Working of World Wide Web
what is World wide Web?
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. These other sources include FTP sites, USENET newsgroups, and a few surviving Gopher sites.
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 webpages 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 webserver 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 webserver 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 Webserver identification.
# As soon as a request is sent on internet, the internet routers send them to the webservers taking the reference of the URL that is specified on the address bar. It goes to the specified webserver and search for he website that is specified by the visitor.
# 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.
