typeclass - What's the difference between type and data type in Haskell?

Question

I'm a little confused as to the difference between a type and a data type in Haskell.

From the literature I have encountered I got the impression they were different concepts.

Answer 1

Type and data type refer to exactly the same concept.

The Haskell keywords type and data are different, though: data allows you to introduce a new algebraic data type, while type just makes a type synonym.

See the Haskell wiki for details.
