Dab tsi yog ob txoj haujlwm ntawm cov khoom siv nruab nrab ntawm anetwork ? (Xaiv ob .) Lawv yog thawj qhov chaw thiab muab cov ntaub ntawv thiab cov kev pabcuam kom xaus cov khoom siv . Lawv khiav cov ntawv thov uas txhawb kev sib koom tes rau kev lag luam. Lawv tsim lub interface ntawm tib neeg network thiab kev sib txuas lus hauv qab network.
Ib yam li ntawd, cov haujlwm ntawm cov khoom siv nruab nrab yog dab tsi?
Cov khoom siv nruab nrab interconnect kawg cov khoom siv . Cov no cov khoom siv muab kev sib txuas thiab ua haujlwm tom qab ntawm qhov xwm txheej kom ntseeg tau tias cov ntaub ntawv ntws thoob plaws lub network. Cov khoom siv nruab nrab txuas tus tswv tsev rau lub network thiab tuaj yeem txuas ntau lub network rau ib tus neeg los tsim ib lub network.
Dab tsi yog cov cuab yeej kawg hauv network? Kev txhais ntawm: kawg ntaus ntawv . kawg ntaus ntawv . Asource los yog qhov chaw ntaus ntawv nyob rau hauv lub network system. Piv txwv li, tus neeg siv lub PC yog ib qho kawg ntaus ntawv , thiab yog li ntawd yog lub server. Network keyboards, routers thiab lwm yam khoom siv ua hauj lwm nyob rau hauv nruab nrab kom pab tau cov lus mus los ntawm ib tug kawg ntaus ntawv rau lwm tus.
Ua raws li qhov kev pom no, ob txoj hauv kev siv dab tsi los pab xaiv lub network?
(Xaiv ob .) Kev piav qhia: Cov txheej txheem rau xaiv lub network nruab nrab yog qhov kev ncua deb xaiv nruab nrab tuaj yeem ua tiav lub teeb liab, ib puag ncig hauv qe cov xaiv nruab nrab yog yuav tsum tau ntsia, tus nqi ntawm cov ntaub ntawv thiab qhov ceev ntawm cov ntaub ntawv yuav tsum tau kis, thiab tus nqi ntawm nruab nrab thiab nws installation.
Peb cov khoom siv twg yog cov khoom siv nruab nrab hauv lub network?
(Xaiv peb.)
- router.
- server.
- hloov.
- chaw ua haujlwm.
- network tshuab luam ntawv.
- wireless access point. Kev piav qhia: Cov khoom siv nruab nrab hauv anetwork muab kev sib txuas hauv network rau cov khoom siv kawg thiab xa cov ntaub ntawv xa mus rau cov neeg siv khoom thaum sib txuas lus cov ntaub ntawv.
