• Troubleshoot expansion card problems

2. What first name or nickname would you like us to use?

You may optionally provide this to label your report, leaderboard, or certificate.

2. When installing an expansion card, which of these should you do?

Make sure the computer is plugged into the AC wall outlet.

Hold the card only by its slot connectors.

Use firm but not excessive force to snap the card into the slot.

Avoid letting the metal flange touch the PC case.

After handling the card only by the edges and avoiding the slot
connectors, you should snap it into an open slot on an unplugged system, pushing firmly and evenly until the metal flange is in contact with the slot on the case.

3. Which variation of the PCI bus was specifically designed for laptops?

PCI-X

PCIe

Mini-PCI

AGP

The Mini-PCI format conserves space and power, making it an ideal card type for use in laptops.

Explanation

The Mini-PCI format conserves space and power, making it an ideal card type for use in laptops.

4. How does the CPU communicate with a device?

It uses the device’s I/O addresses over the address bus.

It uses the device’s IRQ addresses over the data bus.

It uses the device’s COM port over the address bus.

It uses the device’s DMA over the data bus.

The CPU uses the device’s I/O addresses over the address bus to communicate with that device.

Explanation

The CPU uses the device’s I/O addresses over the address bus to communicate with that device.

5. Which of these devices is likely to still use DMA?

USB flash drive

Floppy drive

Hard drive

CD-ROM drive

On most modern PCs, only the floppy drive (if one is installed!) still uses classic DMA.

Explanation

On most modern PCs, only the floppy drive (if one is installed!) still uses classic DMA.

6. Which of the following statements best describes the hexadecimal numbering
system?

It is a binary numbering system that uses only two digits, a 0 and a 1.

It is another name for the decimal numbering system with ten digits, 0through 9.

It is an eight-digit numbering system, using letters A through H.

It is a sixteen-digit numbering system that can express all its values byusing four wires.

The hexadecimal numbering system represents binary values using the characters 0–9 and A–F.

Explanation

The hexadecimal numbering system represents binary values using the characters 0–9 and A–F.

7. What does a red “X” next to a device in Device Manager indicate?

A compatible driver has been installed that may not provide all thefunctions for the device.

The device is missing or Windows cannot recognize it.

The system resources have been assigned manually.

The device has been disabled because it is damaged or has a systemresource conflict.

The dreaded red “X” can mean a bad connection, a bad driver, or even a bad card.

Explanation

The dreaded red “X” can mean a bad connection, a bad driver, or even a bad card.

I/O address 378 and IRQ7

I/O address 3F8 and IRQ4

I/O address 278 and IRQ5

I/O address 2F8 and IRQ5

The LPT2 port is by default assigned I/O base address 278 and IRQ5.

Explanation

The LPT2 port is by default assigned I/O base address 278 and IRQ5.

9. Which of the following statements about the expansion bus is true?

The expansion bus runs at the speed of the system clock.

The expansion bus crystal sets the speed for the expansion bus.

The CPU communicates with RAM via the expansion bus.

The frontside bus is another name for the expansion bus.

A separate expansion bus crystal enables the expansion bus to run at a different speed than the frontside bus.

Explanation

A separate expansion bus crystal enables the expansion bus to run at a different speed than the frontside bus.
