Hi Rana,
The advantage of having all devices as files is that you can write to just
about any device using the same "write" system call.
It basically provides an abstraction layer so that the programmer need not
be unnecessarily concerned about the device details.
For device specific features, you have "fcntl". So you get the best of
both worlds.
