1.4 – Compare and contrast characteristics of various types of other mobile devices Flashcards
Which of the following is not a mobile device? ❍ A. Tablet ❍ B. Smartphone ❍ C. Desktop PC ❍ D. E-reader
C. The desktop PC is not a mobile device. It is a stationary computer that is
meant to stay at a person’s desk. Tablets, smartphones, and e-readers are all
examples of mobile devices
Which type of memory do most mobile devices store long-term data to? ❍ A. LPDDR4 ❍ B. SATA magnetic disk ❍ C. SATA SSD ❍ D. Solid-state flash memory
D. Most mobile devices store their long-term data to solid-state flash memory.
They do not use SATA as the method of connectivity. LPDDR4 is a common type
of RAM used in mobile devices for short-term storage.
You have been tasked with connecting a wireless earpiece to a smartphone.
Which technology would you most likely use?
❍ A. Wi-Fi
❍ B. NFC
❍ C. 3.5 mm
❍ D. Bluetooth
D. When connecting an earpiece (those little cricket-looking devices) to a smartphone, you would most likely use Bluetooth—just remember that most of them
have a 30-foot range (10 meters). Wi-Fi is less likely to be used; it is more likely to
be used to connect the smartphone to the LAN and ultimately to the Internet. NFC
(discussed in the next section) is used to transmit data between mobile devices in
close proximity to each other. 3.5 mm refers to the audio port on a mobile device.
It is quite possible that a user will utilize a wired headset, but the question focuses
on wireless.
You have been tasked with setting up a device for a salesperson’s vehicle. It
should be able to display maps and give directions to the person while driving.
Which of the following devices would perform these tasks? (Select the two best
answers.)
❍ A. GPS
❍ B. Smart camera
❍ C. Smartphone
❍ D. E-reader
❍ E. VR headset
A and C. A standalone GPS device or a smartphone (equipped with a GPS app)
would do the job here. Both can display maps and give directions to a person
while driving. The other devices are not designed to function in this manner.
