Which of these best describes a LAN?
Answer: D
Correct answer: A network covering a small area such as an office or building
A LAN, or Local Area Network, connects devices within a small area - a room, a building, a campus - typically over Ethernet cable or Wi-Fi, and typically owned and administered by one organisation. The classification by geographic scale runs: PAN for a personal area of a few metres, as with Bluetooth; LAN for a building or campus; MAN for a metropolitan area such as a city; and WAN for anything larger, of which the internet is the largest example. The differences are not only of size. A LAN has high bandwidth, low latency and low error rates because the distances are short and the medium is owned; a WAN uses leased lines or public infrastructure and is slower and less reliable in proportion. A VPN creates an encrypted tunnel across a public network so that a remote device behaves as though it were on a private LAN.
