I-Gigabit Ethernet iyingxenye yomndeni we- Ethernet wamanethiwekhi okuxhumana namakhompyutha nokuxhumana. I-Standard Gigabit Ethernet isekela isilinganiso sezinga eliphezulu sedatha ye-1 gigabit ngomzuzwana (Gbps) (1000 Mbps).
Uma kuqala, abanye bacabanga ukuthi ukuphumelela kwegigabit nge-Ethernet kungadinga ukusebenzisa i- fiber optic noma enye ubuchwepheshe bekhebula lobuchwepheshe bekhebula . Noma kunjalo, lokho kudingekile kuphela emabangeni amade.
I-Gigabit Ethernet yanamuhla isebenza kahle isebenzisa ikhebula lesibhaxa lesibhaxu eliphambene (ikakhulukazi, amazinga wekhamera e-CAT5e ne- CAT6 ) afana ne-100 Epspret Fast Ethernet (esebenza ngaphezulu kwezingcingo ze-CAT5 ). Lezi zinhlobo zekhebula zilandela izinga elingu-1000BASE-T (elibizwa nangokuthi i-IEEE 802.3ab).
Kanjani Ukushesha Kuyi-Gigabit Ethernet ku-Practice?
Ngenxa yezici ezinjenge- protocol yenethiwekhi ngaphezulu nokudluliselwa kabusha ngenxa yokushayisana noma ezinye ukwehluleka okwesikhashana, amadivayisi awakwazi ukudlulisela idatha yomlayezo ewusizo ngokugcwele isilinganiso esingu-1 Gbps (125 MBps).
Ngaphansi kwemibandela evamile, noma kunjalo, ukudluliswa kwedatha okuphumelelayo phezu kwekhebula kungase kufinyelele ku-900 Mbps uma kwenzeka ngisho nesikhathi esifushane.
Ku-PC, ukushayela i-disk kunganciphisa kakhulu ukusebenza koxhumano lwe-Gigabit Ethernet. Izinkomba zendabuko ezinzima zithatha amazinga phakathi kwama-5400 no-9600 ukuvuselelwa ngomzuzwana, ongakwazi ukusingatha izinga lokudluliswa kwedatha phakathi kwama-25 no-100 ama-megabytes ngomzuzwana.
Okokugcina, amanye ama-routers asekhaya ngamapayipi we-Gigabit Ethernet angase abe nama-CPU angakwazi ukuphatha umthwalo adingekayo ukusekela ukufakwa kwedatha okungenayo noma okuphumayo kumazinga aphelele wenethiwekhi. Amadivayisi amaningi amaklayenti kanye nemithombo efanayo yethrafikhi yenethiwekhi, cishe inqubo ye-router yokusekela ukukwazi ukusekela ukudluliselwa kwejubane okungaphezu kwesinye isixhumanisi esithile.
Kukhona futhi isici sokuhamba komkhawulokudonsa ukuvimbela uxhumano kusukela ngisho noma inethiwekhi yonke ekhaya ingathola isivinini sokulanda se-1 Gbps, ngisho nokuxhumana okubili ngesikhathi esisodwa ngokushesha kwehlisa umkhawulokudonsa okhona kuwo wonke amadivayisi. Kuyafana nanoma yiliphi inani lamadivayisi ahambisanayo, afana nokuhlukanisa ama-Gbps angu-1 zibe yizicucu ezinhlanu (200 Mbps ngayinye).
Indlela Yokukwazi Uma Idivayisi isekela i-Gigabit Ethernet
Awukwazi ukutshela ngokumane ngokubuka idivaysi yomzimba ukuthi isekela i-Gigabit Ethernet. Amasevisi enethiwekhi anikezela uhlobo olufanayo lwe- RJ-45 ukuthi ngabe amathrekhi awo e- Ethernet asekela 10/100 (Fast) noma 10/100/1000 (Gigabit).
Izintambo zenethiwekhi zivame ukugxilwa ngolwazi mayelana namazinga asekelayo. Lezi zimpawu zisiza ukuqinisekisa ukuthi ikhebula likwazi ukusebenza ku-Gigabit Ethernet ngesivinini kodwa angabonisi ukuthi inethiwekhi ihlelwe yini ukuba isebenze ngaleso sikhathi.
Ukuze uhlole isilinganiselo sejubane loxhumano lwenethiwekhi ye-Ethernet esebenzayo, thola futhi uvule izilungiselelo zokuxhuma kudivayisi yeklayenti. Ku-Microsoft Windows, isibonelo, i- Network and Sharing Center> Ukushintsha iwindi lamasethingi e-adapter (kufinyeleleke ngePlay Panel ) ikuvumela ngokuchofoza ngakwesokudla uxhumano ukuze ubuke isimo sawo, esihlanganisa ijubane.
Ukuxhuma amadivayisi amancane ku-Gigabit Ethernet
Kwenzekani uma idivaysi yakho isekela kuphela, ithi, 100 Mbps Ethernet kodwa uyixhuma kwichweba elikwazi ukubhekana ne-gigabit? Ingabe ivuselela ngokushesha idivayisi ukusebenzisa i-intanethi ye-gigabit?
Cha, akunjalo. Wonke ama-router omusha we- broadband asekela i-Gigabit Ethernet kanye neminye imishini yenethiwekhi ye-computer, kepha i-Gigabit Ethernet inikeza ukuhambisana okubuyiselwe kuma-100 Mbps asekudala kanye namadivayisi we-Ethernet angu-10 Mbps.
Ukuxhuma kula madivaysi kusebenza ngokujwayelekile kepha kwenziwa ngesivinini esilinganisiwe. Ngamanye amazwi, ungakwazi ukuxhuma idivayisi esheshayo kwinethiwekhi esheshayo futhi izokwenza kuphela ngokusheshisa njengejubane elilinganiselwe kakhulu. Kuyafana okufanayo uma uxhuma idivayisi ye-gigabit enamandla kwinethiwekhi encane; izosebenza nje ngokusheshisa njengenethiwekhi encane.
