Njani na ukudluliselwa kolwazi

Ukutshintshelwa lolwazi ngomnye wemiba ephambili ubukho balo naluphi na uhlobo eziphilayo emhlabeni. Nkqu eziphilayo elula ekuzalweni kufuneka nethuku ezisisiseko kubanceda basinde. Le transfer ulwazi ukusuka kumthombo ukuya ngumamkeli udlula ngeendlela ezahlukahlukeneyo. Ezi ziquka indlela izivamvo, ezifana ukuva, ukubona, ngaphandle kwebala, kunye nezixhobo zobugcisa ezahlukeneyo ezinxulumene ngeengcingo.

Ukudluliselwa kolwazi kwenzeka ngohlobo umyalezo ngokusebenzisa ijelo lonxibelelwano. ulwazi olusisiseko ufakwe ube uphawu oluthi idluliselwe uthunyelwe ezi. Ifunyenwe zilungiswa yi kwisamkeli iguqulwe ibe ulwazi. Umzekelo, umyalezo imozulu luyasuka kuye kumamkeli (umboniseli) of iziko zemozulu nge ijelo lonxibelelwano (TV).

Umgangatho data ixhomekeke kwindlela ngayo ukudlulisa. Umzekelo, umfanekiso embi kwikhusi uyakwazi ukulahlekisa ngokupheleleyo kumamkeli. Ukusebenza kwe ijelo lonxibelelwano kwakhona kuchaphazela isantya kunye nenani izinto ababandakanyekayo kulo. Owona mzekelo iphawulekayo oku kuthathelwa ingqalelo i "ilizwi emlonyeni", ixesha elide ulwazi lufika kumamkeli, kokukhona amathuba okufumana ulwazi olungachanekanga.

Kweli hlabathi lanamhlanje ngakumbi zithandwa ngakumbi njengomthombo inkcazelo ukuqokelela intanethi. Omnye wemiba ephambili yophuhliso lwayo olukhawulezileyo njengoko amathuba ukufumana naluphi na ulwazi phantse naphi na emhlabeni. Kodwa ukudluliselwa kolwazi imigama emide ngokufuthi abaphumelela ilahleko okanye ukungathembeki ethile. Ngoko ke, unxibelelwano channel - into ephambili echaphazela umgangatho idatha eyafunyanwa.

Ukudluliselwa kolwazi malunga networks khompyutha okokuqala kuthwalelwa phandle usebenzisa i ifoni. Loo ndlela lineqela nezingalunganga. Nokudlulisela ulwazi olugcinwe yi-channel kakubi akhuselwe, kwaye isantya kwaye nokuthembeka uxhulumaniso ulihlwempu. Le signal ngokuphindaphindiweyo phantsi ukusebenza, ngamanye amazwi, phezu mnxeba ukusuka kumthombo awazenzayo neziko elikhulu, emva kwakhona ezinebhakhowudi sele kuchaziwe kwi kwisixhobo okhethekileyo - i modem, apho recoded ngokutsha kwaye ngoko kuphela livela kwi esweni screen.

Ifayibha inkqubo optic ukudluliselwa data iye yenguqu ukuya kwinqanaba eyahlukileyo ngokupheleleyo. Ukuza kuthi ga ngoku, amakhonkco fibre optic zinika isantya ephezulu nomgangatho wonxibelelwano. Uphawu sisasazwa photon, musa ayikhuphi i-magnetic field, yaye ngenxa yoko kwijelo onjalo alidityaniswanga evela ngaphandle, eqinisekisa iqondo eliphezulu lokhuseleko. Izinga kunye transmission umgangatho ayichaphazeleki icandelo emnqamlezweni kunye uxhathiso umqhubi, khona ufumana ulwazi ngendlela apho kuyo wathunyelwa, kwanaleyo data lwenzeka phantse washona.

Uphuhliso ngokukhawuleza CPC efunekayo ukunyusa isantya kunye Intanethi. By kade yaye zibiza WAP-uqhagamshelo kwi-high speed 4G. Inkqubela akemi ngxi, yaye ayikho kude imini xa Internet Esetyenzisiweyo ugula ngengqondo ngeselula. Isizukulwana esilandelayo iya axakwe jonga kwi Umfaki, kanye njengokuba ngoku ujonge fixed, nto leyo ngokuthe ngcembe indawo engenazingcingo.
