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 keep on roaming around the world. This data can be "text, image, mp3, video" out of all these, 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 is written in programming".
Full-Form Of Internet
The full form of the Internet is an 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 the 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?
The Internet started on 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 the "network of networks", later in modern times, it is known as the Internet.
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.
Wherein 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
1. The World Wide Web is a part of the Internet, which supports hypertext documents, while it allows users to view and navigate different types of data.
2. Whereas a web page is a document that is encoded with a hypertext markup language (HTML) tags.
3. HTML allows designers to be linked together via hyperlinks.
4. Every web page has an address, which is called a uniform resource locator (URL).
E-mail
1. Electronic mail (e-mail) is a very popular reason due to which people use the internet.
2. To create, send, and receive e-mail messages, you need an e-mail program and an account in an Internet mail server with a domain name.
3. To use e-mail, a user needs to have an e-mail address, which you can create by adding your username to e-mail. For example, if you want to create your account in Gmail, then you can create like username@gmail.com. Here you have to choose a slightly unique username that is not already available.
News
1. There is Internet-based service news, which includes many newsgroups.
2. Each newsgroup hosts discussions on a specific topic. There are different newsgroups on all topics.
Telnet
1. Telnet is a specialized service that allows you to access the contents of another computer using a computer with the help of a telnet host.
2. Creates a telnet program on a "Window" host so that you can access files, issue commands, and exchange data.
3. Telnet is widely used by libraries so that it allows visitors to view information, find articles, etc.
File transfer protocol
1. File Transfer Protocol (FTP) is an internet tool that is used to copy files from one computer to another.
2. Using a special FTP program or a web browser, you can log in to an ETP host computer, over the Internet and copy files to your computer.
3. FTP is very handy to find and copy software files, while you can do the same with articles and other types of data types. Universities and software companies use FTP servers so that they can allow visitors to access data.
Internet Relay Chat (IRC)
1. Internet Relay Chat (IRC) is a service that allows users to communicate with each other in real-time by typing text in a special window.
1. Like news, there are hundreds of IRC "channels" and each one is dedicated to a single subject or user group.
3. If you wish, you can use a special IRC program to participate in these chat room discussions, but most chat rooms are set up on the website itself, which enables visitors directly from their browser window. to chat.
What is an 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 the 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 the Internet and Intranet?
Here you will know what is the difference between the 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 modes 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 that 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 the Internet and Intranet?
1. Where the Internet provides unlimited information that can be viewed and used by anyone, whereas in the Intranet, data circulates only within the organization.
2. The Internet can be accessed by everyone and everywhere, whereas Intranet can be used only by authenticated users.
3. The Internet is not owned by any single or multiple organization, whereas Intranet is a private network, comes under a firm or institution.
4. Internet is a public network so it is available to everyone, whereas Intranet is a private network so it is not available to everyone.
5. Intranet is much safer than the Internet.
How does the Internet work?
Computers on 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 on 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 up to 1500 characters.
Functions of TCP and IP
1. 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 in the original message which are received. via internet.
2. 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
Talking about the history of Net, in 1969 it used to take its first step in the world, and due to the change of time and technology, it went ahead and is not taking the name of stopping now. Know a little more.
So let's go ahead to know the history of the Internet in Hindi.
1. Internet originated from ARPANET (ADVANCE RESEARCH PROJECT AGENCY network).
2. ARPANET was part of the Defense Department of Ameriaca in 1969.
3. Initially 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 five US universities. 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 was reached and changed throughout the year, and now you know what is the Internet through this Internet and you are studying the history of the Internet. Were.
Internet access
1. For exchanging electronic mail
More than 85% of people connected to the Internet use the Internet to send and receive email. More than 20 million emails are exchanged in a week.
2. To do research
Internet is a very big source of documents, books, research papers, etc. That's why people use it to do their research.
3. Can Download or Upload Files
Here many such files are uploaded through many websites such as Movies, Songs, Videos, Documentaries, etc. If you want to watch them then you have to download them which requires the internet.
4. Having Discussion Groups

You can get all kinds of things here at a very good offer price. You just have to register yourself on these sites. Then you can shop as much as you want.
Types Of Internet
There are many types of Internet connections so that you can connect a personal electronic device to the Internet. All these connections use different hardware and each has a different range of connection speeds.
As changes are coming in technology, faster internet connections are needed to handle such changes. That's why I thought that why should be told about the type of Internet Connection so that you can know about all these options.
What is Dial-Up Connection (Analog 56K)
Dial-up Connection is the most basic form of Internet connection. It consists of a telephone line that is connected to multiple users (as opposed to a dedicated line) and which is connected to a PC that has access to the Internet.
Dial-up access is very cheap but at the same time equally slow. A modem (internal or external) connects with the Internet once the computer dials a phone number.
In this, the analog signal is converted into digital via a modem, and then it is sent to a land-line service through a public telephone network.
Telephone lines can be of many quality and at the same time, the connection can also be bad at times. In this, the lines regularly experience a lot of interference and it affects their speed, which ranges from about 28K to 56K. Since a computer or other device share the same line of telephone, so both cannot be active at the same time.
What is DSL Connection?
The full form of DSL is Digital Subscriber Line. This is an internet connection that is always "on". It uses 2 lines so that your phone is absolutely free when your computer is connected.
DSL is a wired connection that transmits data through traditional copper telephone lines that are already installed in homes and businesses.
In this, you do not need to dial any number to be connected to the Internet. DSL uses a router to transport data and its connection speed range depends on the service, which ranges from about 128K to 8 Mbps.
The speed and availability of DSL service depend on how far your home or business is from your nearest telephone company facility.
What is Cable Connection?
Cable provides internet connection through a cable modem and it operates through cable TV lines.
Uploading and Downloading have different transmission speeds. Since coaxial cables provide more bandwidth than dial-up or DSL telephone lines, you get faster access here.
The cable connection speed range is between 512K to 20 Mbps.
What is Fiber Connection?
In this Fiber Connection, fast-fiber optic cables go directly to your home or office and provide you a more stable, efficient, and reliable connection than hybrid copper and fiber systems.
It is capable of supporting broadband speed up to 1Gbps, at such a speed that it can play an HD TV program in just five seconds.
Fiber optic technology converts electrical signals that are carrying data into light and sends the same light through transparent glass fibers whose diameter is the same as that of a human hair.
Fiber transmits data at very high speeds that are much higher than current DSL or cable modem speeds, typically in tens or hundreds of Mbps. This FTTP connection is not shared with anyone else. At the same time, this is a very valuable option.
What is Wireless Connection?
Wireless, or Wi-Fi, as the name suggests, does not use telephone lines or cables to connect to the Internet. Wherein it uses radiofrequency.
Wireless Connection is also always on and it can be accessed from anywhere. The coverage areas of wireless networks are gradually increasing. At the same time, its speed range is from 5 Mbps to 20 Mbps.
What is Wireless DIA (Direct Internet Access)?
Dedicated Internet Access means that a specified amount of bandwidth is specified for your use only. This is a dedicated amount that is only for your use.
Here you are not sharing anything with anyone, but you definitely have a direct connection with the Internet Superhighway.
Where the speed of another internet connection also depends on how many people are connected to that internet connection, but it does not matter because dedicated bandwidth is already provided in it.
What is Satellite Connection?
Satellite accesses via the internet in the orbit of a satellite's Earth. In this, since the signal has to travel such a large distance from the earth to the satellite and back again, so it provides a delayed connection as compared to cable and DSL. Satellite connection speed ranges from 512K to 2.0 Mbps.
What is a cellular or mobile technology connection?
Cellular technology provides wireless Internet access through cell phones. Speeds can vary according to the service provider, but the most common are 3G and 4G speeds only.
Here 3G describes a 3rd generation cellular network whose mobile speeds are around 2.0 Mbps.
Whereas 4G stands for the fourth generation of cellular wireless standards. Although the goal of 4G is to achieve a peak mobile speed of around 100 Mbps, in reality, it is currently available only up to 21 Mbps.
Whereas 5G has been available only in a few places and is mostly in the testing phase.
How is the internet operated?
Here we will know how you can run the internet on your computer and mobile device.
How to play the internet on mobile?
Smartphones, such as iPhones and Android phones, are very small handheld computers with built-in GPS and cameras. At the same time, for many people, their SmartPhone is the only tool to access the Internet.
Most smartphones use two different technologies to access the internet – the first is the cellular network that the user has to subscribe to, such as Airtel, Jio, Idea, etc. The other is Wireless Connection.
In this, the biggest advantage of Cell Network is that you can get Internet access anywhere and anytime. Whereas in a wireless network, you need to be near the modem to get better speed because it has a coverage area.
How to run the internet on a computer or PC?
If you want to run Internet on your computer or PC, then you have to either take the broadband connection from any ISP or can also take any wireless connection from them. By using this, you can access the Internet on your computer.
On the other hand, if you do not have that much money, you still want internet access, then you can also get internet access by using your Smartphone as a hotspot.
Benefits of internet
If you use the Internet properly, then you can do a lot, so read the benefits of the net given below and make your life digital.
1. It is more helpful in giving social networking, education, entertainment, online information on a large scale.
2. It will save your time and you can learn a lot if you want.
3. Using this, we can find any information very easily. Like we do in Google.
We can easily send messages, audio, video, documents to anyone on the Internet like everyone does on Whatsapp, Facebook, Twitter.
4. If we talk about studies, nowadays everyone can study online and do research.
5. And the best advantage - Online services like Online Shopping, Online Recharge, Movie Ticket Booking, Internet Banking, Online Transaction, all this has been possible only because of the Internet.

11. You will keep getting the news of every moment whenever you want, along with it, you will also get information about science, technology, on the Internet.
12. You can store all your data in it and download it back whenever you want.
This is also very beneficial for the government, the government has been able to reach people easily through its scheme Internet.
Loss Of Internet
If you want to run your life in the right way in this digital world, then definitely read these things carefully, and tell others
1. The disadvantage of this is its addiction, if you get caught then you will keep following it and will it be a waste of your time.
2. In this, anyone writes and shares anything, whether it is right or wrong, due to which wrong information reaches people.
3. Through this, anyone can steal all your data from your computer through hackers.
4. Sometimes any wrong video(mms) spreads very fast in the net, this is also a loss.
5. Computer Virus can reach your computer from the Internet itself, due to which all your data can disappear and also slows down your computer.
6. A lot of pronography sites are in the net, in which obscene pictures and videos remain and they have a very bad effect on the mind of the children.
7. In this, in the social sites like Facebook, Instagram, some people leave a picture of anyone, this is also a disadvantage of the Internet.
8. There are some websites on the Internet in which people ask you some questions and take all the information and they take wrong advantage of it.
9. Just as it saves your time by using the Internet, it also wastes your time.
Development Of The Internet
Here I have tried to show the evolution of Internet or Evolution of Internet. At the same time, I have systematically shown it in its timeline according to its development.
July 1945
Vannevar Bush published his essay "As We May Think" in Atlantic Monthly. This was the first picture in which the human mind had started thinking ahead. At the same time, that seed of giving real form to the Internet and the World Wide Web had just settled in the minds of people.
October 4, 1957
Sputnik was launched. Only after the launch of Sputnik did the U.S. The government felt that they should make a network that could protect them from any military attack. Paul Baran, who belonged to RAND Corporation, proved that a packet-switching, distributed network is the best design ever. His ideas were put to work and data could be transferred to some mainframe computers across America.
December 9, 1968
At the same time, the biggest victory came when Douglas Engelbart and his team at the Convention Center, San Francisco demonstrated a working hypertext system, word processing, video conferencing that too over a network, computer mouse and more.
It really made a big impression in the field of computing and internet.
October 29, 1969
The first connection was made to a packet-switching network between Stanford and UCLA. Here two mainframes used interface message processors (IMPs) to send a message. The first message that was sent in the Internet was "lo" because the system crashed in the letter g of the login itself. This network later became ARPANET.
September 1971
ARPANET implemented a terminal interface processor (TIP), which allowed computer terminals to remote access networks. This helped ARPANET to grow a lot by making connections easier.
1971
Ray Tomlinson sent the first email to himself through separate machines through a network. He could not remember the message he had sent. He chose an @ sign to separate the user from the host – this practice is still used in email addresses.
December 1, 1971
Michael Hart spent his time at the Materials Research Lab, University of Illinois, to store books and documents in the public domain, so that it became free to access. The first document that was typed was Declaration of Independence.
1974
Telenet was launched, which became the first pay-for-access Internet that was available to the public.
1980
Usenet was launched by Tom Truscott and Jim Ellis. It was working in a different protocol than existing networks at that time, and it represented the earliest use of the Internet as a source for public news and bulletin-board-style posts.
1983
MILNET was split off from ARPANET which now started working only according to a military-only Internet. It was unclassified and was mostly used to send emails between bases.
January 1, 1983
This was the historic day when ARPANET was moved to TCP/IP, a suite of protocols designed by Robert Kahn and Vint Cerf. Even now TCP / IP is called the language of the Internet.
1984
At the same time, the Domain Name System (DNS) was introduced, so that the host received a meaningful name and not a numerical address that was used earlier.
March 1989
Tim Berners-Lee wrote a proposal that later became the World Wide Web. They had to do everything themselves initially, such as formalizing the language of documents (HTML), protocols for accessing them (HTTP) and creating the first web browser/editor (which was confusingly named WorldWideWeb).
Later many people joined this project to make it better.
1991
1. Tim Berners-Lee launched the first web browser and web page. This web page described Web and HTML, which allowed others to create more sites for themselves.
2. Gopher was released to help people search the Internet for a specific content using a menu-based interface. Later Gopher was replaced by algorithmic search engines such as Google and directories such as Yahoo, but at that time its main task was to find information from the Internet.
1993
Mosaic was released, which was a graphical web for the general public. Marc Andreessen, a creator of Mosaic, created Netscape Navigator and influenced the creation of the Internet, which now went beyond just text.
October 1994
Netscape Navigator was released in beta form. Its official version 1.0 was released in December and this browser became popular all over the world for the World Wide Web.
1995
Secure sockets layer (SSL) encryption was introduced by Netscape, which has now made online business secure using credit cards. This innovation helped in starting e-commerce.
September 15, 1997
As a domain registered to Google.com. At the same time, its search engine went live in the year 1998 and both became big with time.
December 17, 1997
Jorn Barger named this term web log which referred to a collection of online links which he "logged" from the Internet. This term was later shortened to “blog”.
January 9, 2001
iTunes was launched. Apple's online music store changed the music industry. Where each individual track was sold for 99 cents.
February 2004
Facebook was launched from a Harvard dorm room. This social media site had more than 5 million users by the end of 2005 and it made a user base of about 500 million users by 2010.
January 9, 2007
The iPhone was unveiled, which led to the birth of the smartphone in the phone industry and mobile computing gradually became popular.
July 7, 2009
Google announced the Google Chrome OS project. It was an open-source project that focused on creating a stable, fast OS that would be used by users as a client interface for web-based applications and not for running applications on local computers.
What did you learn today?
I hope that you must have liked this article of my What is Internet?. It has always been my endeavor to provide complete information about the definition of internet to the readers, so that they do not have to search any other sites or internet in the context of that article.
This will also save their time and they will also get all the information in one place. If you have any doubts about this article or you want that there should be some improvement in it, then you can write low comments for this.
