The Internet is a huge network that works to connect many computers and electronic devices of the world with each other. Data can be easily sent from one computer to another computer connected to the Internet.

Internet can be connected to many devices like Computer, Mobile, Smart TV, Gaming Control apart from Wired Connection to Wireless Network.

When two or more computers are connected together, it is called a network. In the same way, there are many small networks like Private Schools, Colleges, Businesses, Governments and the Internet does the work of connecting these networks, so the Internet is also called the Network of Networks.

Who discovered the internet?

Many people contributed to the discovery of the Internet. Leonard Kleinrock first planned to equip the US Defense Department with a new technology during the Cold War in 1957. Under this plan, many computers were to be connected and information were to be carried from one place to another. So that the soldiers can get the necessary information very easily.

In 1969, ARPANET (ADVANCE RESEARCH PROJECT AGENCY Network) was created so that any computer could be connected to any computer.

By the time of the 1980s, its name became the Internet. Vinton Cerf and Robert Kahn invented TCP/IP. Together they published a paper in 1974. The name was “The Fathers of the Internet”. Vint Cerf is called the father of the Internet because of publishing this research paper.

Full Form of Internet

The full form of the Internet is Interconnected Network. It is also called International Network, which is a network of very large networks, hence it is also called “Huge – Network”. In many such places it is also called the World Wide Web or simply The Web.

The data available on the Internet is controlled by the Protocol. Through TCP/IP a file is divided into many smaller parts by the file server. Which are called Packets.

History of the Internet

In 1969, the University of California and the University of Utah in Los Angeles started the ARPANET (Advanced Research Projects Agency Network). The main goal of this project was to connect the computers of various colleges, schools and the US Defense Ministry among themselves. It was the world’s first packet switching network.

In the mid-80s, another federal agency, the National Science Foundation, created a new high-capacity network, the NSFnet, which was more capable than the ARPANET. The only drawback in NSFnet was that it allowed only educational research on its network, no private business of any kind was allowed. For this reason, private organizations and people started building their own networks, after which the Internet was formed by joining ARPANET and NSFnet.

Dial-up is a means of connecting to the Internet with the help of a pre-existing telephone line. Whenever the user initiates the dial-up connection, the modem first dials the phone number of the Internet Service Provider (ISP). Which is designed to receive dial-up calls and then the ISP establishes the connection. Which normally takes 10 seconds. Generally, the term ISP is used for those companies. Which provides Internet Connection to the users.

For example, the names of some famous ISPs are- Airtel, MTNL, Vodafone etc.

Broadband provides users with the facility to connect to the Internet at high speed through dial-up connection. Broadband also includes various types of High-Speed ​​Transmission Techniques, which are as follows

(a) Digital Subscriber Line (DSL)

It is a popular broadband connection, in which Internet access digital data is transmitted by wires of a local telephone network. It is similar to a dial service, but works at a much faster rate. For this a DSL modem is required, to which the telephone line and computer are connected.

(b) Cable Modem

Under this, Cable Operators also provide Internet facilities through Coaxial Cable. Its transmission speed can be 1.5 Mbps or more.

(c) Fiber Optic

Fiber optic technology converts the data present in the form of electrical signals into light form and sends that light to the receiver through transparent glass fiber, whose diameter is approximately equal to that of a human hair.

(d) Broadband over Power Line

Broadband over power line is the service of broadband connection on low and medium voltage electric power distribution network, it is suitable for areas where no other medium is available other than power line. Example- Rural Area etc.

(i) TCP: It converts the message into a set of packets near the sender. Which is collected back to the receiver and the message is retrieved back. It is also called Connection Oriented Protocol.

(ii) IP: It allows different computers to communicate among themselves by establishing a network. Handles the task of sending packets over the IP network. It maintains the address of packets on the basis of many standards. Each IP packet contains the source and destination address.

(b) File Transfer Protocol (FTP): Through this protocol Internet users can upload files from their computers to various websites or download them from the website to their PC. Examples of FTP software are Filezilla, Kasablanca, ftp, Konqueror etc.

(c) Hypertext Transfer Protocol: It ensures that messages are formatted and transmitted in some way and what action the web server and browser will take in response to various commands. HTTP is a stateless protocol, because each information in it works independently.

(d) Hypertext Markup Language: It is used for designing web pages. Markup language is a set of markups (< – – >) tags. Which tells the web browser how to display words, images, etc. to the users on the web page.

(e) Telnet Protocol: Telnet session is started on entering valid username and password. It is a network protocol, in which bidirectional text-oriented communication is provided over a local area network using a virtual connection.
