What is the primary function of server-side CGI scripts?

The primary function of server-side CGI (Common Gateway Interface) scripts is to process user inputs from web forms. When a user submits data via a web form, the CGI script on the server processes that data, performing operations such as validation, database interaction, and generating dynamic content based on user input. This capability allows for the creation of dynamic and interactive web applications where user interaction is integral to the website's functionality.

CGI scripts can handle various programming languages and can produce output that is sent back to the user's web browser. This functionality is critical for building applications that respond to user needs and actions in real-time.

While creating interactive websites is a broader concept that involves both client-side and server-side elements, the specific role of CGI scripts is centered on processing input, rather than solely managing web server settings or handling client-side scripting, which is typically associated with languages like JavaScript executing in the user's browser. Therefore, the distinction lies in the script's capability to take, process, and act upon user input from the server-side perspective.
