Types of Computer Networks

Computer networks are classified based on geographical area, scale, and purpose.

1. Personal Area Network (PAN)

• Description: Small network for connecting personal devices within a short range (a few meters).

• Characteristics: Wireless or wired, limited coverage.

• Examples: Bluetooth devices, USB-connected devices, smartphones paired with laptops.

2. Local Area Network (LAN)

• Description: Network covering a small geographical area, such as a home, office, or building.

• Characteristics: High-speed, usually wired or Wi-Fi.

• Examples: Office LAN connecting PCs, printers, and servers.

3. Metropolitan Area Network (MAN)

• Description: Network covering a city or metropolitan area.

• Characteristics: Connects multiple LANs, medium-range coverage, higher speed than WAN.

• Examples: City-wide Wi-Fi networks, university campus networks.

4. Wide Area Network (WAN)

• Description: Network that spans large geographical areas, often countries or continents.

• Characteristics: Slower than LAN, can connect multiple LANs via routers and leased lines.

• Examples: Internet, corporate WAN connecting branches globally.

5. Campus Area Network (CAN)

• Description: Connects multiple LANs within a limited geographical area such as a campus or business park.

• Characteristics: High-speed network, usually managed by a single organization.

• Examples: University networks, corporate campuses.

6. Storage Area Network (SAN)

• Description: Dedicated network for storage devices and servers.

• Characteristics: High-speed, reliable access to centralized storage resources.

• Examples: Enterprise data centers using SAN for storage management.

Key Points

• Networks are categorized based on size, coverage, and purpose.

• PAN is smallest, WAN is largest in scale.

• LAN and CAN are common in offices and campuses.

• SAN is specialized for data storage and management.
