Lub router yog ib qho ntawm cov khoom siv tsim los tsim kho lub khoos phis tawm thiab xyuas kom nws ua haujlwm ruaj khov. Tus router txhais cov ntaub ntawv cov khoom ntawm ntau lub network, ua raws cov cai thiab cov kev txwv ib yam.
Cov Lus Qhia
Kauj ruam 1
Txhua routers tau muab faib ua cuab yeej hardware thiab software. Hardware routers yog cov khoom siv cais tsim los muab kev sib txuas lus nruab nrab ntawm ntu ntawm lub network network. Software routers yog cov khoos phis tawj uas muaj cov software tshwj xeeb los nruab rau hauv lub network. Cov Router ua haujlwm nrog txheej txheej thib peb ntawm OSI tus qauv, thaum hloov thiab hubs ua haujlwm nrog txheej txheej thib ob.

Feem ntau, ib tus router ua haujlwm los ntawm kev txhais cov kab ke uas tau muab zais hauv pob ntawv cov ntaub ntawv los ntawm lub koos pis tawj lossis lwm yam khoom siv. Cov txheej txheem no txwv tsis pub xa "cov ntaub ntawv tsis raug" mus rau cov khoos phis tawj network, yog li txo qhov kev thauj khoom ntawm lub koos pis tawj thiab nws cov khoom.

Cov khoom siv khoos phis tawm niaj hnub tsim nrog siv cov software uas muaj tswv. Qhov no txhim kho kev ua haujlwm ntawm lub ntaus ntawv thiab tso cai rau koj kom nkag tau sai thiab hloov nws chaw. Lub rooj routing yog lub luag haujlwm rau pob ntawv xa khoom faib. Feem ntau, ob txoj kev tseem ceeb tau siv los los sau nws: zoo li qub thiab hloov kho. Thawj hom yog suav cov kev uas tsis hloov hauv lub sijhawm lossis hloov ntawm lub sijhawm tamsis no. Cov qauv no yog lub sijhawm siv heev vim hais tias lub rooj ua haujlwm zoo li qub xav tau hloov thaum lub network daim phiaj xwm pauv.

Cov lus qhia txog kev hloov pauv tau txais cov pob uas tau txais thiab xa lawv mus rau qhov chaw nyob muaj tseeb, ua raws qee txoj cai. Nws siv ua rau nws yooj yim los hloov cov kev teeb tsa ntawm lub network yam tsis tas yuav rov kho dua lub router.
Kauj ruam 5
Cov routers niaj hnub tuaj yeem muab kev sib txuas lus ntawm wired thiab wireless LAN, txuas lawv ua ke. Tib lub sijhawm, txhua lub twj siv tau nkag tau Internet kev pab siv tib tus IP address sab nraud.
