Routers yog cov khoom siv hluav taws xob me me uas koom nrog ntau lub computer network ua ke los ntawm kev sib txuas los sis cov sib txuas sib txuas.
Cov Routers Ua Haujlwm Li Cas
Hauv kev kho cov ntsiab lus, tus router yog ib txheej 3 lub qhov rooj txuas ntawm lub network , nws txhais tau tias nws txuas ob lossis ntau lub network thiab tias tus router koomtxoos ntawm pawg txheej txheem ntawm OSI qauv.
Routers muaj cov processor (CPU), ntau hom kev nco, thiab cov khoom tawm tswv yim (I / O) interfaces. Lawv ua hauj lwm raws li cov tshuab computer tshwj xeeb, ib qho tsis tas yuav tsum muaj cov keyboard lossis cov duab.
Lub router lub cim khw muag khoom muaj kev khiav haujlwm (O / S) . Muab piv rau cov khoom siv dav dav OS xws li Microsoft Windows los yog Apple Mac OS, router operating systems txwv qhov kev siv ntawm cov kev siv tau khiav ntawm lawv thiab tseem xav tau me ntsis nyiaj cia chaw. Piv txwv ntawm kev khiav router khiav lag luam muaj xws li Cisco Internetwork Operating System (IOS) thiab DD-WRT . Cov operating systems yog tsim rau hauv binary firmware duab thiab feem ntau hu ua router firmware .
Los tswj cov txheej txheem configuration hauv ib qhov chaw nco uas hu ua rooj noj mov , cov routers kuj tuaj yeem lim ob lub npav tuaj lossis tawm sab nrauv raws li cov chaw xa ntawv thiab cov neeg txais khoom.
Cov Routers rau Kev Ua Lag Luam thiab Internet
Ua ntej tsev network ua nrov, routers kuj yuav pom cov chaw lag luam thiab tsev kawm ntawv nkaus xwb.Txhob kim raug phav phav nyiaj thiab yuav tsum muaj kev kawm tshwj xeeb kom teeb thiab tswj.
Qhov loj tshaj plaws thiab muaj peev xwm tshaj tawm txoj kab nruab nrab ntawm cov xov tooj hauv Internet. Cov kev khiav haujlwm no yuav tsum tswj ntau cov ntaub ntawv ntawm cov ntaub ntawv ntws los ntawm thiab ntawm Internet Service Provider (ISP) tes hauj lwm
Tsev Broadband Routers
Routers tau los ua cov khoom siv dav dav thaum cov tsev neeg tau pib ntau lub computer thiab xav sib qhia hauv tsev internet
Cov tes hauj lwm hauv tsev siv Internet Protocol (IP) routers kom txuas tau cov computers mus rau lwm qhov thiab rau hauv Internet. Thaum cov menyuam yaus khiav ntawm cov tsev khiav haujlwm tau txais kev sib txuas lus nrog Ethernet cables thaum wireless routers txaus siab Wi-nkaus nrog Ethernet. Lub sij hawm broadband router siv rau txhua lub tsev wired los yog wireless router siv los sib koom siv Internet sib txuas.
Cov neeg khiav dej num hauv tsev feem ntau raug nqi hauv USD $ 100 los yog tsawg dua. Lawv yuav tsum ua kom tau nyiaj ntau dua cov lag luam hauv kev ua haujlwm vim lawv muaj tsawg dua nta. Txawm li cas los xij, cov neeg khiav dej num hauv tsev muaj ntau yam tseem ceeb hauv kev sib txuas lus hauv tsev:
- sib koom hauv tsev sib txuas hauv tsev rau ntau ntau yam khoom siv
- basic home network firewall thiab lwm yam kev txhawb nqa kev ruaj ntseg
- muaj peev xwm hloov router configuration nqis los ntawm qhov Web browsers

Lwm Hom Kev Routers thiab Routing Devices
Ib chav kawm ntawm cov npav portable Wi-Fi hu ua routers muaj kev lag luam rau cov tib neeg thiab cov tsev neeg uas xav siv cov hauj lwm ntawm tus kheej router ntawm lwm qhov chaw dhau lub tsev.
Routing devices hu ua mobile hotspots uas sib koom nrog cov xov tooj ntawm tes (cellular) nrog cov neeg tau txais Wi-nkaus kuj muaj. Ntau lub mobile hotspot li tsuas yog ua haujlwm nrog qee hom kev pabcuam ntawm tes.
Xaiv ib lub tshuab
Muaj ntau ntau hom routers muaj. Los ntawm tsawg tshaj plaws rau saum toj kawg nkaus, hauv qab no yog qee tus routers muaj, thiab lawv nyob tag nrho muaj nyob ntawm Amazon.com:
802.11ac Routers
Linksys EA6500 : Qhov no yog Linksys ua ntej ntse ntse WiFi router thiab muab cov neeg siv tag nrho cov kev tiv thaiv ntawm cov wireless network hauv lawv lub tsev.
Netgear AC1750 (R6300) : Kev xaiv khoom zoo rau cov tsev loj muaj ntau lub wireless.
802.11n Routers
Netgear N300 WNR2000 : Qhov no yog qhov zoo tshaj plaws router thiab lub luag haujlwm tiv thaiv lub luag haujlwm txhais tau tias yog koj khiav mus rau tej teeb meem thaum siv nws, koj tuaj yeem hu rau Netgear los pab txhim kho qhov teeb meem.
TP-LINK TL-WR841N : TP-LINK routers muaj qee yam kev nrhiav tom qab ntawm lub khw. Cov TL-WR841N nta cov khoom siv sab nrauv uas ua kom muaj kev sib txuas.
802.11g Routers
NetGear WGR614 : Tus WGR614 yog thawj tus nqi router nrog lub teeb liab dav dav (zoo tagnrho rau tsev nrog cib ntsa lossis lwm yam kev pom zoo). Thiab, muaj peb xyoo warranty.
Linksys WRT54G Wireless-G : This Linksys router tsis siv txhua lub sij hawm rau nruab thiab nws cov teeb liab muaj zog ntau txhais tau tias koj yuav tsis tau txhawj txog qeeb-loading nplooj ntawv.
