Bandiwifi mwayi maukonde

Ndi kuchuluka ambiri Intaneti kompyuta , mawu akuti "bandiwifi" zinadziwika kwa aliyense. Ndipo ngati chidwi kale anali mwangwiro ongolankhula, koma tsopano zonse ndi osiyana. Kumvetsa chimene chinapangitsa mawu "bandiwifi maukonde" limakupatsani kusankha zabwino kwambiri athandizi (hereinafter amatanthauza maukonde m'dera ndi Internet), komanso njira mulingo woyenera kukhazikitsa ntchito maukonde.

Tisanafotokoze wofufuza chiphunzitso, tiyeni tione zinthu zopindulitsa, yomwe, tsoka, nthawi zambiri akukumana Intaneti tikukhala mu m'mayiko amene kale anali Soviet Union. Monga mukudziwa, pamene inu kulumikiza ndi wosamalira zopezera mwayi utumiki mapulani tariff zawo zimasonyeza liwiro ndi manambala oyambirira "mmwamba." Mwachitsanzo, "10 MB / s", "50 MB / s," etc.

Ndipotu mphamvu njira ndi malo zogwirizana. Tiyeni tione nkhani kuti panthawi ina nthawi maukonde WOPEREKA kutumikira zikugwirizana ndi wolembetsa. Monga ulamuliro, amatipatsa zonse adzapereke liwiro. Pofuna zolinga zachuma, WOPEREKA kampani akupitiriza kuti apeze olembetsa latsopano. Chifukwa, izo zakhala zinthu zachilengedwe, pamene nthawi yomweyo akuyambitsa kugwirizana kuti ambiri owerenga Intaneti. tariff chimodzi "50 MB", wina wachitatu ...

The zomveka zotsatira - mlingo dontho la onse ananena pansipa (kumbukirani ndi manambala oyambirira "mpaka"). Yambani kuyitana odandaula olembetsa, mavuto ofanana ndi kulankhulana ndi zina zotero. Poyankha, thandizo munanena kuti bandiwifi yochepa. Ndithudi, ichi ndi bwino kuti owerenga ambiri. About ndichiyani ndi chifukwa liwiro wagwa?

Mu 1920, ndi American kafukufuku Ralf Hartli zamagetsi ndi wasayansi Garri Nikvist, kuthetsa mavuto a mudziwe kutengerapo mu Telegraph, kukonza mbali yaikulu ya ndondomeko kusintha deta. Mmodzi wa chopambana - ndi ubale pafupipafupi HIV ndi nthawi. Choncho, Hartley anakonza lamulo malinga ndi zomwe chiwerengero cha opatsirana deta njila kwa pafupipafupi kufala ntchito ndi ntchito nthawi. Mu 1927 godu Nyqvist Mukalongosola kuti opatsirana kuchuluka mtengo yochepa kawiri pafupipafupi ntchito (kutanthauza HIV popanda imfa deta pa nthawi wagawo). Only mwachidule zotsatira za ntchito yawo, kuyesa chiphunzitso mu 1940, Shannon deta ndi lingaliro la "kugwirizana bandiwifi."

Pafupipafupi osiyanasiyana ntchito kufala kwa mudziwe njira amatchedwa "bandiwifi". Kuyambira Lingaliro Lovomerezeka Shannon chikusonyeza kuti kukhala ndi liwiro pazipita zotheka ndi kuwonjezera mphamvu chizindikiro bandiwifi, kuchepetsa onyenga phokoso. Kuchuluka liwiro ndi kusinthasintha mawu mbendera ndi zovuta, popeza pamene kuwonjezeka zimachitika amachepetsa chiwerengero pa nthawi wagawo, ndi pa compaction ndi kuchepetsa nthawi ya kumaliseche limodzi kumawonjezera chiwerengero cha kutayika wochititsa lapansi. Nthawi zambiri, adzionere m'lifupi kuchita masamu mfundo kuganizira pafupipafupi anasankha.

Tikumbukenso kuti mphamvu njira zikuphatikizapo osati chizindikiro anakhumba komanso phokoso. Izi zikhoza kukhala mu atomu kuwasokoneza, katundu wa wochititsa ndi ndondomeko chinyezimiro gauss ndi zina zotero. The wolandila amalandira otaya zonse za chizindikiro ndi Zosefera kunja mbali ankafuna.

Tikaonanso chitsanzo: pamene ambiri olembetsa mofulumira anafika malire a deta okwana mtsinje kwa pafupipafupi kufala ntchito ndi athandizi (mzere kuwala, kugwirizana wailesi, mkuwa waya). Pofuna kuthetsa vutoli, kuonjezera mphamvu chizindikiro kusintha kufala pafupipafupi ndi chilengedwe (zamtengo wapatali monga kumafuna wamakono wa zida), kapena kuti asagwiritse otaya kafukufuku wina wolembetsa imene ikuchitika.
