What are the differences between client-side scripting and server-side scripting?
Web 2.0 applications have a server side and the choice of technologies to use server side is even more open than that client side. Client side is the user;s end of the experience, while server side is based on the server's end. As a developer, you can't impose a specific environment or browser client side because you must count on what is installed by your users and that's a severe restriction. Server side, however, you decide which platforms, operating systems, programming languages, frameworks, and libraries will be used. The choice that has the most impact on the architecture of your applications is usually the programming language. Server side, any programming language can be used to implement various Web applications and the most popular choices are scripting languages such as PHP, Perl, Python, and Ruby, and interpreted languages such as Java and C#. Client side scripts are executed and changed by the user on his side (the client side), while server side scripts are executed and changed by the user on the server. Server side scripts provide much more functionality for and by the wide variety of users (and their respective computer/browser settings) all around. Client side Scripting is possible to be blocked , where as server side scripting can't be blocked by the user , so if you validate using CLIENT SIDE only , and client side scripting blocked then even validation can not be done and directly even wrong data can be accepted and thus makes a flaw in the system.
