Describe the mount and unmount system calls?

Answer Posted / vinay

"mount" is used to avail the file system which we want to
access , "unmount" is used to unavail the file system
in case of removable file system like floppy/cd if don't
execute mount command these file system will not be
available to user and once they mounted if we want to
remove them from respective drives we have to unmount them
then only we can eject them out from respective drives.
eg. $mount /mnt/floppy
$ umount /mnt/floppy
