The answer to this question is a little complex; I will try to simplify it:

Multithreading: an environment/hardware architecture that allows the efficient execution of multiple threads (i.e., independent programming units): http://en.wikipedia.org/wiki/Multithreading_(computer_architecture)

Parallel programming: multiple threads solve simultaneously a problem to improve performances (e.g., searching the solution of a math problem, sort a list with quicksort)

Asynchronous programming: usually it is used with slow tasks and when you don't want to lock other tasks of your application. For example, you want that the UI of your application remains responsive while downloading something from the Internet.

Like the answer in this thread said, Multithreading is parallel, but Parallel Programming is not necessarily multithreading.

And Multithreading is the base of Asynchronous Programming.

And what's the relationship between Parallel Programming and Asynchronous Programming? Please take a look at this thread:http://stackoverflow.com/questions/12434369/what-is-the-relation-between-asynchronous-and-parallel-programming-in-c
