A module is basically a set of subroutines that are
designed to do a specific set of tasks, all with a common
goal/topic. You "use" modules in your Perl code and once
you do, their functions are available to you.

Now, say you have two modules that end up having two
functions with the same name, but do two completely
different things. You need to be able to tell them apart.
That is where the module, acts like a namespace.

For example, if modules "My::First::Module"
and "My::Second::Module" both have a function called "Count
()", but you need the version from "My::First::Module",
then you would specify that when you called the function,
like so:

My::First::Module::Count(options)
{
some code;
}

Ok, that is my take on this topic. Short and sweet.
Hopefully, if there is more, and I am sure there is, that
someone will enlighten not only you, but me as well.
