34 Glossary - Workstation Products
CRT
Acronym for "cathode ray tube," which is the main component of computer
monitors and TVs. Color CRTs use three separate electron beams fired through a
shadow mask and onto the back of the glass screen. The electron beams activate
separate red, green, and blue values in various strengths in order to produce a
colored image.
DisplayPort
DisplayPort is a digital display standard that became a VESA-approved standard in
May 2006. HDMI™ is aimed primarily at the consumer electronic market, but
DisplayPort was designed with computer displays in mind. It is scalable and
extensible in terms of pixel depth and resolution, designed to work as a
comprehensive solution both for PCs and notebooks, which currently use different
signaling standards (DVI and LVDS). DisplayPort is designed as a long-term
comprehensive replacement for VGA, providing a cost-effective, scalable, industry
standard which will consolidate external (box-to-box) and internal (LCD panel)
display connections.
DVI
Acronym for "Digital Video Interface," a standard video connection used on many
current computer displays. There are three types of DVI connections: DVI-A
(analog), DVI-D (digital), and DVI-I (integrated, capable of either analog or digital). It
supports high-bandwidth video signals over 160 Hz, so it is most often used for high-
resolution displays.
Frame Buffer
The portion of the memory buffer on the graphics card used to store the image
being displayed. All rendering processes have been accomplished by this stage and
this buffer contains only a one-to-one relationship of the data to be relayed to the
display.
Frames Per Second
In terms of 3D graphics, refers to the rate at which the graphic processor can render
new screens per second. Higher rates equals better, more naturalistic performance
for such things as games set in a 3D environment. Sometimes abbreviated to "fps."
GPU
GPU is an acronym for "Graphics Processing Unit." The GPU powers the operations
of a graphics card including support for 2D/3D and video.
HDCP
HDCP is an acronym for "High-Bandwidth Digital Copy Protection." It is a form of
digital rights management designed to protect copyright of signals being
transported across DVI or HDMI™ connections. Several international regulatory
bodies have recommended its incorporation into high-definition display and
playback devices.
HDMI™
HDMI™ is an acronym for "High Definition Multimedia Interface." It is a 19-pin
connector used for transferring combined digital audio and video. HDMI™
supports standard, enhanced, and high-definition digital video signals, and is
designed for use with VCRs, DVD players, personal computers, and set-top boxes.
A DVI adapter can be used to transfer the video signal to an HDMI™-capable display,
although audio must be transferred from a different route, as DVI output does not
support audio.
