Ethernet yog cov thev naus laus zis uas feem ntau siv hauv cov xov tooj hauv zos hauv cheeb tsam (LANs). LAN yog lub network ntawm cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob uas npog thaj tsam me xws li chav tsev, chaw ua haujlwm, lossis tsev. Nws sib txawv nrog thaj chaw dav dav (WAN), uas nthuav dav thaj chaw loj.
Ethernet yog lub network raws tu qauv uas tswj xyuas cov ntaub ntawv xa mus li cas hauv LAN thiab raug xa mus rau IEEE 802.3 raws tu qauv. Cov txheej txheem tau hloov zuj zus thiab txhim kho lub sijhawm hloov cov ntaub ntawv ntawm qhov ceev ntawm ntau tshaj li ib gigabit ib ob.
Ntau tus neeg tau siv Ethernet thev naus laus zis tag nrho lawv lub neej yam tsis paub txog. Nws zoo li tias ib qho kev sib txuas hauv koj lub chaw ua haujlwm, ntawm lub txhab nyiaj, thiab hauv tsev yog Ethernet LAN. Feem ntau cov khoos phis tawj thiab khoos phis tawj tuaj nrog daim npav Ethernet sib xyaw thiab npaj tau txuas mus rau Ethernet LAN.
Yam Koj Xav Tau hauv Ethernet LAN
Txhawm rau teeb tsa lub xaim Ethernet LAN, koj xav tau cov hauv qab no:
- Computers thiab khoom siv txuas: Ethernet txuas ib lub khoos phis tawj lossis lwm yam khoom siv hluav taws xob rau nws lub network tsuav yog lub cuab yeej muaj Ethernet adapter lossis network card.
- Network interface phaib hauv cov khoom siv: Daim npav network interface yog muab tso rau hauv lub motherboard ntawm lub khoos phis tawj lossis nruab sib cais hauv lub cuab yeej. Tseem muaj USB versions ntawm Ethernet phaib, xws li lwm dongles. Ib daim npav Ethernet hu ua daim npav network. Nws muaj cov chaw nres nkoj uas koj txuas cables. Tej zaum yuav muaj ob qhov chaw nres nkoj, ib qho rau RJ-45 jack uas txuas cov hlua khi tsis muaj kev sib tw (UTP) thiab ib qho rau lub coaxial jack ntawm daim npav network.(Txawm li cas los xij, kev sib txuas coaxial yog qhov tsawg kawg nkaus.)
- A router, hub, hloov, lossis rooj vag los txuas cov khoom siv: Lub hub yog ib qho khoom siv uas ua raws li qhov sib txuas ntawm cov khoom siv hauv lub network. Nws muaj ob peb qhov chaw nres nkoj RJ-45 uas koj ntsaws cov cables.
- Cables: UTP (Unshielded Twisted Pair) cables feem ntau siv hauv Ethernet LANs. Cov kab no zoo ib yam li hom siv rau hauv xov tooj hauv xov tooj tab sis fatter, nrog yim twisted khub ntawm cov xov hlau ntawm cov xim sib txawv hauv. Qhov kawg yog crimped nrog RJ-45 connector, uas yog ib tug loj version ntawm lub RJ-11 jacks plugs rau hauv lub xov tooj landline.
- Software los tswj lub network: Cov kev ua haujlwm niaj hnub zoo li tsis ntev los no ntawm Windows, Linux, thiab macOS muaj ntau tshaj li txaus los tswj Ethernet LANs. Thib peb software uas muab ntau yam nta thiab tswj tau zoo dua muaj.
Yuav ua li cas Ethernet ua haujlwm
Ethernet raws tu qauv xav tau kev paub hauv computer science kom nkag siab nws ua haujlwm li cas. Nov yog ib qho yooj yim piav qhia:
Thaum lub tshuab ntawm lub network xav xa cov ntaub ntawv mus rau lwm tus, nws nkag siab tus neeg nqa khoom, uas yog cov xaim tseem ceeb txuas cov khoom siv. Yog tias nws yog dawb, txhais tau tias tsis muaj leej twg xa dab tsi, nws xa cov ntaub ntawv pob ntawv ntawm lub network, thiab lwm yam khoom siv xyuas lub pob ntawv kom pom seb lawv puas yog tus txais. Tus neeg txais khoom siv lub pob ntawv. Yog tias muaj pob khoom ntawm txoj kev loj, lub cuab yeej uas xav xa rov qab rau qee txhiab tus thib ob sim dua kom txog thaum xa tuaj.
FAQ
Ethernet cable yog dab tsi?
Ethernet cables yog thawj cov khoom txuas siv hauv Ethernet network. Hauv Ethernet LAN, Ethernet cables yuav txuas ncaj qha los ntawm cov khoos phis tawj mus rau lub router / modem kom cov khoos phis tawj sib tham nrog ib leeg yam tsis tas siv internet dav dua.
Yuav ua li cas koj khiav Ethernet cables los ntawm phab ntsa?
Ua qhov qhib rau hauv koj phab ntsa thiab xov lub cable los ntawm. Rub nws tawm los ntawm lwm qhov chaw tsim uas koj xav kom lub cable mus. Ethernet cables yog tsim los rau ntau hom kev siv thiab feem ntau tsis muaj kev ceev faj tshwj xeeb.
Koj tuaj yeem yuav Ethernet cables nyob qhov twg?
Ethernet cables raug muag offline thiab online, los ntawm Amazon mus rau Qhov Zoo Tshaj Plaws thiab txhua qhov chaw hauv nruab nrab. Yog tias tus neeg muag khoom muag khoom siv hluav taws xob, muaj feem ntau lawv yuav muaj Ethernet cables, ib yam nkaus.
