Hello friends.....

   Aaj hm baat krenge dual camera k concept k bare me ki kis tarah se dual camera wale mobile phone kaam krte hai. Aajkal makets me dual camera k bahut sare mobile phone aa chuke hai. Ab to mid range k mobiles me v dual camera dekhne ko mil rha hai. Dual camera wale kuchh mobile phones hai jaise ki HTC one M8, Honor 6X, Iphone 7, etc. Dosto dual camera wale mobile sabse pahle lounch kiya tha HTC and LG ne 2011 me. 2011 me HTC EVO 3D and LG OPTIMAS 3D lounch huye the jinme dual camera ka support tha.
       Dual camera ka concept bahut hi simple sa hai. Isme jo first primary camera hota hai wo to ek normal picture ko hi click krta hai but jo secondary camera hota hai wo yaha pr us picture ko enhance krta hai or kisi na kisi tarah se picture quality ko improve krta hai. ye improvment kisi v tarah ka ho skta hai jaise ki picture me blur effect dalna jaise ki ham koi picture ko capture krte hai or usme hmara subject to focus m rahta hai but jo background hota hai wo blur ho jata hai. Or kisi mobile me jo secondary camera hota hai usse hm wide angle shot le skte hai. or jaise ki ham kisi dual camera k mobile phone se sharp picture click kr skte hai yaha pr sharp ka means hai ki jaise ki kisi primary camera se capture ki gayi picture me kisi tarah se pixels me koi kami aa jati hai to jo secondary camera hai wo hamari picture me pixels ko fill kr deta hai. iss tarah se hame bahut hi achhi picture dekhne ko milti hai.

     Ab hm baat krte hai HTC EVO 3D or LG OPTIMAS 3D k bare me to inme jo dual camera lge the unka alignment thoda sa oposite tha isliye hm inse ek 3D picture ko capture kr skte the or yaha pr jo display di gyi thi wo v ek 3D display thi to isliye hm ek 3D picture dekh skte the.

     To dosto mai ummeed krta hu ki aap dual camera k cocept ko smjh chuke honge. Agar ko querry ho to aap comment kr skte hai.

About Proxy in hindi

About Proxy-

Dosto apne proxy k bare m jaroor suna hoga. Aaj ham proxy k bare m janenge. Proxy ka work
ek mediator ki tarah hota hai. Ye ek user or web k bich m mediator ka kaam krta hai. Jb
koi website kisi dusri website ka copyright documents ko bina permission k users ko 
uplabdh krati hai to government us website ko bann kr deti hai. Aisi websites ko ham proxy
se open kr skte hai. Proxy kuchh had tk hamari identity ko chhupane m v kaam krti hai. Pr
jyada der tk hm apne identity ni chhipa skte kyoki ye ek hi layer hoti hai hmare or web k
bich m agar is proxy layer ko koi hata de to ham direct web ko access krenge or hmari IP
identify ki ja skti hai.
Proxy ka use office, colleges, cyber cafe etc. m kiya jata hai. Jaise ki kisi
college m students k liye facebook surf krna mana hota hai to uss college m facebook ki
website pr proxy lga dete hai or koi use surf nhi kr pata.
Iss tarah jo websites government dwara bann hoti hai unko ham kisi dusri country
ki proxy se open kr skte hai. Agar koi website india m bann hai to sayad china m bann na
ho or agar ham china ki proxy use kre to ham uss website tk pahuch skte hai.

About DNS DOMAIN NAME SYSTEM, DNS SPOOFING, AMPLIFICATION ATTACK in hindi

Hello friends

About DNS.....

ham baat krenge DNS k bare me ki DNS kya hota hai. DNS ka poora name hai Domain Name System. Jaisa ki apko v pta hoga ki sabhi website ki apni ek alag IP hoti hai jisse uss website ki pahchan hoti hai or uss IP address se ham uss website tk pahuch skte hai.To jab ham apne browser me kisi website ko open krte hai to hamara computer DNS server ko query bhejta hai or reply me DNS server hame uss required website ka IP address send krta hai or ham uss website ko open kr pate hai.
jaise ki ham apne browser k URL bar me 'www.google.com' search krte hai to hamara computer sbse pahle DNS server ko request send krta hai or sbse pahle ye request root DNS server k pass pahuchti hai or root server k pass bahut sare alag alag server hote hai ex.- .com,.org, .in etc. to root server inme se .com server ko pahchanta hai or query .com server ko send krta hai. Uske baad .com server k pass v bahut sare alag alag server hote hai ex.- facebook, google etc. to yaha pr google server ko choose krta hai or fr google server k pass v bahut sare server hote hai jaise ki mail.google.com. www.google.com etc. to yaha pr google server www. server ko choose krta hai or fr complete query ki information user tk pahuchata hai. or iss tarah hamara website open ho jati hai.

About DNS Spoofing.......

Dosto ab baat krte hai DNS Spoofing ki. jaisa ki abhi hamne jana ki DNS hame query ki information send krta hai to hamara v to koi prmanent address hoga jisse ki hamari pahchan ho skti hai. Means hamara v ek IP address hota hai. To agar hamara IP address koi chori kr le to jab ham kisi website ko surf krenge to hamari query uss person tk jayegi jisne ki hamari IP address ko chori kiya hai iss person ko hm hacker v bol skte hai. Or fr jab uss hacker k pass hamara address hai to fr wo hame koi v information send kr skta hai.jaise ki agar hamne facebook.com k liye query send ki hai to hamre pass wo page open hoga wo reality me facebook.com ka original page ho hi na or hacker hamse hamri sari information uss fishing page se le lega. Iss tarah se koi hacker hamari IP ko spoof krke hamri koi v information le skta hai fr chahe wo kisi facebook account ki detail ho ya fr chahe kisi bank account ki detail ho.

ABOUT DNS AMPLIFICATION ATTACK

Dosto ab ham baat krenge Amplification attack k bare me. Iska direct connection hai DNS spoofing se. Isme jo hacker hota hai wo hamari IP ko spoof krke hamari hi IP address k 4-5 computer bna leta hai or ek sath alag alag website k liye sabhi computer se DNS server ko request send krta hai. Ab DNS server ko lgta hai ki alag alag website ki information mangi gayi hai to wo sabhi websites ki information send kr deta hai. Kyoki wahi same IP hamare computer ki v hoti hai to itni sari websites ki information hamare computer me ek sath aa jati hai or fr hamara browser use smjh nhi pata hai or koi v webpage ko open nhi kr pata hai. Iss tarah ham tb tk kisi website ko open nhi kr skte jb tk ki wo Amplifiction attack hamre computer m ho rha hai.
