeb. Txawm li cas los xij, qhov no tsuas yog qhov tsim nyog rau kev ncua ntev.
Hnub no tus Gigabit Ethernet ua haujlwm zoo siv cov khub sib tw txuas (piv txwv, CAT5e thiab CAT6 cabling standards) zoo ib yam li 100 Mbps Fast Ethernet (uas ua haujlwm CAT5 cables ). Cov kab hom no yog ua raws li tus qauv ntawm 1000BASE-T cab txheem (tseem hu ua IEEE 802.3ab).
Gigabit Ethernet nyob hauv kev xyaum sai npaum li cas?
Vim hais tias muaj xws li network raws tu qauv nyiaj siv ua haujlwm thiab kev rov qab xa rov qab vim kev sib tsoo lossis lwm yam kev ua txhaum, cov cuab yeej tsis tuaj yeem hloov tau cov ntaub ntawv xov ntawm 1Gbps tag nrho (125 MBps).
Txawm li cas los xij, cov ntaub ntawv xa mus rau qhov cable kuj tseem ncav cuag 900 Mbps yog tias tseem yog luv luv rau cov sij hawm luv luv.
Ntawm PCs, disk drives tau zoo heev txo cov kev kawm ntawm Gigabit Ethernet kev twb kev txuas. Traditional hard drives tig ntawm cov nqi ntawm 5400 thiab 9600 revolutions ib pliag, uas tsuas yog lis cov ntaub ntawv xa mus rau ntawm 25 thiab 100 megabayt ib ob.
Thaum kawg, qee tus neeg khiav dej num nrog Gigabit Ethernet cov chaw nres nkoj yuav muaj CPUs uas tsis muaj peev xwm tswj xyuas cov khoom yuav tsum tau los txhawb kev ua lag luam lossis cov ntaub ntawv tawm ntawm cov kev sib txuas ntawm kev sib txuas. Muaj ntau tus neeg pab kiag li lawm thiab cov chaw sib koom tes sib txuas network, qhov tsawg dua rau lub tshuab khiav khiav router los pab txhawb kev them nyiaj ntau tshaj plaws ntawm kev sib txuas lus.
Tseem muaj qhov zoo tshaj ntawm bandwidth limiting qhov kev twb kev txuas txij li thaum txawm tias ib lub tsev network tseem tuaj yeem tau download speeds ntawm 1 Gbps, txawm tias ob qhov sib txuas kiag tam sim ntawd halve qhov muaj bandwidth rau ob qho tib si. Qhov no kuj muaj tseeb rau txhua yam khoom siv, xws li tsib faib cov 1 Gbps rau tsib daim (200 Mbps txhua).
Yuav Paub Li Cas Yog Ib qho Dais Pab Txhawb Gigabit Ethernet
Koj tsis tuaj yeem piav qhia tsuas yog saib ntawm lub cev ntaus ntawv seb nws puas txhawb nqa Gigabit Ethernet. Cov cuab yeej network yog muab hom RJ-45 txuas sib txuas ua ke seb lawv qhov Ethernet ports txhawb zog 10/100 (Fast) lossis 10/100/1000 (Gigabit).
Network cables feem ntau stamped nrog cov ntaub ntawv hais txog cov qauv lawv txhawb. Cov cim no pab kom paub meej tias kab ua lag luam puas muaj peev xwm khiav tau ntawm Gigabit Ethernet speeds, tiam sis tsis qhia seb lub network puas ua tau raws li qhov nqi.
Txheeb xyuas qhov ntaus nqi ntawm qhov sib txuas nrog Ethernet network, nrhiav thiab qhib cov kev sib txuas ntawm tus neeg siv khoom. Hauv Microsoft lub Xeev, piv txwv li, Network thiab Sib Tw Qhov Chaw> Hloov daim adapter nqis qhov rai (yoojyim los ntawm Kev Tswj Vaj Huam Sib Luag ) ua rau koj muaj txoj cai txuas mus saib nws txoj cai, uas muaj qhov ceev.
Txuas Kev Ceev Qis rau Gigabit Ethernet
Yuav ua li cas yog hais tias koj ntaus ntawv tsuas txhawb, hais, 100 Mbps Ethernet tab sis koj ntsaws rau hauv qhov chaw nres nkoj gigabit-muaj peev xwm tau? Puas yog nws kho tau cov cuab yeej siv los siv internet gigabit instantly?
Tsis yog, nws tsis haum. Tag nrho cov kev siv xov tooj tshiab tshaj plaws txhawb Gigabit Ethernet nrog rau lwm cov khoom siv hauv computer network, tab sis Gigabit Ethernet kuj muab rov qab sib tw kom dhau 100 Mbps thiab 10 Mbps legacy Ethernet devices.
Cov kev sib txuas rau cov khoom siv no feem ntau tab sis ua ntawm qhov ceev tsawg dua. Nyob rau hauv lwm yam lus, koj tuaj yeem txuas tus qeeb ntaus mus rau lub vas sab vas nthiv thiab nws tsuas yog ua tau raws li qeeb raws li qeeb qeeb. Ib yam yog muaj tseeb yog tias koj txuas ib lub device gigabit-muaj peev rau lub network qeeb; nws yuav tsuas khiav lag luam sai dua li qeeb qeeb network.
