Types of Networks Quiz

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.

• 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.
