M2Q2: Network Types

Question 1

LANs cover smaller geographic regions than WANs.

A. TRUE
B. FALSE

Answer 1

A. True

Explanation: Local Area Networks (LANs) are small networks that are local to a house, office, or small group of buildings. Wide Area Networks (WANs) are the long haul networks that connect LANs to other LANs. WANs can span across entire cities and countries and therefore cover a much larger geographic region than LANs do.

Question 2

What is the smallest type of network that traditionally uses short range wireless technology such as Bluetooth.

A. CAN
B. LAN
C. MAN
D. PAN

Answer 2

D. PAN

Explanation: The Personal Are Network (PAN) covers the area around a person, typically uses shortrange wireless and is the smallest of all the network types.

Question 3

The WLAN, WWAN and PAN are similar in that all three types of networks use this type/category of media.

A. Wireless
B. Fiber Optics
C. Wired
D. Copper

Answer 3

A. Wireless

Explanation: Wireless LANs (WLANs) use WiFi for wireless access to the local network, Wireless WANs (WWANs)use long haul wireless technology such as cellular to wirelessly connect over long distances, and Personal Area Networks (PANs) use shortrange wireless such as Bluetooth to connect peripherals to a host computer.

Question 4

This type of network is usually comprised of multiple LANs and describes the switched network infrastructure of a school, institution, or military base.

A. MAN
B. CAN
C. SAN
D. PAN

Answer 4

B. CAN

Explanation: Campus Area Networks (CANs) describe a networks in which multiple LANs share the same geographic area and are usually inter-connected via high speed switches. Campus Area Networks are much larger than regular LANs the term is normally assigned to the swtiched networks of institutions or college campuses.

Question 5

This type of network is composed of both LANs and WANs.

A. MAN
B. CAN
C. SAN
D. PAN

Answer 5

A. MAN

Explanation: Metropolitan Area Networks (MANs) span across multiple city blocks and even between cities connecting geographically separated LANs so they can function as one cohesive network. A good example of a MAN is the network of a local city government.

Question 6

This type of network can span across cities and countries.

A. DAN
B. FRAN
C. WAN
D. WLAN

Answer 6

C. WAN

Explanation: Wide Area Networks (WANs) are the long haul networks that connect LANs to other LANs. WANs can span across entire cities and countries.
