Ingabe uyazi ukuthi inthanethi?

Umnikazi we-computer ayixhunyiwe le Inethiwekhi yomhlabajikelele yama- the Internet kungafaniswa eRobinson: Konke odinga, ngaphezu ukuxhumana nezwe elingaphandle. Manje ukuthi ungakwazi ukufinyelela cishe imfuneko ekusebenzeni kahle ngcondvomshini. Akumangalisi ukuthi inani abanikazi ikhompyutha abafuna ukuxhumeka kunethiwekhi imithombo ngezinkulungwane. Futhi omunye wemibuzo yokuqala lapho udinga ukuqonda ukuthi isheshe itholakale - kuyinto "Uyini-inthanethi." Womabili la magama ungezwakala njalo engxoxweni, "ikhompyutha bokuhlela." Hhayi-ke, ake sibone ukuthi yini inthanethi.

Incazelo elula igama kwakwakhe

Eqinisweni, yonke into ilula: inkampani noma umuntu, ngubani sihlinzeke izinhlelo ukufinyeleleka kwimithombo digital global. Ukukhuluma ngokuthi lokho inthanethi, indlela elula ukusebenzisa isifaniso ngeselula opharetha amaselula. Lezi zinkampani zaziwa kubo bonke (ezifana MTS, Beeline, nokunye.). Ukungena inkontileka amasevisi noma ukuthenga ikhadi le-SIM elifanele, isikhokhelo ithuba ukwenza / ukuthola izingcingo ngokusebenzisa ukuxhumana idivayisi yeselula. Eqinisweni, opharetha ivumela idivayisi ukubhalisa futhi umsebenzi amanethiwekhi zabo engenantambo. It is bonke eyaziwa. Kodwa, ikuphi ukuhlobana okukhona okungenhla, ngombuzo kuyini-ISP? Empeleni, kuba oqondile.

umhlinzeki Inkampani (sikhulume mayelana nomsebenzi ezinkulu) Inthanethi eyenza umsebenzi ofanayo, ukuhlinzeka ukufinyelela kukhompyutha umsebenzisi kunethiwekhi yomhlaba. Maphakathi edolobheni, njengoba umthetho, kukhona into eyodwa noma ngaphezulu izinhlangano ukuthi babe ukucutshungulwa okusezingeni eliphezulu ngakho amandla (ehlukile ikhebula uxhumano, izimiso zesiphuphutheki), bakwazi ukuthatha inani komkhawulokudonsa (gigabits ngomzuzwana) ukuze ezincane izinkampani-abaxhumanisi. ababhalisile Private ixhunywe kwinethiwekhi kuyinto emahhovisi osizayo.

Kuhle Umhlinzeki Wesevisi Ye-inthanethi

Ukunquma ukuxhuma kwi-Inthanethi edolobheni elikhulu, umsebenzisi ikhompyutha ebhekene inala izipesheli ezivela ezinkampanini ezahlukene. Ngamunye wabo, ukuheha amehlo, inikeza izici zayo siqu: kungaba "ibhonasi" ngesimo khulula IP-TV, ohlelweni isaphulelo, intengo ezinhle, ukufinyelela ngesivinini noma ukukhuthazwa ngenxa ukukhangisa izixhumanisi zazo. Tshela okuyinto umhlinzeki ngokuhle kunakho konke kwawo, akunakwenzeka, njengoba umsebenzisi ngamunye izidingo zabo nezifiso.

Ngakho, enye owanelisekile eziphansi imali plan ngesivinini 5-10 Mbps, kuyilapho ezinye Mbps 100 futhi kubonakala kancane. Kodwa ukuphatheka umsebenzisi lwesithathu kubalulekile, kungani ethanda inkampani usebenzisa imishini uxhumano nomsebenzisi ikhompyutha akuyona ikhebula, futhi imvamisa radio. Qaphela ukuthi inethiwekhi kukhona izingosi eziningi lapho ungabona phezulu abanikezeli besevisi internet ethize ezweni / esifundeni / ndawo. Abakwazi ukusebenzisa idatha uma kwenzeka ukuthi kumelwe sikhethe phakathi nezinkampani eziningi nezimo ezifanayo (isivinini, intengo, izinga). Mhlawumbe, kufanele aveze ukuthi okwesikhathi umile Computing uhlelo manje akukhetha kakhulu ukukhetha umhlinzeki lebhokisi ikhompyutha obhalisele imishini yayo ngosizo optical zokuxhumana imigqa. Okunjalo isixazululo ivumela ukunciphisa ukubambezeleka isignali transmission, kanye futhi ukuthathelwa umshuwalense ngokumelene overvoltages ezibaliwe uma kuduma izulu.
