The CMOS setup program is part of the BIOS program. The key or keys you press to open the CMOS editor depend on the BIOS manufacturer. The easiest way to fin out which key to press is to read the screen as it boots or to consult the motherboard documentation.

Explain this memory error: The system boots, but the memory count is incorrect

The POST failed to recognize all of the memory. This can happen with incompatible memory installation. Remember to avoid combining dual-bank with single-bank memory. If any problem is detected during system boot, check the BIOS settings.

Processing capabilities

The capacity of the graphics processing unit (GPU).

PCI Express (PCIe)

The connector that replaced PCI, PCI-X and AGP.

What has happened when the system boots, but the memory count is incorrect?

This can happen with incompatible memory installation. Remember to avoid combining dual-bank with single bank memory.

You need to connect a monitor that provides an HDMI port and a VGA port to a video adapter in a PC system that uses a DVI-D connector. Which of the following options would provide the BEST display quality at the lowest cost? -Purchase a new monitor with a DVI-D port. -Use an adapter to connect the monitor HDMI port to the DVI-D connector on the PC. -Use an adapter to connect the monitor VGA port to the DVI-D connector on the PC. -It's not possible to connect this monitor to this PC.

Use an adapter to connect the monitor HDMI port to the DVI-D connector on the PC.

What type of slot can a PCIe x1 expansion card be placed in?

anything bigger than it, so PCIe x1 can be placed into a PCIE x16

What are the functions of the BIOS?

controls the startup process and loads the operating system into memory.

DAC

digital to analog converter

What are the differences between integrated graphics and dedicated video cards?

integrated- cheaper, quality is not as great. shares system memory for graphic processing. dedicated- more expensive and quality is significantly better. Has a GPU and a dedicated high speed video memory bank.

What advantage does a PCle bus have over a PCI bus?

much faster and allows for a lot more functionality and features.

What is the difference between ECC and registered memory?

registered memory aka buffer memory has a buffer that holds memory addresses or data before it is transferred to the memory controller. ECC is type of memory that detects and corrects the common kinds of internal data corruption.

How does the video card affect the quality of the image on the monitor?

resolution-number of pixels displayed on screen. refresh rate- number of times in one second that the GPU draws a frame.

Why does the CMOS require a battery?

to keep the real time system clock running when the computer is powered off.
