Common Gateway Interface (CGI) is a set of standards to be implemented by web server software. The executable programs that send their output in the form of web pages are called CGI scripts

The executable scripts are similar to console applications working in a command line interface environment, although their output is rendered as HTML response.

A web server that implements CGI standard has a designated folder, typically named cgi-bin, in which these scripts are stored.
