Hi
mount is the command used to know which devices are
loaded.it means devices like floppy drive,cd drive.if we
give mount command it will display which device is mounted.
unmount is the command used to disable the device.if we
give umount and the path of the device then it will umount
the device.
In windows we wont have this concept.because those are
installed.

Let me know if i am wrong
