B

Question 2

What is the difference between a local area network (LAN)and a wide area network (WAN)? Give an example of how each one could be used in businesses.

Answer 2

A local area network (LAN)connects computers that reside in a single geographic location on the premises of the company that operates the LAN.Wide area networks (WANs)connect computers at different geographic locations.The computers in two separated company sites must be connected using a WAN.With a LAN, the number of connected computers can range from two to several hundred, but they are still in a single location (usually within a building or floor of a building).Most small businesses have a LAN in their office that connects them.A university campus connects all the different buildings on the campus and possibly multiple campuses via a WAN.
