What is a client-side script?

A client-side script is a program that is sent from a server to a user's computer and executed within the user's web browser. This type of scripting allows for interactive features and dynamic content updates on web pages without the need for additional communication with the server once the script is loaded.

When the server provides a client-side script, such as JavaScript, it runs after being downloaded to the user's device. This execution is crucial for tasks such as form validations, content modifications, and user interface enhancements, all of which contribute to a more engaging user experience. The nature of this script allows it to respond to user actions (like clicks and typed input) quickly, as it doesn't need to wait for responses from the server for immediate functionality.

The other options do not accurately describe client-side scripts. Scripts executed only on the server pertain to server-side scripting, not client-side. Scripts stored on the database server indicate a location that is irrelevant to how client-side scripts operate. Finally, the notion of a script running despite user permissions misrepresents how client-side scripts work, as these scripts depend on the user's browser configuration, which may include various security settings that can limit execution based on permissions.
