Which of the following statements are true regarding buffered memory modules? (Choose two)
They increase the electrical load placed on the controller
They decrease the electrical load placed on the controller
When used, the memory controller communications in series with the register
When used, the memory controller communications in parallel with the memory chips
They decrease the electrical load placed on the controller
When used, the memory controller communications in series with the register
Buffered memory modules include specialized chips that act as buffers for signals from the memory controller. By buffering these signals, the electrical load placed on the controller is reduced because the memory controller communicates in series with the register, instead of in parallel with the memory chips. The register performs the parallel communication with the chips
You have a desktop computer that is about five years old, with a single-channel memory architecture. You want to upgrade the memory. After checking the documentation, you purchase a higher-capacity RAM module that runs at the required bus speed. After you install it, the new RAM is not recognized but the old RAM is. The computer store tests the RAM and it’s fine. What should you try next?
Flash the BIOS
Return the memory module and purchase a lower-capacity one
Replace the motherboard
Flash the BIOS
That capacity of module might not have been in existence when the motherboard’s chipset was released. Sometimes flashing the BIOS is all that is required

The set of signal pathways on a motherboard between the CPU and RAM is called what?
Southbridge
Frontside bus
Backside bus
Frontside bus
The communications between the CPU and memory occur over what is known as the frontside bus (FSB), which is just a set of signal pathways connecting the CPU and main memory
One of your users needs to print several copies of a 20-page document. She wants to ensure that all the pages print in order so she doesn’t have to reorganize the documents later. Which option does she need to set properly in her printer configuration settings?
Duplex
Collate
Orientation
Collate
The user wants to make sure that the collate option is set properly. It will let her select whether she wants it to print pages in order (1, 2, 3… 1, 2, 3… and so on) or multiple copies of the same page at once (1, 1, 1… 2, 2, 2… and so forth). Other options you can often set up in the printer configuration settings are duplexing (printing on the front and back), orientation (portrait or landscape), and print quality (such as draft or high resolution)
Which of the following video resolutions is compatible with the 4.3 aspect ratio?
UXGA 1600x1200
ATSC 1920x1080
WUXGA 1920x1200
UXGA 1600x1200
The term aspect ratio refers to the relationship between the horizontal and vertical pixel counts that a monitor can display. For example, for a display that supports 4:3 ratios, such as 1600×1200, if you divide the first number by 4 and multiply the result by 3, the product is equal to the second number. Additionally, if you divide the first number by the second number, the result is approximately 1.3, the same as 4 ÷ 3
