What is WAN?
A Wide Area Network (WAN) connects multiple Local Area Networks (LANs) that are geographically separated. It uses various technologies like leased lines, satellite links, and the internet to enable communication between these disparate networks, allowing users and computers in one location to communicate with those in other locations. Think of it as a super-connector, enabling communication even when LANs are spread across cities, countries, or even continents.
