As soon as you connect your computer to the Internet, you also become a part of the Internet.
History of Internet History of Internet
Internet surfaced in 1969. When the US Department of Defense started a project called ARPANET (Advanced research projects Network), the purpose of this project was to interconnect computers of the US Department of Defense and various universities. Belonged to it. It was started. It started with the exchange of information and messages between those engineers, scientists and researchers, but it expanded very rapidly.
In the mid-1980s, another organization National Science Foundation created a new network for academic and engineering research called NSFNet. Its capacity was more than ARPANET. Only researchers were allowed to connect to this network. And no business was allowed on it. Seeing the need of this, many private companies also formed their own networks which later joined ARPANET and NSFNet and thus the Internet was born. This process was called Internetworking. Hence it was named INTERNET.
ARPANET was stopped in 1990 and NSFNet was stopped in 1995 from giving government assistance. But the Internet continued to function as before because many commercial Internet services had started, other functions in the Internet continued because many commercial Internet services had started and other services and users were added to the Internet and it is still expanding. .
How does the internet work? How does the internet work?
Because the Internet is a network of networks, generally no user can be directly connected to it. Instead they are connected to a small network that is connected to the backbone of the Internet through a gateway. The Gateway is one such device. Which connects two different types of networks. A backbone is a central structure that connects two or more networks.
Internet is a very large network spread through the sea, which is spread all over the world. It is also called the internet in Hindi.
Working of internet
A computer (gateway or server) connected to the Internet is identified by a name or address. You can send any data, information or message from any computer in the network to another computer. Each information sent is broken into several smaller parts, which are called packets. Each packet is sent separately and when all are received, the original information is created by adding them. To run the Internet smoothly, it is necessary that every computer connected to it follow the same rules of communication. Groups of such rules are called protocols. The communication protocol used by the Internet is TCP / IP (TCP / IP). This protocol is in two parts. The first part is TCP: Transmission Control Protocol, which is responsible for distributing a file or message in packets in the source computer itself. It is also responsible for creating the original message by re-connecting the packets received to the receiving computer. The second part IP (Internet Protocol) is responsible for handling the address of the receiving computer so that each packet is sent in the correct way. These two protocols together are called TCP / IP: Transmission Control Protocol / Internet Protocol.

Q. What is DNS?
Ans. Its full name is Domain Name System. It is a system of determining the address of websites on the Internet. In this, each website is given a different name. Which is called U R L.
Q. What is U R L?
Ans. A uniform research locator is the address of a computer or website in the Internet. And it identifies any website correctly.

Q. What is a Domain ID?
Ans. It is part of the U R L of a website. It states the type and purpose of the website. For example - the domain ID (.com) appended to the URL of a website indicates that it is a business website. Similarly, a website with org domain id tells which non-profit organization.
