Determine if the statement is true or false. If false, correct the statement.
One of the main components on the video card is the graphics processor, or GPU. It assists the CPU, and has special instruction sets for manipulating graphics data.
Definition
True
Term
Circle the correct answer.
The GPU operates at a lower / higher clock frequency than the CPU because it is
dedicated to graphics and repeatedly processes a limited set of graphics-related instructions.
Definition
lower
Term
List the three main types of graphics processors.
Definition
Fram buffer, graphic accelerator, graphic coprocessors.
Term
This type of GPU is most often found on consumer-grade graphics cards. The system’s CPU instructs this processor to compute graphics-intensive calculations.
Definition
Graphics accelerator
Term
This type of GPU is most often found on professional-grade graphics cards. It processes all graphics-related data, and consequently frees up the CPU’s resources for performing other tasks.
Definition
Graphics coprocessor
Term
Determine if the statement is true or false. If false, correct the statement.
The memory on a video card can store multiple Bytes of information per pixel, thus, the more onboard memory available, the higher the quality of the video card.
Definition
True
Term
This type of RAM is most commonly included in today’s video cards.
Definition
DDR SDRAM
Term
Circle the correct answer.
A CLUT / true-color card will allocate three to four Bytes-worth of information per pixel, thus requiring more memory than other types of video cards.
Definition
true color
Term
This color system is used by some graphics cards to assign one Byte of information to each pixel. These Bytes are then referenced to look up the associated color value in a pre-defined chart.
Definition
CLUT
Term
This ROM chip is activated shortly after the computer has been powered on. It ensures that the video card is recognized by the system, and that it is primed to send important startup graphics information to the monitor.
Definition
Graphics BIOS
Term
The digital-to-analog converter on a video card is referred to as this because it directly converts information from memory into an analog signal.
Definition
RAMDAC
Term
This DB-15, VGA connector for CRT monitors sends a/n __________ color output to the monitor.
Definition
analog
Term
This display connector keeps the output signal digital.
Definition
DVI
Term
This common interface for video card installation offers a dedicated I/O connector.
Definition
AGP
Term
This is currently the fastest AGP standard.
Definition
AGP 8x
Term
Determine if the statement is true or false. If false, correct the statement.
The PCI Express I/O bus system replaces the current AGP video card interface standard.
Definition
True
Term
These small software programs synchronize video cards with current hardware, operating systems, and application requirements, and can be updated as necessary.
Definition
Video drivers
Term
These routines and protocols establish a foundation for building software. They help applications run smoothly across multiple platforms, and ensure comparable functioning across computers using different hardware and running various operating systems.
Definition
Application program interfaces
Term
This powerful API is used for producing quality, integrated software for Windows-based computers.
Definition
DirectX
Term
This reliable API is an open, vendor-neutral graphics standard that is currently an integral component of Apple OS X.
Definition
OpenGL
Term
These two companies manufacture nearly all of the graphics accelerators used in consumer-grade graphics cards.
Definition
NVIDIA & ATI
Term
Circle the correct answer.
A professional / consumer video card is designed for enhancing video playback, gaming, and user interactions with GUI-based applications.
Definition

Term
Circle the correct answer.
A professional / consumer video card is designed for the purposes of professional
animation. It offers powerful tools for the rendering of complex 3-D graphics.
Definition
Professional
Term
This type of video card provides some elements of both professional and consumer video cards at a reasonable price.
Definition
Pro-sumer
Term
In this type of monitor, a ray gun in a vacuum tube shoots a beam of electrons which charge colored phosphor dots on the screen.

Term
Determine if the statement is true or false. If false, correct the statement.
A field replacement unit (FRU) is designed to be repaired in the field upon breaking.
Definition
False
Term
Determine if the statement is true or false. If false, correct the statement.
The electrodes and capacitors in a CRT monitor can cause a lethal electrical shock, therefore these units are best left unopened and simply replaced when broken.
Definition
True
Term
This type of CRT monitor has a flat screen that reduces glare, and uses thin metal wires for filtering stray electrons, thus generating very sharp images.
