Internet Kaise Kaam Karta Hai? (Simplified Guide)

 Introduction

Socho, aapne apne phone ya computer par ek button dabaya aur duniya bhar ki websites aapke saamne khul gayi. Par kya kabhi socha hai ki yeh sab kaise hota hai? Kaise ek email America se India seconds me pahuch jata hai?

Aaj hum Internet ke is jadoo ko asaan shabdon me samajhne ki koshish karenge.

Internet Ko Samajhna: Postman Aur Letters Ki Kahani

Internet ek bada network hai, jo duniya ke har kone ko jodta hai. Agar hum ise ek kahani ki tarah dekhein, toh:

1. Data Packets Ka Safar (Postman Ki Kahani)

• Jab aap Google par kuch search karte hain ya kisi website par jaate hain, toh aapka request ek data packet ban jata hai.
• Sochiye ki ye data packets ek postman ki tarah hain, jo ek message lekar duniya bhar me ghoomte hain.
• Har packet chhoti chhoti tukdon me tod diya jata hai (jaise letters). Fir yeh tukde alag-alag raste se apne destination tak jaate hain.

2. Routers Aur Servers (Post Office Aur Ghar)

• Aapka device (jaise phone ya laptop) ek router ke zariye Internet se connect hota hai.
• Router ek traffic police ki tarah kaam karta hai jo data packets ko sahi direction me bhejne ka kaam karta hai.
• Router ke baad, packets ek server tak jaate hain, jo ek bade post office ki tarah kaam karta hai. Server se hi websites aur information milti hai.

3. Signals Aur Cables (Roads Aur Traffic)

• Internet ka kaam cables, satellites, aur wireless signals ke zariye hota hai.
• Underwater cables ko sochiye ek "pani ke neeche wali sadak" ke roop me. Yeh cables continents ko jodti hain aur data packets ko duniya bhar me ghoomne deti hain.

Example: Aap Website Kaise Dekhte Hain?

1. Aapne Google pe “Taj Mahal” search kiya.
2. Aapka request ek data packet ban gaya aur router ne usse ek DNS server (Internet ka phonebook) par bhej diya.
3. DNS server ne search kiya ki “www.google.com” ka address kya hai, aur uska IP address aapko diya.
4. Fir aapka router packets ko us server par bhejta hai jaha Google ka data store hota hai.
5. Server aapko Taj Mahal ki information packets ke form me wapas bhej deta hai.
6. Yeh packets wapas ek saath judkar aapke browser me "Taj Mahal" ki website dikhate hain.

Internet Safe Aur Tez Kaise Rehta Hai?

1. Shortest Route: Data packets hamesha sabse short aur fast route dhundhte hain. Agar ek rasta block ho, toh wo alternative rasta le lete hain.
2. Multiple Copies: Har packet ki copy alag-alag jagah hoti hai, isliye data khone ke chances kam hote hain.
3. Encryption: Aapke data ko safe rakhne ke liye packets ko encrypt kiya jata hai, taaki koi third party unhe dekh na sake.

Fun Fact

• Kya aapko pata hai? Internet ka 95% kaam underwater cables ke zariye hota hai, jo continents ko jodte hain. Sirf 5% kaam satellites ke zariye hota hai.

Conclusion

Internet ek jadoo ki tarah lagta hai, par yeh kaam karta hai simple science aur engineering ki help se. Har data packet apne destination tak pahuchta hai, jaise ek postman letters deliver karta hai.
