Futhi Noma kunjalo Ungasebenziseka
Ukulinganisa ijubane lenethiwekhi yekhompiyutha kungaba nzima, kodwa ekugcineni okubaluleke kakhulu kubantu abaningi ukuthi uxhumano luphendula kanjani uma uzama ukwenza umsebenzi othile. Ukuthi kushesha kangakanani noma kunciphise inethiwekhi kudinga ukuthi kuxhomeke endleleni oyisebenzisa ngayo. Ngokuvamile, njengoba amadivaysi amaningi nabantu bahlanganyela inethiwekhi, ukusebenza kwayo kangcono (kulinganiswa ngokwemibandela ye- bandwidth ne- latency ) kumele kube ukusekela umthwalo jikelele.
Izinga lokusesha ngewebhu
Ukusesha okuyisisekelo kweWebhu kungenziwa kunoma yiliphi ijubane lokuxhuma , kufaka phakathi i -intanethi ye-intanethi ye-dial-up noma izixhumanisi zefoni. Isikhathi esidingekayo kumthwalo wekhasi leWeb ukwanda ngokuphawulekayo ekuxhumaneni okuphansi kwejubane, noma kunjalo. Ukuxhumeka kwe- intanethi ye-Broadband ye-512 Kbps noma ukusekelwa okuphezulu kwe-web yokusekela nge-Inthanethi , nakuba ukuxhumana okusheshayo okusheshayo kusiza ngamakhasi anevidiyo nezinye okuqukethwe okucebile.
Ngaphandle komkhawulokudonsa wenethiwekhi, ukusakazwa kweWebhu kubuye kuzwele ekufinyeleleni kwenethiwekhi. Ukusakazwa kweWeb phezu kokuxhumeka kwe-intanethi ye-intanethi , isibonelo, kuthatha isikhathi eside kunezinsizakalo ze-intanethi ze-intanethi ezisezingeni eliphezulu ezihlinzeka nge-bandwidth efanayo, ngenxa ye- latency ephakeme ye-satellite.
I-imeyili ne-IM Isikhathi
Ukuthumela umbhalo phezu kwamanethiwekhi wekhompuyutha kudinga umkhawulokudonsa obuncane. Ngisho nokuxhumeka kwe-intanethi, okusheshayo kokudayela kwe-intanethi kusekela ngokwanele imilayezo esheshayo kanye ne-imeyili esekelwe kuwebhusayithi. Noma kunjalo, okunamathiselwe okukhulu okuthunyelwe nge-imeyili noma i-IM ukudluliswa kancane kancane ngokuxhumana okuphansi kwejubane. Okunamathiselwe okukodwa kwe-megabyte (MB) okuthunyelwe ngaphezulu kokudayela kungathatha amaminithi angu-10 noma ngaphezulu ukudlulisa phakathi kokuxhumeka, kuyilapho okunamathiselwe okufanayo kungathunyelwa phezu kokuxhumana okuhle kwe-broadband kumasekhondi ambalwa nje.
Ithelevishini kanye Nemiphumela Yokusakaza Yomculo
Ukusakaza kwevidiyo kusebentisa umkhawulokudonsa wenethiwekhi ngaphezulu noma ngaphasi ngokususelwa kwisinqumo nokukala kwesilinganiso sokuqukethwe okubukwayo kanye nobuchwepheshe be- codec esetshenziswa ukucindezela nokucacisa ozimele ngabanye. Incazelo ejwayelekile yethelevishini, isibonelo, idinga u-3.5 Mbps ngokwesilinganiso, ngenkathi ukusakazwa kwekhwalithi ye-DVD kudinga kufika ku-9.8 Mbps. I-video ye-high-definition ividiyo ithelevishini ngokuvamile idinga i-10-15 Mbps nevidiyo ye -Blu-ray kufika ku-40 Mbps. Isilinganiso esincane sangempela sevidiyo enikeziwe sishintsha phezulu nangaphezulu ngokuhamba kwesikhathi esekelwe kokuqukethwe; Ama-movie anesithombe esiyinkimbinkimbi nokunyakaza okukhulu kudinga umkhawulokudonsa obuningi.
I-Speech Conferencing Speeds
Ukuvinjelwa kwenethiwekhi okudingekayo ye-video conferencing kufana nethelevishini, ngaphandle kokuthi imikhiqizo yezinkomfa zevidiyo inikeza ukuxazululwa okuphansi nezinketho zekhwalithi ezinganciphisa kakhulu izidingo zomkhawulokudonsa. Imikhiqizo yokuxhumana yomuntu siqu njenge- Apple iChat , isibonelo, idinga i-900 Kbps (0.9 Mbps) kumhlangano womuntu womuntu amabili. Imikhiqizo yezinkampani zokuxhumana zevidiyo isebenzisa ukuphakama komgwaqo okuningi kuze kube yizidingo ezijwayelekile ze-TV yokuchaza (3-4 Mbps), kanye nezinhlelo ezintathu-nezindlela ezine zandisa futhi izidingo zejubane ngokuqhubekayo.
I-Inthanethi Yomsakazo (Ukusakaza Audio) Ngokushesha
Uma kuqhathaniswa nevidiyo, ukusakaza kwe-audio kudinga umkhawulokudonsa omkhulu wenethiwekhi. Umsakazo we-Intanethi ephakeme kakhulu uvame ukusakazwa ngo-128 Kbps, kuyilapho i-podcast noma ukudlala umculo wevidyo kudinga okungaphezu kwama-320 Kbps.
Ukuhamba kwegeyimu ku-intanethi
Amageyimu e-intanethi asebenzisa kakhulu ukuhlukahluka okungafani kwenethiwekhi ye-networkwidth kuye ngokuthi uhlobo lomdlalo ukuthi lwakhiwe kanjani. Amageyimu ane-motion esheshayo (njengabantu abaqala ukudubula kanye nezihloko zokugijima) bavame ukudinga ukuhamba komkhawulo omkhulu kunamamodeli kanye nemidlalo ye-Arcade esebenzisa ihluzo ezilula. Noma yikuphi ukuxhumeka kwenethiwekhi ye-broadband noma inethiwekhi yesikhashana kunikezwa umkhawulokudonsa okwanele wokudlala ku-intanethi.
Ukudlala ku-intanethi kudinga ukuxhumeka kwenethiwekhi ephansi-latency ngaphezu kokuhamba komkhawulokudonsa okwanele. Amageyimu e-interactive asebenza kwinethiwekhi eno-round-trip latency amakhulu kunama-millisecond angaba ngu-100 avame ukuhlushwa yi- lag ebonakalayo. Isamba esiqondile selagi esamukelekayo sincike ekuboneni kwabadlali ngabanye kanye nohlobo lomdlalo. Abadubuli bokuqala, isibonelo, ngokuvamile badinga ukuvinjwa kwenethiwekhi ephansi kakhulu.
