8.3 Understanding Client-Server Scripting

In a client-server model, two computers work together to perform a task. A client computer
requests some needed information from a server computer. The server returns this information
and the client acts on it. The internet runs on a client-server model. With internet the server is a
particular Web server and the client is a Web browser.

A web server is a computer that contains all the web pages for a particular web site and has
special software installed to send these web pages to web browsers that request them.
The following steps occur when a web browser visits a static web page:

 The client (web browser) locates the web server specified by the first part of the
URL(www.something.com)

 The client then requests the static web page specified by the second part of the URL
(/index.htm)
 The web server sends the contents of that particular file to the client in HTML format.

 The client receives the HTML sent by the server and renders it for the user.

Task But client and server script are generally independent. Analyze what does the
author wants to say from this statement? Give examples to support your answer
