Ukuqonda izici ezithinta ukusebenza kwenethiwekhi yekhompyutha
Kanye nokusebenza okuyisisekelo nokuthembeka, ukusebenza kwenethiwekhi yekhompiyutha kunquma ukuthi kuyasiza kangakanani. Ijubane lenethiwekhi liqukethe inhlanganisela yezici ezihlobene.
Kuyini Isivinini Senethiwekhi?
Abasebenzisi ngokusobala bafuna amanethiwekhi abo ukuba asebenze ngokushesha kuzo zonke izimo. Kwezinye izimo, ukulibaziseka kwenethiwekhi kungadlulela kuphela amamillisecond ambalwa futhi kube nomthelela ongathandeki kulokho okwenziwa umsebenzisi. Kwezinye izimo, ukubambezeleka kwenethiwekhi kungabangela ukuwohloka okukhulu komsebenzisi. Izimo ezejwayelekile ezibucayi kakhulu ezindabeni zejubane lenethiwekhi zifaka phakathi
- isikhathi sokwakha uxhumano olusha
- isikhathi sokulayisha ikhasi lewebhu
- isikhathi sokulanda uhlelo lokusebenza, isiqeshana sesistimu yokusebenza, noma amanye amafayela
- ikhono lokusakaza okuqukethwe kwevidiyo isikhathi eside ngaphandle kwama-glitches
Indima ye-bandwidth ekusebenzeni kwenethiwekhi
I-Bandwidth iyisici esibalulekile ekunqumeni isivinini senethiwekhi yekhompyutha. Cishe wonke umuntu uyazi ukulinganiswa komkhawulokudonsa wezintambo zabo zenethiwekhi kanye nensizakalo yabo ye-Intanethi, izinombolo ezivelele ngokuphawulekayo kwizikhangiso zomkhiqizo
Ububanzi bomthamo ekuxhumaneni kwekhompyutha kubhekisela kwisilinganiso sedatha esekelwe uxhumano lwenethiwekhi noma isikhombikubona. Imelela umthamo jikelele wokuxhumana. Uma kukhona amandla amaningi, cishe amathuba okusebenza kangcono azophumela.
Ukuhamba komkhawulokudonsa kubhekisela kokubili izilinganiso zokulinganisa kanye nokufaka kwangempela, futhi kubalulekile ukuhlukanisa phakathi kokubili. Isibonelo, uxhumano olujwayelekile lwe- Wi-Fi lwe- 802.11g lunika ama - 54 Mbps we-bandwidth elinganisiwe kodwa ngomkhuba ufeza kuphela 50% noma ngaphansi kwale nombolo ekufakweni kwangempela. Amanethiwekhi wendabuko e- Ethernet asekela ngokuyinhloko ama-100 Mbps noma angu-1000 Mbps we-bandwidth esiphezulu, kodwa lesi sikhundla esiphezulu asikwazi ukufinyeleleka ngokufanele. Amanethiwekhi weselula (mobile) ngokuvamile awasho ukuthi kunoma yikuphi ukulinganiswa komkhawulokudonsa okwehlukile kodwa isimiso esifanayo sisasebenza. Izingxube zokuxhumana kwi-hardware yekhompuyutha, izivumelwano zenethiwekhi , nezinhlelo zokusebenza zenza umehluko phakathi kwe-bandwidth ye-theoretical kanye nokufaka kwangempela.
Ihlola ukuhamba komkhawulo wenethiwekhi
Umkhawulokudonsa ungumthamo wedatha odlula uxhumano lwenethiwekhi ngokuhamba kwesikhathi njengoba kulinganiswa ngamabikithi ngomzuzwana (i-bps) .Amathuluzi angabonakali akhona kubaphathi ukukala ukuhamba komkhawulo wokuxhumana kwenethiwekhi. Ku- LAN (amanethiwekhi wendawo) , la mathuluzi afaka netperf ne- ttcp . E-intanethi, kunezinhlelo eziningi zokuhlola zokuhamba kwe-bandewidth kanye nejubane ezikhona, ezitholakala kakhulu ekusetshenzisweni kwe-inthanethi mahhala.
Ngisho nalawa mathuluzi onawo, ukusetshenziswa komkhawulokudonsa kunzima ukulinganisa ngokunembile njengoba kuhluka ngokuhamba kwesikhathi kuye ngokucushwa kwe-hardware kanye nezici zezinhlelo zokusebenza zesofthiwe kubandakanya ukuthi zisetshenziswa kanjani.
Mayelana Nokusheshiswa Kokudlulisa
Igama elithi bandwidth eliphakeme ngezinye izikhathi lisetshenziselwa ukuhlukanisa ukuxhumeka okusheshayo kwe- intanethi ekuxhumaneni kwendabuko noma ngesivinini senethiwekhi yeselula. Izincazelo ze-bandwidth "eziphezulu" ezibhekiselele "eziphansi" ezihlukahlukene futhi ziye zabuyekezwa phezu kweminyaka njengoba ubuchwepheshe benethiwekhi buphuthukisiwe. Ngo-2015, i-Federal Federal Commission (i-FCC) yase-United States ivuselele incazelo yabo yokusakaza okubanzi ukuba yilawo maxhumo alinganiswe okungenani ama-25 Mbps okulandwayo futhi okungenani ama-3 Mbps wokulayisha. Lezi zinombolo kuboniswe ukwanda okukhulu kusuka ezincane ezingaphansi kuka-4 Mbps ku-FCC no-1 Mbps phansi. (Eminyakeni eminingi edlule, i-FCC ibeke ubuncane bayo ku-0.3 Mbps).
Ububanzi bomkhawulo akuyona kuphela into ebangela isivinini esikubonayo senethiwekhi. Into eyaziwa encane yokusebenza kwenethiwekhi - i- latency - nayo idlala indima ebalulekile.
