Study Notes
Types of Networks
- Personal Area Network (PAN): Wireless network for personal devices like smartphones and tablets within a small range.
- Local Area Network (LAN): Connects devices in limited areas such as homes, schools, or offices.
- Wide Area Network (WAN): Covers a large geographical area, typically connecting multiple LANs, often used by organizations.
- Metropolitan Area Network (MAN): Network that spans a city or college campus, interconnecting several LANs.
- Wireless Local Area Network (WLAN): Wi-Fi network variant of LAN, allowing wireless connectivity.
- Storage Area Network (SAN): Specialized network aimed at providing access to consolidated, block-level data storage.
- System Area Network: Links together high-performance computer nodes in a cluster.
- Home Area Network (HAN): Small network within a home to connect personal devices.
- Enterprise Private Network (EPN): Built by organizations to interconnect various LANs within a company.
- Campus Area Network: Similar to MAN, but typically within a school or university campus.
- Virtual Area Network: Uses virtualization technologies to create logical, rather than physical, networks.
- Passive Optical LAN (POLAN): Utilizes optical fiber infrastructure for data transmission in a LAN setting.
