The sentence is incorrect in part. The sentence would read better as: An object can be called a collection if it is able to supply a reference to a related object that implements IEnumerator. The object calling itself a collection must also implement the IEnumerable interface. The IEnumerable interface sets up a contract that the object must have a method called GetEnumerator() which returns an object that implements IEnumerator IEnumerator is used internally with in a foreach loop to get at all the elements in a collection. This is still not the full story, but it does go some way to explaining what that sentence means.
