resource you choose, by requesting it from the server and
displaying it on the browser window.
 The resource is usually an HTML document, but may also
be a PDF, image, or other type.
 The location of the resource is specified by the user using a
URI (Uniform resource Identifier).
 As You Write URL and hit GO button browser program
sends a request (Could I have the web page please?) to a
web server program running on the remote computer.
 The server program, gathers the request from the web
browser, tries to hunt for the web page and then
formulates a response.
How Browser Work?

10.  If server was able to locate the web page, it sends the
HTML file to the web browser.
 The browser picks up all the information coming in from
the server and does its best to display the web page.
 A typical web page not only has text but also images and
these are separate files that need to be transferred from
the server to the browser.
 The browser-server communication goes on till all the files
have been transferred to the browser.
 After that Browser-server connection is disconnected and
Web Page is Displayed on the browser window.
