what is

A way of presenting hardware or software resources in a standard
way – essentially as a file or filesystem.

For example:
devc-ser8250 presents the 8250 serial port as a device /dev/ser1 that
can be accessed and used like a file with open(), read(), write(), close().

mqueue presents a set of software queues as a set of devices under the
directory /dev/mqueue presents a raw block device (/dev/cd0, also a resource manager
presented by someone else) as a complete filesystem, /cd.
