Cyber EOP - Network Types By Mr. B

Understanding Network

Types

From PAN to WAN

Definition of a Network

A network connects multiple devices using IP to share data and resources.
Networks are categorized based on the physical proximity of the devices

●PAN: Personal Area Network

●LAN: Local Area Network

●MAN: Metropolitan Area Network

●WAN: Wide Area Network

Multiple Choice

What does PAN stand for?

• Peripheral Area Network

• Private Area Network

• Personal Area Network

• Public Area Network

Personal Area Network (PAN)

PAN connects two or more devices that are on your person, typically via Bluetooth.

Example: Cell phone connecting to a Bluetooth headset or a mobile computer to a portable
printer.

Future Possibility:

●Covert IP surveillance using Bluetooth-enabled devices, like cameras connected to a wearable NVR.

Multiple Choice

What is a common use case for a Personal Area Network?

• Connecting multiple buildings

• Connecting offices in a city

• Connecting devices across the globe

• Connecting devices on a person's body

Local Area Network (LAN)

A LAN is a network of devices in close proximity, usually within the same building.

Can range from simple setups (2 computers) to large installations (100s of cameras
connected via switches).

Common LAN Installations:

●Schools

●Warehouses

●Hospitals

●Office Buildings

Multiple Choice

Which type of network is typically used within a single building?

• WAN

• LAN

• PAN

• MAN

LAN Example: IP Video Surveillance

Multiple IP cameras connected to an NVR and storage array via switches.

Used for high-traffic environments like large buildings or campuses.

Metropolitan Area Network (MAN)

MAN connects multiple LANs across a metropolitan area using high-speed private networks.

Typically used for campuses or multi-location businesses.

Example:

●A university with several buildings spread across the city connects each building’s LAN
to a central NVR and storage array.

Multiple Choice

Which type of network is typically used for connecting multiple buildings in a university?

• MAN

• LAN

• PAN

• WAN

Wide Area Network (WAN)

WAN connects two or more LANs over large distances, even globally.

Example: Internet connection, point-to-point frame relay, or MPLS from an ISP.

Types of WAN Connections:

●DSL

●Cable

●T1, T3

●OC3 to OC192

Multiple Choice

Which connection type is typically used for high-speed data transfer in WANs?

• Dial-up

• Fiber optics

• Cable

• Ethernet

WAN Circuit Speeds

T1: 1.5 Mbps

T3/DS3: 45 Mbps

OC3: 155 Mbps

OC12: 622 Mbps

OC48: 2.488 Gbps

OC192: 9.6 Gbps

Combining MAN and WAN: Metro Ethernet

Metro Ethernet combines MANs and WANs, offering a high-speed
Ethernet connection directly into your firewall or switch.

Reduces hardware and monthly costs significantly.

Multiple Choice

What is the main advantage of Metro Ethernet offerings?

• Higher costs

• Limited connectivity

• Lower monthly and hardware costs

• Slower speeds

  
  

Conclusion

PAN: Personal devices connected via Bluetooth.

LAN: Devices within the same building.

MAN: High-speed network connecting multiple LANs across a city.

WAN: Network spanning large distances, globally.
