What happens to your internet only? You have to read this article thoroughly. As this article ends, you will get all the information related to the "Internet". Let's know, What is the Internet
What is the Internet and how does it work?
Internet means a means of connecting one computer to another computer from anywhere in the world, through dedicated servers and routers.
And when two computers are connected to the Internet, they can receive or send all kinds of information. Like text, image, voice, video, etc. we can get by using the internet.
Come on, what is the Internet? What is the history of the Internet, and what is the owner angle? Why use the Internet? and how does it work? Let everyone understand this a little bit technical.
What is Internet
According to Wikipedia, the Internet is the Internet protocol suite for connecting devices around the world. , the Internet is a global system of interconnected computer networks that use the is a network of networks, which includes a global network of local, public, educational, business, and local networks.
Which is linked to a wide range of electronic, wireless, and optical networking technologies. The Internet has a wide range of information resources and services. such as inter-linked hypertext documents, the World Wide Web (WWW), electronic mail, telephony, and file sharing.
Data and information on the Internet are known to come through Routers and Servers. The router and Server connect all the computers in the world. When the message goes from one computer to another, then IP (Internet Protocol) works.
This is a protocol. Whose Protocol means "the rules for running the Internet, which is written in programming".
The Internet is actually a very large number of computer networks all over the world linked together. To make Internet communication possible, there is also a lot of hardware.
For example, there are a lot of cables (fiber-optics, copper wire) laying around the planet, from under the streets of your city to the ocean floor, and satellites have a lot of physical hardware to the satellite, which makes this communication possible.
Basics of Internet
Some basics of the Internet have been told here. This will make it easier for you to understand what is the Internet in reality.
- Internet and WWW are not the same things.
- The Internet uses the TCP/IP protocol. and a computer modem, broadband, 3G, 4G, or
- Connected through the ISP using the network.
- In the case of broadband, many computers and devices use Wi-Fi to connect to a router connected to an ISP.
- The Internet is explored, known as surfing, using a browser.
- Finding information on the Internet is achieved using a search engine.
- Users browse websites and web pages by following hyperlinks. which point to an address referred to as a URL.
- There are many computers in this, but to know their address, IP address is used, which remains the same for every computer.
- Files, pictures, songs, and videos can be shared by dwnlad (receive) and upload (send).

How does the internet work – How does the internet work?
The Internet is a global computer network for communication. Internet-only moves data from one place to another, so that we can browse, and share.
You know, there are millions of servers on the Internet. Servers store information. As such, there are file servers, mail servers, and web servers. The Internet is also made up of routers. Routers simply make connections between different systems.
for example, in your school, or college, there are many computer networks, and if your mobile is connected to the router, it means connected to the Internet.
If you want to understand deeply how the internet works? So first you have to understand ISP, IP Address, DNS, TCP / IP, WWW, HTTP, HTML, Web Page, and Web Browser. So let's know about all these.
IP Address – Internet protocol address
It is a unique identifier number. That is, each machine using the Internet has a different IP address. Because of this identifier, a computer or mobile is identified on the Internet. It has 2 versions – IP version 4 ( IPv4 ) and IP version 6 ( IPv6 ).
DNS – Domain Name Servers
Domain Name Servers are the equivalent of the Internet's phone book. Domain Name like learnncerthindi.blogspot.com or google.com, through which you get information online. And web browsers interact through Internet Protocol (IP) addresses.
DNS translates domain names to IP addresses so that browsers can load Internet resources. Domain names are user-friendly, and easy for people to remember. Computers or machines access the website based on the IP address.
TCP/IP – Transmission Control Protocol/Internet Protocol
TCP/IP is very important because the entire Internet runs on it. Because TCP/IP is a suite of communication protocols used to interconnect network devices over the Internet.
It can also be used as a communication protocol in private networks (intranet or extranet). The TCP/IP model is based on the OSI model.
HTTP – HyperText Transfer Protocol
HyperText Transfer Protocol (HTTP) is used for any application data communication. And this database is used for communication in WWW (world wide web). And use HTTP to access the files or pages of any website.
Meaning the data that you send through your browser while accessing a website, then HyperText Transfer Protocol comes to you from the server of that website i.e. the data client.
What is WWW (World Wide Web)?
Its full name is World Wide Web. And most people also think of it as the Internet. But, it is just all web pages, pictures, videos, and other online content. Which we access through a web browser.
Meaning WWW is HTML formatted and accessed via HTTP.
HTML – HyperText Markup Language
Web page development is created using HTML. Which are displayed on the world wide web. All pages contain a set of HTML tags, including hyperlinks, that are used to link to other pages. HTML is written using a version of the code.
Such as HTML in 1991, HTML 2.0 in 1995, HTML 3.2 in 1997, HTML 4.01 in 1999, XHTML in 2000, HTML5 in 2014, and HTML 5.1 in 2016 which is the latest version of 2019.
Web Page
It is a hypertext document, which is connected to the World Wide Web. A browser like Internet Explorer or Chrome is required to view the web page.
Web Browser
Browser is a software application, with the help of which we can access the information of the World Wide Web. The article you are reading right now is possible only through some web browser.
ISP – Internet Service Provider
It is a company like BSNL, Reliance Communications, etc. which provides internet to us. ISPs use fiber-optics, satellite, copper wire, and other forms to provide internet facilities to their customers i.e. us.
History Of Internet
In Internet History, 1969, it has taken its first step in the world. And till date, it is progressing due to the change in technology. Let us know Internet History in a little more detail.
Research into packet switching is one of the fundamental Internet techniques, beginning with the work of Paul Baran in the 1960s. And packet-switched networks like the NPL network by Donald Davies, ARPANET, Tymnet, and Merit network.
Telenet, and CYCLADES, were developed in the late 1960s and 1970s using different protocols.
The ARPANET project led to the development of protocols for Internetworking. Which many different networks could be included in the network.
ARPANET development started with two network nodes. which were linked between the Network Measurement Center in California, Los Angeles (UCLA) directed by Leonard Kleinrock, at the Henry Samueli School of Engineering and Applied Science, and the Network Measurement Center at SRI International (SRI) via the NLS system.
Douglas Engelbart in Menlo Park, California on October 29, 1969. The third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department.
In an early sign of future development, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks: The Heralds of Resource Sharing.
