Kodi ubwino wa waya wamba wokhala ndi nsalu yotchinga moto ndi chiyani?

Kunena zongoyerekeza, kutchingira kwa ma network otchingira ma network kuli ndi zitsulo zotchingira zotchinga, kuthekera kwake kotsutsana ndi kusokoneza kuyenera kukhala kolimba. Komabe, kutetezedwa kwa zingwe zapaintaneti kumafuna kuti pulogalamu yonse yamapulogalamu iyenera kusankha zida zotetezedwa, ndipo nsalu yotchinga moto imanenanso kuti nyumbayo ili ndi chitetezo chabwino kwambiri chapansi, apo ayi ndizotheka kupanga chingwe chotchinjiriza cha zingwe zama network kukhala zizindikiro zosokoneza. Choncho, ngati sanali wapadera ayenera ndi muyezo ali, Internet mawaya kusankha sanali shielded maukonde chingwe.Nsalu yoletsa moto

Moto nsalu si zimene timanena nthawi zambiri sangakhoze moto nsalu, ali ndi yankho lapadera, akhoza kuletsa kufalikira kwa moto, mu nthawi inayake kuti mokwanira basi kuzimitsa. Chifukwa chake, kuchuluka kwa nsalu zotchingira moto nthawi zambiri kumatsimikiziridwa ndi liwiro la kuyatsa kwa nsalu. M'mawu ena, lawi-retardant carded nsalu kukhudza lawi kwa nthawi inayake m'njira yofunikira, ndiyeno lawi amachotsedwa kudziwa kachiwiri lawi ndi lawi poyatsira nthawi ya nsalu, komanso mlingo wa. kuwonongeka kwa nsalu. Kuchepa kwa nthawi yoyaka moto, kumachepetsa nthawi yoyatsira moto,Nsalu yoletsa motokutsika kwa chiwonongekocho, m'pamenenso nsalu zotchingira moto zimakwera; Izi, nazonso, zikuwonetsa kuti nsaluyo ili ndi chiwopsezo chochepa chamoto.

Pakadali pano, zingwe ziwiri zopotoka zitha kugawidwa kukhala zopotoka zosatetezedwa (UTP=UNSHILDEDTWISTEDPAIR) ndi nsalu zotchinga moto zotchingidwa zopotoka (STP=SHIELDEDTWISTEDPAIR). Mukutanthauza chiyani, tsegulani? Kumvetsetsa kosavuta ndikukulunga aluminiyumu kunja kwa ma 4 awiriawiri a zingwe zapaintaneti, zofanana ndi wosanjikiza wa aluminiyamu ndi platinamu kunja kwa mzere wa chizindikiro cha satellite. Cholinga cha chitetezo: kuteteza pulogalamu ya pulogalamu ndikuwonetsetsa bwino mawonekedwe amtundu wa pulogalamu yamapulogalamu mu chilengedwe ndi zizindikiro zosokoneza. Kuthekera kotsutsana ndi kusokoneza pano kuyenera kukhala ndi milingo ya 2, ndiko kuti, kutha kukana zosokoneza zakunja komanso kuthekera kwa pulogalamu yamapulogalamu kuti igwire ntchito zosokoneza magwero akunja.Nsalu yoletsa moto

Chingwe chachitetezo chachitetezo chamoto: nthawi zambiri moto woyaka moto / woyaka moto wabuluu ndi wofiyira wopindika-wofewa (wofiira wabwino ndi wopanda buluu), chowunikira utsi, chojambulira kutentha pamanja batani loyang'anira data ndi zina zolumikizidwa ndi chingwe cholumikizira deta. Mwachitsanzo, chizindikiro cha madzi, valavu yonyowa, valavu yotulutsa utsi, valavu yowonongeka mofulumira ndi ma modules ena olamulira amagwirizanitsidwa ndi mzere wa chizindikiro cha deta ndi zida za alamu malinga ndi chizindikiro cha deta. Chingwe chamagetsi chosinthira: Nthawi zambiri waya wofiyira wakuda kapena wofiyira wokhotakhota wakuda kapena wosayaka moto kapena waya wolimba wa BV wotchinga moto (wofiira wowoneka bwino ndi wopanda pake wakuda). Module iyenera kulumikizidwa ndi chingwe cha siginecha ya data ndi chingwe chamagetsi chosinthira.
