Answer 2

The correct answer is mode number  

Explanation:  

Every file in a computer is a long string of zeros and ones. A file is considered as a finite length series of bytes. Here, every single byte is an integer between a number 0 and 255. As a result, a computer system can find a file by its mode number. Thus, the mode number recognizes a file in the file system.
