ext2 and inode overview

1. Ext2 is based on inodes, ie, it makes a separate management structure known as an inode available on disk for each file.

2. The inode contains not only all meta-information but also pointers to the associated date blocks.

3. Hierarchical structures are set up by representing directories as regular files whose data section includes pointers to the inodes of all files contained in the directory.
