Step-by-step explanation:
The process that Brandon is performing is called logging into the root account of the Ubuntu Server. The root account is a powerful user account with administrative privileges, and logging into this account allows Brandon to perform actions that require elevated permissions.
This process is also referred to as becoming a superuser or assuming root privileges. By logging into the root account, Brandon can create a new user account and make other system-level changes.
