Chii chinonzi Bluetooth, Zvinoita, uye Zvazvinoita
Bluetooth ishungurudzo dzisina kufanira dzisingabviri kutauridzira inobvumira zvigadzirwa zvakadai sefoni, makombiyuta, uye mhirizhonga kudhinda dhidhi kana inzwi risina mhiri kwepfupi. Chinangwa cheBluetooth ndechokugadzirisa tambo dzinowanzobatanidza zvigadzirwa, asi dzichiri kuchengetedza hutano pakati pavo hwakachengeteka.
Izwi rokuti "bluetooth" rinotorwa kubva muzana remakore rechi10 rechiDanish chinonzi Harald Bluetooth, uyo akati aibatanidza kusawirirana, kurwisana nemapoka emagungano. Kufanana nemazita ayo, teknolojia yeBluetooth inounganidza huwandu hwakawanda hwezvigadzirwa zvemabhizimisi mazhinji akasiyana kuburikidza nekubatanidza hutano hwehutano.
Bluetooth Technology
Yakagadzirirwa muna 1994, Bluetooth yakagadziriswa senzvimbo dzisina kushandiswa dzesimbi. Iyo inoshandisa yakafanana 2.4GHz purogiramu yakafanana nedzimwe mimwe michina dzisina utsi mumusha kana kuti hofisi, yakadai sefoni dzisina kukwana uye mafaira eWiFi. Inoita mamita gumi nemasere (33-foot) radius network, inonzi nzvimbo yomunzvimbo (PAN) kana piconet, inogona kuwirirana pakati pemasere maviri uye masere. Iyi purogiramu-pfupi inotenderera inokutumira kutumira peji kune printer yako kune imwe nzvimbo, somuenzaniso, pasina kushaya unsightable cable.
Bluetooth inoshandisa simba shoma uye inodhura zvishomanana kushandisa kupfuura Wi-Fi. Simba raro rezasi rinoitawo kuti zvive nyore kudarika kutambura kana kukonzera kupindirana nemamwe magetsi asingasviki mune rimwe bhidhiyo re4GHz redhiyo.
Bhuku reBluetooth uye kutengesa kwemafambisi zvinowanzoperera kupfuura Wi-Fi (network wireless network iyo iwe ungave nayo mumba mako). Bluetooth v3.0 + HS-Bluetooth high-speed teknolojia-zvigadzirwa zvinokwanisa kupa kusvika 24 Mbps yedata, iyo inokurumidza kupfuura 802.11b WiFi yakawanda , asi inononoka kudarika wireless-a kana wireless-g mitemo. Sezvo teknolojia yakashanduka, zvakadaro, kubuda kweBluetooth kwawedzera.
Iyo Bluetooth 4.0 tsanangudzo yakagamuchirwa pamutemo musi waJuly 6, 2010. Bluetooth version 4.0 zvinosanganisira kushandiswa kwekushandisa simba, kudhura kwakaderera, kuwirirana kwevashandi, nekuwedzerwa mararamiro.
Chiratidzo chinowedzera kukurudzirwa kuBlue 4.0 spec ndiyo simba rayo rishoma; Zvishandiso zvinoshandisa Bluetooth v4.0 zvakagadziridzwa nebhateri shoma shoma uye dzinogona kumhanya kubva kune mari shoma-masero mabheteri, kuzarura mikana mitsva yekombiyuta isina uteresi. Panzvimbo pekutya kuti kusiya Bhutumoni kuchaita kuti bheneri yako yefoni ishandiswe, somuenzaniso, unogona kusiya bluetooth v4.0 foni yakabatana nguva dzose kune imwe yezvinhu zveBluetooth accessories.
Kubatana neBluetooth
Makombiyuta mazhinji efoni ane mabhidhiyo eBluetooth akaiswa mukati mavo. PC uye zvimwe zvigadzirwa zvisina kumbovakwa mumaihara zvinogona kuve neBluetooth-zvinobvira nekuwedzera Bluetooth dongle , somuenzaniso.
Nzira yekubatanidza mabhidhiyo maviri eBluetooth inonzi "pairing." Kazhinji, zvishandiso zvinoparidzira zvido zvavo kune mumwe nemumwe, uye musarudzo anosarudza bluetooth ravanoda kuti vabatanidze apo zita raro kana kuti ID yacho inowanikwa pane yavo. Sezvo ma-device-enabled-enabled anowedzera, inova yakakosha kuti uzive kuti ndipi uye kuti ndeipi chipikisi chako chaunosangana nacho, saka pangava nekodhi yekupinda iyo inobatsira kuti uve nechokwadi chekubatanidza kune imwe yakakodzera kifaa.
Iyi nzira yekubatanidza inogona kusiyana zvichienderana nemichina yakabatanidzwa. Somuenzaniso, kubatanidza chidimbu cheBluetooth kuPad iPad yako kunogona kusanganisira matanho akasiyana kubva kune avo kubatanidza foni yeBluetooth mumotokari yenyu .
Bluetooth Kupera
Kune zvimwe zvishoma pasi kuBluetooth. Yokutanga ndechokuti inogona kunge iri kubvisa simba rebheteri remagetsi asingasviki asina mafoni sefoni, kunyange zvazvo teknolojia (uye teknolojia yebheteri) yakagadziridzwa, dambudziko iri harina kukosha kudarika raiwanzove.
Uyewo, iyo yakareba haina kukwana, kazhinji inowedzera anenge mamita makumi matatu chete, uye semamwe ose emhando dzesayenzi, zvipingamupinyi zvakadai semadziro, pasi, kana kuti sachidziro zvinogona kuderedza huwandu huno.
Kubatana kunogonawo kuva kwakaoma, kazhinji zvichienderana nemichina yakabatanidzwa, vaiti, uye zvimwe zvinhu izvo zvose zvinogona kukonzera kushungurudzika pavanoedza kubatanidza.
Zvakachengeteka Sei Bluetooth?
Bluetooth inonzi inochengetedza isina utsi hwekombiyuta kana yakashandiswa nekuchengetedza. Ma connections akavharidzirwa, achidzivirira kushandiswa kwemazuva ose kubva kune mamwe majeri ari pedyo. Mabhidhiyo eBluetooth anoshandurawo mafaira eredhiyo kakawanda paanenge aparadzana, izvo zvinodzivirira kupinda nyore nyore.
Devices anopawo zvakasiyana-siyana zvezvirongwa zvinobvumira mutengi kugadzirisa hukama hweBluetooth. I-device-level kuchengeteka kwe "kuvimba" kadhi yeBluetooth inobvumira kushamwaridzana kune imwe chete yezvigadzirwa. Nebasa-level kuchengeteka zvirongwa, unogonawo kudzivirira mhando yemabasa yako chibvumirano chakatenderwa kupindira apo uri pahutano hweBluetooth.
Sezvo nemhando ipi zvayo yeukombiyuta, zvisinei, pane nguva dzose njodzi yekuchengetedzwa inosanganiswa. Vanotsvaga vakagadzirira kurwisa kwakasiyana-siyana kunoshandisa bluetooth network. Semuenzaniso, "bluesnarfing" inoreva munhu anokanganisa kuwana ruzivo rwakagadziriswa ruzivo rwechigadzirwa kuburikidza neBluetooth; "bluebugging" apo apo munhu anorwisa anotora foni yako nemabasa ayo ose.
Kune munhu akawandisa, Bluetooth haina kuunza dambudziko rekuchengetedzwa kwekanyanya kana rinoshandiswa nekuchengeteka mupfungwa (semuenzaniso, kwete kushamwaridzana kumadivaysi asingazivikanwe eBluetooth). Nokuda kwekuchengetedzwa kwakanyanya, apo uri munharaunda uye usingashandisi Bluetooth, unogona kuzvidzivirira zvachose.
