Kodi ukadaulo wa ADSL ndi chiyani ndipo umagwira bwanji?

ADSL ndichidule cha Asymmetric Digital Subscriber Line

(Wolembetsa wa Asymmetric Digital)

Ndi ntchito yomwe imapereka intaneti yolumikizira yolumikizira.

Ndiwo njira yolumikizana kwambiri ya DSL yomwe imagwiritsa ntchito mawaya omwe adayikidwapo kale kuti agwiritse ntchito foni ndipo izi zimapangitsa kukhala njira yotsika mtengo komanso yothandiza kugawa kulumikizidwa kwa intaneti kunyumba, makamaka chifukwa imathamanga kwambiri maulendo 30-40 mwachangu kuposa chikhalidwe dial-up modem yolumikizira, ndipo imagwiritsa ntchito ma frequency osiyanasiyana.

Muukadaulo wa ADSL palibe chindapusa malinga ndi nthawi kapena zolipira zilizonse zolumikizirana kuti zitha kutchedwa ukadaulo wanthawi zonse, pomwe kompyuta imatha kulumikizidwa kwathunthu ku intaneti kudzera pa chipangizo cha ADSL kapena modem ya burodibandi.

Mfundo yogwirira ntchito ya ADSL

Mfundo zaukadaulo wa ADSL ndizosavuta ndipo zimakhudza kupititsa deta kudzera pagawo lamkuwa lamtundu winawake;

Ndiye kuti, waya wamkuwa uli ndi mphamvu zochulukirapo kuposa momwe umagwiritsidwira ntchito pama foni okha, ndiye ADSL imagwiritsa ntchito malo owonjezerawa ndikugawa kuchuluka kwakanthawi mkati mwa zingwe zamkuwa m'magawo atatu.

Gawo loyamba la waya wamkuwa ndi ma frequency omwe amagwiritsidwa ntchito poyimbira foni kuyambira 300 mpaka 3400 Hz, yomwe imadziwika kuti POT (Plain Old Telefoni) ndipo imasiyanitsidwa kwathunthu ndi mbali zina ziwiri za waya wamkuwa pogwiritsa ntchito chida chapadera chodulira imathandizira kuyendetsa bwino kwa kukambirana patelefoni ngati kulumikizana kwa ADSL kuyima pazifukwa zilizonse.

Pomwe gawo lachiwiri la waya wamkuwa ndi njira yotumizira deta, yomwe imadzipereka kutumiza deta kuchokera kwa wogwiritsa ntchito kupita ku netiweki, kapena zomwe zimatchedwa kuti download,

Gawo lachitatu la waya wamkuwa ndikutsitsa, mwachitsanzo, kuchokera pa netiweki kupita kwa wogwiritsa ntchito, ndipo ziyenera kudziwika pano kuti liwiro lotsitsa kuchokera pa netiweki mumizere ya ASDL ndilokwera kwambiri kuposa liwiro lakukweza pa netiweki ndipo izi ndi zomwe mawu asymmetric amatanthauza.

Kodi mawonekedwe a ADSL ndi ati?

● Makina opatukana a ADSL ndi othandiza komanso othandiza.Mutha kusefukira pa intaneti uku mukuyimba foni osadukiza njira ziwirizi.

● Ndiukadaulo wolumikizana ndi point-to-point, kutanthauza kuti kulumikizana kwanu kumakhazikika ndipo sikukhudzidwa ndi chilichonse bola ngati wogwiritsa ntchito intaneti saleka kugwira ntchito.

● ADSL imakupatsani intaneti yabwino poyerekeza ndi ISDN kapena kulumikizana ndi modem. Ndi ADSL, mutha kutsitsa zikalata ndi masamba ndikutumiza imelo mwachangu.Mutha kuwona kapena kutumiza mafayilo amawu ndi makanema mwachangu kwambiri. Telefoni pa intaneti itha kukhala kudzera pa ADSL.Zothandiza kwambiri kumakampani kuti achepetse mtengo wamafoni apadziko lonse lapansi.

● Pogwiritsira ntchito ntchitoyi, simudzadandaula za ndalama zowonjezera kapena ndalama zina zilizonse zomwe mungalandire, pamakhala ndalama zolipirira pamwezi zomwe muyenera kulipira ndipo ndizokhazo, popanda kuchuluka kwa zomwe mumagwiritsa ntchito pa intaneti zikusokoneza ndi ndalama zomwe muyenera kulipira.

Kodi zovuta za ADSL ndi ziti?

Ngakhale zabwino za ntchito yayikuluyi, sizikhala zopanda zovuta zina, zomwe tidzatchula, zomwe ndi:

● Kuthamanga kwa kulumikizana kwanu kwa ADSL kumakhudzidwa ndimtunda wanu kuchokera kumalo olandirira matelefoni, kutalika kwake, kumakhala kofooka. Izi zimapangitsa ADSL kukhala yosayenera kugwiritsidwa ntchito kumadera akumidzi, komwe sikupezeka kawirikawiri, ndipo ngati ikupezeka nthawi zambiri imakhala yosauka.

● Ukadaulo wa ADSL umakhudzidwanso ndi kuchuluka kwa anthu omwe akugwiritsa ntchito mzere wanu, ndipo ngati pali anthu ambiri pakhoza kukhala kuchepa koonekera, makamaka ngati oyandikana nawo alinso ndi ADSL ndipo amalembetsa mwachangu.

● Kuthamanga kwa kutsitsa kuchokera pa netiweki ndikokulirapo kuposa kuthamanga kwa netiweki, chifukwa izi zitha kuonedwa ngati zoyipa zazikulu kwa anthu omwe amatumiza mafayilo nthawi zonse pa netiweki, komanso anthu omwe ali ndi masamba omwe amafalitsa nthawi zonse.

● Mtengo wa adsl ungasinthe kwambiri chifukwa opereka ma intaneti ali ndi ntchito zokwanira nambala inayake, koma kuchuluka komwe kukuwonjezekera kukuwakakamiza kukulitsa ntchito zawo ndipo izi zidzawononga ndalama zambiri, chifukwa chake mtengo umatha kusintha ndi ichi ndichinthu chomwe opereka chithandizo samafotokozera makasitomala

Ndipo muli ndi thanzi labwino komanso chitetezo cha otsatira athu okondedwa
