CEVAP:

A wide area network (WAN) is a computer network that connects multiple LANs that are located in different geographical regions. Typically, WANs are built by using leased telecommunication circuits.

WANs are very popular and widely used networks as they provide a convenient way to share, exchange, and manage data among organizations and individuals. By connecting different LANs together, computers in one location can communicate with the other computers at other sites.
