@user is an instance variable and for if you want to use the variable anywhere in your program, user is a local variable and works only in the method it was written in, User would be the name of a class you create. Hope this helps!

P.S. If any of this does not make sense it will be explained in later ruby courses.

@user - instance variable

user - local variable

User - name of the whole class

To understand the first two, you have to learn about variable scope. To understand classes, you have to know how object-oriented programming works.
