Briefly describe the concept of inodes used in native Linux file systems.

What will be an ideal response?

Each file has an inode and is identified by an inode number. Inode 0 contains the root of the folder structure (/) and is the jumping-off point for all other inodes. An inode contains general information about that file. Each inode indicates user and group ownership, access mode, the size and type of the file, the date the file was created, and the date the file was last modified and read. The inode for a file contains a pointer (number) that tells the operating system how to locate the first in a set of one or more logical blocks that contain the specific file contents (or it specifics the number of blocks or links to the first block used by the folder or file). In short, the inode tells the operating system where to find a file on the hard disk.
