An inode ( eye-node) is a datastructure on the disk the describes and
stores a files attributes, including its location.

The information on a file (ownership, permissions, location on disk)
cannot be kept in the file. It must be kept somewhere else. Somewhere else
is the Inode.

The super block is a block on the disk where critical system information
is kept.  It is so important that your install will create many duplicates
just in case every 8192 blocks.  The system will not work if your
superblocks become corrupted.
