I-Megabytes Iifowuni ze-Intanethi Zidla
Umjikelezo kwi-calculators yokusetyenziswa kwedatha kwi-Intanethi ibonisa ukuba abaninzi, ukuba bonke abakho, abafaki ukusetyenziswa kwedatha ye-VoIP ekuqwalaselweni kwabo bachitha idatha kwisicwangciso sedatha . Ukusetyenziswa kwedatha yeVoIP ingumlinganiselo wama-kilobytes kunye ne-megabytes oyisebenzisayo kwisicwangciso sakho sedatha yokunxibelelana ngezwi. Abantu abaninzi abayisebenzisi isicwangciso sabo sedatha yeselula sokunxibelelana ngelizwi , kwaye balahlekelwa kakhulu. Ukwenza ikhwelo yefowuni kwifowuni yakho yeselula ngaphezu kwesicwangciso sakho sedatha ikuvumela ukuba ulondoloze imali eninzi kunxibelelwano; yibone ukuba zezizathu zokuba abantu basebenzisa iVoIP . Ngaphandle koko, ukusebenzisa imizuzu yakho yedatha ukwenza iifowuni zifanelekile ngakumbi kunokuba ukhangele ividiyo okanye ulandele i-MP3, umzekelo. Ngoko, ukuba i-VoIP yinto ekusebenziseni kwedatha yakho yeselula , nantsi indlela uqikelela ngayo umda wokuhamba umda owufunayo kwiifowuni zenyanga. Ungongeza ke loo xabiso kwi- calculator yakho yokusebenzisa idatha .
Zingaphi Amaminithi?
Yenza uqikelelo lwemali yemizuzu yokubiza oyifunayo. Ziquka zombini iifowuni eziphumayo nezingenayo. Oku akuwona msebenzi olula. Enye indlela yokuyifumana ngayo kukuba uthathe inyanga yesampula ngokubhala phantsi iifowuni ozenzileyo kwaye zenziwe kunye nexesha. Ukuba unayo i- smartphone , uyagcinwa ekusebenziseni ipeni kunye nephepha. Ngaphezu koko, unokukwazi ukuba neefowuni ezenza umsebenzi kuwe kwimvelaphi.
Uya kufuna ukuhlukanisa phakathi kweentlobo zeefowuni ozenzayo. Kukho iifowuni ezifuna ukudlula kwi-GSM. Uza kukhetha i- VoIP kwiifowuni ezifana neefowuni zamazwe ngamazwe , oonxibelelwano abasebenzisa inkonzo efanayo ye-VoIP njengawe (ezi fowuni zikhululekile) okanye iifowuni ezikhululekile kwindawo yangaphandle ngeenkonzo ezithile ze-VoIP (umzekelo, khangela i- Gmail ukubiza ).
Inani lee-Bytes ligqityiweyo
Ukukwazi ngokuthe ngqo ukuba zingaphi iindidi intetho yezwi idla, kufuneka ukwazi ukuba iyiphi i-codec isevisi yakho ye- VoIP . I-codec iyinjini yokunyanzelisa iguqula igama lakho (analog) kwi data yedijithali, isusa ixesha elithe cwaka (elenza isiqingatha kuzo zonke iingxoxo), kwaye wenze ezinye izinto ukunika umthwalo wedatha njengokukhanya. Funda ngaphezulu kwiikhowudi zekhowudi.
Nazi ixabiso elikufutshane lokusetyenziswa kwedatha yeekodec eziqhelekileyo ezisetyenziselwa iVoIP:
G.711 - 87Kbps
G.729 - 32 Kbps
G.723.1 - 22 Kbps
G.723.1 - 21 Kbps
G.726 - 55 Kbps
G.726 - 47 Kbps
G.728 - 32 Kbps
Ezi zithethe ziya kukunika umba wokubala. Umzekelo, ngomzuzu omnye wokuthetha kunye ne-G.729 codec, siya kwenza oku kulandelayo:
I-G.729 ithatha iikhilobithi ezingama-32 ngesibini,
e-1920 kilobits (60 x 32) ngomzuzu omnye,
okuyi-240 kilobytes (KB) ngomzuzu (1 byte yi-8 bits)
Ngoku ke kuphela idatha ephuma. Idatha ebangeleyo (ekwabalulekayo) ithatha umthwalo ofanayo, ngoko sinokuphindaphinda kabini i-480 KB.
Ekugqibeleni, sinokujikeleza ixabiso ukuya kwi-0.5 MB nganye ngomzuzu wencoko.
I-codec ye-G.729 yenye yeefowuni ezenziwayo ezilungileyo kakhulu kunye neenkonzo ezininzi ezilungileyo zeVoIP zisebenzisa.
Kufuneka uqaphele ukuba kukho iiparameter ezininzi, ezona zendalo ngokwemvelo, ezichaphazela ixabiso elingentla. Phakathi kwazo ubukhulu (ukuhlawula umvuzo) kweepakethi zegama, iisithuba apho zihanjiswe khona kunye nenani leepakethi ezithunyelwe kwisibini esinye (ubukhulu). Kwabaninzi bethu, into esiyifunayo iqikelele ukuqikelela. Ngoko, sinokukuphelisa ngokulula ukuchaneka. Kwakhona, asikwazi ukuba yeyiphi i-codec esetyenziswayo. Ngokomntu, ndithatha ixabiso eliqhelekileyo le-50 kbps kunoma iyiphi i-codec. Oku kunika (emva kokubala nokulinganisa) 0.75 MB ngomzuzu wencoko.
Ngoko, ukuba uceba iyure yendibano, kuya kuba ngu-45 MB.
