Who invented the internet? How does it work?
Ans: This is the age of the Internet. Internet has practically revolutionized each and every façade of human life. But, how exactly internet works! Let us try to understand the Science behind it.
To start with, Vinton Cerf and Robert Kahn are credited with the invention of the Internet.
How Internet works-
Each computer connected to the Internet is part of a global network in which every computer has a unique address. Internet addresses are in the form of nnn.nnn.nnn.nnn,where nnn is a number from 0 - 255. This address is an IP (Internet Protocol) address is known as (IP Address).
The picture below shows two computers connected to the Internet. Your computer with the second computer with IP address 1.2.3.4 and IP address 5.6.7.8.
When you connect to the internet through an internet service provider (ISP), computers are connected to each other using this IP address.
When you type a domain name viz. www.gyanpoint.in in your web browser such as Google Chrome, your browser sends a request for hosting web server where the files of the website are located. When connection gets established, your browser downloads these files from that server in the form of html files or document, as well as images or videos, and renders them on to your computer screen.
This is how internet works. www in the domain names stands for World Wide Web. It acts as identifier for the web browsers.
