Gigabit Ethernet ceev dua Fast Ethernet. Yuav kom nkag siab yog vim li cas, cia peb delve rau hauv cov ntsiab lus technical.
Fast Ethernet, tseem hu ua 100BASE-TX, yog tus qauv Ethernet uas txhawb nqa cov ntaub ntawv hloov pauv mus txog 100 megabits ib ob (Mbps). Nws siv twisted-pair copper cabling thiab 100BASE-TX signaling scheme. Cov thev naus laus zis no tau siv dav hauv xyoo 1990s thiab muab kev txhim kho tseem ceeb ntawm tus qauv Ethernet thawj, uas ua haujlwm ntawm 10 Mbps.
Ntawm qhov tod tes, Gigabit Ethernet, tseem hu ua 1000BASE-T lossis 1 GbE, yog tus qauv Ethernet uas txhawb nqa cov ntaub ntawv hloov pauv mus txog 1000 megabits ib ob, lossis 1 gigabit ib ob (Gbps). Nws kuj tseem siv twisted-pair copper cabling tab sis siv cov phiaj xwm sib txawv hu ua 1000BASE-T.
Qhov sib txawv tseem ceeb ntawm Fast Ethernet thiab Gigabit Ethernet nyob hauv cov ntaub ntawv hloov pauv lawv txhawb nqa. Gigabit Ethernet muab cov ntaub ntawv tus nqi uas yog kaum npaug sai dua Fast Ethernet. Qhov kev nce hauv qhov nrawm no ua rau muaj kev sib kis ntau ntawm cov ntaub ntawv loj, txo cov kev sib txuas ntawm lub network, thiab txhim kho kev ua haujlwm hauv network tag nrho.
Gigabit Ethernet feem ntau yog siv nyob rau hauv niaj hnub networking ib puag ncig, tshwj xeeb tshaj yog rau cov kev siv uas yuav tsum tau high bandwidth, xws li video streaming, loj hloov ntaub ntawv, thiab cov ntaub ntawv-intensive hauj lwm. Nws tau dhau los ua tus qauv rau kev sib txuas hauv zos hauv zos (LANs) thiab feem ntau pom muaj nyob hauv tsev, chaw ua haujlwm, thiab cov chaw khaws ntaub ntawv.
Thaum qhov sib txawv ntawm qhov ceev ntawm Fast Ethernet thiab Gigabit Ethernet yog qhov tseem ceeb, nws tsim nyog sau cia tias qhov tseeb cov ntaub ntawv hloov pauv koj ua tiav yuav nyob ntawm ntau yam. Cov yam tseem ceeb no suav nrog qhov zoo ntawm cov cabling, cov khoom siv hauv lub network, kev sib txuas hauv network, thiab lub peev xwm ntawm cov cuab yeej koom nrog. Nws yog ib qho tseem ceeb los xyuas kom meej tias tag nrho cov khoom hauv lub network, suav nrog cov keyboards, routers, thiab network interface phaib, txhawb Gigabit Ethernet kom siv nws lub peev xwm.
Hauv cov ntsiab lus, Gigabit Ethernet yog qhov nrawm dua li Fast Ethernet, muab cov ntaub ntawv hloov pauv mus txog 1 Gbps piv rau 100 Mbps. Nws tau dhau los ua tus qauv rau kev sib txuas ceev ceev thiab muab kev ua tau zoo rau ntau yam kev siv.
