How does WWW work?



Functioning of the World wide web

The user uses a software known as a Web browser to request the web for a document or web page located somewhere on the web. The user types in the URL into the Web browser, who is the Client. 

The request sent by the client is managed by HTTP, and is known as as an HTTP Request. The request is sent to the Web server. The Web server is the Internet Host. The Web server forwards the request to the Application server. Application servers can be shared or dedicated. The Application server is dynamic, and has direct access to the Database server, where all the main information is stored.

The Database server sends the required documents/information back to the Application server, which sends it to the Web server. The Web server is now able to provide the required data to the Client. This is the HTTP Response. The End user receives the document on the web browser.

This is a brief and simple explanation, which merely touches the surface of how the World Wide Web actually works. The process is far more complex.
