Ndi bandiwifi Kodi

Mawu akuti "bandiwifi" kawirikawiri anapereka pakompyuta Intaneti aya ntchito. Ichi ndi chimodzi mwa zizindikiro chifungulo cha madongosolo otero. Koyamba zingaoneke kuti munthu amene ntchito osalumikidwa ndi mizere kulankhulana, palibe kumvetsa zimene njira bandiwifi. Ndipotu, pang'ono cholakwika. Ambiri ndi nyumba makompyuta olumikizidwa kwa Internet. Ndipo aliyense amadziwa kuti nthawi zina ntchito ndi "World Lonse Web" popanda chifukwa chenicheni ndi liwiro. Chifukwa chimodzi n'chakuti pa nthawiyo kwambiri gulu WOPEREKA njira bandiwifi mwadzaza. Zotsatira - ndi slowdown bwino ndi wonongeka zotheka. Pamaso kumasulira lingaliro la "bandiwifi", ntchito chitsanzo, zimathandiza munthu kumvetsa zimene uli pangozi.

Tangoganizani msewu m'tauni yaing'ono ndi mu mzinda kuli anthu. Mbali yoyamba, ambiri a iwo lakonzedwa imodzi kapena ziwiri mitsinje ya galimoto, motero, m'lifupi yaing'ono. Koma m'mizinda ikuluikulu, ngakhale zinayi kanjira n'zosadabwitsa. Pa nthawi yomweyo chiwerengero cha magalimoto, kuyendetsa mtunda wofanana m'misewu awiri, n'chosiyana kwambiri. Izo zimatengera makhalidwe awiri - liwiro ndi chiwerengero cha zingwe. Mu chitsanzo ichi msewu - ndi kulankhulana njira, ndi makina ndi mfundo Akamva. Nayenso lililonse gulu - kugwirizana kulankhulana.

Mu mawu ena, bandiwifi kungotchula limasonyeza kuchuluka kwa deta akhoza opatsirana pa kulankhula njira pa nthawi unit. The apamwamba chizindikiro ichi, wabwino ntchito kudzera mwa pawiri.

Ngati mtengo kufala kwa zimaonekera onse (izo kumawonjezera ndi kuchepa kwa mbendera kufala ikuchedwa) Mawu akuti "bandiwifi" ndi pang'ono zovuta. Monga amadziwika kuti mbendera angathe popereka mauthenga mwa njira inayake, iye losandulizika. Umagwiritsidwa ntchito zamagetsi, kungakhale pafupipafupi, matalikidwe kapena wosanganiza kusinthasintha mawu. Koma wina mwa makhalidwe kufala kuti munthu ndi wochititsa chomwecho, nyemba angapo imafalikiranso imodzi pa mafurikwense osiyana (mu bandiwifi okwana monga kupotoza ndi malire zovomerezeka). Mbali imeneyi zimathandiza inu kuonjezera zokolola wonse wa kugwirizana popanda kusintha mwamsanga. Chitsanzo omveka a coexistence wa mafurikwense - kukambirana munthawi yomweyo anthu angapo ndi timbre osiyana. Ngakhale aliyense anena, koma aliwonse ali distinguishable ndithu.

N'chifukwa chiyani kugwira ntchito ndi zopezera zina liwiro zikuchitika? Onse chafotokozedwa kwambiri chabe:

- apamwamba a kachedwedwe, chindichepere liwiro. Aliyense ndimeyi kusokonezedwa chizindikiro (mapulogalamu kapena thupi) kuchepetsa liwiro;

- Nthawi zambiri mtsinje deta zikuphatikizapo Akamva zina zikugwira ntchito ntchito chibwereza - otchedwa "redundancy". Izi ndi zofunika kuonetsetsa ntchito imayenera mu zikhalidwe za kukhalapo kwa phokoso pa mzere;

- anafika malire thupi sing'anga kuchititsa pamene onse chovomerezeka ranges pafupipafupi kale ntchito ndi mbali yatsopano deta iwo anayikidwa mu ima pamzere kuti potumiza.

Kuti athetse mavuto awa wosamalira ntchito angapo mosiyana. Izi zikhoza kukhala virtualization wowonjezera "m'lifupi" koma womwe umapereka akuchedwa zina; kuwonjezera njira chifukwa cha "zoonjezera" kuchititsa TV ndi zina zotero.

Mawu akuti "baud" nthawi zina amagwiritsidwa ntchito mu njira yadigito. Ndipotu, zikutanthauza chiwerengero cha Akamva deta anasamutsidwa pa nthawi unit. Mu nthawi ya mizere pang'onopang'ono kulankhulana (oyimba-mmwamba) 1 bps limafanana 1 pang'ono pa 1 chachiwiri. Mtsogolo, ndi mlingo kukula, "baud" unatha konsekonse. Koma zimatanthauza 1, 2, 3 kapena zambiri Akamva pa chachiwiri, zofuna ndi umboni osiyana, kotero tsopano ntchito dongosolo losiyana, n'zomveka kuti aliyense.
