How does a LAN connection differ from a WAN connection?

What will be an ideal response?

ANSWER: The following list summarizes the major characteristics of WANs and explains how a WAN differs from a LAN:
* LANs connect nodes, such as workstations, servers, printers, and other devices, in a small geographical area on a single organization's network, whereas WANs use networking devices, such as routers and modems, to connect networks spread over a wide geographical area.
* Both LANs and WANs use the same protocols from Layers 3 and higher of the OSI model.
* LANs and WANs may differ at Layers 1 and 2 of the OSI model in access methods, topologies, and, sometimes, media. For example, the way DSL transmits bits over a WAN differs from the way Ethernet transmits bits over a LAN.
* LANs are mostly owned and operated by the companies that use them. On the other hand, WANs are usually owned and operated by telcos (telecommunications carriers), also known as NSPs (network service providers), such as AT&T, Verizon, Spectrum, and Comcast. Corporations lease WAN connections from these carriers, often with payments based on the amount of bandwidth actually used.
