Izinhlobo zoxhumano lwe-intanethi zitholakala ku-Network Networking
Njengomninikhaya (noma umqashi), cishe unamathuba amaningana wokuthi ungaxhuma kanjani ku-Inthanethi. Indlela yokuxhumeka oyikhethayo ithinta indlela inethiwekhi yendlu okumelwe ihlelwe ngayo ukusekela ukwabelana kwenethiwekhi ye-intanethi. Okunye okunye ukuxhumeka kwenethiwekhi ye-intanethi kuchazwe lapha.
I-DSL - I-Digital Subscriber Line
I-DSL ingenye yezinhlobo ezivame kakhulu zokuxhumeka kwe-intanethi. I-DSL inikeza inethiwekhi ye-speed speed phezu kwemigqa ejwayelekile yefoni usebenzisa i-modem ye-digital. Ukuhlanganyela kokuxhumeka kwe-DSL kungafinyeleleka kalula ngezingcingo ezihamba ngocingo noma ezingenantambo.
Kwamanye amazwe, isevisi ye-DSL nayo yaziwa nangokuthi i- ADSL , i- ADSL2 noma i- ADSL2 + .
I-Cable - I-Cable Modem Inthanethi
Njenge-DSL, i- modem yekhebula yindlela yokuxhumeka kwe- intanethi ye-broadband. I-Cable ye-Internet isebenzisa ama-cable amakhemikhali ekhebula kunomgwaqo, kodwa ama-router efanayo afana ne-DSL Internet uxhumano nawo asebenza ngekhebula.
I-Cable Internet iyaziwa kakhulu kune-DSL e-United States, kodwa emazweni amaningi amaningi, ukuhlanekezela kuyiqiniso.
I-Inthanethi Yokudayela
Uma ngabe izinga lomhlaba lokuxhumanisa kwenethiwekhi ye-inthanethi, ukudayela ngokuphambene kushintshwa kancane kancane ngezinketho eziphakeme kakhulu. Ukudayela kusetshenziswa imigqa ejwayelekile yocingo kodwa, ngokungafani ne-DSL, uxhumano lwe-dial-up luthatha ucingo, luvimbele izingcingo zezwi ngesikhathi esisodwa.
Iningi lamanethiwekhi asekhaya asebenzisa izixazululo ze- Inthanethi Yokuxhuma (ICS) nge-intanethi ye-dial-up. Ama-router wokudayela ayinzima ukuthola, abiza, futhi, ngokuvamile, akwenzi kahle anikezwa ipayipi le-intanethi elincane.
Ukudayela okuvame ukusetshenziswa kakhulu ezindaweni ezingaphansi kwezindawo lapho amasevisi we-cable ne-DSL Internet engekho. Abahambi kanye nalabo abanamasevisi e-intanethi angathembekile basebenzisa ukudayela njengendlela yokufinyelela yesibili eqinile.
I-ISDN - Inethiwekhi Yedijithali Yesevisi Ehlanganisiwe
Ngama-1990, i-ISDN Inthanethi yakhonza amakhasimende amaningi afuna inkonzo efana ne-DSL ngaphambi kokuba i-DSL ibe khona kakhulu. I-ISD isebenza emigqeni yocingo futhi i-DSL isekela ithrekhi yomsindo kanye nedatha kanyekanye. Ukwengeza, i-ISDN inikeza izikhathi ezimbili kuya kwezingu-3 ukusebenza kokuxhumana okuningi kokudayela. Ukuxhumana nge-Home ne-ISDN kusebenza ngokufanayo ukuze kuthungelwano ngokudayela.
Ngenxa yezindleko eziphakeme kakhulu nokusebenza okuphansi uma kuqhathaniswa ne-DSL, i-ISDN yanamuhla iyisisombululo esiwusizo kulabo abafuna ukucindezela ukusebenza okwengeziwe emigqeni yabo yefoni lapho i-DSL ingatholakali khona.
I-Satellite Internet
Amabhizinisi afana ne-Starband, Direcway, ne-Wildblue anikeza isevisi ye-intanethi ye-satellite. Ngesidlo samaminithi esingaphandle esingaphandle futhi i-modem yedivaysi yedala ngaphakathi kwekhaya, uxhumano lwe-inthanethi lungasungulwa phezu kwesixhumanisi se-satellite esifana nezinsizakalo zethelevishini zesathelayithi.
I-Satellite ye-Satellite ingaba yinkinga enkulu kunethiwekhi. Amamodeli wesathelayithi angase asebenze ngamabhurogi wokubambisana, futhi amanye amasevisi e-intanethi afana ne-VPN namageyimu we-intanethi angeke asebenze ngaphezu kokuxhumana kwe-satellite .
Ababhalisile kumasevisi e-intanethi ye-satellite ngokuvamile bafuna ukufika komkhawulokudonsa okutholakala kakhulu ezindaweni lapho ikhebula ne-DSL ayitholakali khona.
I-BPL - I-Broadband Over Power Line
I-BPL isekela uxhumano lwe-Intanethi kumigqa yamandla okuhlala. Ubuchwepheshe obusuka emgqeni wamandla we-BPL usebenza ngendlela efanayo nomugqa wefoni DSL, usebenzisa isikhala sokusayina esingasetshenziswanga kwikhompyutha ukuze uthumele umgwaqo we-Inthanethi. Noma kunjalo, i-BPL iyinkinga yokuxhumeka kwe-inthanethi. Izimpawu ze-BPL zenza ukuphazanyiswa okuphawulekayo eduze kwemigqa yamandla, okuthinta ezinye iziteshi zomsakazo ezinelayisensi. I-BPL idinga imishini ekhethekile (kodwa engabizi) ukujoyina kwinethiwekhi yendlu.
Ungangqubuzani ne-BPL ngezingcingo ezibizwa nge- powerline home networking . Ukuxhumana nge-Powerline kusetha inethiwekhi yendawo yekhompuyutha ngaphakathi kwendlu kepha ayifinyeleleki ku-intanethi. I-BPL, ngakolunye uhlangothi, ifinyelela kumhlinzeki wezinsizakalo ze- intanethi ngaphezu kwemigqa yamandla kagesi.
(Ngokufanayo, okuthiwa i- network line home networking igcina inethiwekhi yendawo yasendaweni phezu kwemigqa yefoni kepha ayinweli kuxhumano lwe-intanethi ye-DSL, ISDN noma isevisi yokudayela.)
Amanye amafomu okuxhumana kwe-intanethi
Eqinisweni, ezinye izinhlobo eziningana zokuxhumeka kwe-Intanethi azikakhulunywa. Ngezansi isifinyeto esifushane sezinketho zokugcina ezisele:
- I-Intanethi ye-T1 / T3 ye-Fractional - T1 ne-T3 yilawo amagama amafemu ezokuxhumana ahlinzekwe ukuqasha izintambo zenethiwekhi. Ifakwe kwezinye izindawo zokuhlala ezihlala ezindaweni eziningi, imigqa engxenyeni ye-T1 / T3 yilezi zinkimbinkimbi ezingaphansi komhlaba ezixhuma ngqo kumhlinzeki wensizakalo, ngokuxhumana komuntu ngabanye kushintshela izintambo ze-Ethernet.
- I-Intanethi ye-Intanethi - Ukuxhumeka kwe-intanethi ye-Intanethi kungenziwa ngaphezu kwamafoni omakhalekhukhwini . Ngenxa yezindleko eziphakeme, i-intanethi yeselula izosetshenziselwa kuphela emakhaya ngesikhathi sephuthumayo.
- I-intanethi ye-Broadband ye-Intanethi - I- WiMax technology isekela i-intanethi ye-intanethi esheshayo ngezikhungo eziyisisekelo ezifana namanethiwekhi weselula. Amanethiwekhi okuthiwa i-WiFi noma ama-"mesh" enza umsebenzi ofanayo usebenzisa ubuchwepheshe obuhlukile.
