A
Wide Area Network (WAN) is a type of computer network that covers
large geographical areas, such as regions, countries, or even continents. It connects multiple
Local Area Networks (LANs) and other smaller networks over long distances using communication technologies such as
leased lines, satellite links, and fiber-optic connections. Large organizations and service providers use WANs to enable communication and data sharing between offices located in different cities or countries. The
Internet itself is the most prominent example of a
WAN.

Ethernet is a
networking technology or protocol used mainly for
wired LAN communication, not a type of large-area network.
·
