Kuyini World Wide Web?

Umuntu namuhla akusho cabanga ngokwayo ngaphandle internet. Kodwa abaningi abazi ukuthi empeleni - World Wide Web. Isifinyezo se-WWW, noma ibinzana World Wide Web, e izwi nezwi kuzwakala "inethiwekhi ukuthi ihlanganisa umhlaba wonke." Ngakho, lokho-inthanethi nekutsi isebenta njani? Okokuqala nje, kuliqiniso, Network. Kuhlanganisa izingxenye eziningi ezahlukene, ezifana nezokuxhumana, izingxenye, imishini, izingxenye, nokuningi. Konke lokhu ikuvumela ukuthumela kanye nokwabelana ngolwazi.

Lapho uqala akha Inthanethi global, iqembu engumthengisi nanolwazi kule ndawo ochwepheshe uhlelo kahle imithetho lakhiwe ngokuba ukudluliswa kolwazi. Khona-ke kulesi simiso ngokuthi yezifiso. Basuke olwamukelwa kuwo wonke umhlaba, futhi idatha ku inethiwekhi kuphela labo yezifiso. Isebenza kanjani? Lonke ulwazi, kungakhathaliseki ingcaca, umbhalo, ividiyo noma ulwazi Umsindo ufakwe ngendlela ekhethekile, idluliselwa ku-intanethi, futhi umsebenzisi ubona has ukuqopha ulwazi oluthunyelwe ku-ke umamukeli. I-World Wide Web has yezifiso ezahlukene futhi kuncike kulokho izinhlelo nemisebenzi sisebenzisa uma usebenza kuwo. ICQ noma i-Skype uma usebenzisa izinhlelo, ubuka amawebhusayithi noma umsebenzi nge-e-mail - konke lokhu kukhona yezifiso ezahlukene kanye nolwazi idluliselwa ngefomethi onomfutho noma ngekhodi. Le mibiko, esikhundleni salokho, bakha isethi eyodwa ngokuthi TCP / IP.

I-World Wide Web futhi inikeza wonke amakhompyutha wakho nenethiwekhi amakheli abo noma IP. Okusho ukuthi, ngokushesha ngangokunokwenzeka ukuxhuma kwi-Inthanethi, uzonikezwa ikheli.

Lwenza namanye amaseva namakhompyutha nazo axhumene kunethiwekhi ukuze siqaphele ikhompyutha yakho kusuka ezihlukahlukene abanye. Idivayisi yakho, esikhundleni salokho, sibonga kuleli kheli ungakwazi ukwaba namanye amaseva, futhi ngayinye kuwo ngokuhlukana.

Uma omunye umuntu ucabanga ukuthi ukudluliswa kolwazi zingadida ke wenza iphutha. Ngemva Umhlaba Network esabela computer ngamunye IP yayo ehlukileko. I-computer ngaphandle IP alikwazi ukuba abahlanganyeli agcwele e enethiwekhi basebenzise amasevisi ayo. Ngokwesibonelo, ngeke ukwazi ukuthumela noma ukuthola i-imeyili, upheqa isayithi ofuna, njll

Awekho ma-elementi kancane ebalulekile inethiwekhi global kukhona amasayithi. Nokho, ngenxa yokuthi ikheli le-IP yakhiwa izinombolo, ngekhanda kube nzima umsebenzisi elula. Ukuze wenze lokhu, uhlelo yasungulwa amagama DNS, okuvumela amasayithi ukunikeza amagama, ijwayelekile digital IP ayetha amehlo ethu.

Ngakho, ake fingqa ucwaningo lwethu. World Wide Web - wonke amakhompyutha elixhunywe kuso ngokusebenzisa ikheli inethiwekhi siqu. Ukuxhumana senzeka phakathi kwawo ngokuvumelana nezimiso eziqondile - yezifiso. Ukuze imisebenzi ehlukene zisebenzisa yezifiso ezahlukene. Yonke idatha ngocansi kuyi-Internet e ifomu ngekhodi. Konke lokhu okwenzekayo ezingeni hardware futhi esobala ngokuphelele umsebenzisi, abangakwazi ukuthumela futhi wamukele idatha ngefomethi ajwayelekile.
