Yuav ua li cas yog lub ntsiab lub qhov rooj

Yog hais tias koj thov kom qhov nruab nrab neeg siv ntawm qhov tseeb hais tias xws li ib tug network rooj vag, nyob rau hauv Feem ntau, cov lus teb yuav tsis hnov. Tej zaum qhov teeb meem no yog paradoxical: ib tug txiv neej khiav ib lub zos network ntawm ob peb computers siv keyboards (los yog hubs); muaj ib lub tsheb, uas yog entrusted nrog lub zog ntawm neeg rau zaub mov, tej zaum ib txhia qhov chaw hauv lub network siv los ntawm xov tooj cua zaus (Bluetooth los yog Wi-Fi). Lub sij hawm "neej ntawd hais rooj vag" yog sab laug yam tsis kom sai sai. Ua tsis muaj yuam kev: tam sim no xws intricate kev daws teeb meem feem ntau pom nyob rau hauv raug tsev cov neeg siv, tsis yog nyob rau hauv chaw ua hauj lwm thiab factories. Nws yuav tsum tau muab sau tseg tias, cuaj kaum, nws yog tiag tiag miv xws li ib tug network tsis muaj kev nkag siab, dab tsi yog qhov tseem ceeb lub rooj vag. Yog vim li cas rau qhov no yog yooj yim - nyob rau hauv khw muag khoom noj gateways yog tsis muag. Muaj routers, keyboards, lwm yam network khoom, rooj vag, tiam sis rau ib txhia yog vim li cas ua tsis tau.

Wb teem cov ntaub ntawv ncaj "Kuv" thiab to taub, thaum kawg, dab tsi yog meant by lub ntsiab txhais ntawm "neej ntawd hais rooj vag". Raws li ib qho piv txwv, peb siv cov teeb meem uas cov kev twb kev txuas rau lub ntiaj teb no hauv Internet network ntawm tus neeg siv lub tsev los ntawm kev siv ADSL technology tshaj uas twb muaj lawm lub xov tooj kab. Pairing lub modem mus rau lub computer, raws li nws yog tam sim no cob xub, ua los ntawm Wi-nkaus. A compound nrog tus kws kho mob lub network yog DVR li ib txwm cov officers. Nyob rau hauv lwm yam lus, cov nram qab no tswvyim: PC-modem feem siv ib tug cov ntaub ntawv kis tau tus mob raws tu qauv, e.g., 802.11g; thiab twb raws li cov Ethernet modem nrog sib txawv kiag li twg. Ntxiv mus, los ntawm lub network mob feem ntau cov khub yog txhab khoom mus rau tshwj xeeb cov khoom thiab ntxiv mus los ntawm optical kab. Obviously, nyob rau hauv tus neeg siv lub modem converts packets Wi-Fi cov ntaub ntawv nyob rau hauv lub Ethernet. Qhov no yog dab tsi ua rau lub network rooj vag. Yog li, lub rooj vag - yog ib tug network ntaus ntawv uas converts cov ntaub ntawv packets ntawm ib tug raws tu qauv rau lwm (xws li cov neeg txhais lus.): Xov tooj cua tsis - hlau, lub zos - ntiaj teb no network, lwm yam yuav tau siv cov tshuaj thaum lub hloov dua siab tshiab yog ua li cas rau hauv lub computer.

Mus saib lub xauv, koj tau mus rau lub computer khw thiab hais kom lawv muab kho vajtse router. Nyob rau tib lub sij hawm ib tug classic router muab network packets xwb nyob rau hauv ib zaug xwb raws tu qauv. Yog hais tias, txawm li cas los, yam tsawg kawg nyob rau ib theem hloov siab los ntseeg (khub), ces nws yog ib lub rooj vag. Piv txwv li, ib tug ntawm kev muab ib qho tso zis ntawm lub zos network ntawm cov computers rau lub ntiaj teb no - yog lub network rooj vag. Piv txwv li, ib tug ntawm uas muab network lub sij hawm rau nkag mus rau tag nrho cov neeg computers rau lub ntiaj teb no.

Nyob rau hauv lem, lub ntsiab rooj vag - qhov no yog qhov ntaus ntawv uas lub computer xa packets. Txij li thaum lub zos network, e.g., lub ntiaj teb no tso zis yuav ua tau ob peb cov khoom khiav dej num manually qhia uas node yog cov tub ntxhais. Peb yuav hais tias nyob rau hauv no txoj kev yog txiav txim los ntawm lub neej ntawd rooj vag. Yog hais tias nyob rau hauv ib tug tshwj xeeb txoj kev cov khoom yog tsis nyob ntawm dab tsi zoo ntawm tus IP-qhov chaw nyob xa ntawv mus rau (thiab tau txais nws), ces tus ua hauj lwm yuav tsum tau lub ntsiab rooj vag. Nws yuav tsum raug xam tias yog ib qho tseem ceeb feature: hauv qhov piv txwv saum toj no nrog tus ADSL modem PC network interface nws tus kheej tsis "saib" tus kws kho mob IP-qhov chaw nyob, thiab ua haujlwm nrog cov hauv qhov chaw nyob ntawm lub modem (yeej, tus Neeg Nruab Nrab). Yog hais tias tsim nyog, qhia kom meej rau qhov chaw nyob ntawm lub rooj vag kws kho mob yuav tsum tau hu rau tech nyiaj them yug. Feem ntau cov ntaub ntawv no yog laj mej pej xeem muaj. Thiab, ntawm chav kawm, muaj ib tug lwm txoj txoj kev txiav txim lub - koj yuav tsum mus cuag ib tug Ethernet cable ncaj qha mus rau lub computer network card tsis muaj ib tug intermediate ntaus ntawv. Yog li, nyob rau hauv lub system windose kawm lub rooj vag chaw nyob (tsis txhob xav yuam kev rau qhov chaw nyob ntawm koj router thiab ISP khoom) yuav ua tau tiav los ntawm lub tua kom ua ipconfig / tag nrho cov. Nws yog yooj yim los mus tsim ib tug .bat ntaub ntawv nrog rau cov nram qab no cov ntsiab lus:

ipconfig / tag nrho cov

mas

thiab ua nws.
