A Wide Area Network (WAN) is a telecommunication network that connects multiple local area networks (LANs) over large geographical distances, enabling communication and data exchange between offices and facilities in different regions or countries. Essential for companies with distributed operations, WANs utilize various communication channels such as leased lines, satellite links, and internet connections for reliable data transfer. Key benefits include supporting remote work, facilitating global collaboration, improving resource sharing, and providing centralized access to applications and databases. By leveraging a WAN, businesses can enhance operational efficiency, streamline communication, and foster collaboration among geographically dispersed teams, driving growth and innovation.
