What is Administrator

Administrator (in computer networking) is generally, a person who has full rights and permissions to all resources on a network.

The administrator is usually responsible for installing, managing, and controlling servers and networking components. Administrators can also modify the properties of user accounts and the membership of groups, create and manage security printers, install printers, share resources, and assign permissions to those resources.

In Microsoft Windows Server, the Administrator account is a built-in account whose password is defined during installation.
