An inode is a data structure on a traditional Unix-style file system such as UFS or ext3. An inode stores basic information about a regular file, directory, or other file system object. Each and every file under Linux (and UNIX) has following attributes: * File type (executable, block special etc) * Permissions (read, write etc) * Owner * Group * File Size * File access, change and modification time * File deletion time * Number of links (soft/hard) * Access Control List (ACLs) All the above information is stored in an inode. So, each file has an inode associated with it and an unique number called inode number. This number is used to look up an entry in the inode table.
Data structures that contain information about files in Unix file systems that are created when a file system is created. Each file has an inode and is identified by an inode number (i-number) in the file system where it resides. inodes provide important information on files such as user and group ownership, access mode (read, write, execute permissions) and type
In Unix-like operating systems, an inode (index node) is a data structure used to represent a file or a directory on a filesystem. Each inode contains metadata about a file, such as its size, ownership, permissions, and timestamps, but does not store the filename or its actual data. The term "icore" is less common, but it may refer to the core aspects of an inode's functionality or its role in managing file data within the filesystem. Essentially, inodes are crucial for the organization and access of files on Unix systems.
In native filesystems, the inode stores:the owner (userid and groupid)file typeaccess permissionsfile access times (datetime file modified, accessed; datetime inode modified)number of links to the filetable of disk addresses for the blocks used by the data of the filefile sizeDirectories are special files which contains a mapping linking names to an inode.In many filesystems, short data can be stored in the directory.
An inode is a data structure in a Unix-style file system that stores information about a file or directory, such as its permissions, ownership, size, and location on the disk. It also contains pointers to the actual data blocks of the file. Each file on the system is represented by an inode.
what are similarities and differences between linux and unix?
Solaris is a Unix system.
In computing, an inode (index node) is a data structure found in many Unix file systems. Each inode stores all the information about a file system object (file, directory, device node, socket, pipe, etc.), except data content and file name.The reason for designating these as "i" nodes is unknown. When asked, Unix pioneer Dennis Ritchie replied:In truth, I don't know either. It was just a term that we started to use. "Index" is my best guess, because of the slightly unusual file system structure that stored the access information of files as a flat array on the disk, with all the hierarchical directory information living aside from this. Thus the i-number is an index in this array, the i-node is the selected element of the array. (The "i-" notation was used in the 1st edition manual; its hyphen was gradually dropped.)

No difference, really. Unix is an OS (Operating System)
Unix is an operating system, Java is a language.
