What's the difference between an argument and a parameter?

Question

When verbally talking about methods, I\'m never sure whether to use the word argument or parameter or something else. Either way the other people know what

Answer 1

Logically speaking,we're actually talking about the same thing. But I think a simple metaphor would be helpful to solve this dilemma.

If the metaphors can be called various connection point we can equate them to plug points on a wall. In this case we can consider parameters and arguments as follows;

Parameters are the sockets of the plug-point which may take various different shapes. But only certain types of plugs fit them.
Arguments will be the actual plugs that would be plugged into the plug points/sockets to activate certain equipments.
