•	Explain the difference between a WAN and LAN and the type of standards and protocols each uses

The major difference between a WAN and a LAN is the geographical area that is covered. A LAN connects workstations, printers, servers, and other devices within a building or other small area. A WAN is used to connect multiple LANs, typically over a large geographical area. The primary characteristics of a WAN include the ability to connect devices separated by wide geographical areas, the use of service companies to make these connections, and the serial connections used to access bandwidth.
