Which characteristic of WANs differentiates them from LANs?

WANs, or Wide Area Networks, are characterized by their ability to cover broader geographic areas compared to LANs, or Local Area Networks. While a LAN typically connects devices within a limited area such as a home, office, or building, a WAN connects multiple LANs that may be situated in different cities, countries, or even continents. This extensive reach allows WANs to facilitate communication and data transfer over long distances, enabling organizations with multiple locations to operate as a cohesive unit.

This distinction in coverage area is crucial because it highlights the primary purpose of WANs as networks designed to connect disparate locations, whereas LANs are primarily focused on local connectivity. The scope of a WAN necessitates the use of various transmission methods, including leased lines, satellite links, and public networks, to ensure effective communication over these vast distances. This fundamental characteristic is what sets WANs apart and underscores their role in global connectivity.
