Obwerezabwereza: Ma Signal Regeneration Hubs mu Network Networks

Obwerezabwereza ndi maziko ofunikira mu maukonde amakono olumikizirana. Ntchito yawo yayikulu ndikuthana ndi kuwonongeka kwa ma siginecha komwe kumachitika chifukwa cha kuchepetsedwa kwa mtunda kapena kusokoneza panthawi yopatsira. Monga gawo lofunikira la gawo lakuthupi, obwereza amagwiritsa ntchito ukadaulo wowongolera ma siginecha apakompyuta kuti awonjezere maulalo olumikizirana.

Mwaukadaulo, zobwerezabwereza zimagwira ntchito-zowirikiza kawiri, kukulitsa, kuumba, ndi kuchedwetsanso nthawi ya siginecha yocheperako polandila. Pamene zizindikiro zamagetsi kapena kuwala zikuyenda mtunda wautali, matalikidwe awo amawola pang'onopang'ono ndipo mawonekedwe ake amasokonekera. Kusokoneza uku kungathe kuonjezera chiwerengero cha zolakwika pang'ono pamapeto olandira. Zobwerezabwereza zimabwezeretsa mphamvu za ma siginolo pogwiritsa ntchito{4}}zozungulira zokulira bwino kwambiri komanso zimagwiritsa ntchito umisiri wa mawonekedwe a mafunde pofuna kuthetsa phokoso, potsirizira pake kutumizanso ma siginecha okonzedwa, oyera ku sikelo yotsatira yotumizira. Mu fiber-optic communications, optoelectronic repeaters amathanso kuchita kuwala-mpaka{8}}kumagetsi-ku{10}}kusintha mawonedwe, kupititsa patsogolo mtunda wotumizira ma fiber ku ma kilomita mazana.

Obwerezabwereza ali ndi ntchito zambiri. Pamanetiweki achikhalidwe, -ma Ethernet awiriwa amagwiritsa ntchito ma hubs (makamaka obwereza) kulumikiza ma nodi angapo; mawayilesi olumikizirana opanda zingwe amadalira ma relay kuti awonjezere kufalikira; ndipo ntchito zofufuza zakuzama zakuthambo zimadalira masatilaiti angapo otumizirana mauthenga kuti apange mlatho wolumikizana pakati pa Dziko Lapansi ndi Mwezi. M'dziko lamakono la Industrial Internet of Things, kusokoneza-osabwerezabwereza kumapangitsa kuti deta ikhale yokhazikika m'malo ovuta.

Ndi kusinthika kwaukadaulo, obwereza anzeru tsopano ali ndi zida zapamwamba monga kuwongolera kupindula komanso kuzindikira zolakwika. Ngakhale kuti zipangizo zamakono-zikuchulukirachulukira mu mtundu wa OSI, zobwerezabwereza, mwa kuphweka ndi kudalilika kwake, zimakhalabe zolimba pomanga maukonde olumikizirana ofunikira, kukhala maziko apangodya popanga dziko la digito lolumikizidwa padziko lonse lapansi.
