5. How Browser Work?
The browser main functionality is to present the web 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.

6. How Browser Work? Contd.
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.
