Niaj hnub no, Internet tau nkag mus rau ntau txhiab tsev neeg, thiab Internet tau dhau los ua ib qho tseem ceeb hauv peb lub neej. Feem ntau, cov khoom siv hauv tsev feem ntau yog: optical modems, routers, keyboards, wifi, tab sis ntau tus neeg siv tsis tuaj yeem paub qhov txawv lawv yooj yim. Thaum koj ntsib lub network tsis ua haujlwm thiab hu rau kev pab, nws feem ntau siv sijhawm ntev los daws qhov teeb meem vim tias koj tsis tuaj yeem paub qhov txawv ntawm cov khoom siv.

Cia kuv qhia cov ntsiab lus thiab kev ua haujlwm ntawm ntau lub network xws li optical modems, routers, keyboards, thiab wifi kom ntxaws hauv qab no.

1. Optical modem: Optical modem, tseem hu ua ib qho chaw nres nkoj optical transceiver, yog ib hom khoom siv kho qhov muag fiber ntau kis tau tus mob.
Cov xwm txheej ntawm daim ntawv thov yog: tus neeg siv-Ethernet optical modem-optical cable-E1 optical modem-2M cable-central office SDH optical transceiver A-central office SDH optical transceiver B-PDH optical transceiver-E1 rau Ethernet raws tu qauv hloov dua siab tshiab-neeg siv khoom (Ethernet hloov lossis computer thiab lwm yam).
Nco tseg: Kom paub txog kev sib txuas lus kho qhov muag, kho qhov muag hloov kho thiab demodulation yuav tsum tau ua, yog li kho qhov muag modem yog qhov tseem ceeb ntawm kev sib txuas lus fiber ntau.

2. Hloov: Lub hom phiaj tseem ceeb yog nkag mus rau Is Taws Nem los ntawm lub network cable, uas muaj kev ua haujlwm ntawm kev nthuav dav lub network chaw nres nkoj. Txawm li cas los xij, txhua tus neeg hu xov tooj hauv Internet sib cais, thiab txhua tus siv lawv tus kheej broadband. Txhua tus tsis muaj kev cuam tshuam hauv Internet, txawm tias lwm tus neeg rub tawm, nws kuj tseem yuav cuam tshuam rau lawv tus kheej hauv Internet. Tsis muaj kev cuam tshuam, thiab txhua lub khoos phis tawj siv tib lub hloov pauv nyob hauv tib lub LAN. Cov keyboards kev lag luam thiab kev lag luam PoE keyboards peb tsim tau poob rau hauv pawg no.

3. Router: Zoo li qhov hloov pauv, nws tuaj yeem nthuav dav lub network chaw nres nkoj thiab muaj lub luag haujlwm hu ua virtual. Cov khoos phis tawj txuas nrog Is Taws Nem los ntawm tib lub router sib koom tib tus account broadband, thiab txhua tus neeg siv Internet cuam tshuam rau ib leeg. Piv txwv li, yog tias lub khoos phis tawj rub tawm, lwm lub khoos phis tawj ntawm tib lub router yuav pom tseeb tias Internet ceev nrawm heev. Cov khoos phis tawj ntawm tib lub router kuj tseem nyob hauv ib cheeb tsam network. Peb cov kev lag luam 4G routers kuj muaj nyob rau hauv qeb no, thiab routers kuj tau muab faib ua ntau pawg los ntawm qib.

4. WiFi: yog ib lub tshuab uas tso cai rau cov khoom siv hluav taws xob txuas mus rau lub wireless hauv cheeb tsam network (WLAN), feem ntau yog siv 2.4G UHF lossis 5G SHF ISM xov tooj cua zaus bands. Txuas mus rau lub wireless LAN feem ntau yog tiv thaiv tus password; tab sis nws tseem tuaj yeem qhib tau, uas tso cai rau txhua lub cuab yeej nyob hauv thaj tsam ntawm WLAN txuas. Wi-Fi yog ib hom ntawm wireless network kev sib txuas lus thev naus laus zis, tuav los ntawm Wi-Fi Alliance, nrog rau lub hom phiaj ntawm kev txhim kho kev sib cuam tshuam ntawm cov khoom siv wireless network raws li IEEE 802.11 tus qauv.

Ntxiv: Qee tus neeg hais tias lub router tuaj yeem siv los ua qhov hloov pauv. Cov txheej txheem yog raws li nram no: Tsis txhob ntsaws lub network cable los ntawm optical modem rau hauv WAN chaw nres nkoj, tab sis ntsaws rau hauv ib qho chaw nres nkoj LAN. Lwm yam tseem tsis hloov. Lub sijhawm no, lub router paub txog kev ua haujlwm ntawm kev hloov pauv.
