CGI scripts in web applications

CGI (Common Gateway Interface) scripts are small programs that run on a web server to generate dynamic content. When you visit a website and submit a form or click a link that requires personalized information or real-time data, the server uses CGI scripts to process your request. These scripts can read input, access databases, and create customized web pages before sending them back to your browser. Essentially, CGI acts as a bridge, enabling websites to provide interactive and tailored experiences beyond static pages.
