Review Questions Answers
1. You are sitting at the local coffee shop, enjoying your favorite latte. You pull out your laptop and,

electromagnetic spectrum is your laptop most likely using?
a. Ultraviolet waves

b. The network is intended to be used by one person at a time.
c. The network supports wearable devices.
d. The network is small in geographical coverage.
Answer: b. The network is intended to be used by one person at a time.
Explanation: Networks spanning an area of a few centimeters to several meters around an
individual are called PANs (personal area networks) and are typically used by one person at
a time.
3. When you set up a network at your home with a home router, a few computers, a printer,
multimedia devices, and your smartphone, which of the following statements is true?
a. You can have several PANs, you have one LAN, and you probably have one WAN
connection.

d. You can have several PANs, you have one MAN, and you probably have one LAN
connection.
Answer: a. You can have several PANs, you have one LAN, and you probably have one
WAN connection.
, Explanation: A home network might include multiple work areas, each with its own PAN. The
entire home network is one LAN. The home router supports one WAN connection to the
Internet.
4. Your company’s network administrator mentions during a meeting that she has migrated your
company’s database to a DBaaS. What can you deduce about the database, given just this
information?
a. The database has been backed up.
b. The database is now more secure than it was.
c. The database is stored on a cloud provider’s servers.
d. The database has been archived.
Answer: c. The database is stored on a cloud provider’s servers.
Explanation: The phrase “anything as a service” refers to cloud computing services and is
often adapted to refer to specific types of cloud services, such as DBaaS (database as a
service). When using a cloud service, the actual data or code does not exist on the user’s
computer or datacenter but runs on the cloud provider’s servers and is typically accessed
across the Internet through the user’s browser.
5. When your work computer requests a web page, which device does the computer communicate
with first?
a. Web server
b. Local server
c. Router
d. Switch
Answer: d. Switch
Explanation: A switch is the collection point for the wires that interconnect the workstations
on a LAN. The switch then connects to the router to access the Internet. The router sends the
request across the Internet to a remote web server. A local server would not have the web
page files available.
6. As you’re setting up your home network, you connect one desktop and two laptops to your home
router. You then connect your home router to your cable modem. When you test the connection
with your desktop, the computer can access websites on the Internet. What functions is your
home router providing for your home network?
a. Web server and file server
b. Web server and router
c. Switch and web server
d. Router and switch
Answer: d. Router and switch
Explanation: A switch is the collection point for the wires that interconnect the workstations
on a LAN. A router is the connecting device between LANs and WANs, such as the Internet.
Most home routers provide both these functions in one device.
7. What computer “language” is spoken over the Internet?
a. WAN
b. NaaS
c. TCP/IP
d. DSL
Answer: c. TCP/IP
