2.7 – Compare and contrast Internet connection types, network types, and their features Flashcards
Which of the following is a group of Windows desktop computers located in a small area? ❍ A. LAN ❍ B. WAN ❍ C. PAN ❍ D. MAN
A local area network (LAN) is a group of computers, such as a SOHO network
located in a small area. A wide area network (WAN) is a group of one or more
LANs spread over a larger geographic area. A personal area network (PAN) is
a smaller computer network used by smartphones and other small computing
devices. A metropolitan area network (MAN) is a group of LANs in a smaller
geographic area of a city.
Which Internet service makes use of PSTN? ❍ A. Dial-up ❍ B. ISDN ❍ C. DSL ❍ D. Cable Internet
A. Dial-up Internet connections make use of the public switched telephone
network (PSTN) and POTS phone lines. ISDN was developed to meet the
limitations of PSTN. DSL provides faster data transmissions over phone lines
(or separate data lines). Cable Internet is a broadband service that offers higher
speeds than DSL; it is provided by cable TV companies.
You have been tasked with setting up a small office with the fastest Internet
service possible. There is no fiber optic availability in the area because of the
rocky, hilly terrain. Which Internet service will typically offer the best data
transfer rates?
❍ A. WMN
❍ B. FTTP
❍ C. DSL
❍ D. Cable Internet
❍ E. Fixed wireless
D. The Internet service with the best data transfer rates will typically be cable
Internet. Cable Internet service is generally “faster” than DSL. WMN stands for
wireless mesh network, a type of network that uses multiple access points—but
it is not an Internet service. FTTP stands for fiber to the premises, which is not
available in the scenario. Fixed wireless (or line-of-sight wireless Internet service)
can offer very high data transfer rates, but it requires an unobstructed view of the
provider’s tower. This is probably not an option due to the rocky, hilly area where
the customer’s office resides.
