What is the difference between a LAN and a WAN?
- A.LAN and WAN are the same thing
- B.WAN is always faster than LAN
- C.LAN is always wireless
- D.A LAN (Local Area Network) covers a small geographic area like a building or campus with high-speed connections, while a WAN (Wide Area Network) spans large geographic areas connecting multiple LANs, typically using leased lines or internet connections - the internet is the largest WAN
Why D is correct
LAN: local area (building/campus), high speed (Gigabit+), private ownership, low latency. WAN: wide area (cities/countries), lower speed, ISP-provided, higher latency. Also: MAN (Metropolitan), PAN (Personal), WLAN (Wireless LAN), and SD-WAN (software-defined WAN).
