lesson 6 Flashcards
An expansion card is
circuit board you install into a computer that improves its capabilities
the card installed must match the
the bus type of the mother board
categories of expansion cards
video, multimedia, I.O, communications
what is video adapater
expansion card that allows the computer to display info on the monitor
video card responsible for
converting the data sent by the CPU into pixels, addresses, and other items
what kind of expansion buses do video cards use?
PCI, AGP, and PCIe. PCIe is most common
what is a video cards designated processor?
Graphics processing unit - GPU), and built in ram (GDDR)
What to consider when buying a video card
amount of memory, the connectors it offers,expansion bus that the card fits into, an expansion slot available for it on the motherboard,can it
fit in the case, does the case have enough power to support/cool it
what does the video subsystem include?
video card (or integrated video), the card’s expansion bus, internal connections, external connections between the video card and the display, the display itself, and the video driver
what does VGA stand for?
Video Graphics Array
describe the VGA
15 pin, usually blue, known as
DE15F. Used for older monitors
that display VGA, SVGA, and
XGA resolution.
what does dvi stand for?
Digital Visual Interface
describe dvi
High quality, used with LCD
displays, carries uncompressed
digital video, is partially compatible
with HDMI.
what are the different types of dvi
DVI-D - Digital Only connections -DVI-A - Analog only -DVI-I - Digital and Analog -DVI-DL - Dual Link (dual link versions of DVI-I & DVI-D) M1-DA: Digital, analog, and USB
what does hdmi stand for?
High Definition Multimedia Interface
describe hdmi
Carry video and audio signals.
Some video cards do not offer HDMI but instead offer
DVI:type A - Supports all HD modes, compatible with DVI-D connectors - Type B - Double video bandwidth, supports higher resolution - Type C - Mini-HDMI, used in portable devices - Type D - Micro-HDMI, smallest HDMI connector.
describe display port
Designed to be replacement for HDMI
and DVI. Uses packet transmissions
similar to Ethernet, connector looks
similar to USB. Not as common.
what does s-video stand for?
separate video
describe s-video
Used for standard definition video, no
audio signal. Uses a mini DIN 4-,6-,7 or 9
pin connector.
describe component/ RGB
Used to send an analog or digital signal over three wires: red, green, and blue, each wire ending with an RGB plug. Sometimes used by older gaming systems.
what is the sound card responsible for?
generating sound from the data sent to it by either the operating system, or in older systems, by the CD-ROM drive
what can audio devices be integrated into?
motherboard, installed to PCI and PCIe slots, and can be
connected to USB and IEEE 1394 ports
where does a typical sound card get installed?
a slot on the motherboard.
who defines the color scheme for sound cards?
defined by the PC System Design Guide,
version PC 99
