Parameter and Argument difference in a function or method

Parameter and Argument terminologies are quite confusing for software engineers and programmers regarding function. Difference between Parameter vs Arguments in functions or methods is very simple;

Parameter of function or method

The variable name used to store the information

Argument of function or method

The information or value supplied for parameter when calling the function

Example

function minus(x, y){
	return x -  y;
}
minus(5,2);

in the example above, x and y are called parameters whereas 5 and 2 are called their arguments, respectively.

Summary

The variable name used to store the information is called parameter where as the information or value supplied for parameter when calling the function is called the argument.
