What is INTERNET – Who Invented and How It Work

Internet
Internet is a network of computers spanning the globe. This communication structure is a system connecting people all around the world.

The Internet began in 1969 as the U.S. Department of Defense’s Advanced Research Project Agency (ARPA) to provide immediate communication within the Department in case of war.

A global Web of computers, the Internet allows individuals to communicate with each other. Often called the World Wide Web, the Internet provides a quick and easy exchange of information and is recognized as the central tool in this Information Age.

How Internet Work


The Internet acts as a pipeline to transport electronic messages from one network to another network. At the heart of most networks is a server, a fast computer with large amounts of memory and storage space.


One of the greatest things about the Internet is that nobody really owns it. It is a global collection of networks, both big and small. These networks connect together in many different ways to form the single entity that we know as the Internet.

Since its beginning in 1969, the Internet has grown from four host computer systems to tens of millions. However, just because nobody owns the Internet, it doesn’t mean it is not monitored and maintained in different ways.

The Internet Society, a non-profit group established in 1992, oversees the formation of the policies and protocols that define how we use and interact with the Internet.

An Internet Service Provider (ISP) such as BSNL, Airtel allows the user access to the Internet through their server. Many teachers use a connection through a local university as their ISP because it is free.
