Yiyiphi i-Bluetooth, into eyenzayo, nendlela esebenza ngayo
I-Bluetooth yinkcazo ye-intanethi ye- wireless ye-intanethi eyenza iifowuni ezinjengeifowuni, iikhomputha, kunye nemipheripherithi yokudlulisa idatha okanye ilizwi ngaphandle kwentambo emfutshane. Injongo yeBluetooth kukutshintsha iifowuni eziqhele ukuxhuma amadivaysi, ngelixa zigcina uxhulumaniso phakathi kwazo zikhuselekile.
Igama elithi "iBluetooth" lithathwe kwikosi yeDenmark yekhulu le-10 eyayibizwa ngokuthi nguHarald Bluetooth, owathethwa ukuba adibanise amaqela ahlukeneyo. Njengamagama ayo, iteknoloji yeBluetooth idibanisa uluhlu olubanzi lwezixhobo kumashishini amaninzi ahlukeneyo ngokubambisana komgangatho wokunxibelelana.
Ubuchwepheshe beBluetooth
Ukuphuhliswa ngo-1994, i-Bluetooth yayijoliswe ekutshintsheni i-wireless cables. Isebenzisa inqanaba elifanayo le-2.4GHz njengamanye ubuchwepheshe obungenazintambo ekhaya okanye kwiofisi, njengeefowuni ezingenazintambo kunye ne-WiFi routers. Yakha inethiwekhi ye-wireless radius eyi-10-meter (33-foot) engama-wireless network, ebizwa ngokuba yintanethi yendawo yomntu (PAN) okanye i-piconet, inokudibanisa phakathi kwezixhobo ezimbini kunye nesibhozo. Olu hlobo lwenethiwekhi olufutshane luvumela ukuba uthumele iphepha kumshicileli wakho kwelinye igumbi, umzekelo, ngaphandle kokuba usebenzise ikhebula elingabonakaliyo.
I-Bluetooth isebenzisa amandla angaphantsi kunye neendleko ezingaphantsi kokuphumeza kune-Wi-Fi. Amandla ayo angaphantsi awenza ukuba angabi ncipheko ekubandezeleka okanye ekuphazamiseni ezinye iifowuni ezingenazintambo kwi-band ye-2.4GHz yomsakazo.
Uluhlu lweBluetooth kunye nesantya sokusasazeka ngokuqhelekileyo kuncinci kune-Wi-Fi (inethiwekhi yendawo engenazintambo onokuyenza ekhaya lakho). I-Bluetooth v3.0 + HS-i-Bluetooth i-speed-speed-devices iyakwazi ukuhambisa kwi-24 Mbps yedata, ekhawuleza kunomgangatho we-WiFi wama-802.11b , kodwa ihamba ngokukhawuleza kunemigangatho engena-wire okanye i-wireless-g. Njengoko iteknoloji iguqukile, kunjalo, ukuhamba kweBluetooth kuye kwanda.
Inkcazelo yeBluetooth 4.0 yamukelwa ngokusemthethweni ngoJulayi 6, 2010. Iinkalo zeBluetooth version 4.0 ziquka ukusetyenziswa kwamandla aphantsi, iindleko eziphantsi, ukusebenzisana kwamanye amazwe kunye nolwaphulo oluphuculweyo.
Uphawu oluphawulekayo lokuphuculwa kwiBluetooth 4.0 isisiseko samandla aphantsi; Izixhobo esebenzisa i-Bluetooth v4.0 zilungiselelwe ukusebenza kwebhetri ephantsi kwaye ziyakwazi ukugijima kwiibhetri ezincinci zeseli, ukuvula amathuba amatsha ngobuchwepheshe be-wireless. Esikhundleni sokwesaba ukuba ukushiya iBluetooth kuyo kutshaba ibhetri yefowuni yakho, umzekelo, unokushiya ifowuni ye-Bluetooth v4.0 ixhunyaniswe onke amaxesha nakwezinye izixhobo zeBluetooth.
Ukuxhuma neBluetooth
Zininzi izixhobo eziphathekayo zinama-radios e-Bluetooth afakwe kuwo. Ii-PC kunye nezinye iifowuni ezingenayo i-radios ezakhiweyo zingabonakalisa i-Bluetooth ngokungongeza i- dongle , umzekelo.
Inkqubo yokudibanisa iifowuni zeBluetooth ibizwa ngokuba "ukudibanisa." Ngokuqhelekileyo, iifayili zisasaza izibhengezo zabo komnye nomnye, kwaye umsebenzisi ukhetha idivaysi yeBluetooth afuna ukuyixhuma xa igama layo okanye i-ID ivela kwisixhobo sakho. Njengoko izixhobo ezisebenzayo zeBluetooth ziyancipha, kubalulekile ukuba uyazi ukuba nini kunye naluphi idivaysi odibanisayo, ngoko kukho ikhowudi yokungena ekunceda ukuba udibanise kwisixhobo esifanelekileyo.
Le nkqubo yokubambisana ingahlukahluka kuxhomekeke kwizixhobo ezibandakanyekayo. Umzekelo, ukudibanisa idivaysi ye-Bluetooth kwi-iPad yakho inokubandakanya amanyathelo ahlukeneyo kulabo ukudibanisa idivayisi yeBluetooth kwimoto yakho .
Iimpawu zeBluetooth
Kukho ukuhla kwe-Bluetooth. Eyokuqala kukuba ingaba ngumbane kwibhetri yamashishini angenazintambo ezingenazintambo ezifana nee-smartphone, nangona njengokuba iteknoloji (kunye ne-teknoloji yebhetri) iphucule, le ngxaki ayiyona nto ibaluleke kunokuba yayisetyenziswa.
Kwakhona, uluhlu aluphelelanga, ngokuqhelekileyo lwandisa malunga neenyawo ezingama-30, kwaye njengokuba kukho konke ubuchwepheshe be-wireless, izithintelo ezifana neendonga, phantsi, okanye iifowuni zinokunciphisa le ndlela.
Inkqubo yokubambisana ingaba nzima, ngokuthe rhoqo kuxhomekeke kwizixhobo ezibandakanyekayo, abakhiqizi kunye nezinye izinto ezibangelwa ukukhungatheka xa uzama ukuxhuma.
Ikhuselekile Njani i-Bluetooth?
I-Bluetooth ithathwa njengeteknoloji engenazintambo ezingenazintambo xa isetyenziswe ngokuqapha. Uxhumo lufakwe ngefayile, lukhusela ukukhupha okungaqhelekanga kwezinye iifowuni eziseduze. Iifowuni zeBluetooth zitshintsha iifom ye-radio ngokuphindaphindiweyo xa zibambene, ezithintela ukuhlasela okulula.
Amadivaysi anikezela ngeendlela ezahlukeneyo ezivumela umsebenzisi ukuba anciphise uxhulumaniso lweBluetooth. Ukukhusela kwinqanaba lekhompyutha "lokuthembela" isixhobo seBluetooth sinqanda ukudibanisa kuphela kweso sixhobo esithile. Ngezicwangciso zokhuseleko lwezinga lokuncedisa, unako ukukhawulela iintlobo zemisebenzi yakho ifowuni ivumelekile ukuba ihlanganyele ngexesha loxhumo lweBluetooth.
Njengalo naluphi na iteknoloji engenazintambo, kunjalo, kukho nengozi yokhuseleko olubandakanyekayo. Hackers baye baceba ezihlukahlukene ukuhlaselwa ezinobungozi ezisebenzisa inethiwekhi Bluetooth. Ngokomzekelo, "bluesnarfing" ibhekisela kwi-hacker ekufumaneni ukufumana imvume egunyazisiweyo kwisixhobo ngeBluetooth; "i-bluebugging" xa umhlaseli ethatha umnxeba wakho kunye nayo yonke imisebenzi yayo.
Ngomntu oqhelekileyo, i-Bluetooth ayifaki ingozi enkulu yokhuseleko xa isetyenziselwa ukhuseleko engqondweni (umz., Ungaxhumeki kwii-Bluetooth ezingaziwa). Ukuba ukhuseleko oluphezulu, ngelixa uluntu kwaye ungasebenzisi i-Bluetooth, unokukhubaza ngokupheleleyo.
