The processing takes place on the end users computer.
The source code is transferred from the web server to the users computer over the internet and run
directly in the browser.
The scripting language needs to be enabled on the client computer.
The problem with client-side scripts is the limit of control and problems with operating systems
and web browsers.
Languages:- JAVASCRIPT
VBSCRIPT
PYTHON
ACTION SCRIPT
Server side :-
The server-side environment that runs a scripting language is a web server.
A user's request is fulfilled by running a script directly on the web server to generate dynamic
HTML pages. This HTML is then sent to the client browser
It is usually used to provide interactive web sites that interface to databases or other data stores on
the server.
Server-side programming can also be encrypted when users send form variables, protecting users
against any hack attempts.
server-side programming languages are C#, VB.NET, and PHP, ASP, RUBY,JAVASCRIPT, PYTHON
