OSI Layer Ki puri Jankari Hindi me

OSI Model ki vishodhan 1984 me huyi the  , 1977 Me ISO ( International standard organization ne ek Comity  banayi  Aur Usee Ye responsibility Di ki Ekk Open Standard Develop kiya jaye , Esi comity ke Kehne par 1984 me (OSI) model Approve kiya gaya ” Open ka matlab ye hai ki yaha par jo bhi Ess model ko follow karege ,Wender , Manufacture, unke Device Aapse me Inter-operate kar sakte hai

OSI model Aane Se pehle bahot se Wender Specific Model Istimal karte the jaiase ki IBM Aapne computer bana ta tha Aur Un Computer ko Connect kar ne ke liye  Aapna Networking Standard Istimal karta tha , Esi Tarah Use Samay ke Aur bhi company jo Computer bana te -the bo bhi Aapne-Aapne Computer ko connect karne ke liye Apne hi protocol Istimal karte the , Leki Problem  Vaha Hoti the jab 2 ya 2 se  Aadhik Wender,s ke computer Ekk company Kharid leti thee, to unke Aapas me Inter-operate karne me dikkat Aati theee , to Ess Problem ko Door kar ne ki liye Jo Sabse Bada badlaw hua bo  “OSI ” Model ka tha  Eska Result 1984 me OSI model ke ratification se hi huaa , Aur bo tabhi se hi Computer Network design me Ekk Reference  model ke Hisab se Istimal kiya jata hai
 

 

OSI model Ye bata tha hai ki kaise Network protocol Aapas me Kam karenge ya communicate karenge ,Aagar Hum Aaj-kal ke Technology ko dekhe to ya Jo devices hum istimal karte hai bo En model ke According Nahi hai ,Fir Bhi Ye Network ke design ko Samzane ke liye Bahot hi Useful hai

  Hindi me OSI layer ke bare me jante Hai

 

OSI layer

 

Dosto OSI layer me First Layer

 

  1.  Physical
  2.  Data Link
  3.  Network
  4.  Transport
  5.  Session
  6.  presentation
  7. Application

 

OSI Model Ne Ess tarah Network ko 7 Part me Aalag kiya hai Aur hur Layer ki Ekk Aapni responsibility Hoti hai Aur Enn 7 Layers ko OSI Model Kaha jata hai ,

Enn Layer ko 2 part me bhi Alag kar sakte hai  Upper Aur Lower” Application ,   presentation, Session ( En 3 Layer ko Upper Layer Kahte hai ) Aur Transport ,Network , Data link , Physical ko Lower Layer kaha jata hai

Dosto Aagar generally Bath kiye to jo Task en Layer par perform kiye jate hai  Wo kisi Application Specific hote hai jaise ki Lower Layer Networking ke liye hote hai ( Routing, Addressing ,Flow Control ke liye hote hai ) Uske Example hai : TCP/Ethernet to chalo Jante hai ki OSI model ne En 7 part ko Kiss taraha Design kiya hai 

 

Layer Off OSI model in Hindi

 

1) Physical Layer in hindi :- Mechanical,Electrical, yane Ki Physical media hai bo kaisa hoga kis level par Voltege jayegi ye 2) Data Link Layer in hindi  :- Physical Addressing , Network Topology ,Error, notification, sequencing kya hota hai Enn Sab bare me  bath ki jati hai

 

3)Network Layer in hindi:– Network Layer Bade hi important Function perform karti hai ye Routing And internet ka kam karti hai (Subnet traffic Control ,packet ,logical-physical Address  mapping etc.)

 

4) Transport in hindi:-Message Segmentation , Connection Control ,Service-point Addressing , Error Correction  ke liye Work karti hai

 

5) Session Layer in hindi :- Session ko control karti hai Session Establishment se lekar Session Control karne ka sara kam Session layer ka hota hai


 

6) Presentation layer in hindi :-Encryption ,compressing , Translation or data  Conversion par kam karti hai


 

7) Application Layer in hindi :– Application ke bich me Yane ki Koe User istimal kar raha hai jaise ki Koe e-mail Application hai Ya Smtp ya Koe Bhi  Application Service ho to Uski Responsibility  layer 7 ki hoti hai
