Internet in a nutshell

Internet was created in 1990 by CERN physicist Tim Berners-Lee and became free to use by everyone in 1993. The free internet meant that anyone can publish documents and make them publicly  accessible to everyone in the world via a public Internet Protocol (IP) address. These IP addresses , used to locate files and documents on the internet , are further referenced by Uniform Resource Locator (URL) or web addresses (like example.com) that are easy to remember . The publicly accessible document is often referred to as a webpage and collection of webpages is called a website. Modern webpages are written in html including various css styles , scripts or images and hosted on one or more web servers which are basically computers that have publicly accessible webpages or files.
"He wove the World Wide Web and created a mass medium for the 21st century. The World Wide Web is Berners-Lee's alone. He designed it. He loosed it on the world. And he more than anyone else has fought to keep it open, nonproprietary and free."
