A Wide Area Network (WAN) is designed to connect computers and networks over large geographic distances. This type of network can span cities, countries, or even continents, utilizing various transmission technologies such as leased lines, satellite links, and public infrastructure. WANs are essential for businesses and organizations that operate in multiple locations and need to send data across vast distances efficiently.

In contrast, a Local Area Network (LAN) is limited to a small geographic area, typically covering a single building or a group of nearby buildings. A Personal Area Network (PAN) is even smaller, generally used for connecting devices in close proximity, such as Bluetooth devices. A Home Area Network (HAN) pertains specifically to a network within a home, connecting personal devices like computers, smartphones, and smart home devices, but it remains limited to the home environment. Therefore, WAN is the correct choice for connecting computers over extensive distances.
