Network Layer in OSI Model Explained | Routing, IP Address & ICMP | OSI Model Layer 3 Explained

Jab aap WhatsApp pe message bhejte ho, toh internet ko kaise pata chalta hai ki data kis city, kis country aur kis device tak pahunchana hai? Internet pe koi fixed road nahi hoti — phir bhi data sahi jagah pahunch jaata hai. 👉 Is poore process ka jawab hai OSI Model ki Network Layer (Layer 3). Is video mein hum Network Layer ko ground level se samjhenge — routing, IP address, router aur ICMP ke saath, bilkul simple Hinglish language mein. 📌 Topics Covered in This Video: OSI Model Network Layer Explained (Layer 3) Routing kya hoti hai aur kaise kaam karti hai IP Address = Internet ki identity Router kaise decide karta hai packet ka next hop Routing Table ka role ICMP protocol (ping, destination unreachable) MAC vs IP address (Data Link vs Network Layer) 🎯 Who Should Watch This Video? Computer Networks beginners Engineering students (OSI Model / CN) Networking interview preparation Anyone confused about routing, IP address aur router ka role 🧠 One-Line Memory Lock Transport Layer decide karti hai kaise bhejna hai, Network Layer decide karti hai kahan bhejna hai. Aur yaad rakho: Internet IP address se chalta hai, MAC address se nahi. ▶️ OSI Model Series – What’s Next? Next video mein hum tod ke samjhenge: 👉 Data Link Layer & Physical Layer jahan packet local network ke andar exact device tak pahunchta hai aur signals wire mein travel karte hain. Series follow karo taaki OSI Model ratta nahi, logic ban jaaye. 🔔 Support the Channel Agar Network Layer finally clear ho gayi: 👍 Like karo 💬 Comment karo: “Routing samajh aa gayi” 🔔 Subscribe for deep-clarity networking content
