What Is The Internet? History And Development

The Internet is the most revolutionary invention of the modern era which has changed every aspect of human civilization. It is not only a medium of information and communication, but has also become an infrastructure in the fields of education, health, business, entertainment and social interaction. As of 2023 about 67% of the world’s population is using the Internet, reflecting its global impact.

Definition: Internet (Internet) is derived from the term “Interconnected Networks”, meaning “networks connected in mutual”. It is a vast network of computer networks around the world that are interconnected using TCP/IP protocols and facilitate data exchange.

History And Development Of The Internet

The story of the development of the Internet begins in the 1960’s. Let us know its main stages:

The history and development of the Internet dates back to the 1960’s. 1969 saw the establishment of the ARPANET, the first packet switching network created by the U.S. Department of Defence. In 1971 the first email was sent and Ray Tomlinson used the @ sign for the first time. In 1983 the TCP/IP protocol was adopted, which led to the foundation of the modern Internet. In 1989 Tim Berners Lee invented the World Wide Web (WWW) and developed the structure of HTML, HTTP and URL.

Commercial use of the Internet grew rapidly in the 1990’s, and it was during this time that large companies such as Yahoo (1994), Amazon (1995) and Google (1998) were founded. The 2000’s saw the dawn of Web 2.0 and the era of social media, with the emergence of Facebook (2004), YouTube (2005) and Twitter (2006). This was followed by a period of mobile internet and smartphones in the 2010’s, with 4 G technology and Android and iOS platforms consolidating their worldwide foothold.

Technologies such as 5 G, artificial intelligence (AI), Internet of Things (IoT), metaverse and cloud computing made the Internet more advanced and faster in the 2020s.

History Of Internet In India

Internet in India started on 15 August 1995 when VSNL (Videsh Sanchar Nigam Limited) first started public internet service. Internet was very expensive in the early stages and had very low speeds (about 9.6 kbps). The situation improved with the arrival of private ISP companies in the 2000’s, but the real revolution happened after the arrival of Jio in 2016 which introduced cheap and fast internet in India.

How Does The Internet Work?

To understand the functioning of the Internet we need to know some fundamental concepts:

1. Client-server model

Works on Internet client-server architecture. When you open a website on your mobile or computer:

Client: Your device (such as smartphone, laptop) that sends requests
Server: Remote computer that stores website data and sends responses
Protocol: TCP/IP – Rules for data transmission

2. IP address and DNS

IP Address (IP Address): Each device connected to the Internet has a unique numerical address (such as 192.168.1.1 or 2001:0db8:85a3:0000:0000:8a2e:0370:7334). It is the address of the device through which data is sent and received.
DNS (Domain Name System): This is the Internet’s “phone book” that translates domain names (such as com) into IP addresses. For example, when you type “www.google.com“, the DNS server changes it to an IP address such as 172.217.166.110.

3. Data transmission

All data on the Internet is broken into small packets and sent. In each packet:

IP address of source and destination
Packet number (sequence number)
Actual data
Code for error checking

These packets travel through various routes to reach the destination and are reconnected. The TCP protocol ensures that all packets arrive in the correct order.

4. Internet Infrastructure

The following components are important for the Internet to work:

Fiber optic cables: cables laid from the sea level that connect continents
Routers and switches: Turn data packets in the right direction
Data Centers: Huge server form where data from websites and apps is stored
ISP (Internet Service Provider): Companies like Jio, Airtel, BSNL that provide connectivity to the end user

FAQs

Q.1 What is the difference between the Internet and the World Wide Web (WWW)?

The Internet and WWW (World Wide Web) are often used interchangeably, but these are different concepts:
The Internet and the World Wide Web (WWW) are understood by many to be the same, but the two are different concepts. The Internet is a vast global web of computer networks, beginning with the ARPANET in the 1960s. In contrast, the World Wide Web is a hypertext document system, invented by Tim Berners Lee in 1989.
The Internet is used for many services such as sending emails, file transfers via FTP, voice calls, and video conferencing. WWW is primarily used to access websites and web apps. The Internet runs on the TCP/IP protocol, while the basis of the WWW is the HTTP and HTTPS protocols.
Internet can be considered physical infrastructure—such as wires, routers, servers, etc—whereas WWW is a service running on the Internet, such as a road vehicle. There are many more services on the Internet besides WWW, such as email (SMTP), file transfer (FTP) and voice calls (VoIP).

In simple words, the Internet is a road so WWW is a car running on it. Other services run on the Internet such as email (SMTP), file transfer (FTP), voice calls (VoIP), etc.

Q.2 Who discovered the Internet?

The Internet did not develop by any one person but through the collective efforts of many scientists and engineers. Some major contributors:

Licklider: Introduced the concept of “galactic network” in 1962
Paul Baran: Proposed packet switching technology
Bob Kahn and Wint Surf: developed the TCP/IP protocol
Tim Berners Lee: Invented the World Wide Web (WWW)
ARPANET (1969) is considered the ancestor of the Internet which was developed by ARPA (Advanced Research Projects Agency) of the U.S. Department of Defense.

Q.3 Who owns the Internet?

There is no single owner or controller of the Internet. It is a decentralized network which various organizations manage together:

ICANN (Internet Corporation for Assigned Names and Numbers): Allocates domain names and IP addresses
IETF (Internet Engineering Task Force): develops technical standards
ISOC (Internet Society): promotes the development and use of the Internet
ISP (Internet Service Providers): Companies like Jio, Airtel that provide connectivity to the end user
