Answers to Review Questions
1.
B. Installing a new device driver can sometimes fi x problems or introduce minor feature
upgrades.
2.
A. Device Manager shows each device and its driver version. You can access it as a
standalone tool or as part of Computer Management, as demonstrated in Exercise 7.1.
3.
A. The lowest score among the key components determines the base score, because that
component creates a bottleneck in performance.
4.
C. Video playback problems and graphic delays may indicate that a better display adapter
is needed.
5.
B. More RAM can help run more programs at once without a performance slowdown.
6.
D. In Task Manager, the Processes tab shows the amount of RAM used by each process.
7.
B. Although processors are not particularly diffi cult to install, most motherboards accept
only a few similar processors, so dramatic system improvement cannot usually be obtained
by upgrading the processor.
8.
B. A parallel ATA drive would use a Molex power connector from the power supply.
9.
A. Serial ATA (SATA) drives can have only one drive per cable. That's why they don't
require any jumpers, unlike PATA, which supports up to two drives per cable.
10. B. Add-on display adapters sold today use the PCIe bus. You can then disable the old
adapter in BIOS Setup or leave it enabled for connecting additional monitors.
11. C. A 16x slot is most often used for a display adapter. 1x slots are used for devices requiring
less bandwidth, such as modems. There is no such slot as 2x or 32x on PC motherboards.
12. A. Because a USB 1.1 device has a slower maximum speed than a USB 2.0 port, the device
will be able to function at its full maximum speed, unhindered by the limitations of the port.
13. C. FireWire 400 and FireWire 800 are logically compatible (except for the speed, which is
limited to the lower of the two's capabilities), but physically an adapter is required.
14. B. Circuit boards, including DIMMs, should be handled by the edges only whenever possible.
15. D. Electrostatic discharge, or static electricity, can ruin a circuit board. An antistatic bag
protects against ESD.
16. A. DIMMS are inserted perpendicular to the motherboard.
17. B. Parallel ATA drives have a master/slave cable select setting that you control with a jumper.
18. B. A new hard disk needs a drive bay in which to mount it. A PCIe slot would hold a circuit
board, not a drive.
19. D. Except in the Disk Management utility, Windows cannot see new hard drives until they
have been partitioned.
20. B. NTFS is the best fi lesystem to use in most cases. FAT16 is a very old fi lesystem that is
now obsolete. CDFS is the fi lesystem on CD-ROMs. FAT12 is the fi lesystem used on fl oppy
disks, now obsolete.
