Do the input queue and output queue belong to the terminal device, its driver, or line discipline?

In APUE, where should the input queue and output queue (shown in the first figure) appear in the second figure? For example,
- in "actual device"
- in "terminal device driver"
- in "terminal line discipline"
- somewhere between two of the above three?
Thanks.
We can think of a terminal device as being controlled by a terminal
driver, usually within the kernel. Each terminal device has an
input queue and an output queue, shown in Figure 18.1.
Most UNIX systems implement all the canonical processing in a module
called the terminal line discipline. We can think of this module
as a box that sits between the kernel’s generic read and write
functions and the actual device driver (see Figure 18.2).
