Answers and Explanations
Objective 1.1
1. a. The monitor’s signal cable connects to a 3-row, 15-pin female D-shell connector
at the back of the system unit.
2. a. In a PC-compatible system, each sector holds 512 bytes of data.
3. b. Standard VGA resolution is defined as 720×400 pixels using 16 colors in text
mode, and 640×480 pixels using 16 onscreen colors in graphics mode.
4. b. The system is reset at startup to a predetermined condition. From this state,
it carries out software instructions from its BIOS program. This program is
permanently stored in the ROM memory ICs located on the system board.
5. d. The Basic Input/Output System (BIOS) program contains the basic instructions
for communications between the microprocessor and the various input
and output devices in the system. The MBR is a special program used by BIOS
to load control programs into RAM.
6. a. The ATX system board connector is a 20-pin connector that contains a signal
line that the system board can use to turn off the power supply. This
power-saving feature is referred to as a soft switch.
7. b. In Microsoft systems, each sector holds 512 bytes of data.
8. a. Each track on the surface of a magnetic disk is divided into an equal number
of equal-sized blocks called sectors. The number of sectors on a track can range
from 8 to more than 60, depending on the disk and drive type, and the operating
system software used to format it.
9. c. The video output connector is a 3-row DB-15 female connector used with
analog VGA displays.
10. c. PC-AT compatibles featured a rechargeable battery to the system board to
maintain the information stored in CMOS when the system was turned off.

advanced software configuration function to their chipsets along with the system’s
Real-Time Clock (RTC) function. The RTC keeps track of time and date
information for the system.
12. a. Cache memory is a fast RAM system used to hold information that the
microprocessor is likely to use.
13. d. The system’s configuration settings are the system’s main method of getting
information about what options are installed. They must be set to accurately
reflect the actual options being used with the system.
Hardware Domain 1.0: Installation, Configuration, and Upgrading 59
14. c. When turned on, a PC begins carrying out software instructions from its
BIOS program, which is permanently stored in the ROM BIOS memory IC
located on the system board. The information stored in the IC represents all
the inherent intelligence that the system has until it can load more data from
another source, such as a disk drive or remote server computer.
15. d. When a PC is turned on, the system is reset to a starting condition and
begins carrying out software instructions from its BIOS program. First, the
BIOS performs POST to verify that the system is operating correctly. Next, it
places starting values in the system’s programmable devices. This process is
called initialization. Finally, the BIOS performs the bootstrap.
16. a. The BIOS software (programming) and hardware (the ROM chip) are
referred to as firmware. Some I/O devices, such as video and network adapter
cards, have additional firmware that act as extensions to the system’s BIOS.
17. b. The BIOS performs a series of diagnostic tests (called POST, or Power On
Self Test) on the system to verify that it is operating correctly. While performing
its normal tests and boot-up functions, the BIOS displays an active RAM
memory count as it is being tested.
18. c. The VGA/SVGA adapter on the back of the computer has a 15-pin, 3-row
female D-shell connector.
19. d. Traditionally, most external CD-ROM drives have employed SCSI interface
connectors.
20. d. A typical CD can hold 680MB of programs and data on a single, inexpensive,
removable media.
21. c. In PC systems, the cable can provide for one or two floppy drives that will
automatically be recognized as logical drives A and B by the system. The drive
connected to the very end of the cable will be designated as drive A.
22. b. In a magnetic disk system, information is stored as magnetized spots
arranged in concentric circles around the disk. These circles are referred to as
tracks. Each disk track is divided into an equal number of equal-sized blocks
called sectors. Sectors generally contain 512 bytes.
23. a. A VGA resolution is defined as 640×480 pixels using 16 onscreen colors in
graphics mode and 720×400 pixels using 16 colors in text mode.
24. c. SVGA is available in the format of up to 1,280×1,024 pixels video controller
capabilities. VGA is capable of up to 640×480 pixels. XGA produces up to
1,024×768 resolution. HGA provides 720×348 resolution.
25. d. In AT-compatible power supplies, two 6-wire bundles, typically marked P8
and P9, deliver power to the system board. The physical construction of these
power connectors is identical. They are designed to plug in to the system
board’s P1 and P2 power plugs, respectively.
26. b. In AT and ATX units, the on/off switch is located on the front panel of the
system unit and connected to the power supply by a cable. In the ATX design,
a special soft switch line is included that enables the system to shut itself off
under control of the system software.
27. b, c. (b) PCI slots are available in 32 or 64 bits; ISA slots are 16 bits. (c) PCI
slots are designed shorter.
28. d. There are notches and dots on the various ICs that provide important keys
when replacing a microprocessor. These notches and dots specify the location
of pin 1. This pin must be lined up with the pin 1 notch of the socket.
29. b. The microprocessor is the major component of any system board. It can be
thought of as the brains of the computer system because it reads, interprets,
and executes software instructions, and also carries out arithmetic and logical
operations for the system.
30. a, b. (a) System boards are sometimes referred to as motherboards. (b) Another
name for system boards is planar boards.
31. c. Read-only memory (ROM) contains the computer’s permanent startup programs.
ROM is nonvolatile. Its contents remain with or without power being
applied.
32. a. RAM is a volatile type of memory. Its contents disappear when power is
removed from the memory.
33. d. Dual Inline Memory Modules (DIMMs) are larger 168-pin boards designed
to work efficiently with Pentium-class microprocessors. They use special snapin
sockets that are keyed so you cannot install them backward.
34. d. The BIOS has three main functions: performing the POST, initializing the
system, and seeking and loading an operating system to which it can transfer
control.
35. b. A monitor with a .28 dot pitch has pixels that are located .28mm apart.
36. b. A color monitor employs a combination of three color phosphors (that is,
red, green, and blue [RGB]) arranged in adjacent trios of dots or bars called
pixels, or PELs.
37. b. Resolution can be expressed as a function of how close pixels can be grouped
together on the screen. The closer the pixels to one another, the sharper the
image. This form of resolution is expressed in terms of dot pitch. A monitor
with a .28 dot pitch has pixels that are located .28mm apart.
Hardware Domain 1.0: Installation, Configuration,
38. c. Color CRTs add a metal grid in front of the phosphor coating called a shadow
mask. It ensures that an electron gun assigned to one color doesn’t strike a
dot of another color.
39. b. In most cases, the EIDE connector on the PC-compatible ATX system
board is used for internal CD-ROM drives. The BIOS for these boards also
provides direct CD-ROM drive support.
40. b. The SCSI drives employ host adapter cards that plug into the system board’s
expansion slots. They are referred to as host adapters because most of the
interface’s control circuitry is actually on the drive; therefore, calling the card a
controller would be incorrect.
41. b. The average storage capacity of a CD-ROM disc is about 680MB.
42. c. The power consumption of LCD displays is very low. The screen is scanned
by sequentially activating the panel’s row and column electrodes. The pixels
appear to be continuously lit because the scanning rate is very high. The electrodes
can be controlled using very low DC voltage levels.
