Kanti Sebenokusetyenziswa
Ukulinganisa isantya somnatha wekhompyutha kunokuba nzima, kodwa ekugqibeleni into ebalulekileyo kubantu abaninzi kukuba ukuxhamla ukuphendula kuthini xa uzama ukufeza umsebenzi othile. Kwenzeka ngokukhawuleza okanye ukukhawuleza inethiwekhi kufuneka kuxhomekeke kwindlela oyisebenzisa ngayo. Ngokubanzi, njengoko amacebo amaninzi kunye nabantu babelana nenethwekhi, ngcono ukusebenza kwayo (kulinganiswa ngokwemigca yendlela yokuhamba kunye ne- latency ) kufuneka kukuxhasa umthwalo jikelele.
Ukukhawuleza kweWebhu
Ukukhwela kwi-Web eSebenzi kunokwenziwa ngaphaya kwesantya soxhumano , kubandakanywa i -intanethi ye-intanethi okanye ifowuni. Ixesha elifunekayo kumthwalo wekhasi leWebhu landa kakhulu kwiinkcukacha ezisezantsi, nangona kunjalo. Ukuxhumeka kwe- intanethi ye-intanethi ye-512 Kbps okanye ukusekwa kwe-Web kwesebe ephezulu, nangona ukuxhunywa okukhawulezayo kunceda ngamaphepha anevidiyo kunye nomxholo ocebileyo.
Ngaphandle kwendlela yomnatha wenethiwekhi, ukukhwela kwiWebhu kuyanqwenela ukuxhunywa kwintanethi. Ukukhwela kwiwebhu kwiinkcukacha ze-intanethi kwi-intanethi , umzekelo, kuthatha ixesha elide kunokuba iinkonzo ze-intanethi ze-intanethi zixhaswe nge-bandwidth efanayo, ngenxa ye- latency ephezulu ye-satellite.
I-imeyile kunye ne-IM Impendulo
Ukuthumela itekisi kumanethiwekhi ekhomputha kudinga ibhanwidth encinane. Nokuba unxibelelwano lwe-Intanethi oludala, oluxothayo lwe-intanethi luxhasana ngokwaneleyo ukuthumela imiyalezo esheshayo kunye ne-imeyile esekelwe kwiWebhu. Nangona kunjalo, izikhonkwane ezinkulu ezithunyelwe nge-imeyile okanye kwi-IM idluliselwe ngokukhawuleza phezu kokunxibelelana kwekhawulezileyo. Inamathiselo enye ye-megabyte (MB) ithunyelwe ngaphezulu kokudayela ingathatha imizuzu eyi-10 okanye ngaphezulu ukuze idlulisele kuyo yonxibelelwano, ngelixa unxibelelwano olufanayo lunokuthunyelwa kwikhonkco elungileyo lebhodi yebhanki ngemizuzwana embalwa nje.
Ithelevishini kunye neNkqubela yokuPhumela kweMidlalo
Imifudlana yeefayile isebenzisa ubuninzi bee-bandwidth zethungelwano ezingaphezulu okanye ngaphantsi ngokusekelwe kwisisombululo kunye nomlinganiselo wesreyimu somxholo ojongwa kunye nekhnoloji ye - codec esetyenziselwa ukunyanzelisa nokucwangcisa amafowuni ngamnye. Intsingiselo yomsindo we-TV, umzekelo, ifuna i-3.5 Mbps ngokuqhelekileyo, ngelixa i-DVD ye-movie quality ukusakaza idinga ukuya kwi-9.8 Mbps. I-video ephakamileyo yevidiyo ithelevishini idinga i-10-15 Mbps kunye nevidiyo ye -Blu-ray ukuya kuma-40 Mbps. Isantya esona sinani sevidiyo esinikiweyo sitshintshela phezulu nangaphezulu ngexesha elisekelwe kumxholo; Iifilimu ezineemifanekiso eziyinkimbinkimbi kunye nentshukumo enkulu idinga i-bandwidth engaphezulu.
Iintetho zeNgcaciso zeVidiyo
Isantya esinqununu senethiwekhi ye-conferencing yevidiyo ifana ne-TV, ngaphandle kokuba imveliso yeenkomfa zevidiyo inika isisombululo esincinci kunye neendlela eziphezulu ezinokunciphisa iimfuno zamanqwanqwa. Imveliso yokudibanisa yomntu njenge- Apple iChat , umzekelo, idinga i-900 Kbps (0.9 Mbps) kwiseshoni yevidiyo yomntu ezimbini. Iimveliso zenkampani yokudibanisa i-video zisebenzisa i-bandwidth ukuya kwii-standard definition yeemfuno zeTV (3-4 Mbps), kunye neeseshoni zendlela ezintathu kunye nezine ziyakwandisa iimfuno zesantya.
I-Intanethi ye-Intanethi (Ukukhuphela kweeVidiyo) Ixesha
Xa kuthelekiswa nevidiyo, ukusasazwa kwomsindo kudinga amanqaku amaninzi kunethiwekhi. I-intanethi ye-intanethi ye-high-quality iyasasazwa kwi-128 Kbps, ngelixa i-podcast okanye umdlalo wokudlala umculo ungadingi ngaphezu kwe-320 Kbps.
Ukukhawuleza kweMidlalo yeMidlalo
Iimidlalo ze-intanethi zisebenzisa iindidi ezihlukeneyo zetranswidth yenethiwekhi ngokuxhomekeke kwimiba yemidlalo kwindlela eyenziwe ngayo. Imidlalo ngokuhamba ngokukhawuleza (njengabantu abaqala ukudubula kunye nezihloko zokugijima) bathambekele ekufuneni umgama ongaphezu kwee-bandwidth kuneendlela zokumisa kunye nemidlalo ye-arcade esebenzisa imifanekiso elula. Naluphi na uxhumo lomnatha wamanethiwekhi okanye uxhumano lwenethiwekhi lweekhaya lunikezela ngokukhawuleza kwendlela yokudlala kwi-intanethi.
Ukudlala kwe-intanethi ngokubanzi kudinga uxhulumaniso lwe-latency low-intanethi kwongezwa kwinqanaba le- bandwidth elaneleyo. Imidlalo yokusebenzisana esebenza kwinethiwekhi kunye ne-latency-trip trip greater than about 100 milliseconds ithambekele kwi- lag ebonakalayo. Imali echanekileyo ye-lag eyamkelekileyo ixhomekeke kwingcamango yabadlali ngabanye kunye nohlobo lomdlalo. Umculi wokuqala, umzekelo, ngokubanzi ufuna i-latency network latencies.
