The Administrator has all the capabilities of a Privileged User, plus the capability to change information in the root account (such as the password) and to log in to an IRIX shell as root. Because there is only one root account, there is only one Administrator per system. The Information Panel for a particular system includes the name of the system's Administrator so other users know whom to contact for help.

On a mouse, a button is a switch that you press with a finger. In a window on your screen, a button is a labeled rectangle that you click using the cursor and mouse.
A flat metallic disk that contains information that you can view and copy onto your own hard disk; you cannot change or add to its information. CD-ROM is short for compact-disk: read-only memory.
A network where a central server controls services and information; the server is maintained by one or more individuals called network administrators. On a centralized network that uses NIS, this server is called the NIS master, and all other systems on the network are called NIS clients.

For example, when you run IRIS Showcase, the Master gizmo opens by default You can change the default settings using the Preferences gizmo.
The collection of windows and icons that appears on your computer screen. You can create multiple desks and switch between them. When you switch from one desk to another, the screen changes, almost as if you had several different monitors.

By default, several icons are placed on the desktop: a folder icon representing your home directory, a dumpster icon, several application icons, and an icon for each peripheral you have installed. You can place other icons on the desktop so that you can access them more easily.
In this way, the desktop is similar to an actual office desk. For example, on your desk, you might have a telephone, a container of pens and pencils, and a stack of folders or notebooks related to the projects on which you're currently working, Other items that are used less are stashed away in desk drawers.

You can also drag a file or application icon and place it in the drop pocket on a Directory View window. The window displays the contents of the directory in which that icon is stored.
As a final example, you can drag an IRIS Showcase icon and drop it into a drop pocket on the Search tool to specify the type of files you want to find—in this case, IRIS Showcase files.

The Primary User does not necessarily have any special access privileges; the person's name appears along with the Administrator's name in the system's Information Panel so other users know uses the system regularly. There is only one Primary User per system.
A tool that you use to set up printer software and monitor jobs that you send to the printer. You access it through either the System toolchest or the System Manager, where it is called the Printer tool.
