Unmount and mount system calls
Write down a short note on unmount and mount system calls.
Expert
The privileged mount system call is employed to affix a file system to a directory of any other file system; the unmount system call separates a file system. When you mount any other file system on to your directory, you are basically splicing one directory tree onto a branch in any other directory tree. The primary argument to mount call is the mount point, i.e., a directory in the present file naming system. The subsequent argument is the file system to mount to that point. In UNIX system's drive when you insert a cdrom, the file system automatically mounts the cdrom to ‘/dev/cdrom’ in your system.
