Explain the difference between a local area network (LAN) and a wide area network (WAN).

Explain the difference between a local area network (LAN) and a wide area network (WAN).

• A. A LAN spans large distances; a WAN covers a small geographic area
• B. A LAN uses only wireless connections; a WAN uses only copper cables
• C. A LAN covers a small geographic area; a WAN spans larger distances, often using multiple networks and service providers
• D. A LAN is for servers; a WAN is for end-user devices

Answer: (C)

The main idea here is how far a network reaches and how it’s typically put together. A local area network is confined to a small area—like a single building, a campus, or a small business—often owned and operated by one organization, with high data speeds and technologies such as Ethernet and Wi‑Fi. A wide area network, on the other hand, covers large distances—between cities or countries—and usually connects multiple LANs. It often relies on service providers and public networks, using technologies like leased lines, MPLS, or the Internet to link those LANs together. That’s why the best description says a LAN covers a small geographic area while a WAN spans larger distances and typically involves multiple networks and service providers. The other options don’t fit because: a LAN is not defined by spanning large distances; LANs can be wired or wireless, and WANs can use various media, not only copper; and both LANs and WANs can support servers and end-user devices, so labeling one as exclusively for servers and the other for end users isn’t accurate.
