I ngesivinini esiphezulu kwi-Inthanethi, ahlinzekwa ngaphakathi ubuchwepheshe besimanje

Omunye wemibuzo obonakala ulula, lapho kungekho impendulo eqondile ngendlela elandelayo: "Uyini ngesivinini esiphezulu digital ukushintshanisa kwe-data phakathi izinhlelo ezimbili khompyutha?" Ngokwesibonelo, kuyaziwa ukuthi kohlaka amathekhiniki Japanese of zokuhlola ukudluliswa kwedatha iye okuvela phakathi kwamakhompyutha ngesivinini terabytes engaphezu kwemibili ngomzuzwana (20 terabits ngayinye 2012). Nokho, izindleko ekusebenziseni ikhambi elinjalo siphezulu kakhulu, okuyinto ayenzi abezindaba ubuchwepheshe. yalokho okuhle njalo is eziningi ezikhethekile kwekhompuyutha futhi imishini inethiwekhi prototypes. I abavamile abanikazi ikhompyutha banesithakazelo kakhulu ezintweni umbuzo uyini ngesivinini esiphezulu kwi-Inthanethi, ohlongozwayo ngandlela-thile umhlinzeki.

kudingeka

Umthamo yesimanje amaphakheji software amafayela soxhumanoningi liyakhula ngesilinganiso okuhle ngendlela engakholeki. Ngokwesibonelo, uma ukusatshalaliswa kohlelo Windows XP eyaziwa ezisebenza ubekwe indinganiso 700MB CD, izinguqulo ezalandela zidinga DVD (ingxenye noma ngokuphelele). Kusobala ukuthi ukuze sinciphise isikhathi esichithwa ukudluliswa kwedatha , ijubane esiphezulu inethiwekhi ukuba lenyuke. Kungenjalo, umsebenzi nge eziningi inethiwekhi imithombo bangaba ukulindelwa okuqinile beqeda inqubo yokudlulisa.

ADSL Isivinini

Obunye ubuchwepheshe, okuyinto namanje kabanzi kwabanye abasebenzisi, lena ADSL. Kuyinto uhlobo loxhumano ukuthuthukiswa-dial-up. Isebenzisa ngocingo ekhona. PBX umhlinzeki ukusetha idivayisi ekhethekile - DSLAM. Subscriber wona uxhuma computer imodemu ezifanele. DSLAM kuyinto phakathi exchange futhi imishini zokubhalisa. Kuqhathaniswa ezikhethekile ikhebula izixazululo inzuzo ukuthi uma une ifoni yasendlini, futhi umhlinzeki ezifanele, i-Inthanethi uxhumano kungaba kwenziwe ngokushesha ngangokunokwenzeka.

I ngesivinini esiphezulu isinqumo esinjalo incike izici umugqa, uhlele bese imishini amakhono. Ngakho, i-ADSL ejwayelekile ITU G.992.1 Isijobelelo A (B) «uphahla" isivinini lomjovo Mbps 12, kanye nezinzuzo - 1.3 Mbps (isiteshi njalo indlela). Kodwa i ngcono isixazululo ADSL2 + (Imodi ITU G.992.5 Isijobelelo M) likhuphuke 24 / 3.5 Mbps, ngokulandelana. Iningi abasebenzisi ekhaya bangathembela 8/1 Mbps kakhulu.

Analogue yezintambo

Okwamanje, izixazululo ethandwa kakhudlwana ngesisekelo pair ezisontekile nezixhumanisi optical. Esimweni sokuqala, babashayeli Ithusi idatha ikhebula adluliswa ngamazinga kuze kube Mbps 100. Gigabit ngesivinini kutholakale kubasebenzisi abavamile akuvami ukuba eziphoqelelwe umkhawulo ubude ingxenye ikhebula kusukela dispenser kwikhompyutha zokubhalisa. eyinkimbinkimbi Okuningi umugqa wadala ngesisekelo imigqa optical bangadlulisela eduze fibre okungenani 10 GB kwemininingwane, futhi banikezwe kungenzeka titibonelo letinkhulu tekuvumelana inani iziteshi kwelinye fibre, inani sokudlulisa izinga lingalinganiswa terabits. Uma uxhuma kunoma fibre optic amanethiwekhi ngokuvamile olunikezwa umsebenzisi 100 megabits ukuba 1 Gigabit.

link engenantambo

Siyabonga ekwandeni kumadivayisi ephathekayo zokuxhumana ngentshisekelo abaningi okukhethekile kwakungokokuqala pose umbuzo uyini ngesivinini esiphezulu-Wi-Fi. Okwamanje kukuwe Mbps 140 (ngisho amadivayisi 802.11n kushiwo 300 Mbit / s). umthelela omkhulu ijubane amakhono zokuxhumana ezingenazo izintambo imigqa kudingeka babhekane nezithiyo (izindonga, njll) Ingabe phakathi amadivaysi.
