The term "World Wide Web" refers to all of the publicly accessible web sites in the world, in addition to other information sources that web browsers can access. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks. It was invented by Tim Berners Lee who was a well known British computer scientist. He is the director of the World Wide Web Consortium(W3C)which oversees the Web’s continued development.

How does www works???

# The first and foremost is to know about HTML(Hypertext Markup Language). HTML helps in providing hypertext links and allows the users to see webpage associated with the websites. These hypertext links allows the users to move from one website to another.

# Typically internet follows Client/server model where web-browsers acts as client software on the remote machine. The server software is hosted on the web server which acts as host.

# A web browser contains URL(Uniform resource locators) where the visitors can specify the website they intend to see. A web browser also contains hyperlinks through which they can get connected to the webpage they want to reach. When the web browser sends the URL request using HTTP(Hypertext Transfer Protocol), then the web browser and the web server gets connected in order to get the desired result.

# An URL consists of several parts. The first part-the http:// - which is used for internet protocol. The second part is www -that tells what kind of Internet resource is being contacted. The third part-is xyz.com- for Web server identification.

# As soon as a request is sent on internet, the internet routers send them to the web servers taking the reference of the URL that is specified on the address bar. It goes to the specified web server and search for the website that is specified by the visitor.The web server then converts this request made in domain name format internally into IP address format so that the system can recognize. If any match is found then the process now occur vice versa and fetches us the required website. This whole process is termed as Domain Name Resolution.

IP addresses are binary numbers, but they are usually stored in text files and displayed in human-readable notations, such as 172.16.254.1

An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a compute network that uses the Internet Protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing.

# When the server finds the requested home page or any related informations about the website then it displays the result on the web browser.

This is how the world wide web works.
