WAN stands for Wide Area Network. In telecommunications, it refers to a network that covers a large geographic area, connecting multiple Local Area Networks (LANs) and other devices that are separated by a great distance. WANs are typically used to connect remote offices or branch locations within a company, or to enable communication between different organizations, such as suppliers and customers. WANs use various technologies such as leased lines, satellite connections, and frame relay networks to connect networks across long distances. WANs can be expensive to set up and maintain, but they provide significant benefits in terms of enabling remote work and collaboration, accessing and sharing data, and improving efficiency and productivity.
