What exactly is a module and why to use it?

Hello skiabox,

Actually this is explained in one of the very first pages of the "Concepts"
section:
http://www.jetbrains.com/idea/webhelp/module.html

Having used Netbeans ide, I wonder whar exactly is a module and why I
should use it in a project.

I have searched the entire site for documentation but I did not find
any answer about the use of this very basic component of the IntelliJ
IDEA platform.

So it is an xml file that describes some things about the project?

Hello skiabox,

A module is a unit of dependency management (a part of your project that
can depend on other parts, and that other parts can depend on; a module can
be independently compiled and packaged). The fact that some information about
a module is stored in an xml file is an implementation detail.

So it is an xml file that describes some things about the project?

Did you check the link to IJ web help mentioned above?
