[Haskell-beginners] computation vs function

[Daniel Carrera]

Hello,

I have finished the tutorial at http://ertes.de/articles/monads.html and 
my understanding of monads has increased greatly. I still need to cement 
some concepts in my mind. What exactly is the difference between a 
computation and a function? Monads revolve around computations, so I'd 
like to understand computations better.

Thanks for the help.

Daniel.
