IMO it would be clearer and more accurate to say "instance variables" 
and "methods", but otherwise this is correct.

@name is an instance variable, which you can only access in the context 
of a specific object (usually within an instance method of the class of 
that object)

Methods like 'name' and 'name=' are just methods, which in simple 
classes might just return the value of @name and set the value of @name. 
If that's all you need, then attr_* will write those methods for you. 
But they are still normal methods.
