I-inthanethi isiyingxenye yempilo yethu yansuku zonke. Ikhula ngokukhulu ukushesha emhlabeni, kodwa hhayi emadolobheni nasemadolobheni kuphela, kodwa nasezindaweni ezikude kakhulu, ezisemaphandleni nasezindaweni ezingafinyeleleki kalula esingazicabanga. Lokhu kungenxa yesidingo esihlala sikhona sokukhulumisana, ukuzithokozisa, ukusebenza kanye nokwenza ezinye izinto eziningi. Kodwa-ke, akwanele nje kuphela ukuba ne-inthanethi, kodwa kuyadingeka futhi ukuba nokuxhumana okuhle nokusheshayo, futhi izindlela ezimbili ezidumile nezisetshenziswa kakhulu kulokhu i-fiber optics ne-ADSL.
Cishe kungokokuqala ukuthi uzwe noma ufunde mayelana ne-fiber optics ne-ADSL. Uma kunjalo, usendaweni efanele, ngoba lapha siyachaza ziyini, zenzelweni, iziphi umehluko wazo omkhulu futhi, ngokusekelwe kulezi, yimuphi ongcono.
Ngaphambi kokuqhathanisa i-fiber optics ne-ADSL, kufanele siqale sichaze lezi zinhlobo ezimbili zokuxhuma ku-inthanethi.
Iyini i-fiber optics?
I-Fiber optics ingenye yezindlela zokuxhuma ezinezintambo ezisetshenziswa kakhulu ezikhathini zamuva nje ngoba imele ukweqa kobuchwepheshe okuvumela isivinini sokudlulisa ukuthi sifinyelelwe lokho, ngokuvamile, iyashesha kunaleyo enikezwa ikhebula le-ADSL. Ngale ndlela, abahlinzeki be-inthanethi abasebenza nge-fiber optics ngokuvamile banikeza i-latency ephansi (i-ping, isikhathi sokuphendula) kanye nomkhawulokudonsa ophezulu nokuncintisana kakhulu, nakuba lokhu kungenjalo ngaso sonke isikhathi, kufanelekile ukuqaphela.
I-Fiber optics ayihlinzeki nje ngokudluliswa kwedatha ye-inthanethi, kodwa futhi Iphinde isetshenziselwe ukunikeza izinsizakalo zocingo, i-TV nokunye. Ngokulandelayo, isebenzisa ama-pulses alula, hhayi kagesi, ukuze ilethe ukwaziswa ngokushesha kakhudlwana futhi ithatha igama layo eqinisweni lokuthi yakhiwe izintambo zefayibha zangaphakathi ezakha ikhebula elilodwa.
Iyini i-ADSL?
I-ADSL ingolunye uhlobo lokuxhumana, njengefiber optics, lusetshenziswa kabanzi, nakuba lobu buchwepheshe busetshenziswa kancane kancane, njengoba inikeza izivinini zokudlulisa eziphansi kakhulu kunefiber optics, kanye neqiniso lokuthi ibanga phakathi kwendawo yokuxhuma namaseva omhlinzeki lithinta isivinini iklayenti esingaba naso.
I-ADSL isebenzisa intambo yocingo ukudlulisa ulwazi. Ikhebula libonakala ngokuba nezintambo zethusi ngaphakathi ezihlukaniswa ngamashaneli okudlulisa amanethiwekhi ocingo kanye ne-inthanethi, ahunyushwa futhi ahlukaniswe idabula, eyaziwa nangokuthi isihlungi esihlukanisayo, esinenjongo yokuhlukanisa amafrikhwensi namashaneli e-inthanethi nocingo.
I-Fiber optics ne-ADSL: lena umehluko wabo omkhulu
Okokuqala, i-fiber optics ubuchwepheshe obusebenzisa intambo njengendlela yokuthutha ulwazi. Lokhu kwakhiwa ngemicu yengilazi kanye nemicu, futhi ngalezi kudlula ama-pulses alula okwenziwa ngawo ukudluliswa kwedatha. Ngenxa yalokhu, i-fiber optics ingafinyelela isivinini sokudlulisa esingaba ngu-600 MB/s kanye nokubambezeleka okuphansi kakhulu, njengoba sesivele sikugqamisile. Ukubambezeleka kungaba ama-millisecond ambalwa nje (ping), futhi akunandaba ukuthi i-fiber efakiwe ikuyiphi indawo yokuxhuma, noma ibanga elingamakhilomitha amaningi; ngokuvamile lokhu akuthinti impendulo yeseva.
I-ADSL, njengoba sesishilo ngenhla, iqukethe intambo yocingo eyenziwe ngezintambo zethusi ngaphakathi. Lokhu akusebenzisi ama-pulses okukhanya, njengoba kwenza i-fiber optics., kodwa idinga ama-pulse kagesi ukuze kudluliswe idatha, engasebenzi kahle futhi eyenza isivinini sokudlulisa, esithathwe kudatha, sibe sifinyelela ku-20 MB/s esiphezulu. Enye into ehlukanisa lobu buchwepheshe ku-fiber optics ukubambezeleka engaziqhayisa ngakho, okuyinto, ngokuvamile, ephakeme futhi ithintwa ibanga, into elimazayo kubadlali abaku-inthanethi abadinga impendulo kanye nokushintshisana kwedatha yama-millisecond ambalwa elilungile udlala isipiliyoni.
Ngakolunye uhlangothi, i-fiber optics yintsha futhi kancane kancane ithatha indawo ye-ADSL, ngakho-ke abahlinzeki be-inthanethi kanye nokuxhumana ngocingo kancane kancane kuya kude nokwakamuva.
Yikuphi okungcono futhi ngani?
Kuleli qophelo, ngomehluko omkhulu osewabalulwe futhi ochazwe ngenhla, akukuningi okufanele kunwetshwe kuwo, ngoba kuyacaca ukuthi i-fiber optics ingcono kunobuchwepheshe be-ADSL. Nokho, asihambe.
I-Fiber optics, njengoba sesazi kakade, inikeza isivinini sokudlulisa esiphezulu kakhulu kune-ADSL. Ngokombono, ingafinyelela isivinini esifinyelela ku-30 izikhathi ze-ADSL, njengoba sinesilinganiso esiphezulu esingu-600 MB/s se-fiber optics kanye no-20 MB/s kokugcina. Lokhu kuletha izinzuzo eziningi ngosuku nosuku, ezibonakala ezikhathini zokulayisha, ezimfushane kakhulu ezinhlelweni ze-fiber optic.
Lena yindlela abasebenzisi abanalobu buchwepheshe obusha abangalanda ngayo okuqukethwe okufana nemidlalo esindayo, izinhlelo zokusebenza ezinkulu namamuvi namavidiyo anokulungiswa kwe-4K endabeni yamasekhondi noma imizuzu embalwa, kuyilapho labo abanoxhumo lwe-ADSL bangathatha imizuzu ukuya emahoreni, nakuba lokho osekushiwo kuhlobene nakanjani nesisindo sefayela okumele lilandwe, kunjalo. Ngokufanayo, i-fiber optics ihlale iwina esigabeni sejubane.
Ngakolunye uhlangothi, sine-latency, elinye lamaphuzu abaluleke kakhulu kwabaningi, ngaphezu kwanoma yini kulabo abavame ukwenza imisebenzi nokusakaza bukhoma, noma ukudlala njalo noma ngezikhathi ezithile, ngoba ukubambezeleka kuhlobene kakhulu nesikhathi. phakathi kwamasistimu, amaseva namakhompyutha. Kuleli qophelo, i-fiber optics nayo iyawina, ngokunikela i-ping ezinzile futhi ephansi engathinteki ibanga, njengejubane lokudlulisa, njengoba ithinteka ekuxhumekeni kwe-ADSL.
