LAN sawv cev rau thaj chaw hauv cheeb tsam. LAN yog ib pawg ntawm cov khoos phis tawj thiab cov khoom siv uas nyob hauv ib qho chaw tshwj xeeb. Cov khoom siv txuas rau LAN nrog Ethernet cable lossis los ntawm Wi-nkaus. Koj lub tsev yuav muaj LAN. Yog tias koj lub PC, ntsiav tshuaj, ntse TV, thiab lub tshuab luam ntawv wireless txuas los ntawm koj lub Wi-Fi, cov khoom siv txuas nrog no yog ib feem ntawm koj LAN. Tsuas yog cov khoom siv uas koj tso cai nkag tau rau koj lub LAN.
Ab nyuag keeb kwm ntawm LAN
LANs tau xub siv los ntawm cov tsev kawm qib siab thiab tsev kawm qib siab hauv xyoo 1960s. Cov khoos phis tawj hauv computer no tau siv los sau cov ntawv sau hauv tsev qiv ntawv, teem caij rau cov chav kawm, sau cov qhab nia ntawm cov tub ntxhais kawm, thiab sib qhia cov khoom siv.
LANs tsis tau nrov nrog cov koom haum ua lag luam txog thaum tom qab Xerox PARC tsim Ethernet hauv xyoo 1976. Chase Manhattan Bank hauv New York yog thawj zaug kev lag luam siv cov cuab yeej tshiab no. Thaum ntxov xyoo 1980, ntau lub lag luam muaj kev sib txuas hauv internet (intranet) uas muaj ntau pua lub khoos phis tawj uas sib koom tshuab luam ntawv thiab khaws cov ntaub ntawv ntawm ib qhov chaw.
Tom qab tso tawm Ethernet, cov tuam txhab xws li Novell thiab Microsoft tau tsim cov khoom siv software los tswj cov Ethernet LAN tes hauj lwm. Nyob rau tib lub sijhawm, cov cuab yeej sib txuas lus no tau dhau los ua ib feem ntawm cov khoos phis tawj nrov ua haujlwm. Microsoft Windows 10 muaj cov cuab yeej los teeb tsa lub network hauv tsev.
yam ntxwv ntawm LAN
LANs tuaj ntau qhov ntau thiab tsawg. Ib pawg ntawm cov khoom siv txuas nrog hauv tsev sib txuas hauv internet yog LAN. Cov lag luam me muaj LANs uas txuas rau kaum lossis ib puas lub khoos phis tawj nrog cov tshuab luam ntawv thiab cov ntaub ntawv khaws cia. Qhov loj tshaj plaws LANs yog tswj los ntawm lub server uas khaws cov ntaub ntawv, sib qhia cov ntaub ntawv ntawm cov khoom siv, thiab coj cov ntaub ntawv mus rau cov tshuab luam ntawv thiab cov tshuab luam ntawv.
A LAN txawv ntawm lwm hom computer networks (xws li internet) nyob rau hauv uas cov cuab yeej txuas nrog LAN nyob hauv tib lub tsev xws li tsev, tsev kawm ntawv, lossis chaw ua haujlwm. Cov khoos phis tawj, tshuab luam ntawv, tshuab luam ntawv, thiab lwm yam khoom siv txuas nrog lub router nrog Ethernet cable lossis los ntawm wireless router thiab Wi-Fi nkag mus. Ntau lub LANs tuaj yeem txuas tau ntawm kab xov tooj lossis xov tooj cua.
Ob Hom Hauv Cheeb Tsam Networks
Muaj ob hom LANs: tus neeg siv khoom / server LANs thiab cov phooj ywg-rau-peer LANs.
Client / Server LANs muaj ntau yam khoom siv (cov neeg siv khoom) txuas nrog lub hauv paus server. Tus neeg rau zaub mov tswj xyuas cov ntaub ntawv khaws cia, nkag mus rau lub tshuab luam ntawv, thiab kev siv network. Tus neeg siv khoom tuaj yeem yog tus kheej lub computer, ntsiav tshuaj, lossis lwm yam khoom siv uas khiav cov ntawv thov. Cov neeg siv khoom txuas mus rau lub server txawm nrog cables lossis los ntawm kev sib txuas wireless.
Peer-to-Peer LANs tsis muaj lub hauv paus server thiab tsis tuaj yeem ua haujlwm hnyav xws li tus neeg siv khoom / server LAN. Ntawm cov phooj ywg-rau-peer LAN, txhua tus kheej lub khoos phis tawj thiab cov cuab yeej sib koom ua ke sib npaug hauv kev khiav lub network. Cov cuab yeej sib faib cov peev txheej thiab cov ntaub ntawv los ntawm kev sib txuas nrog lossis wireless txuas rau lub router. Feem ntau hauv tsev network yog cov phooj ywg-rau-peer.
Yuav siv LAN hauv tsev li cas
Ib lub tsev LAN yog txoj hauv kev zoo los tsim kev sib txuas ntawm txhua lub cuab yeej hauv koj lub tsev suav nrog PCs, laptops, ntsiav tshuaj, smartphones, tshuab luam ntawv, fax tshuab, thiab cov khoom siv ua si. Thaum koj cov cuab yeej txuas nrog koj lub Wi-Fi, koj tuaj yeem faib cov ntaub ntawv ntiag tug nrog cov neeg hauv tsev neeg, luam tawm wirelessly ntawm txhua lub cuab yeej, thiab nkag mus rau cov ntaub ntawv ntawm lwm cov khoom siv sib txuas.
Ib lub tsev LAN tseem tuaj yeem nthuav dav kom suav nrog kev ruaj ntseg hauv tsev, TVs ntse, kev tswj hwm ib puag ncig hauv tsev, thiab cov khoom siv hauv chav ua noj ntse. Thaum cov tshuab no tau ntxiv rau LAN, txhua qhov system tuaj yeem tswj tau los ntawm ib qho khoom siv thiab qhov chaw nyob hauv tsev.
Yog tias koj muaj Wi-Fi internet hauv koj lub tsev, koj npaj tau teeb tsa lub tsev wireless LAN.
FAQ
LAN cable yog dab tsi?
A LAN cable tseem hu ua Ethernet cable. Koj siv Ethernet cables los txuas cov khoom siv rau lub router hauv ib cheeb tsam hauv cheeb tsam network. Ethernet cables kuj muaj cov kev ncua deb uas lawv ua haujlwm tau zoo. Piv txwv li, rau CAT 6 Ethernet cables, qhov kev ncua deb yog 700 ko taw. Yog li ntawd, txhua yam khoom siv nyob deb ntawm lub router yuav tsum txuas wirelessly.
Dab tsi yog wireless LAN adapter?
Yog tias ib lub cuab yeej tsis muaj peev xwm ua tau hauv wireless, lub wireless LAN (Network) adapter ua rau nws muaj peev xwm txuas lub cuab yeej mus rau lub router.
LAN chaw nres nkoj yog dab tsi?
A LAN chaw nres nkoj yog tib yam li Ethernet chaw nres nkoj. Cov khoom siv uas tsis siv wireless yuav tsum txuas rau lub router siv Ethernet cable hauv Ethernet / LAN chaw nres nkoj.
