What is Internet: The Internet is the network of the world's largest network. 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 Internet. By the way, I will give a little more information and this web is a kind of wire, in which information and data moves around the world. This data can be "text, image, mp3, video" out of all these, more and more gore keeps searching on text, image, MP3, video Internet.
Data and information in Net are known through Router and Server, Router and Server are connecting all the computers of the world, when the message goes from one Computer to another Computer then a protocol works named IP. (Internet Protocol), Protocol means "the rules of running the Internet which are written in programming".
Full form of internet
The full form of the Internet is Interconnected Network. Which is actually a very large network of all Web Servers Worldwide. Therefore it is also called 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.
An internet is a collection of interconnected networks, ie network of networks. It is made up of many interconnected gateways and routers connected 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. At the time of COLD WAR in 1957, the US established the Advanced Research Projects Agency (ARPA) with the aim of creating a technology to connect one computer to another.
The agency established ARPANET in 1969. With which any computer could be connected to any computer.
By 1980, his name became Internet. Vinton Cerf and Robert Kahn invented the TCP / IP protocol in the 1970s, and in 1972, Ray Tomlinson first introduced Email Network.
When did the internet start?
The Internet started from January 1, 1983. When ARPANET adopted TCP / IP in January 1, 1983, and then researchers started to assemble them. At that time it was called "network of networks", later in modern times it is known as Internet.
Definition of internet
The Internet is actually a global wide area network that connects computer systems around the world. It has 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 with the Internet, then you should 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, here too the Wi-Fi router is connected with an ISP to provide you with the Internet.
At the same time, cellular data towers also have to be connected to one Internet service provider to provide internet access to connected devices.
Internet features
Let us now know about the features of the Internet, which is very important to know.
World wide web
1. World wide web is a part of internet, which supports hypertext documents, while it allows users to view and navigate different types of data.
2. A web page is a document that is encoded with hypertext markup language (HTML) tags.
3. HTML allows designers to link together via hyperlinks.
4. Each web page has an address, which is called uniform resource locator (URL).
1. Electronic mail (e-mail) is a very popular reason due to which people use 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, it is very important for a user to have an e-mail address, which you can create and add your user name to e-mail. For example, if you want to create your account in Gmail then you can create it like username@gmail.com. Here, you have to choose a username unique which is not already available.
News
1. An Internet-based service is news, which includes many newsgroups.
2. Each newsgroup host discusses a specific topic. There are different newsgroups on all topics.
Telnet
1. Telnet is a specialized service that allows you to use a computer to access the contents of another computer with the help of a telnet host.
2. A telnet program creates a "Window" host from which you can access files, do commands issue, and exchange data.
3. Telnet is widely used by libraries so that it allows visitors to view information, to find articles, etc.
File transfer protocol
1. File Transfer Protocol (FTP) is an internet tool which is used to copy files from one computer to another.
2. Using a special FTP program or a web browser, you can log in on an ETP host computer, over the internet and also copy your computer's files.
3. FTP is very handy for finding and copying software files, 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. Just like news, there are hundreds of IRC "channels" and each is dedicated to one subject or user group.
3. If you wish, you can use a special IRC program to participate in these chat room discussion but most chat rooms are set up in the website itself, which enables visitors directly from your browser window. to chat
How does the Internet work
Computers in the Internet are connected to each other through small networks. These networks are connected by gateways with Internet Backbone.
All computers on the Internet communicate with each other through TCP / IP, which is a Basic Protocol (i.e set of rules) of 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 make that data / file / documents small The parts are broken 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 is upto 1500 characters.
Functions of TCP and IP
1. TCP's work is to break these messages into small packets which are transmit to the internet and then later they are also reassemble those small packets in the oringinal message which is received. via internet.
2. The job of IP is that it handles each part's address part, so that data can be sent to the correct address. Each gateway checks this address of the network to see where the message is being forwarded.
