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
what does the audio subsystem consist of?
sounds card, the expansions bus used, audio ports, connectivity in the form of internal and external audio cables, speakers, sound card drivers, and any additional third party audio software.
what does a tv tuner card do?
turn your computer into a television. A port on the card receives input from a TV cable and lets you view television on your computer monitor
what does a video capture card do?
capture this video input and save it to a file on your hard drive
what are the 3 steps for when installing a TV tuner or capture card
Install drivers
- Install the card
- Install the application software that come with the card.
what do Communications adapters do?
ive a computer the
ability to transmit information to other devices
that might be too distant to cable up to directly.
what are the two most popular types of communications adapters?
Network adapters and modems
