Storage Area Network (SAN)

A high-speed network connecting storage devices to servers and other computers, allowing for efficient access to large amounts of data.

Wireless Local Area Network (WLAN)

A network connecting devices within a localized area, typically in a building or small campus, using wireless technology (802.11 standards).

Metropolitan Area Network (MAN)

A network infrastructure connecting locations within the same city, often using Ethernet connections and fiber optic cabling.

Block Level Access

Block level access to storage devices allows for efficient reading and writing of data, similar to how your computer interacts with its hard drive.

Study Notes

Network Types

  • LAN (Local Area Network): Connects devices within a building or group of nearby buildings. High bandwidth Ethernet and 802.11 wireless networks are common. Devices are close, so communication speed is high.

WAN (Wide Area Network)

  • WAN (Wide Area Network): Connects locations across cities, countries, or globally. The distance necessitates slower speeds than LANs. Various technologies like point-to-point serial connections, MPLS, fiber optic cables, and satellite links are used.

PAN (Personal Area Network)

  • PAN (Personal Area Network): Connects devices within a person's immediate vicinity (e.g., earbuds, headphones, car audio). This often includes Bluetooth, infrared, or NFC technologies for connecting mobile devices to car audio systems or creating workout reports.

MAN (Metropolitan Area Network)

  • MAN (Metropolitan Area Network): Connects locations within a city or metropolitan area. Distances are longer than LANs, but shorter than WANs. Commonly uses metro Ethernet, with service providers handling the link between sites. Fiber optic cables are heavily used. Governments often use MANs with their already existing infrastructure.

SAN (Storage Area Network)

  • SAN (Storage Area Network): A high-speed network connecting centralized storage facilities to computers. Provides block-level access (similar to local drives), often for large files and high bandwidth. These networks are usually isolated for optimal performance.

WLAN (Wireless Local Area Network)

  • WLAN (Wireless Local Area Network): Wireless network within a building. Uses 802.11 technology. Range is limited and may require additional access points to extend the network.
