The inode is a data structure in a Unix-style file system which describes a filesystem object such as a file or a directory

The inode is a data structure in a Unix-style file system which describes a filesystem object such as a file or a directory. Each inode stores the attributes and disk block location(s) of the object's data. Filesystem object attributes may include metadata (times of last change, access, modification), as well as owner and permission data.

Directories are lists of names assigned to inodes. A directory contains an entry for itself, its parent, and each of its children.
