A package is just a plain text file, with the extension .m, containing
some Mathematica expressions. The expressions are evaluated when you
read in the package.
In:= << "abc.m"
will read in and evaluate the contents of the file abc.m, if abc.m is in
the current directory, Directory. (But see the
MathematicaFileOrganization tutorial I mention below!)

A notebook cannot be used as a package, but (as you note below), it is
possible to maintain .m files based on notebooks.

If you have some initialization cells (Cell -> Cell properties) in the
notebook, Mathematica will ask you before saving whether you would like
it to automatically maintain a package (.m) file, with the same content
as the initialization cells. If you enable this, then the .m file will
be automatically updated whenever you save the notebook.

The .m file will be in the same directory as the .nb file.
