In statically typed languages, you have to declare the types of
variables. Instance variables are one example, and are defined in the
class typically.

Ruby is dynamically typed, you don't declare variables or their types
before hand. Assigning to a variable makes it exist.
So for instance variables, they come to existence when a method is
invoked that assigns to an instance variable.
Example:

class A
  def test
    @value = 3
  end
end

a = A.new

Now a, which is a local variable, exists, and it references an object
that is an instance of class A. Inside this object, no instance
variable exists yet. Now:

a.test

At this point, the instance variable @value has been created inside
the object referenced by a.

Hope this clears up your confusion a bit,

Jesus.
