Kwaye uyazi njani i-Internet?

Njani na i Internet? Interesting nyaniso: I-Internet kwakuvela kuphela ngexesha Cold War njenge uhlobo project Umbutho wophando zomkhosi US ebizwa ARPA. Developers lwamiselwa ukuba ezinye iindlela zobugcisa uqhagamshelo iikhompyutha zomkhosi ukuze network laqhubeka ukusebenza kwayo elichanekileyo kwanaxa kukho imfazwe yenyukliya okanye Kucinywe kakhulu kwiindawo zonxibelelwano. Yethopholoji efanayo ebizwa "inkwenkwezi" wenqaba nangoko, inethiwekhi ukuba zakhiwe, kodwa ukuba wehla esiludumbo engundoqo, yayiza uqhagamshelwano ezilahlekileyo nenethwekhi wayeza kuyeka ukusebenza. Kwakhona kwaba Akwenzeki ukuxhulumana ikhompyutha nganye ngoncedo lwelayini ngamnye, ngenxa yokuba izixhobo ezininzi kakhulu kuya kufuneka ukuyisebenzisa.

Abaphandi baye bachitha ixesha elininzi, kodwa nako ukufumana isisombululo lamaqhinga kule ngxaki. Nantso into awayenzayo ukuba: Qhagamshela ikhompyutha yakho kwinethiwekhi eziyelelene nabo omnye komnye imijelo yonxibelelwano eziliqela. Kulo mzekelo, ulwazi idluliselwe kwi-iipakethi network (oko kukuthi, izahlulo) phakathi kwiindawo amakishiweyo. Elinye lawo iphakheji iqulethe yonke inkcazelo malunga uya khona kwaye uhamba ngqo ukuya wokukora welinye esiludumbo, ngaloo ndlela isiphumo imfutshane endleleni. Kwimeko apho ijelo lonxibelelwano, okwaye kwabonelela ndlela imfutshane, iye abakhubazekileyo okanye baphola, ulwazi waye, elide, kodwa ngendlela eyahlukileyo esebenzayo abasebenze ngokuchanekileyo. Kodwa ke ukugqithisela ibalulekileyo kule modeli - kukho iziko yolawulo, ngoko nozihlisela kwaba nzima kakhulu kwaye kube nzima yonke le nkqubo. Ukuba kukho umntu ocela indlela i Internet, ngoko unga ukuphendula ngokukhuselekileyo - njenge web yesigcawu.

Emva kwexesha, ukuba loo womnatha afakelwe US kwiiyunivesithi, ngubani abathe ngexesha lesifundo yokhuselo technology, ngoko Imibutho e sethi kumazwe, emva kwabo, kwaye ezahlukeneyo nezorhwebo nemibutho. Broadband ndiloyisile ihlabathi liphela ngendlela elula kunye lula ulwazi lonaniso.

Kungenxa lunatyiswe isakhiwo kunye nokungabikho iziko engundoqo yolawulo "ubulembu" World Wide Web iye uthandwa kangaka. Okwangoku, akukho namnye yaphuhliswa ilizwe ukuba akasebenzisi zonke izinto zayo, kodwa ke ukuba le nkqubo wayenazo into engundoqo, ukuba ungabi iprojekthi enjalo abanomdla nabani.

Ngapha koko, xa sihlalutya: into ibiya nokuphuhlisa lwangaphakathi uthungelwano computer, ukuba oosomashishini okhuphisana nabo babe nangxaki ukuqonda indlela Internet, ukufumana kude ukucima yonke ezingundoqo incapacitate. Kulo mzekelo, le nkampani yingozi ukuyeka amaxesha zemveliso kunye nokwaphuka, kule meko ecaleni okubi - le ukuvuza ingcaciso eyimfihlo.

Umzekelo ibonisa ukungawi intanethi web mihla; ngexesha US kulwa Iraq, eUnited States wazama khubaza okanye athintele ukufikelela intanethi ukuya Iraqis. Oko kuyo? Yekani. Nangona imizimba neququzelela umsebenzi womnatha yonke, zifumaneka eMelika.

inzuzo elandelayo Internet - ixabiso. Networking inika ngeteknoloji entsha, leyo banike ixabiso elisezantsi yale nkonzo kumazwe amaninzi.

I-Internet kubizwa yenziwe random, elo ezingenzelwanga ukuba zityiwe loluntu onke amaqela abantu kumazwe amaninzi ehlabathini lonke. Yakhe baduma zuza nto ekunyaniseni, banality kwanenyaniso indlela i Internet: Akukho ngundoqo olawula zonke iinkqubo - kungabikho ngxaki. Ngaphezu koko, abantu abaninzi, xa beza kuphumla, qiniseka ukuba ukuhlola ukuba ingaba banazo na ehotele ukufikelela Internet, ukuze bakwazi ukunxibelelana kunye nosapho kunye nabahlobo babo.
