File extension cgi is related to the The Common Gateway Interface. CGI is a standard for interfacing external applications with information servers, such as HTTP or Web servers.

A plain HTML document with Perl or C source code that the Web daemon retrieves is static, which means it exists in a constant state: a text file that doesn't change. A CGI program, on the other hand, is executed in real-time, so that it can output dynamic information.
