Cov kev tshawb nrhiav Networking Ob Lub Hlis
Qhov yooj yim hom tsev network muaj ob lub tshuab hlwb hlau xwb. Koj tuaj yeem siv hom kev sib txuas lus no sib koom ua ke, luam ntawv lossis lwm yam khoom siv hluav taws xob, thiab txawm tias muaj Internet txuas. Txhawm rau xa ob lub koos pij tawj rau kev sib faib cov thiab lwm yam kev pabcuam hauv network, xav txog cov kev xaiv uas tau hais hauv qab no
Siv ob lub kauj ntseg ncaj qha nrog Cable
Txoj kev cai sib txuas lus rau ob pawg hauv computer yuav ua kom muaj kev sib txuas siab los ntawm kev ntsaws rau ib kab hauv ob lub. Muaj ntau txoj hauv kev rau kev sib txuas lus ntawm ob lub hauv computer li no:
- Ethernet crossover cable
- Null modem serial cable los yog cable peripheral
- USB- cables tshwj xeeb
1. Ethernet: Ethernet txoj kev xaiv yog tus xaiv dua li nws txhawb kev txhim khu kev ruaj ntseg, kev kub ceev nrog kev tsim nyog tsawg. Txuas ntxiv, Ethernet technology muaj kev daws teeb meem zoo tshaj plaws, tso cai rau cov tes hauj lwm uas muaj ntau tshaj ob lub khoos phis tawm los ua tau yooj yim tom qab. Yog tias ib qho ntawm koj cov computers muaj ib lub tshuab hluav taws xob Ethernet tab sis lwm tus muaj USB, ib qho Ethernet crossover cable tseem siv tau los ntawm qhov xub thawj txuas rau lub chaw txuas mus rau USB-to-Ethernet mus rau hauv lub computer USB chaw nres nkoj .
Saib kuj: Ethernet crossover cables
2. Serial thiab mus tib seem: Qhov hom cabling, hu ua Direct Cable Connection (DCC) thaum siv Microsoft Windows, muaj kev ua qis tab sis muaj cov kev ua haujlwm zoo tib yam li Ethernet cables. Koj tuaj yeem xaiv qhov kev xaiv no yog tias koj muaj cov cables nkag tau yooj yim thiab ceev ceev ntawm lub network tsis yog kev txhawj xeeb. Cov xov tooj cua thiab cov hlua sib txig sib luag yeej tsis tau siv network ntau tshaj ob lub tshuab computer.
3. USB: Cov kab mob hauv USB yuav tsum tsis txhob siv coj los txuas ob lub computer ncaj qha mus rau ib leeg. Kev sim ua kom tau hluav taws xob ua rau lub computer puas! Txawm li cas los xij, tshwj xeeb USB cables tsim rau kev sib txuas ncaj nraim uas yuav siv tau yam xyuam xim. Koj tuaj yeem xav tau qhov kev xaiv no dua lwm tus yog tias koj lub koos pis tawj tsis muaj haujlwm Ethernet network adapters.
Ua kom muaj kev sib txuas nrog Ethernet, USB, tso zis los sis cov kab khiav ua haujlwm sib luag yuav tsum:
- txhua lub computer muaj ib qho kev ua haujlwm network nrog ib lub tsho sab nrauv rau cable, thiab
- cov chaw siv network ntawm txhua lub computer yog tsim kho kom haum
Ib tug xov tooj kab lossis lub zog qaum yuav siv tsis tau ncaj qha mus txuas ob lub hauv computer mus rau lwm tus sib tham.
Siv Ob Lub Kwv Tshuab Nrog Cable Ntawm Central Infrastructure
Siv ntau tshaj ob kab txuas hauv tshuab computer, cov computers siv tau los ntawm kev sib txuas ntawm lub hauv paus ntawm qhov chaw sib txuas. Txoj kev no yuav tsum muaj ob lub vas sab hauv network , ib qho txuas rau txhua lub computer mus rau lub teeb. Muaj ntau hom teeb meem muaj nyob rau hauv tsev networking:
Kev siv txoj kev ua no feem ntau ua rau cov nqi hluav taws xob ntxiv los yuav ntau cov cables thiab network infrastructure . Txawm li cas los xij, nws yog ib qho kev tsim kho dav dav kom haum rau txhua tus neeg tsim nyog (xws li, kaum lossis ntau dua). Koj yuav xav tau qhov kev qhia no yog tias koj npaj siab nthuav koj lub network yav tom ntej.
Cov cabled feem ntau siv cov tshuab hluav taws xob Ethernet. Xwb, USB hubs yuav ua hauj lwm, thaum powerline thiab phoneline lub tsev tes hauj lwm txhua qhov muab lawv daim ntawv tshwj xeeb ntawm lub tuam tsev hauv paus loj. Cov txheej txheem Ethernet cov qauv yog feem ntau tau txais kev tso siab thiab muaj kev kawm siab.
Siv ob lub koos pij tawj Wirelessly
Nyob rau hauv xyoo tas los, cov ntsiab lus siv wireless tau nyiam ua rau muaj kev sib koom tes hauv tsev . Raws li nrog cov kev daws teeb meem, ntau yam wireless technologies muaj nyob los txhawb nqa ob lub computer network:
WI-Fi kev sib txuas yuav ncav cuag ib qho chaw nyob deb tshaj qhov wireless cov kab nyob saum toj no. Muaj ntau cov computers tshiab, tshwj xeeb tshaj yog cov phau ntawv laptops, tam sim no muaj peev xwm ua rau hauv Wi-nkaus muaj peev xwm, ua rau nws nyiam xaiv ntau zaus. WI-Fi yuav siv tau nrog lossis tsis muaj qhov sib txuas lus. Nrog ob lub koos pij tawj, WI-FI networking rho tawm (qhov tseem hu ua ad-hoc hom ) yog qhov yooj yim kom teeb tsa.
Yuav ua li cas - Teem ib Ad Hoc WiFi Network
Bluetooth technology txhawb nqa high-speed wireless txuas ntawm ob lub tshuab computer uas tsis tas siv qhov kev sib txuas lus. Bluetooth feem ntau yog siv thaum sib tham nrog lub computer nrog tus neeg siv khoom ntiag tug xws li xov tooj ntawm tes. Feem ntau cov desktop thiab cov laus dua tsis muaj peev xwm Bluetooth. Bluetooth ua haujlwm zoo tshaj yog tias ob qho khoom siv nyob rau hauv tib chav nyob ze rau ib leeg. Xav txog Bluetooth yog tias koj muaj kev txaus siab rau kev sib tham nrog cov cuab yeej thiab cov koos pis tawj tsis muaj peev xwm Wi-nkaus.
Infrared networking muaj nyob rau ntawm laptops xyoo ua ntej Wi-nkaus los yog Bluetooth yees ua nrov. Cov kev sib txuas sib txuas tsuas yog ua haujlwm ntawm ob lub koos pis tawj, tsis tas yuav tsum tau kho, thiab yoojyim sai. Ua yooj yim heev los tsim thiab siv, xav infrared yog tias koj lub computer txhawb nws thiab koj tsis muaj lub siab xav ua lag luam hauv Wi-nkaus los yog Bluetooth.
Yog tias koj pom cov lus piav qhia ntawm lwm lub tshuab siv hluav taws xob hu ua HomeRF , koj tuaj yeem siv tsis tau zoo. HomeRF tshuab ua obsolete ntau xyoo dhau los thiab tsis yog ib qho kev xaiv rau kev sib tham hauv tsev.
