ANS: The X Window System allows graphical applications to be displayed and operated on any monitor,without running the applications on the machines to which these monitors are connected. The basis for this is the separation into a server component (X server) and the application itself (client application). The X server and client application communicate with each other by way of various communication channels. X server The X server controls the graphical screen. This corresponds roughly to what would be called a graphics driver on other systems. In addition, it manages the input devices, such as keyboard and mouse, and transmits their actions to the X client. The X server, however, has nothing to do with the appearance of the window and the desktop; this is the task of the window manager. XFree86 and X.org are free implementations of the X server. SUSE Linux Enterprise Server 10 defaults to using X.org. Client application The client application is a graphical application that uses the services of the X server to receive keyboard and mouse actions and to have its own output displayed on the screen. 42. ANS: Window managers are specialized client applications. A window manager works together with the X server and provides additional functionality. The window manager * Provides control elements * Manages virtual desktops * Provides functionality of window frames (for example, changing their size)

6 43. ANS: The right frame of the main menu displays six system options: * Help Starts the online help. * Control Center Starts the GNOME Control Center where you can configure your desktop. * Install Software Shows a list with the available software on your registered installation media. * Lock Screen Locks the screen. Enter your password to unlock the screen. * Logout Logs you out of the system. * Shutdown Shuts down or reboots the system. PTS: 1 REF: ANS: The information asked include: * Name Enter the name and label of the launcher. * Generic name (Optional) Enter a generic name. * Comment (Optional) Enter a comment that will appear as a Tooltip when moving the mouse pointer over the icon. * Command Specify a command that should be executed when double-clicking the launcher icon. * Type Create launchers for different file types (e.g., application, directory, link, device). * Icon (Optional) Select an icon for the launcher. * Run in terminal Select this option if the application does not have a graphical user interface and runs in a terminal window. PTS: 1 REF: ANS: You can add new programs to the bottom panel by right-clicking a free area of the panel and then selecting Add to Panel. From the dialog that appears select the application you want to add. You can remove a program from the control panel by right-clicking its icon in the bottom panel and then selecting Remove From Panel. You can move icons in the panel by holding down the right mouse button and selecting Move from the Context menu. PTS: 1 REF: ANS: You can add icons to the list of favorite applications by doing the following: 1. Open the main menu in the panel. The menu appears. 2. Select More Applications. 3. Using the right mouse button, select an application item in the right frame. 4. Select Add to Favorites from the pop-up menu. PTS: 1 REF: ANS: GNOME provides its own file manager (called Nautilus). You can start Nautilus by selecting the username s Home icon on the desktop or by selecting Nautilus from the main menu. By default Nautilus is marked as a favorite application. Normally Nautilus shows the content of the user s home directory after starting. The right frame of the Nautilus window shows the content of the current directory. You can see your current position in the location bar below the toolbar. All higher directories are shown as buttons. Select one of these buttons to change to the higher directory. PTS: 1 REF: 55-56

7 48. ANS: A menu at the top of the side panel allows you to select the content of the side panel: * Places Shows the most important directories and devices to store files. * Information Shows some information about the current directory. * Tree Shows the file system tree and the tree of the home directory. * History Shows a history of the last visited directories. * Notes Allows you to enter notes for the current directory. * Emblems Shows the list of emblems. PTS: 1 REF: ANS: A classic multiuser environment can be implemented by connecting several terminals (dialog stations) monitor and keyboard units to the serial interface of a single computer. Linux also supports multiuser environments, allowing you to connect several terminals to the serial interfaces of a Linux system. PTS: 1 REF: ANS: Serial terminals are rarely used; instead, virtual terminals were created in Linux. With virtual terminals, you can work in Linux as if you had several classic serial terminals available at the same time. You can have up to six virtual terminals (F1-F6) running on your computer. By pressing Ctrl+Alt+Fx, you can switch between individual terminals. By pressing Ctrl+Alt+F7, you can switch back to your graphical user interface. You can determine the terminal currently being used from the tty number (tty1 tty6). tty is an abbreviation for teletype, which is another word for terminal. PTS: 1 REF: 58
