Inthanethi - I-World Wide Web

Futhi okungukuthi i-Internet? Ungachaza ngewakho Ngamafuphi, yini empeleni yayo ngokomzimba of kuyini lokho? Njengoba umoya kunjalo futhi kulula: ingxube oksijini nitrogen. Kuyini i-Internet?

Okokuqala, ake ukucacisa ukuthi bangaki abantu abayozuza zalesi simo. Abasebenzisi be-intanethi hhayi kuphela izigidi zabantu kanye nezigidigidi - cishe ingxenye yabo bonke abantu emhlabeni. Kungaqondakala ngezwi Inthanethi World Wide Web ngolwazi okungukuthi amaseva etholakalayo - computer anamandla, iwashi ungaxhumekile kuwebhu.

Inthanethi wazalwa ngo-1969 ngenxa kweyishumi umsebenzi ososayensi American ukudalwa uhlelo zokuxhumana uma impi ticondziso kanye inkece uhulumeni wase-US. Isikhathi ukuxhumana kokuqala phakathi amanyuvesi amabili, lapho wayiswa mbalwa zwi kubhekwa usuku lokuzalwa kwe-inthanethi.

Esikhathini yoma wabalwa ekuseni owasungula le imeyili yokuqala electronic, okuyinto ngokushesha waqala ukuthandwa. Ngu amanethiwekhi axhunyiwe kwamanye amazwe, futhi kwaba ngamazwe. Nokho, inethiwekhi lokuqala, elalingaba igama ARPANET, wayemiselwe ukuba afele ukuncintisana nenye inethiwekhi, okuyinto ngo-1984 wasungula National Science Foundation. Inethiwekhi entsha ibe-bandwidth mkhulu, futhi ngo-1990 i-ARPANET abasekho.

Esikhathini 90 zokuqala kuwebhu emhlabeni wonke iba yomphakathi, isiphequluli sewebhu wokuqala yasungulwa, futhi kusukela ngaleso sikhathi-Inthanethi Kancani-kancani ikhula. Futhi ekukhuleni kwayo ngempela umxhwele: ngesilinganiso ukwanda izilaleli Inthanethi izikhathi ezimbili ephakeme kunaleyo izinga wokukhuphuka ezithamelini cable ithelevishini, kathathu - ithelevishini futhi izikhathi 8 - umsakazo.

Inthanethi siqukethe amanethiwekhi eziningi ezahlukene, kuhlanganiswe ndawonye ngokusebenzisa umthetho olandelwayo we-IP kanye nezimiso packet data umzila. Noma yimuphi yenkampani, zezemfundo, uhulumeni noma inethiwekhi ekhaya ithumela idatha, kanye eslphambanweni lezi inethiwekhi imizila ekhethekile ukuthumela idatha ku-lesifanele IP-ikheli.

I-Internet-Russian wazalwa e-Institute of Atomic Energy, futhi ngo-1990 inethiwekhi Russian ixhunywe emhlabeni. Ngawo lowo nyaka ke yabhaliswa esiphezulu lesizinda .su. Ngo-1994 kwabonakala sengathi le .ru lesizinda, futhi ngo-2010 - .rf.

I-intanethi ayinaye umnikazi olulodwa, ngoba kuletha ndawonye inethiwekhi emazweni amaningi. Ngesizathu esifanayo ngeke avalwe ngokuphelele phansi. I-intanethi ngokuqondene ukutholakala isethi yayo jikelele, kokubili izici eziyingozi futhi ewusizo. I-Internet isetshenziselwa zokuxhumana, dating, imininingwane ukubuyiswa, ukudluliswa kanye storage of idatha. Osomabhizinisi zisebenzisa internet ukwenza imali, i-nabakhwabanisi - ukweba imininingwane, ukuphanga, ukuhlaselwa, njll

Ngo-2011, kwathiwa ngokusemthethweni evunywe umuntu unelungelo lokusebenzisa i-Internet, ukuze umkhawulo wokufinyelela othile inethiwekhi kuyicala indiva amalungelo abantu.

Namuhla, izinkampani ezinkulu hhayi kuphela, kodwa amafemu amancane kakhulu babe kumawebhusayithi abo. Ibhizinisi zokukhiqiza ukukhuthazwa kumasayithi e-internethi okhula ngesivinini. Akunakwenzeka ukuba ukucabanga iphrojekthi ukuthengisa ngeke asebenzise i-Internet izinjongo zabo, kusukela ukuxhumana yenkampani, kusebentisana kwemibhalo namakhasimende kanye wonke amaphrojekthi, ehunyushwe ngokuqondile ku-intanethi.

Kuvamile ukuthola abantu abangafuni ukuya emsebenzini, kanye nomsebenzi ekhaya inthanethi. Ukuze nomholo e-inthanethi kukhona amathuba amaningi kangaka ngenxa ekukhuleni kwayo engaguquki is nesidingo Ochwepheshe, ukukhonza ezihlukahlukene izindawo umsebenzi e inethiwekhi.
