A. A LAN, or large area network, uses leased lines to connect computers in distant locations such as different cities.

B. A LAN, or local area network, is a collection of networked computers in a single room or a group of rooms in a building.

C. A WAN, or wide area network, is made up of numerous different local network segments and can stretch across large distances.

D. A WAN, or wide area network, uses switches but not routers.

Explanation / Answer

B and C. A LAN, or local area network, is usually a small collection of computers on a single network segment, with computers attached to each other through one or more switches. You can find LANs in a home, small office, or office building. A WAN, or wide area network, can encompass many network segments, routing traffic across large distances using leased lines or public telephone lines. The largest WAN in the world is the Internet.
