Xadhkaha u gudbiya tamarta korantada ee ka imanaya xarumaha korantada ee xarumaha korantada iyo xadhkaha isku xidha nidaamyada korontada ayaa guud ahaan ah

loo yaqaan xadhkaha gudbinta.Tignoolajiyada cusub ee khadka isgaadhsiinta ee aynu maanta ka hadlaynaa maaha kuwo cusub, waxaana la is barbar dhigi karaa oo kaliya

Codsaday in ka dambeeya khadadkayada caadiga ah.Inta badan tignoolajiyadan "cusub" waa qaangaar oo in badan ayaa lagu dabaqay xadhkaha korantada.Maanta, kuwa caadiga ah

qaababka khadka gudbinta ee waxa loogu yeero "cusub" technology waxaa lagu soo koobay sida soo socota:

Tiknoolajiyada koronto ee weyn

"Shabakad koronto oo weyn" waxaa loola jeedaa nidaamka korantada ee isku xiran, nidaamka korontada wadajirka ah ama nidaam awood mideysan oo uu sameeyay isku xirnaanta

Xariiro koronto oo badan oo deegaanka ah ama koronto-goboleedka.Nidaamka korantada ee isku xiran waa isku xirnaanta isku xiran ee tiro yar

isku xirka shabakadaha korantada ee gobolka iyo shabakadaha korantada qaranka;Nidaamka awoodda isku-darka ah wuxuu leeyahay sifooyin isku-dubbarid

qorshaynta iyo dirida si waafaqsan heshiisyada ama heshiisyada.Laba ama in ka badan oo habab koronto oo yaryar ah ayaa ku xidhan shabkada korantada si ay isbarbar dhigaan

hawlgalka, kaas oo samayn kara nidaamka awood gobolka.Tiro ka mid ah nidaamyada korantada ee gobolka ayaa ku xiran koronto si ay u sameeyaan koronto wadajir ah

nidaamka.Nidaamka awoodeed ee midaysan waa nidaam awood leh oo leh qorshe midaysan, dhismo midaysan, dirid midaysan iyo hawlgelin.

impedance, fogaanta gudbinta iyo baaxadda caymisku waa weyn yahay.Isku xirka korontadu wuu sii xoogaysanayaa

ama shabakadaha korontada gobolka waa.Xasiloonida dhammaan shabaqyada korantada ka dib isku-xirnaanta waxay la xiriirtaa awoodda korantada kasta si ay u taageerto mid kasta

mid kale haddii ay dhacdo guuldarro, Taasi waa, inta badan awoodda is-dhaafsiga ee xadhkaha korantada ee u dhexeeya xadhkaha korantada ama shabakadaha korontada ee gobolka, isku xirka dhow

iyo sida uu u xasilan yahay hawlgalka shabaqlaha.

Shabakadda korontadu waa shabakad gudbineed oo ka kooban saldhigyo, saldhigyada qaybinta, xadhkaha korontada iyo tas-hiilaadka kale ee korontada.Iyaga ka mid ah,

tiro badan oo xadhkaha gudbinta ah oo leh heerka ugu sarreeya ee danab iyo saldhigyo u dhigma ayaa ka kooban xadhkaha gudbinta laf dhabarta ee

shabakad.Shabakadda korantada ee gobolka waxa loola jeedaa xadhkaha korantada ee warshado koronto oo waaweyn oo leh awood sharciyeed oo xoogan, sida Shiinaha lix gobol oo trans ah.

Korontada gobolka, halkaas oo koronto gobol kasta uu leeyahay warshado koronto kuleyl ah oo waaweyn iyo warshad koronto oo ay si toos ah u soo dirto xafiiska koronto.
