This document provides an overview of client-side and server-side scripting languages. It defines scripting languages as programming languages that support writing scripts to create dynamic web pages. Client-side scripting includes JavaScript and happens in the user's browser, while server-side scripting includes PHP and ASP and occurs on the web server. The document compares advantages of each like speed and capabilities, and notes that many sites use both for different purposes like interactivity versus data storage.

4. SCRIPTING LANGUAGES
• A scripting language is a programming language that
supports the writing of scripts
• Can create dynamic web page
Change based on user input
• For a web pages, they are instructions either to the
web browser or to the web server.

5. ADVANTAGES OF SCRIPTING
 Easy to learn and use
 Minimum programming knowledge or experience
required
 Allow complex tasks to be performed in relatively few
steps
 Allow simple creation and editing in a variety of text
editors
 Allow the addition of dynamic and interactive activities
to web pages
 Editing and running code is fast.

6. TYPES OF SCRIPTING
LANGUAGE
Client-side scripting language
Server-side scripting language

7. CLIENT SIDE SCRIPTING
• Client side scripting is used when the users browser already
has all the code and the page is altered on the basis of the
users input.
• The Web Browser executes the client side scripting that
resides at the user’s computer.
• Does not involve server processing
• Complete application is downloaded to the client browser
• Client browser executes it locally
• Are normally used to add functionality to web pages

8. CLIENT SIDE SCRIPTING
• Client side scripting cannot be used to connect to
the databases on the web server.
• Client side scripting can’t access the file system that
resides at the web server.
Examples of Client side scripting languages :
JavaScript ActionScript
Dart VBScript
Typescript

9. THE PROCESS WITH CLIENT-SIDE
SCRIPTING

10. ADVANTAGES AND DISADVANTAGES
Advantages
Allow for more interactivity by immediately responding to
users' actions.
Execute quickly because they don't require a trip to the server.
Can give developers more control over the look and behavior of
their Web widgets.
Disadvantages
Not all browsers support scripts, therefore, users might
experience errors if no alternatives have been provided.
Different browsers and browser versions support scripts
differently, thus more quality assurance testing is required.

11. SERVER SIDE SCRIPTING
• Can use huge resources of the server
• Complete all processing in the server and send plain pages to
the client
• Reduces client-side computation overhead
• The server is where the Web page and other content lives.
• The server sends pages to the user/client on request.
• Examples of Server side scripting languages :
PHP ASP
Perl Ruby

12. WHAT CAN SERVER SCRIPTS DO?
 Dynamically edit, change or add any content to a Web page.
 Respond to user queries or data submitted from HTML forms.
 Access any data or databases and return the result to a browser.
 Provide security since your server code cannot be viewed from a
browser.

13. THE PROCESS WITH SERVER-SIDE SCRIPTING

14. ADVANTAGES AND DISADVANTAGES
Advantages
It reduces the load on the user’s computer, as it does not
require plug-ins or browser scripting technology.
You can use it to dynamically create pages on the fly. New
pages can even be instantly created based on certain user
interaction.
Disadvantages
It requires the scripting software to be installed on the server.
Many scripts and CMS tools require databases in order to
store dynamic data.

15. COMPARISON
Client side scripting
• Used when the users browser
already has all the code
• The Web Browser executes the
client side scripting
• Cannot be used to connect to
the databases on the web
server
• Can’t access the file system
that resides at the web server
• Response from a client-side
script is faster as compared to
a server-side script
Server side scripting
• Used to create dynamic pages
• The Web Server executes the
server side scripting
• Used to connect to the
databases that reside on the
web server
• Can access the file system
residing at the web server
• Response from a server-side
script is slower as compared to
a client-side script

16. THE COMBINATION
Many websites use both types of scripting:
 server-side handles logging in, personal information
and preferences and provides the specific data which
the user wants (and allows new data to be stored)
 client-side makes the page interactive, displaying or
sorting data.
