Wikipedia has a nice description:
http://en.wikipedia.org/wiki/Parameter_%28computer_science%29#Parameters_and_arguments

Short view - technically, parameters are the variables in the function
and arguments are the values given to the variables at the point of
call. So outside the function, it is more common to talk about
arguments. Inside the function, you can really talk about either.

Parameters that will take on the value of the arguments passed to the function.

Arguments.

Not really, it is not an important distinction.
