Special video RAM designed to improve 3-D graphics simulation.
type of video display that amplifies the signal at every intersection in the grid of electrodes, which enhances the pixel quality over that of a dual-scan passive matrix display.
A mouse that plugs into a bus adapter card and has a round, 9-pin mini-DIN connector.
A condition in which chips loosen because of thermal changes.
Another term for Direct Rambus DRAM.
The hardware, usually a dial-up modem, that provides the connection between a data terminal and a communications line. See also DTE.
LCD technology divides a screen into two sections, which are refreshed simultaneously.
Both the computer and a remote terminal or other computer to which it is attached. See also DCE.
A bidirectional parallel port mode that uses a DMA channel to speed up data flow.
A parallel port that allows data to flow in both directions (bidirectional port) and is faster than original parallel ports on PCs that allowed communication only in one direction.
Common term for IEEE 1394.
A desktop monitor that uses an LCD panel.
A type of video card that has an on-board processor that can substantially increase speed and boost graphical and video performance.
Types of DDR, DDR2, and DDR3 memory specifically designed to be used in graphics cards.
A device that can be plugged into a computer while it is turned on and the computer will sense the device and configure it without rebooting, or the device can be removed without an OS error.
A network device or box that provides a central location to connect cables.
Another term for IEEE 1394.
An older card that can contain serial, parallel, and game ports and floppy drive and IDE connectors.
A standard for parallel ports and cables developed by the Institute for Electrical and Electronics Engineers and supported by many hardware manufacturers.
Standards for an expansion bus that can also be configured to work as a local bus. It is expected to replace the SCSI bus, providing an easy method to install and configure fast I/O devices. Also called FireWire and i.Link.
A standard, developed by the 1394 Trade Association, that is designed for peer-to-peer data transmission and allows imaging devices to send images and photos directly to printers without involving a computer.
wireless transceiver that uses infrared technology to support some wireless devices such as keyboards, mice, and printers. A motherboard might have an embedded infrared transceiver, or the transceiver might plug into a USB or serial port. The technol
A type of display in which the electronic beam of a monitor draws every other line with each pass, which lessens the overall effect of a lower refresh rate.
Another term for an infrared transceiver.
A method used by IEEE 1394 to transfer data continuously without breaks.
a thin, flat monitor based on a technology that manipulates liquid crystals.
Another term for a PS/2 mouse.
A type of video memory that is faster than VRAM and WRAM, but can be more economical because it can be installed on a video card in smaller increments.
A type of display in which the electronic beam of a monitor draws every line on the screen with each pass.
A cable that allows two data terminal equipment (DTE) devices to communicate in which the transmit and receive wires are cross-connected and no modems are necessary.
A type of video display technology less expensive than active matrix display.
A small spot on a fine horizontal scan line. Pixels are illuminated to create an image on the monitor.
A mouse that plugs into a round mouse PS/2 port on the motherboard. Sometimes called a motherboard mouse.
The process of periodically rewriting data, such as on dynamic RAM.
The number of pixels on a monitor screen that are addressable by software (example: 1024 x 768 pixels).
A mouse that uses a serial port and has a female 9-pin DB-9 connector.
Memory designed especially for video card processing that can synchronize itself with the CPU bus clock.
Used in LCD monitors to rapidly switch pixels on and off.
An input device that uses a monitor or LCD panel as a backdrop for user options. Touch screens can be embedded in a monitor or LCD panel or installed as an add-on device.
Three dots of color that make up one composite dot on a CRT screen.
A chip that controls serial ports. It sets protocol and converts parallel data bits received from the system bus into serial bits.
Manages the USB bus. If the motherboard contains on-board USB ports, the USB host controller is part of the chipset. The USB controller uses only a single set of resources for all devices on the bus.
RAM on video cards that holds the data that is being passed from the computer to the monitor and can be accessed by two devices simultaneously. Higher resolutions often require more video memory.
Dual ported video RAM that is faster and less expensive than VRAM. It has its own internal bus on the chip, with a data path that is 256 bits wide.
