Laajaverkkojen, also known as Wide Area Networks (WANs), are telecommunications networks that extend over a large geographical area. Unlike Local Area Networks (LANs) which are confined to a small area like a home or office, WANs connect multiple LANs across cities, countries, or even continents. This interconnection allows for the sharing of resources and data between geographically dispersed locations.

The most well-known example of a WAN is the Internet, a global network of interconnected computer networks. Other examples include private WANs established by corporations to link their various branches or government agencies to facilitate communication and data exchange. WANs typically utilize leased telecommunication lines, satellite links, or public infrastructure like fiber optic cables to establish connections. The technologies employed in WANs are diverse and often involve protocols like MPLS (Multiprotocol Label Switching) and various routing protocols to manage data traffic efficiently. The primary function of a WAN is to enable communication and resource sharing over long distances, making it a crucial component of modern global infrastructure.
