Cgi-bin

From HostPedia

The "cgi-bin" folder is a special folder on a web server where excutable files can be placed and executed. placing Perl, Python and C/C++ scripts are to be placed in the "cgi-bin" directory in order to grant them the proper permissions to execute.

Note: the “bin” part of “cgi-bin” is a shorthand of the word “binary”, because in the past, most programs were referred to as “binaries”. Now days, it is more common to place executable scripts in the "cgi-bin" folder.
