True/False
1. Laptop computers use the same memory modules as desktop computers.
UV
False—The memory chips may be the same, but laptop computers use SODIMM memory
modules, which are significantly smaller than standard DIMM modules and are not
interchangeable.
2. A wireless network adapter might be installed in a mini PCIe slot on a laptop.
True—Laptops have mini PCIe (mPCIe) slots that accept small circuit boards that add various
IA
functions.
3. A facial recognition feature that unlocks a mobile device is an example of biometric authentication.
_A
True—Biometrics are the physical characteristics of someone that make them uniquely
identifiable.
4. Two-factor authentication is an example of mobile device synchronization.
False—Two-factor authentication enhances device security but is not involved in
PP
synchronization.
5. A Bluetooth device must be paired with a mobile device before it can be used.
True—Both devices must be turned on and configured as discoverable before they can be
paired.
RO
6. Of the types of LCD screens, the one with the fastest response time is Vertical Alignment (VA).
False—In-plane switching (IPS) has the fastest response time. VA is the slowest.
7. Most laptop computers use 3.5-inch hard disks, the same as desktops.
VE
False—Most laptop computers use 2.5-inch hard disks, which are different from those used in
desktops.
8. M.2 is a miniature version of a PCIe card designed for laptops.
False—M.2 is an interface for solid-state storage. mPCIe is the miniature version of a PCIe card.
D?
9. The Wi-Fi antenna in a laptop is typically located in the screen assembly.
True—The Wi-Fi antenna typically runs around the outer bezel of the screen.
10. If a laptop's display is very dim and difficult to read, the inverter may be faulty.
??
True—The inverter is the component that converts low-voltage DC power to the higher-voltage
AC power needed to power a CCFL backlight.
, Multiple Choice
11. The process to synchronize a Bluetooth device to a mobile device is called ______.
ST
a. Tethering
b. Enabling
c. Pairing
d. None of the above
Answer C. Pairing is also known as linking.
UV
12. Which of these is a common use for NFC?
a. Navigation
b. Paying by credit card
c. Making a phone call
d. Watching a video
IA
Answers B. NFC stands for near-field communication; one common use is to collect credit card
information by swiping the card within a few inches of a processing terminal.
13. A laptop computer’s display is badly damaged. In addition to the LCD screen needing replacement,
_A
which other components might also need to be replaced? (Choose all that apply.)
a. CPU
b. Wireless antenna
c. Webcam
d. SODIMMs
PP
Answers B, C. The display on almost any laptop includes two additional components besides the LCD
screen: a wireless antenna and a webcam. By replacing the entire display subsystem, all three
components are replaced at the same time.
RO
14. A mobile device with a touchscreen uses which of the following as an overlay on the display?
a. Randomizer
b. Digitizer
c. Wi-Fi antenna
d. Webcam
Answer B. A digitizer is the touch-sensitive layer over the display that translates touch into input
VE
commands.
15. Which type of storage is the fastest and lightest weight, making it an attractive choice for mobile
devices?
a. DVD
D?
b. HDD
c. SSHD
d. SSD
Answer D. A solid-state drive (SSD) is a small circuit board with no moving parts. HDD is a mechanical
drive; SSHD is a hybrid mechanical/solid state. DVD is an optical drive.
??
16. A user wants to add multiple monitors and more USB ports to their laptop. What device should they
purchase?
a. external keyboard
, b. surge suppressor
c. uninterruptible power supply (UPS)
d. port replicator
ST
Answer D. A port replicator expands the capability of a portable computer by adding expansion slots
and input/output ports.
17. Which type of mobile device is most likely to use a Lightning connector?
a. Windows laptop
UV
b. iPhone
c. Chromebook
d. Android phone
Answer B. iOS devices such as iPhones typically use the Lightning connector.
18. Which of these USB cables can carry both data and power?
IA
a. USB-B
b. USB-A
c. USB 3.1
_A
d. USB-C
Answer D. USB-C cables can carry power; USB-A and USB-B cannot. USB 3.1 is a standard for
transmission, not a cable type.
19. Which type of laptop display does not have an inverter?
a. OLED
PP
b. LED
c. IPS
d. TN
Answer C. OLED generates its own light, so it does not need an inverter.
