Internet Kya Hai?
Internet ek global network hai jo duniya bhar ke computers, servers, mobiles aur devices ko aapas me connect karta hai. Iska kaam information ko ek jagah se dusri jagah tak pahunchana hota hai.
Simple shabdon me:

Internet Ka Itihaas (History of Internet)
1. Internet Se Pehle Ki Technology
1960 ke daur me computers bahut bade aur mehange hote the. Ek computer dusre computer se connect nahi hota tha. Data share karna bahut mushkil tha.
2. ARPANET – Internet Ki Shuruaat
Internet ki foundation 1969 me rakhi gayi jab ARPANET (Advanced Research Projects Agency Network) develop hua.
- Isse US Department of Defense ne develop kiya
- Purpose: Military aur research institutions ke computers ko connect karna
ARPANET ne pehli baar packet switching technology use ki.

3. TCP/IP Protocol Ka Invention
1970–1980 ke beech Vint Cerf aur Bob Kahn ne TCP/IP protocol develop kiya.
- TCP (Transmission Control Protocol)
- IP (Internet Protocol)
1 January 1983 ko TCP/IP officially ARPANET par apply kiya gaya – isi din ko modern internet ka janm mana jata hai.

4. World Wide Web (WWW) Ka Janm
1991 me Tim Berners-Lee ne World Wide Web (WWW) invent kiya.
WWW ke main components:
- HTML (HyperText Markup Language)
- HTTP (HyperText Transfer Protocol)

Internet Kaise Kaam Karta Hai? (How Internet Works)
1. Data Packet System
Internet par koi bhi information ek sath nahi bheji jati, balki chhote-chhote packets me tod kar bheji jati hai.
Har packet me hota hai:
- Sender address
- Receiver address
- Data ka ek part

2. IP Address Kya Hota Hai?
Har device jo internet se connect hota hai uska ek unique address hota hai jise IP Address kehte hain.
Example:
- IPv4: 192.168.1.1
- IPv6: 2001:0db8:85a3::8a2e
IP address bina internet kaam nahi kar sakta.
3. DNS (Domain Name System)
DNS internet ka phonebook hota hai.
Jab aap browser me likhte ho:
DNS ise convert karta hai IP address me jaise:
142.250.195.46

4. ISP (Internet Service Provider)
ISP wo company hoti hai jo aapko internet provide karti hai.
Examples:
- Jio
- Airtel
- BSNL
- ACT
ISP ke bina aap internet access nahi kar sakte.
5. Modem Aur Router Ka Role
Modem:
- Internet signal ko digital data me convert karta hai
Router:
- Ek hi internet connection ko multiple devices me distribute karta hai
