Ikhompyutha Global inethiwekhi - yinto exchange enokuthenjwa yolwazi yonke imihla

Kwihlabathi abantu billion usebenzise iinkonzo kunye nezixhobo ulwazi, abonelela uthungelwano inkcazelo yekhompyutha lwehlabathi. Ngaphezulu kwe-150 iikhompyutha enxulumene-Internet ukugcina isixa esikhulu solwazi. Ukudala kwi Internet kwadala imfuneko ukwenza esinye isithuba ulwazi, ngaphandle apho ngoku akakwazi ukwenza intlangano na abasebenzi omnye '.

Ubume network computer global

Internet idibanisa abasebenzisi:

• zendawo;
• lwengingqi;
• corporate.

Inqanaba lokuqala isakhiwo ehlabathini umchiza - yendawo, ezo uthungelwano izakhiwo, ii-ofisi, apho inqwaba eziliqela computers ziyadibana ukunika ukufikelela kulwazi. networks ayide ikwazi ukubonelela ukufikelela data yomsebenzisi kwiindawo ezahlukeneyo kulo mzi. uthungelwano zommandla - ngumphakamo wesibini isakhiwo jikelele. Anikezela ufikelelo olusisiseko kulwazi kunye ukuqhagamshela iikhompyutha ukuba kwindawo enye, kummandla okanye kwilizwe. kwinethiwekhi Global computer - asinto isakhiwo lula, elakhiwe ngekhaya kunye nothungelwano corporate, endingowakhe imibutho emininzi abanomdla yokhuseleko data. ukwakhiwa kwawo kungabandakanya ukuya amashumi eziliqela amawaka iikhompyutha ibekwe kwizixeko ezahlukahlukeneyo, amazwe.

Ukuthembeka Internet

Ukubunjwa nayiphi lwembumba kunye womnatha wobulali ibandakanya umncedisi ubuncinane enye Internet kokuba uxhulumaniso abasisigxina World Wide Web nge ikhonkco-high speed. Kuba "buti" imigca abanjalo ukusebenzisa ifayibha enombala, kukho bandwidth 20 Gbit / s nangaphezulu. kwinethiwekhi Global computer - ukuthembeka, ezibonelela amajelo onxibelelwano eliphezulu bandwidth, udityaniso noqhagamshelo amacandelo asekuhlaleni, yengingqi kunye corporate. Umzekelo, i-North American yoMmandla Computer Network (US) elidityaniswe data ezininzi ne-Russia (UR), IsiJapanese (JP) kunye yeYurophu (EU).

Idibanisa kwi Internet

kwinethiwekhi Global computer - kunxulumano ubugcisa ezininzi. imigca unxibelelwano fibre-optic zisetyenziswa ukudibanisa uthungelwano kwindawo yobulali kwi jikelele. Ukuba kude kwaye iingcingo ezihamab phantsi kunzima okanye akunakwenzeka, ngoko usebenzise iintlobo uxhulumaniso ngeengcingo. Ukuba eriyali nokufumana kunye nokuthumela, ngaphakathi komgca emehlweni, ngoko transfer kwedatha kwenziwa ngokusebenzisa amajelo osasazo, kungenjalo esetyenziselwa benikana ulwazi channel satellite. Abasebenzisi ukudibanisa kwi Internet ngoncedo ngababoneleli-nkonzo, leyo ukulungiselela ukusetyenziswa zocingo yodayalo ye-EGPRS. To connect ikhompyutha somsebenzisi ukusuka kwiseva yababoneleli, esebenzisa imodem. Ezi zixhobo edlulisela data ngefomu yedijithali ngeqondo 56 kbit / s. Abasebenzisi bezixhobo eziphathwayo ungakwazi ukudibanisa kwi Internet usebenzisa Wi-Fi. kwinethiwekhi Global computer - ezitshatileyo nje kuphela unxibelelwano iintlobo ezahlukeneyo kunye neenjongo, kodwa ubuchwepheshe.
