Answers

1. A, B, D. Currently, video cards use the following bus types: PCI, AGP, and the newer PCI Express.
2. A, C, D. Cooling can be provided through passive heat sinks or through cooling fans and fan shrouds. Passive heat sinks on older video cards typically cover only the graphics processing unit (GPU), but newer ones provide cooling for both the GPU and memory. Video cards with passive heat sinks are good choices for home theater PCs, such as those running Windows XP Media Center Edition, because these PCs need to run as quietly as possible. The material used to transfer heat between heat sinks and cooling fans is known as thermal paste or phase-change material, not thermal glue.
3. A, B, D. With the addition of the plug and play BIOS, most of the time you will be able to skip the BIOS configuration. But some cards might not be recognized and you must configure the BIOS manually.
4. B. Without the device driver installed, you will not be able to use all the features that come with it. Most of the time you get an install disk when you purchase a new card.
5. A, B, C. The three main types of display devices in use today are LCD monitors (the most common), CRT monitors, and data projectors.
6. A, B, C. VGA, DMI, and HDMI are the three main types of connectors you will be dealing with. You can also use S-Video for a connection.
7. C. The DVI port is the current standard for digital LCD monitors. The DVI port comes in two forms: DVI-D supports only digital signals and is found on digital LCD displays. DVI-I provides both digital and analog output and supports the use of a VGA/DVI-I adapter for use with analog displays.
8. B. Right-clicking on the desktop and selecting Properties opens the Display Properties window. Select the Settings tab to modify the display resolution.
9. A. The three steps listed are all ways to install a monitor; however if you have a monitor that your video card does not support, you must either get another cable or a new video card that supports the cable you have.
10. C. Most of the time if you see the colors flickering on the monitor, you can turn off the monitor and the system, tighten the cable, and restart the computer.
11. D. When installing a new monitor it might not accept the current settings, so using the buttons on the front of the monitor, you can adjust your picture size.
12. A, B, C, D, E, F. It is recommended that you use all of the solutions listed to help prevent problems with your monitor as well as with you video card.
