Yes.  All kinds of things are presented as files, even though they aren't
really.  (Even `tasks': every live process has a directory under /proc
which contains `files' with information about the running process.)

Originally it was just devices like printers, disks, tapes and memory.
With the /proc filesystem, you also have things like lists of interrupts
and network parameters.  All these things are presented as files, so that
you can use routines like open() on them.
