Hauv kev sib txuas lus, routers ua lub luag haujlwm tseem ceeb hauv kev tswj cov ntaub ntawv sib txawv ntawm cov khoom siv thiab internet. Nkag siab txog ntau qhov chaw nres nkoj ntawm lub router yog qhov tseem ceeb rau txhua tus uas tab tom nrhiav txhim kho lawv lub peev xwm teeb tsa lub network. Tsab ntawv xov xwm no muab cov npe dav dav ntawm cov chaw nres nkoj router, piav qhia lawv cov haujlwm thiab qhov tseem ceeb hauv kev tswj hwm network.
1. Ethernet chaw nres nkojEthernet chaw nres nkoj yog kab tias qhov yooj yim tshaj plaws pom tau yooj yim interfaces ntawm lub router. Cov chaw nres nkoj no tso cai rau kev sib txuas ntawm cov khoom siv xws li khoos phis tawj, tshuab luam ntawv, thiab keyboards. Routers feem ntau muaj ntau qhov chaw nres nkoj Ethernet, feem ntau sau npe ua LAN (Local Area Network) chaw nres nkoj. Standard Ethernet ports siv RJ-45 connectors thiab txhawb ntau yam ceev, xws li Fast Ethernet (100 Mbps), Gigabit Ethernet (1 Gbps), thiab txawm 10 Gigabit Ethernet nyob rau hauv ntau tshaj configurations.
2. WAN chaw nres nkojWide Area Network (WAN) chaw nres nkoj yog lwm qhov tseem ceeb ntawm lub router. Qhov chaw nres nkoj no txuas lub router mus rau koj lub Internet Service Provider (ISP) ntawm modem. WAN cov chaw nres nkoj feem ntau txawv ntawm LAN cov chaw nres nkoj thiab feem ntau yog sau kom meej meej. Nkag siab txog kev ua haujlwm ntawm WAN chaw nres nkoj yog qhov tseem ceeb rau kev teeb tsa koj qhov kev sib txuas hauv is taws nem thiab tswj hwm kev sib txuas sab nraud.
3. USB chaw nres nkoj
Ntau lub routers niaj hnub tuaj nruab nrog USB chaw nres nkoj, uas muaj ntau yam. Lawv tuaj yeem siv los txuas cov cuab yeej cia sab nraud, tso cai rau cov neeg siv tau yooj yim faib cov ntaub ntawv hla lub network. Tsis tas li ntawd, USB ports txhawb nqa lub tshuab luam ntawv sib koom, tso cai rau ntau yam khoom siv nkag mus rau tib lub tshuab luam ntawv. Qee lub routers txawm txhawb 4G LTE USB modems, muab kev sib txuas hauv network thaub qab thaum qhov kev sib txuas tseem ceeb hauv lub network tsis ua haujlwm.
4. Console chaw nres nkojLub console chaw nres nkoj yog ib qho tshwj xeeb interface feem ntau siv rau kev teeb tsa thiab kev tswj hwm. Cov thawj coj hauv network tuaj yeem txuas ncaj qha rau lub router siv lub console cable thiab davhlau ya nyob twg emulator los ntawm qhov chaw nres nkoj no. Los ntawm qhov chaw nres nkoj console, cov thawj coj tuaj yeem nkag mus rau lub router's command-line interface (CLI) los ua cov kev teeb tsa siab, kev daws teeb meem, thiab saib xyuas kev ua haujlwm hauv network.
5. Fais fab chaw nres nkojTxawm hais tias qhov chaw nres nkoj fais fab tsis yog cov ntaub ntawv sib txuas, nws tseem ceeb heev rau kev ua haujlwm ntawm router. Qhov chaw nres nkoj no txuas lub router mus rau lub zog hluav taws xob, kom ntseeg tau tias nws ua haujlwm tsis tu ncua. Qee lub routers kuj txhawb zog dhau Ethernet (PoE), uas tso cai rau lub zog kom tau txais los ntawm Ethernet cable, ua kom yooj yim rau kev teeb tsa thiab txo cov kab sib txuas.
6. Kav hlau txais xov chaw nres nkoj
Rau cov routers nruab nrog cov kav hlau txais xov sab nraud, cov kav hlau txais xov cov chaw nres nkoj yog qhov tseem ceeb rau kev txhim kho lub teeb liab wireless thiab kev pab them nqi. Cov chaw nres nkoj no tso cai rau cov neeg siv txuas cov kav hlau txais xov ntxiv lossis hloov cov uas twb muaj lawm, yog li txhim kho kev ua haujlwm hauv network. Kev nkag siab yuav ua li cas txhawm rau txhim kho qhov chaw kav hlau txais xov tuaj yeem cuam tshuam kev sib txuas wireless zoo hauv tsev lossis chaw ua haujlwm ib puag ncig.
7. SFP Chaw nres nkojCov qauv me me (SFP) cov chaw nres nkoj feem ntau pom muaj nyob hauv cov routers siab dua, tshwj xeeb tshaj yog nyob rau hauv kev lag luam ib puag ncig. Cov chaw nres nkoj no tso cai rau kev sib txuas ntawm fiber ntau optic cables, ua kom cov ntaub ntawv ceev ceev kis tau mus ntev. SFP cov chaw nres nkoj muaj ntau yam, txhawb ntau hom transceivers, thiab tuaj yeem hloov tau raws li qhov xav tau kom ua tau raws li cov kev xav tau hauv network.
nyob rau hauv xaus
Nkag siab txog ntau qhov chaw nres nkoj ntawm lub router yog qhov tseem ceeb rau kev teeb tsa lub network zoo thiab kev tswj hwm. Txhua qhov chaw nres nkoj muaj lub hom phiaj tshwj xeeb, xws li los ntawm kev sib txuas cov khoom siv thiab muab kev nkag mus rau hauv internet kom txhim kho kev ua haujlwm wireless. Kev paub txog cov kev sib txuas no tso cai rau koj los txhim kho kev teeb tsa network, daws teeb meem zoo dua, thiab ua kom muaj kev sib txuas zoo. Txawm hais tias koj yog ib tus neeg siv hauv tsev lossis tus thawj coj hauv lub network, kev paub txog cov chaw nres nkoj router yuav tsis muaj kev txhawj xeeb txhim kho koj lub peev xwm tswj xyuas network.
