Which statement best describes a Local Area Network (LAN)?

• A. WAN spans large geographic areas (cities or countries).
• B. LAN covers a small area such as a building.
• C. LAN requires satellite links.
• D. WAN is faster and more private than LAN.

Answer: (B)

A Local Area Network is a network that connects devices within a small geographic area, such as inside a single building or campus. It uses high‑speed connections like Ethernet or Wi‑Fi and is usually owned and managed by one organization, which helps provide faster data transfer and tighter control over security. This contrasts with a Wide Area Network, which spans larger areas—cities or countries—and often relies on rented or public telecom links. Satellite connections are more typical of WAN setups rather than LANs. Because LANs operate over a limited space with private infrastructure, they tend to be faster and more private within that local area. So, describing a LAN as covering a small area such as a building is the best fit.
