Question 1

What is texture

Answer 1

A small picture that is tiled over and over again to create

the 3D world

Question 2

Answer 3

1. upping the width of the bus between the video RAM
   and processor
2. specialized super-fast RAM
3. adding more RAM

Question 4

WRAM
SGRAM

Answer 4

VRAM: Video RAM– the original graphics ram
WRAM: Window RAM– designed to replace VRAM never
caught on
SGRAM: Synchronous Graphics RAM – A version of
SDRAM with features to speed up access
for graphics

Question 5

What is the name and purpose of the following Video
RAM Technologies
DDR SDRAM
DDR2 SDRAM

Answer 5

DDR SDRAM: Double Data Rate Synchronous DRAM–
used on budget graphics cards and very
common on laptop video cards
DDR2 SDRAM: Double Data Rate version2 Synchronous
DRAM– popular on video cards until
GDDR3; lower voltage then DDR memory

Question 6

What is the name and purpose of the following Video
RAM Technologies
GDDR3 SDRAM
GDDR4 SDRAM

Answer 6

GDDR3 SDRAM: Graphic Double Data Rate, version 3
Similar to DDR2 but runs at faster
speeds; different cooling requirements
GDDR4 SDRAM: Graphic Double Data Rate, version 4
Upgrade of GDDR3, faster clock

Question 7

what two issues you need to watch out for when

installing the video card

Answer 7

long cards and the proximity of the nearest PCI card

Question 8

What is the general rule for installing video drivers

Answer 8

Always uninstall the old card drivers before installing the

drivers for a new card or updating the drivers

Question 9

What is a sprites in the world of 3D gaming

Answer 9

nothing more than a bitmapped graphic file

Question 10

what are the group of points in a 3D graphic called and how does the computer user them

Answer 10

Verticles:
1. the computer must track of the verticles on the x, y
and z access.
2. then it must begin to fill each vertices with lines into
many triangles
3. Then groups the triangles into shapes called
polygons
4. then the texturing was done.

Question 11

What is the GPU and what is it used for

Answer 11

Graphical processing units: helped the CPU but taking

over some/all the 3D rendering duties
