inode
An inode (index node) is a data structure in a Unix-style file system that describes a file-system object such as a file or a directory. Each inode stores the attributes and disk block locations of the object’s data.1 File-system object attributes may include metadata (times of last change,2 access, modification), as well as owner and permission data.3
A directory is a list of inodes with their assigned names. The list includes an entry for itself, its parent, and each of its children.
