Ikhompyutha inethiwekhi Global - kuyinto exchange onokwethenjelwa wokwaziswa nsuku zonke

Ezweni abantu abayizinkulungwane zezigidi zisebenzisa amasevisi ulwazi imithombo, enganikeza global ulwazi kwikhompyutha inethiwekhi. amakhompyutha exhunywe kwi-Inthanethi Okuningi kwezigidi ezingu-150 ukugcina omningi ulwazi. Ukwakha i-Inthanethi kuholele isidingo ukudala eyodwa ulwazi isikhala, ngaphandle okuyinto manje Awukwazi ukwenza inhlangano noma iyiphi abasebenzi oyedwa '.

Isakhiwo inethiwekhi yekhompyutha global

Inthanethi uxhuma abasebenzisi:

• wendawo;
• zesifunda;
• yezinkampani.

Izinga lokuqala isakhiwo global kwakwakhe - sendawo, okuyizinto amanethiwekhi zezakhiwo, amahhovisi, lapho inqwaba eziningana amakhompyutha ehlangana ematfuba etindlela tekutfola lwati. amanethiwekhi okunjalo ngeke likwazi ukunikeza ukufinyelela idatha yomsebenzisi zitholakala ezindaweni ezihlukene edolobheni. amanethiwekhi Regional - lizinga isakhiwo global yesibili. Zinikeza ukungena kokukude ulwazi kanye ukuxhuma amakhompyutha ngaphakathi endaweni eyodwa, esifundeni noma izwe ukuthi. inethiwekhi ikhompyutha Global - akulona uhlaka lwe lula, okuyinto yakhiwa futhi amanethiwekhi yenkampani, okuqondene izinhlangano eziningi abanesithakazelo sokuvikela idatha. Ukwakheka yabo ingase ihlanganise kuze kube amashumi amaningana ezinkulungwane amakhompyutha etholakala emadolobheni ahlukahlukene, amazwe.

Ukuthembeka Inthanethi

Ukwakheka iyiphi ezinkampani inethiwekhi yendawo kuhlanganisa okungenani oyedwa iseva Inthanethi kokuba uxhumano unomphela kwi-World Wide Web ngesixhumanisi ngesivinini. Ukuze uthole "isiqu" imigqa enjalo njalo zisebenzisa fibre optical, has a komkhawulokudonsa of 20 Gbit / s nangaphezulu. inethiwekhi Global ikhompyutha - nokwethenjelwa, okunikeza neziteshi ukuxhumana okusezingeni eliphezulu bandwidth, ngokuxhumanisa izingxenye endaweni, esifundeni yenkampani. Ngokwesibonelo, North American Regional Computer Network (US) ixhunywe amaningi idatha izixhumanisi nge-Russia (RU), isi-Japanese (JP) kanye European (EU).

Ixhuma ku-inthanethi

inethiwekhi ikhompyutha Global - inhlangano ubuchwepheshe amaningi. Fiber-optic zokuxhumana imigqa asetshenziswa kuchunywa endaweni amanethiwekhi zendawo kanye emhlabeni jikelele. Uma kunjalo kude kanye cabling kunzima noma kungenakwenzeka, bese usebenzisa uxhumano izinhlobo engenantambo. Uma-antenna useyayamukela bese bedlulisela, kukhona ngaphakathi umugqa obonayo, ukudluliswa kwedatha ke kungaba kwenziwe ngokusebenzisa amashaneli omsakazo, kungenjalo esetshenziselwa ukushintshisana Imininingwane satellite siteshi. Abasebenzisi ukuxhuma kwi-Inthanethi ngosizo abahlinzeka ngemisebenzi, okunikeza ukusetshenziswa yokudayela ngocingo. Ukuze uxhume ikhompyutha yomsebenzisi kusuka kwiseva yomhlinzeki, usebenzisa modems. Lezi amadivayisi ukudlulisa idatha efomini yedijithali ngesilinganiso 56 kbit / s. Abasebenzisi amadivayisi ephathekayo kungaba ukuxhuma kwi-Inthanethi usebenzisa i-Wi-Fi. inethiwekhi ikhompyutha Global - akuyona nje inyunyana amanethiwekhi ezahlukene kanye nezinjongo, kodwa futhi ubuchwepheshe.
