Difference between LAN and WAN
Definition: LAN is a computer network that covers a small geographic area, like a home, office, school or group of buildings. Again, WAN is a computer network that covers a broad area like any network whose communications links cross metropolitan, regional or national boundaries over a long distance.
Ownership: LAN is typically owned, controlled and managed by a single person or organization. On the other hand, WANS are not owned by any one organization but rather exist under collective ownership and management over long distances.
Data transfer rates: LANs have a high data transfer rate but WANs have a lower data transfer rate as compared to LANs.
Set-up costing: The costing of LAN set-up is not very expensive. On the other hand, the set-up costing of WAN is higher.
Maintenance costs: LAN covers a relatively small geographical area and is easier to maintain at relatively low costs. But, Maintaining WAN is difficult because of its wider geographical coverage and its maintenance costs.
Example: Network in an organization can be a LAN. Again, internet is the best example of a WAN.
