What is an inode and what information does it contain?
What will be an ideal response?
Partitions containing directories and files in the ufs and ext file systems are built on the concept of information nodes, or inodes. Each directory or file has an inode and is identified by an inode number. Inode 0 contains the root of the directory structure (/) and is the jumping-off point for all other inodes.
An inode contains (1) the name of a directory or file, (2) general information about that directory/file, and (3) information (a pointer) about how to locate the directory/file on a disk partition. In terms of general information, each inode indicates the user and group ownership, the access mode (read, write, and execute security permissions, discussed later in this chapter), the size and type of the file, the date the file was created, and the date the file was last modified and read.
