What is a network bridge - Networking Hindi me

Jab bhi kisi road ka construction hota hai or jab kisi river ke upar se jana ho to Bridge ki need hoti hai. So clearly bolne ka means ye hai ki Bridge ka kaam two ends ko jodne(milane) ka hota hai.

Same in Computer networking ki baat karte hai to waha bhi Bridge same kaam karta hai. Computer Networking me Bridge two or more LAN(Local Area Networks) ko add(milane) karne ka kaam karta hai. Bridge bhi Routers ke jaise he hote hai, lekin ye kisi bhi data ko analyse nahi karte hai bas data packets ko aage forward karte hai. Isliye bridge bhut he fast hote hai or networking devices ke comparision me kyuki ye seeche data ko forward karte hai. Lekin Bridges Router jitne versatile nahi hote hai.

For example: Bridge can't be used as a firewall, jaise ki routers ko as a firewall use kiya jata hai. Bridge data transfer karta hai different-different protocols ka use karte(tockens and ethernet network) ke beech or Bridge operate hota hai OSI Model ki 2nd layer me "Data Link Layer". So bridge ke baare me basic idea to mil he gya hoga ki ye kaha kaam karta hai or Bridge kya hota hai?

Bridges important role play karte hai data filteration me, jisse ki trafiic load kam ho jata hai or data transfer fast hota hai. Bridge data ko "data packets" me divide karta hai. Bridges are passive devices.

Network Bridge work kaise karta hai(How network Bridge works)

Let's discuss Bridge work kaise karta hai. Ye interview question bhi hai. Bridge incoming network traffic ko inspect kata hai, or ye decide karta hai ki data packets ko aage forward kare ya unko discard kare. Packet forwarding and discarding destination par depend karti hai.

Network bridge OSI Model layer 2 me work karta hai jo ki Data Link Layer hai. Ye other network ko is layer me connect karta hai. Bridge only traffic broadcast he nahi karta hai sath me bridge traffic control bhi karta hai. Bridges bridge table ka use karte hai frames ko send karne ke liye across the network. Starting me bridge table blank hota hai, jaise-jaise frames receive ya send hone lagte hai ye table source and destination ka MAC address store karti hai.

Bridge Data Sending Process

1. Agar destination node, network segment ki same side me hai jaha se frame receive ho raha hai, to bridge us frame ko block kar deta hai network segment me jane se. This is known as "Filtering".

2. Agar destination node another network segment me hai, tab bridge frames ko forward karta hai appropriate network segment me.

3. Agar destination address he unknown hai, tab bridge us frame ko sabhi network segments me forward kar deta hai except source address. This is known as flooding.

Types of Network Bridge

• Transparent Bridges
• Source Routing Bridges
• Transparent Learning Bridge
• Transparent Spanning Tree Bridge
