Yes, very much so! If you have a file on the device FOO: (for example), you don't have to know exactly what "FOO" is at all. It might be: - A floppy disk? - A directory somewhere on your hard drive? - A RAM disk? - The input or output of a process (a named pipe)? - A networked computer? - A handler? Here's a great example. Your floppy disk hardware, when addressed by different names, can have several totally different functions. When I address my floppy as unit DF1:, it responds as an Amiga disk drive. If I address it as MS1:, it responds as an MS-DOS disk drive! An application transparently simply the device, which transparently responds the correct way.
