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.

The browser picks up all the information coming in from the server and does its best to display the web page.

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.
