The UNIX disk object that represents the existence of a file. The inode records owner and group IDs Fstype Date & time last access last modification n/o links size of file addresses of blocks where the file is physically present and permissions
The inode is the focus of all file activity in the file system. There is a unique inode allocated for each active file each current directory each mounted-on file text file and the root. An inode is named by its device/i-number pair.
You can check the inode number of a file by typing ls -li
To add to the definition when you create a hard link it is actually another file gets created with the same inode number. so in a way there is only one inode number which is associated with two file names having diffrent locations on the disk but acutually refering to the same file. In this case when you call a delete (rm) on one of hte files you are actually not deleting the file indeed you are deleting a reference to the file.
Hi Inode which is to describe the file's starting address. It's managed by the linux OS. Each file has its own inode number (you can remember it as a file pointer by OS as in C terms).
A unique number associated with each filename. This number is used to look up an entry in the inode table which gives information on the type size and location of the file and the userid of the owner of the file.

an inode is a data structure on a traditional Unix-style file system such as UFS. An inode stores basic information about a regular file directory or other file system object
