Question - What is the role of the superuser? 
          
        
        Answer - 
        
There are basically three types of accounts in the Unix operating system:
- Root account
 - System accounts
 - User accounts
 
‘Root account’ is basically referred to as a ‘Superuser’. This user has completely open access or say control on all files and commands on a system. This user can also be assumed as a system administrator and thus has the ability to run any command without any restriction. It is protected by the root password.
