What is Internet? The Internet is a network of computers that can be accessed from any connected device. It began 1969 as a way of sharing information among scientists and has evolved over the years.

In this section, we will discuss what the internet is, its history and how it has evolved overtime. We will also find out how it has changed our lives and what we can expect for its future. In this section, we will explore how the internet has changed our lives, as well as what you can expect for its future. Let’s know what is called internet.

What is Internet?

The Internet is a worldwide (interconnected) network of computers. The internet consist of many local, national International networks. All these networks are interconnected. It provides access to information and data from all over the world. Wherever you are in the world, you can easily access any information available on the internet. The internet is a network of computer networks that used the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a global system meaning that it has no central control or governing body and is not constrained by physical boundaries.

Internet has been around since the 1970s and was created by the Defence Advanced Research Project Agency (DARPA). It was designed as a way for researchers to share information with each other without having to travel long distances. Hope you have understood what is internet.


What is the old name of Internet?

ARPANET (Advanced Research Projects Agency Network) eventually evolved into what we now call the Internet. Despite its success, ARPANET membership was limited to if you academic and research organisations with Defence Department contracts. 

Full form of Internet

The full form of internet is Interconnected Network. This is actually a huge network of all Web Server Worldwide. That’s why it is also called Worldwide Web or simply the Web in many places. This network includes many such private and public organisation, schools and colleges research centres, hospitals as well as many servers all over the world. Internet is a collection of interconnected networks that is of network of networks. It is made up of many interconnected gateways and routers being connected to each other all over the world.

History of Internet

Talking about the history of Internet, in 1969 it used to take its first step in the world and due to the change of time and technology it grows very fast. So let’s know further the history of internet.

1. Internet originated from ARPANET (Advance Research Project Agency Network).

2. ARPANET was part of the Defense Department of America in 1969.

3. In the beginning, this network was created to send secret letters through computer, its name was ARPANET.

4. Initially, this idea was used to connect the computers of 5 US Universites. By the decade of 1972, it was connected to 23 nodes of the world and different countries of the world, which was later named internet.

5. In the beginning, this network was used as a private network, later it reached everyone and it was changed your after year and now you are reading information about what is the internet and the history of the internet through the internet.

Who invented the Internet?

It was not just matter of one person being able to invent the Internet. Many scientists and engineers were needed to make it. In 1957 during the time of cold war America established the Advanced Research Project Agency (ARPA), whose purpose to create a technology so that one computer could be connected to another computer.

In 1969, this agency established ARPANET. So that any computer could be connected to any other computer. By the year 1980, its name became internet. Vinton Cerf and Robert Kahn invented the TCP/IP protocol in the 1970’s and in 1972, Ray Tomlinson first introduced the Email Network.

When did Internet start?

Internet started from January 1, 1983. When ARPANET adopted TCP/IP on January 1, 1983, and after that researchers started assembling them. At that time it was called “network of networks”, later in modern times it is known as Internet.

When did Internet start in India?

Internet services was made publicly available in Indian on 14 August 1995 when it was launched by state-owned Videsh Sanchar Nigam Limited (VSNL).

What is the definition of Internet?

The internet is actually a global wide area network that connects computer system around the world. It consists of many high-bandwidth data lines which are called the “backbone of the internet”.

Whereas, if you want to connect to the internet, then you must have access to an Internet Service Provider (ISP), which acts as a middleman between you and the Internet.

Most ISPs provide broadband Internet access by a cable, DSL or fibre connection. When you connect with the internet through a public Wi-Fi signal here also the Wi-Fi router is connected with an ISP to provide you the internet. At the same time cellular data towers also have to be connected to one out the other internet service provider to provide internet access to the connected devices.
