One way to categorize networks is to divide them into local$-$area networks $($LAN$)$ and wide$-$area networks $($WAN$).$ LANs typically are connected workstations, printers, and other devices within a limited geographic area such as a building. All the devices in the LAN are under the common administration of the owner of that LAN, such as a company or an educational institution. Most LANs today are Ethernet LANs. WANs are networks that span a larger geographic area and usually require the services of a common carrier. Examples of WAN technologies and protocols include Frame Relay, ATM, and DSL$.$
