Why do all files have the same inode number?
Each file in a filesystem has a unique inode number. Inode numbers are guaranteed to be unique only within a filesystem (i.e., the same inode numbers may be used by different filesystems, which is the reason that hard links may not cross filesystem boundaries). Not the answer you’re looking for?

Which is an example of a root inode?
One example you’ll run into quickly is the root inode on ext2/3/4 file systems, which is 2: on a system with multiple file systems you’ll see many, many duplicate inode numbers (although you need to take the output with a pinch of salt since it will also include hard links).
How is the length of a number sequence determined?
In mathematics, a sequence is an ordered list of objects. Accordingly, a number sequence is an ordered list of numbers that follow a particular pattern. Each of the individual elements in a sequence are often referred to as terms, and the number of terms in a sequence is called its length, which can be infinite.
How to find two files with the same Dev number?
If two directory entries have the same inode and dev number, they refer to the same file (though possibly through two different mounts of a same file system for bind mounts). Some find implementations also have a -samefile predicate that will find files with the same device and inode number.
How to point diff file to two different directories?
If it’s GNU diff then you should just be able to point it at the two directories and use the -r option. N.B. As pointed out by Dennis in the comments section, you don’t actually need to do the command substitution on the ls.
How are inodes unique on a partition level?
Inodes are only unique on a partition level, not on the whole system. On each partition, there is a superblock. This superblock tells the system which inodes are used, which are free, etc (I’ll spare you the technical details).
Is there a way to compare two folders?
Once you enter this command—changing folder-1 and folder-2 to the folders you want to compare, of course—the terminal will spit out a list of differences between them. That’s all there is to it!
