98 c error messages about video appear when windows

98 C Error messages about video appear when Windows starts. This can be caused
by a conflict in onboard video and the video card. Try disabling onboard video
in Device Manager.
99 A A sound card (an expansion card with sound ports) or onboard sound (sound
ports embedded on a motherboard) can play and record sound, and then save it
in a file.
100 C A sound card (an expansion card with sound ports) or onboard sound (sound
ports embedded on a motherboard) can play and record sound, and save it in a
file.
101 B A TV tuner card can 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.
102 A A video capture card lets you capture video input and save it to a file on your
hard drive.
103 B When installing a TV tuner or capture card, you will most likely install the
drivers, install the card, and then install the application software that comes
bundled with the card. You can then configure and manage the card using the
applications.
104 C The CRT (cathode-ray tube) monitor was first used in television sets, takes up a
lot of desk space, and is now largely obsolete.
105 A The LCD (liquid crystal display) monitor, also called a flat-panel monitor, was
first used in laptops.
106 D A plasma monitor provides high contrast with better color than LCD monitors.

107 B Backlighting is used to light the LCD panel. The trend for most monitor
manufacturers is to use LED backlighting, which provides a better range and
accuracy of color and uses less power than earlier technologies.
108 A An OLED (Organic Light-emitting Diode) monitor uses a thin LED layer or
film between two grids of electrodes. OLED screens provide better contrast,
work in darker rooms, and use less power than an LCD monitor.
109 C The refresh rate, also called the response time, is the time it takes for a monitor
to build one screen, measured in ms (milliseconds) or Hz (hertz).
110 B The resolution is the number of spots or pixels on a screen that can be
addressed by software.
111 D The native resolution is the number of pixels built into the LCD monitor.
112 B Brightness is measured in cd/m2 (candela per square meter), which is the same
as lumens/m2 (lumens per square meter).
113 C A video card can use an AGP, PCI, or PCI Express slot on the motherboard.
The fastest slot to use is a PCIe x16 slot.
114 D The 15-pin VGA port is the standard analog video port and transmits three
signals of red, green, and blue (RGB).
115 B The DVI-I port supports both analog and digital signals.
116 C Composite video does not produce as sharp an image as VGA video or S-
Video.
117 A The HDMI standards allow for several types of HDMI connectors. The best
known, which is used on most computers and televisions, is the Type A 19-pin
HDMI connector.

118 D A few older video cameras use a 6-pin variation of S-Video. The connector is
called a MiniDin-6 connector and looks like a PS/2 connector used by a
keyboard or mouse.
