CGI (Common Gateway Interface)

CGI (Common Gateway Interface) is a standard that allows web servers to communicate with external programs or scripts to generate dynamic content. When you visit a website with interactive features or personalized information, the server uses CGI to run programs that produce customized web pages in real-time. Essentially, CGI acts as a bridge between the web server and applications, enabling websites to respond to user inputs, retrieve data from databases, or perform other complex tasks, making web experiences more interactive and functional.
