Explanation

In Unix/Linux systems, the root user has both UID (User ID) and GID (Group ID) set to 0. This is a fundamental system convention - the value 0 uniquely identifies the superuser with unrestricted privileges. Other user and group IDs start from 1 upwards for regular users and system accounts.
