Yikuphi i-Bluetooth, Okukwenzayo, nokuthi Isebenza Kanjani
I-Bluetooth yikhokhnoloji yokuxhumana engaxhunyiwe engenaxhunyiwe engenazintambo evumela ukuthi amadivaysi afana namafoni, amakhompiyutha, nezinsimbi zokudlulisela idatha noma izwi ngaphandle kwentambo. Inhloso ye-Bluetooth ukufaka esikhundleni sezintambo ezivame ukuxhuma amadivaysi, ngenkathi zigcina ukuxhumana phakathi kwabo kuphephile.
Igama elithi "Bluetooth" lithathwe enkosini yaseDenmark yekhulu le-10 okuthiwa iHarald Bluetooth, okuthiwa ukuhlanganisa izingxenye ezingezansi eziphikisanayo. Njengama-nameake ayo, ubuchwepheshe be-Bluetooth buhlanganisa ndawonye ububanzi obubanzi bamadivaysi ezimboni eziningi ezahlukene ngokusebenzisa ukulinganisa okujwayelekile.
Ubuchwepheshe be-Bluetooth
Ethuthukisiwe ngo-1994, i-Bluetooth yayihloselwe ukufakwa esikhundleni senethiwekhi yezintambo. Isebenzisa imvamisa efanayo ye-2.4GHz njengamanye ubuchwepheshe obungenawaya ekhaya noma ehhovisi, njengamafoni angenantambo kanye nama-WiFi routers. Idala inethiwekhi engenazintambo engamamitha angu-10 (33) engama-wire, ebizwa ngokuthi inethiwekhi yendawo yomuntu siqu (i-PAN) noma i-piconet, engaxhuma phakathi kwamadivayisi amabili nesishiyagalombili. Le nethiwekhi ye-intanethi efushane ikuvumela ukuba uthumele ikhasi kuphrinta yakho kwelinye igumbi, isibonelo, ngaphandle kokusebenzisa ikhebula elingabonakali.
I-Bluetooth isebenzisa amandla angaphansi futhi ibiza kancane ukuqaliswa kune-Wi-Fi. Amandla ayo aphansi nawo enza kube lula ukuhlukunyezwa namanye amadivaysi angenawaya efonini elifanayo le-2.4GHz.
Ibanga le-Bluetooth kanye nokusheshisa okuhambayo ngokuvamile kuncipha kune-Wi-Fi (inethiwekhi yendawo engenantambo ongayithola ekhaya lakho). I-Bluetooth v3.0 + i-Bluetooth-speed Bluetooth-amadivaysi e-HS-Bluetooth anganikela ku-24 Mbps yedatha, esheshayo kunesilinganiso esingu- 802.11b se-WiFi , kodwa ihamba kancane kunamazinga angenawaya noma angenawaya-wire. Njengoba ubuchwepheshe buguqukile, noma kunjalo, isivinini se-Bluetooth senyukile.
Ukuchazwa kwe-Bluetooth 4.0 kwamukelwa ngokomthetho ngoJulayi 6, 2010. Izici ze-Bluetooth version 4.0 zihlanganisa amandla aphansi okusetshenziswa, izindleko eziphansi, ukusebenzisana kwamanethiwekhi, kanye nokuphakama okuthuthukisiwe.
Isici esibonisa ukuthuthukiswa kwi-Bluetooth 4.0 spec yizidingo zayo eziphansi; Amadivaysi esebenzayo nge-Bluetooth v4.0 ahlelwe ukusebenza kwebhethri ephansi futhi angagijima ngamabhethri amancane eseceleni-cell, avule amathuba amasha kwezobuchwepheshe obungenawaya. Esikhundleni sokwesaba ukuthi ukushiya i-Bluetooth kuzokhipha ibhetri yefoni yakho, isibonelo, ungashiya ifoni ye-Bluetooth v4.0 ixhunywe sonke isikhathi kwezinye izesekeli zakho ze-Bluetooth.
Ukuxhuma Nge-Bluetooth
Amadivayisi amaningi eselula ane-radios e-Bluetooth afakwe kuwo. Ama-PC namanye amadivaysi angenawo ama-radios akhakhiwe angaba ne-Bluetooth ngokunika amandla i-Bluetooth dongle , isibonelo.
Inqubo yokuxhuma amadivaysi amabili e-Bluetooth ibizwa ngokuthi "ukubambisana." Ngokuvamile, amadivaysi asakaza izigcawu zabo, futhi umsebenzisi ukhetha idivayisi ye-Bluetooth abafuna ukuyixhuma uma igama layo noma i-ID ivela kudivayisi yabo. Njengoba amadivaysi anikwe amandla e-Bluetooth akhula, kubalulekile ukuthi wazi ukuthi iyiphi idivayisi futhi uxhumeke kuphi, ngakho-ke kungenzeka kube khona ikhodi yokungena okusiza ukuqinisekisa ukuthi uxhumeka kudivayisi efanele.
Le nqubo yokubambisana ingahluka ngokuya kumadivayisi abandakanyekayo. Isibonelo, ukuxhuma idivaysi ye-Bluetooth ku-iPad yakho kungabandakanya izinyathelo ezahlukene ezivela kulabo ukubhangqa idivayisi ye-Bluetooth emotweni yakho .
Ukulinganiselwa kwe-Bluetooth
Kunamaphuzu athile ku-Bluetooth. Okokuqala ukuthi kungaba ukukhipha amandla ebhetri kumadivayisi angenantambo angenawaya njengama-Smartphones, nakuba njengoba ubuchwepheshe (nobuchwepheshe bebhethri) buye buphuthumayo, le nkinga ayibalulekile kakhulu kunalokho eyayikhona.
Futhi, ububanzi bulinganiselwe, ngokuvamile bukhula cishe ngamamitha angu-30, futhi njengalabo bonke ubuchwepheshe obungenazintambo, izithiyo ezifana nezindonga, phansi, noma ukufakwa kunganciphisa lokhu kuhla.
Inqubo yokubambisana ingase ibe nzima, ngokuvamile ngokuya ngamadivaysi abandakanyekayo, abakhiqizi, nezinye izici ukuthi konke kungabangela ukukhungatheka uma uzama ukuxhuma.
Ukuphepha Kanjani I-Bluetooth?
I-Bluetooth ibhekwa ubuchwepheshe obungenawaya obuphephile uma isetshenziswa ngokuqapha. Ukuxhumeka kubhalwe ngekhodi, kuvimbela ukususa okulula okuvela kwamanye amadivayisi aseduze. Amadivaysi e-Bluetooth abuye aguqule amafrikhoni omsakazo kaningi ngenkathi ehlangene, okuvimbela ukuhlasela okulula.
Amadivayisi futhi anikeza izilungiselelo ezihlukahlukene ezivumela umsebenzisi ukuthi anciphise uxhumano lwe-Bluetooth. Ukuphepha kwezinga ledivayisi "ukuthembela" idivaysi ye-Bluetooth kuvumela ukuxhuma kuphela kuleyo divayisi ethize. Ngezilungiselelo zokuphepha ezingeni lesevisi, ungakwazi futhi ukuvimbela izinhlobo zemisebenzi idivayisi yakho evunyelwe ukuba ihlanganyele ngenkathi uxhumano lwe-Bluetooth.
Njenganoma yibuphi ubuchwepheshe obungenazintambo, kunjalo, kukhona njalo ingozi yokuphepha ehilelekile. Abahlaseli baye bahlela ukuhlaselwa okunonya okusebenzisa inethiwekhi ye-Bluetooth. Isibonelo, i- "bluesnarfing" ibhekisela ku-hacker ukuthola ukufinyelela okugunyaziwe kolwazi kudivayisi ngokusebenzisa iBluetooth; "i-bluebugging" yilapho umhlaseli ethatha iselula yakho nayo yonke imisebenzi yayo.
Ngomuntu ojwayelekile, i-Bluetooth ayikho ingozi yokuvikeleka enkulu lapho isetshenziselwa ukuphepha engqondweni (isib. Ukuxhuma kumadivayisi angaziwa e-Bluetooth). Ukuze uvikeleke kakhulu, ngenkathi usesidlangalaleni futhi ungasebenzisi i-Bluetooth, ungawukhubaza ngokuphelele.
