Aspect ratio refers to the proportion, or ratio, between a window's width and height. If you want to maintain the relative proportion between the window's width and height when you change the size of a window, set the aspect ratio setting to ON. Then, when you change a window size, the aspect ratio is automatically adjusted to preserve the aspect ratio. If this setting is OFF, you can resize the window to any size and the aspect ratio is not maintained. Aspect ratio is a window sizing attribute.
A small display box that has a raised appearance and contains text. Generally, clicking on a button activates a function or performs some action. See Clicking.
An application program that connects to the server. A client program performs a variety of tasks, including window management.
A term that describes the saturation or vividness of a color. A chroma of 0 describes a neutral, gray color. Chroma ranges to the most vivid color a screen or printer generates for a specific hue and value. See Hue and Value.
Consists of a set of entries defining color values. A pixel value indexes into the colormap thereby producing intensities of red, green, and blue which are visible on a display.
The line that you type to invoke a program or initiate an action. A command-line usually contains the name of an X client or application program, along with optional arguments known as command-line options.
A user-level protocol which is part of the DECnet Protocol set. Cterm provides a Network Virtual Terminal, which allows you to log in to a remote host on the network as if you are using a terminal directly attached to the remote host.

A device that receives video output from the logic module and displays the video output on a screen.
The factory-defined hardware address of the network computer. Network hardware uses the Ethernet address when communicating to the network. This address is on the serial number label on the back of the logic module. You can also display the Ethernet address by viewing the TCP/IP Configuration Summary Menu in Setup.
In the X Window System, information sent by the X server to an X client, for example, notification to the client that you pressed a mouse button.
Software instructions that are permanently stored in the memory of a computer and are not lost when you turn the power off. Also called NVRAM.
A computer device that controls the exchange of data between itself and another network computer. Network computers typically boot from a host.
A term that describes a color family (for example, red or yellow). Hue is a polar coordinate--that is, it moves in a circular motion around the color spectrum--and ranges from 0º to 360º, with 0º being red. Hue is measured in degrees. See Chroma and Value.
A box on the screen that lets you enter a color index--an integer used to label a particular color--from the keyboard.
A device that allows you to send information to a window. Typical input devices include keyboards, mice, tablets, and trackballs. See Pointer and Pointing Device.
A common connection that is used for sending or accepting information and control between programs and machines.
A system administrator-assigned address for the network computer. This address is used under TCP/IP when the network software of the network computer generates messages to another host. The IP address is in the form nnn.nnn.nnn.nnn where nnn is a decimal number in the range 0 to 255. You can display the IP address by viewing the Network Configuration Summary Menu in Setup.
The network layer protocol for the Internet Protocol Suite. Internet Protocol is responsible for addressing and routing packets between hosts.
The linking together of terminals, network computers, and computers via cables and microwave links. This allows you to access more than one computer.
A device that gets data from a host, a keyboard, or a peripheral, and processes it for viewing on the display. The logic module runs the X server and local clients. It can be a separate unit or integrated into the base of the monitor.
A list of commands or functions that you select with a pointer. A menu is normally displayed in a small window.
An input device that, when moved across a flat surface, causes the pointer to move across a screen. The mouse usually has buttons that you press to send signals. These signals, in turn, accomplish certain functions. The representation of the mouse on the screen is called the pointer. See Pointer.
The physical wires connecting two or more computers. These connections allow information to move electronically between computers.
A computer that displays information which usually resides on another computer. A network computer consists of a display, a keyboard, a mouse or other pointing device, a logic module, an X server, and local clients. See Display, Logic Module, Mouse, Pointer, and X Server.
A device used to input or output data for the network computer. The XPT/A graphics tablet is a supported peripheral device for network computers.
The pointer allows you to make selections in menus, to size and position windows and icons, and to select the window where you want to send the input. The window manager determines the shape of the pointer. See Pointing Device.
Typically a mouse, tablet, or some other device with effective dimensional motion. The core protocol defines only one visible cursor, which tracks whatever pointing device is attached as the pointer. See Pointer.
A physical connection (such as a multi-pin connector or coaxial connector) and its associated firmware, that permits one computing device to communicate data and control information with another computing device or peripheral device.
A set of rules that allows computers to transfer information across a network to other computers that speak different computer languages.
Special firmware in the network computer that allows it to boot without being connected to a host computer.
An additive method of combining percentages of red, green, and blue primary colors to form other colors.
The window that fills the screen during an X session. All windows opened by clients appear on top of the root window. See Stipple Pattern.
A standard communications interface defined by the Electronic Industries Association (EIA) to control data communications using standard voltages, signal lines, and device interactions.
One or more optional physical connectors on your network computer. Attach a serial cable (RS 232) to communicate with a peripheral device such as a modem or printer.
The combination of graphics display, hardware, and server software that provides display services for clients. The server also handles keyboard and mouse input. See Client and X Server.
A set of instructions that tell the computer to perform a certain task in order to obtain a specific result. See Client.
In the X Window System, the underlying pattern displayed (with the X cursor) when there are no other windows on the screen. If a window is created, the window appears on top of the stipple pattern. See Root Weave.
A user-level protocol which is part of the Internet Protocol set. Telnet provides a Network Virtual Terminal, which allows you to log in to a remote host on the network as if you are using a terminal directly attached to the remote host.
A window showing a list of host computer names and network addresses. Use the mouse to select a computer where you have a login account.
The I-shaped pointer which appears in a text input area. Clicking the mouse in a text input area causes the text cursor to appear in that area. Whatever information you type on the keyboard appears in the text input area displaying the text cursor.
The Internet transport layer protocol which provides a reliable, bi-directional byte stream connection between two cooperating user-level processes.
Using the TCP and IP protocols to obtain a reliable, bi-directional byte stream connection between two cooperating user-level processes. Commonly this refers to the entire Internet Protocol suite, including TCP, IP, UDP, ICMP, and other protocols.
A protocol used for downloading server images. It is also used for reading and writing font files, the color definition file, or remote configuration files.
A term describing the lightness or darkness of a color. Value ranges from 0 (black) to 100 (white). See Chroma and Hue.
A local ICA client that allows you to access Windows NT applications using your network computer with Microsoft's Windows NT Terminal Server Edition and Citrix Metaframe server software.
In the X Window System, typically a region on the screen of a display created by an X client for displaying data. (An X client can create more than one window.) For example, the xterm terminal emulator, xfd font displayer, and the bitmap graphics editor all create windows. You can use a window manager to manipulate windows on the screen. See Window Manager.
An X client that allows you to organize and rearrange windows. The window manager controls the size and placement of windows and can also control window attributes such as border size.
A program that runs locally on a network computer and lets you use the screen of the network computer. The X server processes a request (for example, a request to create a window), collects input data, and sends information (called an event) to clients. See Event.
