Which type of network is typically used to connect devices within a building or campus?

• A. LAN (Local Area Network)
• B. WAN (Wide Area Network)
• C. MAN (Metropolitan Area Network)
• D. VPN (Virtual Private Network)

Answer: (A)

A Local Area Network is designed to connect devices within a small, defined area like a building or campus. It supports high speeds and low latency, and is typically owned and managed by a single organization, using wired Ethernet and wireless Wi‑Fi to link computers, printers, servers, and other devices.

In comparison, a Wide Area Network covers much larger distances—across cities, states, or countries—often using leased lines or public networks. A Metropolitan Area Network spans a city or campus-sized area but is larger than a single building. A VPN isn’t a type of physical network by size; it’s a secure method to connect devices or networks over the public internet.

So for within-building or campus connectivity, the Local Area Network is the typical choice.
