What is Internet ?

The Internet is the world’s largest network of networks. It is a global computer network that provides many types of information and communication facilities.

It is actually a very large network of interconnected networks and together they use standardized communication protocols to stay connected with each other.

This network is called media or transmission media in the language of the Internet. By the way, I will give some more information, this net is a kind of wire, in which information and data keeps on roaming around the world. This data can be any of these “text, image, mp3, video”, more often text, image, mp3, video are searched on the Internet.

Data and information in the net come through routers and servers, routers and servers connect all the computers in the world, when the message goes from one computer to another, then a protocol works whose name is IP. (Internet Protocol), Protocol means “the rules for running the Internet which are written in programming”.

Full form of internet:

The full form of Internet is Interconnected Network. Which is actually a very big network of all Web Servers Worldwide. Therefore it is also called the World Wide Web or simply the Web in many places.

This network includes many such private and public organizations, schools and colleges, research centers, hospitals as well as many servers all over the world.

Internet is a collection of interconnected networks, i.e. network of networks. It is made up of many interconnected gateways and routers being connected to each other all over the world.

Who discovered the internet:

It was not just a matter of one person being able to invent the Internet. Many scientists and engineers were needed to make it. In 1957, at the time of COLD WAR, America established the Advanced Research Projects Agency (ARPA) whose purpose was 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 computer.

By the year 1980, its name became Internet. Vinton Cerf and Robert Kahn invented the TCP/IP protocol in the 1970s, and in 1972, Ray Tomlinson first introduced the Email Network.

When did the 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 was internet started in India?

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

Definition of internet

The Internet is actually a global wide area network that connects computer systems around the world. It consists of many high-bandwidth data lines which are called the “backbone” of the Internet. These lines are connected with major Internet hubs that distribute data to other locations, such as web servers and ISPs.

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 via a cable, DSL, or fiber connection. When you connect to the Internet via a public Wi-Fi signal, the Wi-Fi router is also connected to an ISP to provide you with the Internet.

Whereas cellular data towers also have to be connected to one or the other Internet service provider to provide internet access to the connected devices.

Features of the Internet:

Let us now know about the features of the Internet, which are very important to know.

World Wide Web

What is intranet?

Intranet is such a private network that is often seen in a single enterprise. It usually consists of many interlinked local area networks and also uses leased lines in a wide area network.

Typically, an intranet has only one or more gateway computers connected to the external Internet.

The main job of Intranet is to share the information and computing resources of a company only among the employees. Whereas intranet can also be used for teleconferences between working groups.

Whereas intranet uses TCP/IP, HTTP, and other Internet protocols. That’s why it usually looks like a private version of the Internet.

What is the difference between Internet and Intranet?

Here you will know what is the difference between Internet and Intranet.

Meaning of Internet
Internet is a global network that establishes a connection and provides transmission to many different computers.

It uses both wired and wireless mode of communication to send and receive any kind of information such as data, audio, video etc. In this, data often travels through “fiber optic cables”, which are owned by telephone companies.

In today’s time, almost everyone uses the Internet to get information, for communication, and for transferring data into the network. It is a public network using which computers can easily connect and relay with each other. It provides a very good source of information to the users.

Meaning of intranet
Intranet is a part of the Internet which is privately owned by any one organization. It interconnects all its computers and provides access to all its files and folders within the network itself.

It also has a firewall that surrounds the system, so that it prevents any unauthorized user from accessing the network. Only authorized users have permission to access this network.

At the same time, Intranet is used to connect computers and transmit data that too within a company network. This is a secure way to share details, materials, and folders because the network is very secure and restricted within the organization itself.

What is the difference between Internet and Intranet?

Where the Internet provides unlimited information that can be viewed and used by anyone, whereas in the Intranet, data circulates only within the organization.

  • Internet can be accessed by everyone and everywhere, whereas Intranet can be used only by authenticate users.
  • The Internet is not owned by any single or multiple organization, whereas Intranet being a private network, it comes under a firm or institution.
  • Internet is a public network so it is available to everyone, whereas Intranet is a private network so it is not available to everyone.
  • Intranet is much safer than the Internet.

How does the Internet work ?

Computers in the Internet are connected with each other through small networks. Wherein these networks are connected through gateways with the Internet Backbone.

Whereas all computers communicate with each other on the Internet through TCP/IP, which is a Basic Protocol (i.e set of rules) of the Internet.

TCP / IP (Transmission Control Protocol / Internet Protocol) manages all the transmission happening in the Internet, no matter what the data / file / document is, but to do this, they have to convert that data / file / documents into small pieces. It has to be broken into parts which are called packets or datagrams.

In this, each packet contains the address part of the actual data, i.e addresses of destination and source upto 1500 characters.

Functions of TCP and IP :

The job of TCP is that it breaks the messages into small packets which are transmitted to the internet and then later they are also reassembled, those small packets are received in the original message by internet.

The job of IP is that it handles the address part of each part, so that the data can be sent to the correct address. Each gateway checks this address of the network to see where the message is being forwarded.
history of internet
