Client-side scripting refers to scripts or code that are executed
directly on the user's web browser rather than on a web server. It is used to
create dynamic, interactive, and responsive web pages by running code on the
client device. This enhances the user experience by enabling actions such as
form validation, animations, and real-time updates without requiring a round
trip to the server.
Execution: Runs in the
user's browser.
Speed: Reduces load on
the server, as tasks are processed locally.
Languages: Common
client-side scripting languages include JavaScript, HTML, and CSS.
Use Cases:
·
Validating
user input in forms.
·
Creating
interactive elements like dropdown menus or sliders.
·
Updating
content dynamically with techniques like AJAX.
Server-side
scripting refers to scripts
or code that are executed on the web server rather than the user's browser. It
is used to process user requests, interact with databases, and generate dynamic
content that is sent back to the client. This approach is essential for
managing data, securing operations, and creating personalized user experiences.
Execution:
Runs on the web server.
Interaction:
Often used for database operations, authentication, and generating custom
content.
Languages:
Common server-side scripting languages include PHP, Python, Ruby, Node.js,
ASP.NET, and Java.
Security:
Provides better control over sensitive operations, as code is executed on the
server and not exposed to the client.
Use
Cases:
·
Authenticating
user logins.
·
Retrieving
and displaying data from a database (e.g., user profiles, search results).
·
Generating
customized web pages or reports.
·
Managing
business logic and backend processing.
Example:
When
you log into a website, the server checks your credentials in the database,
processes the login request, and sends a response (e.g., redirecting to your
dashboard). All of this happens through server-side scripting.
