A WAN, or Wide Area Network, connects computers and devices across large geographic areas, such as cities or countries. It enables communication between distant systems through public or private networks.
For example, surveillance companies use WANs to link multiple remote locations to a central monitoring center. This setup allows users to access video feeds and manage security systems from anywhere.
Unlike LANs, which operate in a local area, WANs cover broader distances and often rely on leased lines, satellites, or the internet. As a result, they support scalability and real-time data sharing.
By using WANs, organizations ensure connectivity and centralized control across distributed environments.
