Yeka ukuthi ulwazi ludluliselwa kanjani

Ukudluliswa kolwazi kungenye yezici eziyinhloko zokuba khona kwanoma yiluphi uhlobo lokuphila eMhlabeni. Ngisho nezilwane ezilula kakhulu, uma zizalwa, zinezinto eziyisisekelo ezisiza ukuba zisinde. Ukudluliselwa kolwazi kusuka kumthombo kuya kumamukeli kwenzeka ngezindlela ezehlukene. Zingathathwa njengezimo zengqondo, njengokuzwa, ukubona, ukuthinta, kanye namadivayisi ahlukahlukene ezobuchwepheshe ahlobene nokuxhumana.

Ukudluliselwa kolwazi kwenzeka ngesimo somyalezo usebenzisa isiteshi sokuxhumana. Idatha yomthombo ifakwe ikhodi ibe isignali eshunyayelwa endaweni. Ama-receivals aqhutshwa yi-receiver futhi aguqulwa ngolwazi. Isibonelo, umbiko wezulu usakazwa kumamukeli (umbukeli) kusuka esikhungweni semeteorological usebenzisa isiteshi sokuxhumana (i-TV).

Ikhwalithi yedatha etholakala ngokuqondile ixhomeke kwimodi yokudlulisa. Isibonelo, isithombe esibi esibukweni sikwazi ukudukisa ngokuphelele umamukeli. Ukusebenza komzila wokuxhumana nakho kuthinteka ngejubane nenani lezici ezihilelekile kulo. Isibonelo esibaluleke kunazo zonke salokhu "izwi lomlomo": uma ulwazi lufinyelela isikhathi eside kumamukeli, lukhulu amathuba okuthola ulwazi lwamanga.

Ezweni lanamuhla, i-Inthanethi ithola ukuthandwa njengomthombo wolwazi. Esinye sezici eziyinhloko zokuthuthukiswa kwayo okusheshayo kungenzeka ukuthola ulwazi nganoma yikuphi emhlabeni. Kodwa ukudluliswa kolwazi emadolobheni amade kuvame ukulahlekelwa noma ukuphazamiseka. Ngakho-ke, isiteshi sokuxhumana yisici esiyinhloko esithonya ikhwalithi yedatha etholakele.

Ukudluliswa kolwazi kumanethiwekhi ekhompiyutha ekuqaleni kwenziwa ngokusebenzisa ifoni ehlala phansi . Le ndlela inamaphutha amaningi. Ukudluliswa kolwazi kudlule ngesiteshi esingavikelekile, futhi isivinini nokuthembeka kokuxhumeka kushicilelwe kakhulu. Isibonakaliso sasiqhutshwa izikhathi eziningana, isb. Emgqeni wefoni kusuka emthonjeni, waya esikhungweni esiyinhloko, wabe esekhokhwa kabusha futhi esethunyelwe kudivayisi ekhethekile - i-modem, lapho ehlelwa kabusha futhi kuphela evele esikrinini somqapha.

Izinhlelo zokudlulisa ulwazi lwe-Fiber-optic ziye zaba ushintsho ezingeni elihluke ngokuphelele. Kuze kube manje, ama-FOCL ahlinzeka ngejubane eliphakeme kakhulu kanye nekhwalithi yokuxhumana. Isignali idluliselwa ngamaphotons angenayo insimu ye - electromagnetic, okusho ukuthi akunakwenzeka ukuxhuma esiteshini esinjalo ngaphandle, okuqinisekisa izinga eliphezulu lokuphepha. Ijubane kanye nekhwalithi yokudluliselwa ayithinteki esigabeni esiphambene nokumelana komqhubi, lowo othola indawo uthola ulwazi ngokuqondile ngendlela asithunyelwe ngayo, futhi ukushintshaniswa kwedatha kwenzeka ngokushesha.

Ukuthuthukiswa okusheshayo kwe-CCP kudinga ukukhuphuka kwi-intanethi kanye ne-intanethi yeselula. Kusuka ku-WAP-uxhumano olusheshayo olubizayo kuya ku-4G esheshayo. Intuthuko ayimi, futhi akude kakhulu ngalolo suku lapho i-intanethi enezintambo izobanjwa yi-mobile. Isizukulwane esilandelayo sizobukeka sixakekile emgqeni we-fiber-optic, njengoba nje manje sibheka ucingo olungahleliwe lwe-telephony, oluthathwa kancane kancane yi-wireless.
