The concept of matching arguments to parameters based on their positions is known as positional argument passing. When you pass arguments to a function in the order that the parameters are defined, it ensures that each argument is assigned to the corresponding parameter based on its position in the function call. For example, if a function is defined with parameters in a specific sequence, you must provide the arguments in the same order during the function call for them to be correctly matched.

In contrast, keyword argument passing involves specifying the parameter names along with their corresponding values, allowing for flexibility in the order of arguments. Mixed argument passing combines both positional and keyword arguments, which is also a common practice but does not adhere strictly to positional matching. Default argument passing refers to the provision of default values for parameters, allowing some arguments to be omitted when calling the function, but this does not directly relate to positional matching.
