1. Brief about the directory representation in UNIX.
A Unix directory is a file containing a correspondence between filenames and
inodes. A directory is a special file that the kernel maintains. Only kernel
modifies directories, but processes can read directories. The contents of a
directory are a list of filename and inode number pairs. When new directories
are created, kernel makes two entries named '.' (refers to the directory itself)
and '..' (refers to parent directory). System call for creating directory is
mkdir (pathname, mode).
