What are the two types of scripts that can run in a web application?

The two types of scripts that can run in a web application are indeed client-side and server-side scripts. Client-side scripts are executed in the user's web browser and are primarily used to create dynamic content, enhance user experience, and handle interactions without needing to communicate repeatedly with the server. Technologies like JavaScript are commonly used for these scripts, allowing for immediate feedback and actions on the user's device.

On the other hand, server-side scripts are executed on the web server. These scripts process data, handle database interactions, and generate the HTML that is sent to the client. This approach is essential for managing tasks like user authentication, form submissions, and accessing server resources. Languages typically employed for server-side scripting include PHP, Python, Ruby, and others.

The other choices present concepts that are related but do not align precisely with the question about types of scripts. Static and dynamic, for example, refer to the nature of web content rather than the location of script execution. Java and Python are specific programming languages and do not categorize the concept of script execution context. Front-end and back-end describe different parts of a web application but do not specifically denote the execution type of scripts. Therefore, the answer accurately identifies the two primary execution environments for scripts in web applications.
