In some sense, the inode is the most interesting structure on the disk
More than any other single struct, the inode is what makes unix unix
The inode represents a file
i for index
The inodes are addressed starting with 1
Each inode's number is its i-number
The inode contains all the important information about the file:
Who owns the file? What are the permissions?
Is it a plain file, or a directory, or a symlink, or something else?
When was it last modified? When was it last accessed?
And, most important: Which data blocks hold its data?
