2.7 Network Types

Question 1

What does LAN stand for?

Answer 1

Local Area Network

LANs connect devices within a small physical area.

Question 2

What is a LAN?

Answer 2

A network that connects devices within a small physical area, such as a single floor, office, or group of nearby buildings.

LANs typically offer high speeds and low latency.

Question 3

Which network type offers the fastest speeds?

Answer 3

LAN

LANs are designed for high-speed connectivity.

Question 4

What does WAN stand for?

Answer 4

Wide Area Network

WANs connect locations across larger distances.

Question 5

What is a WAN?

Answer 5

A network that spans long distances, connecting locations across cities, states, or countries.

WANs can cover vast geographic areas.

Question 6

How do WAN speeds compare to LAN speeds?

Answer 6

WANs are generally slower than LANs.

This is due to the greater distances and technologies involved.

Question 7

What technologies can WANs use?

Answer 7

• Point-to-point serial connections
• MPLS networks
• Terrestrial fiber
• Non-terrestrial (satellite) communication

These technologies facilitate long-distance communication.

Question 8

What does PAN stand for?

Answer 8

Personal Area Network

PANs are designed for close-range device connectivity.

Question 9

What is a PAN?

Answer 9

A small, specialized network designed for devices close to an individual.

PANs typically cover a range of a few meters.

Question 10

What technologies are commonly used in PANs?

Answer 10

• Bluetooth
• Infrared
• Near Field Communication (NFC)

These technologies enable short-range communication.

Question 11

Give examples of PAN devices.

Answer 11

• Wireless headsets
• In-car systems
• Health or fitness devices

These devices often connect via Bluetooth or NFC.

Question 12

What does MAN stand for?

Answer 12

Metropolitan Area Network

MANs cover larger geographic areas than LANs but smaller than WANs.

Question 13

What is a MAN?

Answer 13

A network that covers a single geographic area such as a city.

MANs are often used by organizations within a city.

Question 14

What technologies are commonly used for MANs today?

Answer 14

• Metro Ethernet
• Municipal fiber infrastructure

These technologies provide high-speed connectivity within metropolitan areas.

Question 15

What does SAN stand for?

Answer 15

Storage Area Network

SANs are specialized for data storage solutions.

Question 16

What is a SAN?

Answer 16

A high-speed, isolated network dedicated to storage repositories.

SANs are used to connect storage devices to servers.

Question 17

What type of access does a SAN provide?

Answer 17

Block-level access.

This allows for efficient data transfer between servers and storage.

Question 18

Why are SANs used?

Answer 18

To efficiently transfer large amounts of data between servers and storage devices.

SANs optimize data management and retrieval.

Question 19

What does WLAN stand for?

Answer 19

Wireless Local Area Network

WLANs provide wireless connectivity within a local area.

Question 20

What is a WLAN?

Answer 20

A LAN that uses wireless (802.11) technology instead of cables.

WLANs enable mobility and flexibility in network access.

Question 21

How can the range of a WLAN be extended?

Answer 21

By adding additional wireless access points.

This helps to cover larger areas and improve connectivity.
