Bluetooth kya hai aur kaise kam karta hai?


Bluetooth ke vishay men kon nahin janta, sabhi ko pata hai ki ye Bluetooth kya hai (Bluetooth in Hindi) aur kaise kaam kartaa hai. kyunki aksar ye feature ko aap lagabhag sabhi mobile phones men dekh sakte hain. Data transfer karne kaa ye ek bahut hi bdhiyaa tarikaa hai. abhi ke samay men eske bahut jyaadaa application hone ke kaaran se ye Bluetooth hamare jivan ka ek hissa ban gaya hai. chaahe vo audio devices hon, yaa mobile phones, home stereos, MP3 playerslaptop, desktop, tables etyaadi. aap kisi bhi electronic device kaa naam len aur aapko vahaan jarur bluetooth najar aayega.vo chaahe koi bhi device ho sabhi ko data transfer karne ki jarurat pdti hai. aap apne smart phones se dusre kisi phones ko agar data (audio,graphics,image,files,videos) bhejnaa chaahen tab ye aap bluetooth ke maadhyam se kar sakte hain. lekin esmen jo sabse mahatvpurn chij hain vo ye ki donon devices men bluetooth ki suvidhaa honi chaahia. yahaan main aap logon ko Bluetooth kyaa hai, uske prkaar, eske advantages aur disadvantages ke vishay men jaanenge. yadi aapko Bluetooth ke vishay men puri jaankaari praapt karni hai tab aapko es article ko puri tarah se pdhnaa hogaa. to phir binaa deri kiye chaliye shuru karte hain aur jaante hain ki aakhir ye blututh kyaa hoti hai aur eske kitne prkaar hain.
Bluetooth ek aisi wireless technology hai jiskaa istemaal electronic devices ke bich data transfer karne ke lia kiya jata hai. agar ham dusre wireless communication modes ki baat karen tab unke tulnaa men yahaan data transmission hone kaa distance bahut kam hotaa hai. eskaa matalab ki bahut hi kam durtaa ke bhitar hi data trasfer ho saktaa hai bluetooth men. es technology ke estmaal se users ko koi bhi cords, cables, adapters ki jarurat hi nahin pdti hai aur ye unhen wirelessly hi communicate karne ki permission prdaan kartaa hai.
Ye Bluetooth ek prkaar kaa Wireless technology hai, jiskaa estmaal koi bhi file yaa data transfer karne ke lia kiyaa jata hai. es Bluetooth technology ko develop Bluetooth special interest group ne kiyaa aur eski physical range hai 10m se lekar 50m tak hi. ye Bluetooth device jyaadaa se jyaadaa saat devices men hi connect ho saktaa hai aur enkaa mukhy estmaal smartphones, personal computers, aur gaming consoles jaise industries men kiyaa jaataa hai. IEEE ne Bluetooth ko standardized kiyaa hai IEEE 802.15.1 ke rup men, lekin yah standards keval kuchh hi periods ke lia maintain kiya jata hai

Bluetooth Technology key features kya hai
Aaiye jaante hain ki aakhir es bluetooth technology men aise kyaa key features hain jinke vishay men aap sabhi ko jarur jaannaa chaahia
.
Less complication : esmen jyaadaa complication nahin hoti hai, ye bahut hi simple technology hai.
Less power consumption : esmen jyaadaa power ki consumption nahin hoti hai. jo ki ese jyaadaa popular banaataa hai.
Cheaper Rates : dusre similar technologies ke tulnaa men ye jyaadaa saste hote hain.
Robustness : – ye bahut hi robust hote hain. kahin aur kabhi bhi enkaa estmaal kiyaa jaa saktaa hai.
Distance: enkaa estmaal 10 se 50 meters tak ke bich kiyaa jaa saktaa hai.
Data rate: enkaa data rate hotaa hai 1 Mbps tak. jo ki bahut hi fast hotaa hai.
Spreading: esmen FHSS (Frequency Hopping Spread Spectrum) technology kaa estmaal hotaa hai.
Bluetooth ke Advantages
yahan par men aap logon ko Bluetooth ke advantages ke vishay men bataane vaalaa hun.
➨ eske estmaal se aap binaa kisi wires ke hi immediately adhoc connection ke maadhyam se connect ho sakte hain. yahaan par connection establishment honaa bahut hi aasaan aur quick hotaa hai. User ko keval devices ko pair karnaa hotaa hai.
➨ esmen low power consumption hotaa hai.
➨ Data Transfer divaaron ke bich se bhi ho saktaa hai.
➨ eski range Infrared communication ki tulnaa men behatar hoti hai.
➨ chunki ye Bluetooth SIG ke dvaaraa manage kiyaa jaataa hai aur bahut se bde companies ke products ko ye cover kartaa hai esalia interoperability ki samasyaa yahaan n ke baraabar hotaa hai alag alag bluetooth vendor ke products ke bich.
➨ eskaa estmaal voice aur data transfer ke lia hotaa hai.
➨ chunki es technology men FHSS kaa estmaal hotaa hai esalia yahaan par data communication bahut hi secure hotaa hai.
➨ es technology kaa estmaal bahut se products jaise ki head set, car system, printer, web cam, GPS system, keyboard aur mouse men estmaal hote hain.
➨ chunki aajakal bluetooth headphones market men mehjud hain, esaliy koi driver chaahe to phones ko aaraam se receive kar saktaa hai gaadi chalaate vakt. esse use driving men koi bhi dikkat nahin hogi.
➨ ye Bluetooth devices bahut hi kam daamon men upalabdh hotaa hai jise har koi kharid sakte hain.
➨ esmen bahut hi kam interference hoti hai agar ham dusre wireless technologies ki baat karen tab kyunki esmen FHSS technique laa estmaal hotaa hai.
Bluetooth ke Disadvantages
Jaise sikke ke do pahalu hote hain vaise hi sabhi chijon ke advantages aur disadvantages bhi hote hain. to chalia bluetooth ke disadvantages ke vishay men jaanne ki koshish karte hain.
➨ eskaa jo sabse bdaa disadvantage vo ye ki eski security. ji haan kyunki jaise ki ham jaante hain ki ye Radio frequency par operate kartaa hai aur esalia ye divaaron ko aasaani se penetrate bhi kar saktaa hai. esalia aapko ye advise diyaa jaataa hai ki aap eskaa estmaal critical business yaa personal data transfer ke lia n hi karen.
➨ chunki HomeRF technology bhi esi frequency par operate karti hai, esalia kayi baar ek dusre ke saath interference bhi huaa karti hai.
➨ eski bandwidth kaaphi lower hoti hai WiFi ke compare men.
➨ esmen Battery usage jyaadaa hoti hai jab bluetooth ON ki stithi men hoti hai. esalia ye recommend kiyaa jaataa hai ki estmaal n hone par bluetooth ko band kar den, jisse mobile ki battery life bhi bdh jaati hai

Bluetooth Network kya hai aur iske prkaar
Bluetooth network us network ko kahaa jaataa hai jahaan ki bahut saare bluetooth users aapas men jude hua hote hain aur communicate kar rahe hote hain. en networks men mukhy rup se do hi mukhy element hote hain pahlaa Master aur dusraa Slave.
Mukhy rup se do prkaar ki hi network topologies ko jyaadaa ahamiyat di gayi hain Bluetooth men.
1) Piconet
2) Scatternet.
Piconet tab form hotaa hai jab one master aur one slave mehjud ho yaa phir one master aur multiple slaves mehjud hon. jyaadaa se jyaadaa maximum 7 active slaves hi rah sakte hain piconet men. esalia jyaadaa se jyaadaa 8 maximum devices ek saath ek chhote se network men saath communicate kar sakte hain aur jinhen ki piconet kahaa jataa hai. Slaves keval tab hi transmit karte hain jab ki master bluetooth device unhen kuchh request kare tab. lagabhag 255 slaves hameshaa parking state men mehjud hote hain.
Active slaves ko poll kiyaa jaataa hai master ke dvaaraa transmission karne ke lia. pratyek station ko keval 8 bit parked address hi praapt hotaa hai. esalia total 255 parked slaves hi possible hote hain ek piconet men. ye parked station keval 2 ms ke bhitar hi join kar sakte hain. baaki sabhi stations ko join hone men samay lag saktaa hai. keval 10 aise hi piconets kisi nirdhaarit bluetooth radio coverage area men paaa jaate hain.
Scatternet Multiple Piconets ke Combinations ko Scatternet kahaa jaataa hai. A device multiple piconets men participate kar saktaa hai. ese timeshare karnaa pdtaa hai aur current piconet ke master ke saath synchronize bhi honaa pdtaa hai.
Ye un data rate ko support kartaa hai jo ki alag alag versions par aadhaarit hote hain jo ki kuchh esaprkaar hai 720 kbps se 24 Mbps tak. ye 1 se 100 meters tak ke durtaa ko cover kar paane ki kshymtaa rakhte hain jo ki depend kartaa hai ki vo us bluetooth device ke kis power class ko support kartaa hai
