What is inode explain?
An inode is a data structure in UNIX operating systems that contains important information pertaining to files within a file system. When a file system is created in UNIX, a set amount of inodes is created, as well. Usually, about 1 percent of the total file system disk space is allocated to the inode table.
What is inode explain with example?
Inode Basics An Inode is a data structure that stores the following information about a file : Group ID of the file. The file mode information and access privileges for owner, group and others. File protection flags. The timestamps for file creation, modification etc.
Why do we use inode?
Data is stored on your disk in the form of fixed-size blocks. If you save a file that exceeds a standard block, your computer will find the next available segment on which to store the rest of your file. Over time, that can get super confusing. That’s where inodes come in.
Why inode is so important in Linux?

File names & directories File names and directory implications: inodes do not contain file names, only other file metadata. Unix directories are lists of association structures, each of which contains one filename and one inode number.
